An unrelated account owner is someone who does not have WildBlue service (or equipment), but has received charges from WildBlue. An unrelated account owner is also known as a non-customer.
- Account Rebuild Candidate
A WBRES account that malfunctions when the agent tries to carry out some task is potentially a candidate for a rebuild. The malfunction might be an error message, a missing link, or an incorrect status. Not all errors mean the account is a candidate. Agents cannot tell with 100% certainty that an account is a candidate. Agents research the error to decide whether the error affects the customer’s service or their billing. If it does, then they escalate the account to be repaired or rebuilt.

- Arthur C. Clarke
1917-2008 , Arthur C. Clarke was born in Minehead, Somerset, England. In 1936 he moved to London, where he joined the British Interplanetary Society. There he started to experiment with astronautic material in the BIS, write the BIS Bulletin and science fiction. During World War II, as a RAF officer, he was in charge of the first radar talk-down equipment, the Ground Controlled Approach, during its experimental trials. In 1945 he published the technical paper "Extra-terrestrial Relays" laying down the principles of the satellite communication with satellites in geostationary orbits - a speculation realized 25 years later. His invention has brought him numerous honors. Today, the geostationary orbit at 42,000 kilometers is named The Clarke Orbit by the International Astronomical Union.

- C-band
The portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4 to 8 GHz.[1]. It was the first frequency band allocated for commercial ground-to-satellite communications. A typical C-band satellite uses 3.7 - 4.2 GHz for downlink, and 5.925 - 6.425 Ghz for uplink. C band is primarily used for open satellite communications, whether for full-time satellite TV networks or raw satellite feeds, although subscription programming also exists. This use contrasts with direct broadcast satellite, which is a completely closed system used to deliver subscription programming to small satellite dishes connected to proprietary receiving equipment. C band is highly associated with TVRO satellite reception systems, commonly called "big dish" systems since small receiving antennas are not optimal for C-band systems. Typical antenna sizes on C-band capable systems ranges from 7.5 to 12 feet (2.5 to 3.5 meters) on consumer satellite dishes, although larger ones also can be used.
- Channel
A frequency band in which a specific broadcast signal is transmitted. The Federal Communications Commission specifies channel frequencies in the United States. Television signals require a 6 MHz frequency band to carry all the necessary picture detail.
- Charge Period
The days, starting with the cycle date, during which recurring items are charged. The last day of the charge period is one day short of one month later. For example, a charge period goes from the 4th of July to the 3rd of August. If a service call closes on the 4th of August, the charges appear on the next recurring bill.
- Chargeback
A chargeback is a notice from a credit card company, or from a bank, that a customer has disputed a charge made by WildBlue on the payment method. When a customer disputes a charge, they receive a temporary credit from the card company or bank. The credit card company sends the chargeback complaint to WildBlue. WildBlue then has a set amount of time (usually 3 days) from when the complaint is received to either agree to the chargeback or send information showing the charge is valid. A chargeback also provides WildBlue a secure method for investigating the dispute because the payment method numbers are not added to a Customer Ticket. Another benefit is that the card company/bank can credit the customer for interest charges, whereas WildBlue cannot. Agents recommend chargeback only when a non-customer reports charges from WildBlue. Agents cannot recommend it for any other types of billing disputes. Infinys shows a chargeback in Payment History, with a negative amount. Since not all negative payments are chargebacks, the agent must check the product description for the words “chargeback”.
- Circular Polarization
A mode of radio frequency transmission in which the signals are broadcast in a rotating spiral pattern. The polarization can be left-hand (counter-clockwise) or right-hand (clockwise). When circular polarization is used, two separate signals can be broadcast on a single carrier frequency without interfering with each other.

- Dish
Slang for 'Antenna'. A parabolic antenna that is used to collect and focus downlinked and uplinked satellite signals.
- DNS
Domain Name Service/System (DNS) DNS translates host names to IP addresses. In very simple terms, it can be compared to a phone book. Preeminently, DNS makes it possible to assign Internet names to organizations, independently of the physical routing hierarchy represented by numerical IP Addresses. Because of this hyperlinks and internet contact information can remain the same, whatever the current IP routing arrangements may be, and can take a human readable form (i.e. widlblue.net which is easier to remember than an IP address).
- DOCSIS
Data Over Cable System Interface Specification. A worldwide protocol standard used by cable modems to communicate over Coaxial cable networks. This protocol provides compatibility between modems made by different major modem manufacturers.
- Downgrade

- Duplicate Account
More than one WBRES account number that have the same service address, billing address, customer name, or payment authorization. Usually duplicate accounts are for the same customer name, but an agent might mistakenly enter information into the wrong or multiple accounts.
- Duplicate Bill
Customers may perceive that they were billed more than once for a variety of reasons. It is very rare that the back office systems actually create a duplicate bill – a bill covering the same charges for the same billing cycle. A customer may state he is receiving duplicate bills if his credit card number appears on two separate accounts. This happens if an agent adds a payment method correctly to one account, but then adds the same payment method to another account where it does not belong. Another example, a customer orders service from WBDirect, and then cancels. WBDirect charges a $50 restocking fee, and bills the customer. Then the customer goes to their local dealer, orders service, and is installed by the dealer. The Dealer Direct account becomes the account for the monthly service, but the customer may perceive he was billed twice because of the restocking fee.
- Duplicate Charges
Duplicate charges are multiple entries for the same item within one bill. This billing error usually happens because an agent made one of these errors: Took a one-time payment within 72 hours before or after the bill cycle date; Clicked any Submit button more than once; Changed the quantity on a product order
- Dynamic IP address
Dynamic assignment of IP address is implemented using a protocol called, logically enough, the Dynamic Host Configuration Protocol (DHCP). When DHCP is active, it typically works in conjunction with a Domain Name System (DNS) to allow users to find an element's address. Surfing the World Wide Web makes extensive use of these two protocols. When you dialup to your Internet service provider (ISP), DHCP is used to assign an IP address to your connection. When you enter a WWW address in your browser address bar or select a human-readable link on a web page, a DNS is used to turn your URL request into an IP address for transmission. These services can also be used in a directly connected network and in either case are typically administered by the information services (IS) department.

IPSec is short for IP Security, a set of protocols developed by the IETF to support the secure exchange of packets at the IP layer of the OSI model. IPSec is widely used in the implementation of Virtual Private Networks, or VPNs. IPSec support two modes of encryption: Tunnel and Transport. The Transport mode encrypts only the data portion, (or payload), of each packet, but does not encrypt the packet header. Tunnel mode encrypts the header and the payload, and is consider the most secure. IPSec devices share public keys that use the Internet Security Association and Key Management Protocol/Oakley, (ISAKMP/Oakley). The ISAKMP protocol allows the receiving side to obtain a public key and authenticate the sending side using a digital certificate.

The main function of the OMT is to transfer RF to individual transmit and receive ports and to provide a 90 degree opposed (orthogonal)isolation between them using vertical and Horizontal polarization.
- One-time charges
These charges happen once. For example, the activation fee is a one-time charge the customer pays on the day they order service, or the prepaid lease fee.
- One-time Move
A one-time move relocates the service to a new street address. If the customer purchased equipment, they leave the dish in place, and the take the modem (and power supply) and Ethernet cable to the new location. A new dish is sent to the new location. If the customer leases their equipment, they must remove the TRIA from the dish, and send it and the modem (with powers supply) back to WildBlue. A new dish and new modem are sent to the new location. The one-time move process is also used when the service address has a zip code error.

- Partial vs. Full Payment
If a customer in Collections pays a portion of what they owe, they make a partial payment. If a customer pays the total amount of what they owe, they make a full payment. Both payments are allowed; however, any account in Collection cannot be resumed or reconnected until the account is paid in full. Only full payments are taken from payment methods for normal, active accounts.
- PAT
Port Address Translation. A function provided by routers, which allows hosts on a LAN to communicate with the rest of a network (such as the Internet) without revealing their own private IP address. All outbound packets have their IP address translated to the routers external IP address. Replies come back to the router, which then translates them back into the private IP address of the original host for final delivery.
- Payment
Money taken from the authorized payment method, either bank or credit card, to pay the bill.
- Payment Authorization
A payment authorization is the account a customer allows WildBlue to charge for monthly services. This can be a debit or credit card, or a checking or savings account (called an EFT.) Every customer must give an account as a payment authorization because WildBlue does not send printed invoices, and it does not accept checks. All payments are made electronically.
- Payment Authorization End Date
An end date is the last day that WildBlue is authorized to use a credit card or bank account for monthly bills. The end date for a credit card is usually the credit card expiration date. EFT accounts do not show an end date unless it was stop dated.
- Payment Status

Postini helps stop spam, phishing, viruses, directory harvest attacks, with patented, multi-layer technology that delivers unmatched intrusion prevention and protection for WildBlue Email Subscribers.
- POTS
Plain Old Telephone Service. Also referred to as plain old telephone lines. The traidiontional analog telephone system originally designed for voice transmission.
- Pre-pay
Although all WildBlue services are paid month-in-advance, some customers wish to pay the full amount of the agreement in one payment. This is allowed, but WildBlue recommends that the customer call after the first bill cycle so that taxes are computed correctly. If the customer makes changes to the account during the term of the agreement, such as an upgrade or downgrade, they may use their pre-pay balance slower or faster than originally planned.
- Product Description
This section of the bill lists the service package charges (and adjustments if a transitional bill), equipment charges, and activation charges. Early termination fees also appear in this section of a final bill.
- Prorated
A prorated charge is a portion of the normal charge, calculated on a per-day basis. Monthly service charges are prorated whenever a customer transitions their account (upgrade/downgrade, suspend/resume, disconnect), or if they change their bill cycle date.
- Protocol
A set of formal rules describing how to transmit data, especially across a network.
Low-level protocols define the electrical and physical standards to be observed, bit- and byte-ordering and the transmission and error detection and correction of the bit stream.
High-level protocols deal with the data formatting, including the syntax of messages, the terminal to computer dialogue, character sets, sequencing of messages etc. Many protocols are defined by Request For Comment (RFC)s or by Open Systems Interconnect (OSI) published by international standards committees.
- Provisioning
Provisioning connects a customer's equipment to their account.
A provisioned account has the following parts: a WBRES account number with an activation date, a satellite modem, and a connection to the Internet. An installer provisions the account when he installs the dish. This adds the modem’s registration number (MAC address) and the activation date into the WBRES account. Once this information is in the WBRES account, the modem is able to connect to the Internet. When a business specialist rebuilds an account, the new WBRES account is re-provisioned.
- Proxy Server
In computer networks, a proxy server is a server (a computer system or an application program) that acts as a go-between for requests from clients seeking resources from other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server evaluates the request according to its filtering rules. For example, it may filter traffic by IP address or protocol. If the request is validated by the filter, the proxy provides the resource by connecting to the relevant server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it 'caches' responses from the remote server, and returns subsequent requests for the same content directly.
A proxy server has two purposes:
* To keep machines behind it anonymous (mainly for security).
* To speed up access to a resource (via caching). It is commonly used to cache web pages from a web server. This is how the WildBlue network uses proxy servers as part of the Optimizer.

- Recurring charges
These charges appear on the customer’s bill every month. For example, the service package fee, and the monthly equipment lease fee.
- Refund
A refund is when WildBlue returns money to a customer, either to the account the money came from, or by paper check.
- Retail
Selling directly to the person who will use the service. WB Direct, Dealer Direct and Dealer SO are some of the retail channels because WildBlue collects money for the service directly from the customer.

Two separate accounts are required. The customer is required to fulfill their original customer agreement before asking for a seasonal suspension.
- Security Password
This is the password used to validate the customer when they call WildBlue. We recommend the mother’s maiden name, but it can be any word. If a security password is not configured, the customer will be required to provide the last 4 digits of the payment method on file.
- Self Care Portal (SCP)
The Self Care Portal (SCP) is a web site where customers can view their electronic bills. They use a special user name and password to access this web page, selected when they ordered their service. This logon is not the same as what they use for their email, nor it is the security information on their account.
- Service Availability Tool
The Service Availability Tool (sometimes called SAT) tells an agent whether WildBlue provides service in a caller’s zip code. SAT is part of the Support Portal, available on the Tools tab. The agent enters the zip code, and the results include some technical specifications about the service, as well as the promotions available in that area. If service is not available, the results will state this.
- Service Loop
A loop of extra cable at least 4 inches in radius, left in specific locations during installation to allow for connector replacement, troubleshooting disconnections, and dish adjustments. Service loops allow work to be done and adjustments made to the system without having to replace complete cable runs due to cable lengths being left too short.

- Solar Outage
Also called Solar Conjuntion. When the sun passes behind a satellite in relation to the earth and the sun's energy momentarily overpowers the satellite signals. This happens two times each year during the spring and fall equinox. An outage is temporary and service is restored when satellite and sun are no longer aligned with the earth.
- Spectrum
The range of electromagnetic radio frequencies used in the transmission of sound, data, and television.
- Spoofing
When a computer within a private network is communicating with a remote computer that has been authenticated once, the two-way communication is called a session, and authentication does not need to be repeated until the session ends. However, if the remote computer uses an “access on demand” connection to the Internet, it is unable to maintain a “session”, and would need to authenticate for each message. Spoofing is a function provided by routers to maintain the session. To do this the router responds to “keep session alive?” messages on behalf of the remote computer.
- Spot Beam
A signal from an orbiting satellite that is specially concentrated in power, typically by a high-gain antenna, so that it will cover only a limited geographic area on earth. Spot beams are used so that only earth stations in the intended spot beam reception area can receive the satellite signal.
- SSL
The Secure Sockets Layer protocol is an application layer security protocol developed for the purpose of sending documents securely over the Internet. SSL uses private keys to encrypt data that is transmitted over the SSL connection. Netscape, Internet Explorer, and most web browsers used today support the SSL protocol. Many web sites use this protocol to secure user’s private data, such as Internet banking sites and sites that provide credit card transactions.
- SSL VPN
An SSL VPN (Secure Sockets Layer virtual private network) is a form of VPN that can be used with a standard Web browser. In contrast to the traditional IPSec (Internet Protocol Security) VPN, an SSL VPN does not require the installation of specialized client software on end users' computers.
The SSL VPN can be a good choice where trust can be an issue but easy access is also important. Applications include Web-based e-mail, business and government directories, databases for educational institutions, file sharing, remote backup, remote system management and consumer-level e-commerce.
SSL is a protocol for managing the security of message transmission on the Internet. SSL is included as part of both the Microsoft and Netscape browsers and most Web server products. It employs the public-and-private key encryption system from RSA. As TLS (Transport Layer Security), a refinement of SSL, replaces the earlier protocol, an SSL VPN is sometimes referred to as a TLS VPN.
- Stalled Order
An order is stalled when it does not reach a Completed status within 24 hours. Stalled orders have a Pending or Dispatched status after 24 hours.
- Static IP address
Static IP address
Every computer connected to a network (either a company network, or the Internet) is assigned an IP address. This address is how the network finds the computer in order to communicate with it. Normally, on most networks and the Internet, the IP address is assigned to the computer for a short period (called a dynamic IP address.) If the IP address is permanently assigned, it is called a static IP address. Note: Technically speaking, the IP address is assigned to the Network card on the computer. In the case of WildBlue, the network assigns the IP address to the satellite modem.
- Stop Dating
A request to stop using a payment authorization is called stop dating. When a customer changes payment authorizations, the original account is automatically stop dated with the current date. An authorization may be stop dated for other reasons, such as the card is on the wrong account or WildBlue is notified that an account was closed.
- Streaming
A technique for transferring data such that it can be processed as a steady and continuous stream.
Watching a movie is streaming data. Parts of the movie download to your computer, and when you've watched that part, a message is sent to the server to send more parts. It happens very rapidly, so usually there is no break while you are viewing.

- Subnet Mask
A bit mask used to identify which bits in an IP address correspond to the network address (Network ID) and subnet portions (Host ID) of the address. This mask is often referred to as the subnet mask because the network portion of the address can be determined by the class inherent in an IP Address. The address mask has ones in positions corresponding to the network and subnet numbers and zeros in the host number positions
- Sub-network
Subordinate system that is a part of a larger system of interconnected data components or circuits.
- Suspended Account
A suspended account is “on hold.” The equipment is still provisioned; however, the satellite modem does not receive Internet services (browsing and email). The account is not billed, however in the case of suspended for non-pay, the customer still owes money to WildBlue. The customer is still obligated to fulfill their contract.
- Suspended Beam
A beam may be suspended for new customers when it reaches a certain capacity. This helps preserve the best service possible for all of the existing customers. Advances in the network technology may allow a suspended beam to reopen to new customers.
- Suspended because of a Change in Circumstances
A change in circumstances means being deployed by the military or suffering a devastating event. Customers in the military may suspend their service when they receive deployment orders. They must send a copy of their orders to WildBlue. Customers who suffer a devastating event, such as a house fire, may also suspend their service. They must send a statement of loss to WildBlue. These customers are allowed to suspend their service even during the original customer agreement.
- Suspended for Abuse
The Abuse Management Team may suspend a customer’s account when they detect a virus or spam attack, or for other violations of the Acceptable Use Policy. After the customer cleans their computers, the service may be resumed.
- Suspended for Non-Payment
If a customer has a past due account (30 days), Finance suspends the service. Most of the time, the customer did not realize their authorized payment method had expired. The first time the account is suspended for non-payment, an agent can resume it after taking a one-time payment for the full amount.

Traceroute works by increasing the "time to live" value of packets and seeing how far they get, until they reach the given destination; thus, a lengthening trail of hosts passed through is built up.
- Traffic
The volume of transmitted signals on a communications network or channel.
- Transceiver
A transceiver is a combination transmitter/receiver in a single package. Some transceivers are designed to allow reception of signals during transmission periods. This mode is known as full duplex, and requires that the transmitter and receiver operate on substantially different frequencies so the transmitted signal does not interfere with reception. Satellite communications networks often employ full-duplex transceivers at the surface-based subscriber points. The transmitted signal (transceiver-to-satellite) is called the uplink, and the received signal (satellite-to-transceiver) is called the downlink
- Transition Bill
This monthly bill covers the change in the service level. Since customers pay a month in advance, a pro-rated credit appears for the old service level. A pro-rated charge also appears for the new service level, plus the month-in-advance charge. This bill may be larger than a regular bill at the new service level, depending on circumstances. See KB article, Reading a Transitional Bill, for a detailed explanation.
- Transponder
A device in an orbiting communications satellite that receives signals from the Earth, translates and amplifies them on different frequency, and then retransmits them back to Earth.
- TRIA
Transmit Receive Integrated Assembly. It transmits and receives data to and from the WildBlue satellite. It's located on the bottom of the arm of your satellite dish.
- Trojan Horse
A piece of software which appears to perform a certain action, but in fact, performs another. Contrary to popular belief, this action, usually encoded in a hidden payload, may or may not be acutely malicious, but Trojan horses are notorious today for their use in the installation of backdoor programs. Simply put, a Trojan horse is not a computer virus. Unlike such badware, it does not propagate by self-replication but relies heavily on the exploitation of an end-user. It is instead a categorical attribute which can encompass many different forms of codes.
- Twisted Pair
This is the term used to describe the traditional copper cable that is used for short distance communications.
U
- UDP
User Datagram Protocol. Using UDP, programs on networked computers can send short messages sometimes known as datagram’s (using Datagram Sockets) to one another. UDP does not guarantee reliability or ordering in the way that TCP does. Datagram’s may arrive out of order, appear duplicated, or go missing without notice. Avoiding the overhead of checking whether every packet actually arrived makes UDP faster and more efficient, at least for applications that do not need guaranteed delivery. Time-sensitive applications often use UDP because dropped packets are preferable to delayed packets. UDP's stateless nature is also useful for servers that answer small queries from huge numbers of clients. Unlike TCP, UDP is compatible with packet broadcast (sending to all on local network) and multicasting (send to all subscribers). Common network applications that use UDP include the Domain Name System (DNS), streaming media applications such as IPTV, Voice over IP (VoIP), Trivial File Transfer Protocol (TFTP) and online games.
- UHF
Ultra High Frequency. The part of the radio spectrum from 300 to 3000 megahertz, which includes TV channels 4-83, as well as many land mobile and satellite services.
- Unauthorized Payment Method
An unauthorized payment method happens any time a WildBlue account has the wrong information for charging the monthly bill. This can happen when: an agent enters the numbers on the wrong customer account; an agent makes a typo error entering the numbers; a customer ‘borrows’ a payment method (from a friend/relative), and later forgets to update WildBlue with their own account authorization. “Unrelated account owner” and “non-customer” are related terms.
- Unidirectional
Operating or moving or allowing movement in one direction only; "a unidirectional flow"; "a unidirectional antenna"
- UNIX
An interactive time-sharing operating system invented in 1969 by Ken Thompson of Bell Labs. Dennis Ritchie, the inventor of {C}, is considered a co-author of the system. I was the first source-portable Operating System. By 1991, Unix had become the most widely used multi-user general-purpose operating system with built-in TCP/IP in the world. Unix is now offered by many manufacturers and is the subject of an international standardization effort. Unix-like operating systems include AIX, A/UX, BSD, Debian, FreeBSD, GNU, HP-UX, Linux, NetBSD, NEXTSTEP, OpenBSD, OPENSTEP, OSF, POSIX, RISCiX, Solaris, SunOS, System V, Ultrix, USG Unix, Version 7, Xenix. "UNIX" is a registered trademark of The Open Group.
- Unprovisioned
A WBRES account number that is waiting for the activation date and the modem’s registration number (MAC address) to be added.
- Unused Service
This is the portion of the month between the disconnect date and the next bill cycle date. Recall that WildBlue service is paid a month in advance.
- Upgrade
An upgrade is a change in the service level from Value to Select, or Select to Pro. The monthly charge increases; the Thresholds also increase. The number of email accounts also increases with the Pro service level.
- Uplink
The signal path from an earth station to a satellite.
- Upload
To send a file to a server where it will be stored.
When you send an email, it is uploaded to the email server, which then sends it on to the recipient (the person you wrote to.) The email program leaves it on the server until the recipient downloads the email.
Sharing a photo, or a video file, to a website is the same as uploading. It stays on the website's server until you delete it.
- Upsell
The process of selling customer's additional services.
- Upstream
The data path from the subscriber terminal to the Internet Service Provider gateway.
- Upstream Transmit Power
This SVT field displays the power used by the modem to communicate with the satellite on the upstread data path. If this value is too high (shown as a lower negative number), the modem is working too hard to communicate.
- Usenet Groups
Usenet groups are also known as newsgroups, or discussion groups. Users exchange information generally provided in a “chat room”.
- User-downlink
The downstream data-path portion of the user-link. It is used by bent-pipe technology to form half of the complete downstream data-path.
- User-link
The link (either uplink or downlink) between the user terminal and the satellite.
- User-uplink
The upstream data-path portion of the user-link. It is used by bent-pipe technology to form half of the complete upstream data-path.
V
- Validation
Confirming the truthfulness of the caller’s claim as the account holder, or as a certified installer.
- V-band
The frequency range from 50.0 to 75.0 GHz. The V band is not heavily used, except for millimeter wave radar research and other kinds of scientific research. The V band is also used for high capacity terrestrial millimeter wave communications systems. All communications links in the V band require unobstructed line of sight between the transmit and receive point.
- Very High Frequency (VHF)
The part of the radio spectrum from 30 to 300 megahertz, which includes TV channels 2-13, the FM broadcast band, and some marine, aviation and land mobile services.
- Virtual Private Network (VPN)
A Virtual Private Network (VPN) is the most secure way to provide communication between computers on your private network and trusted computers across the Internet. There are three ways that your firewall can secure your VPN communication to the remote computer. First, the firewall can be configured to only trust communications received from certain addresses. Second, a special code can be used to encrypt all communications. The code uses a “key” to encrypt and decrypt the messages. Once the same key is provided to the firewall and remote computer user, the computers can communicate. The encryption key is generally unique in the world, and very difficult to determine by trial and error. This is the main feature of VPNs that make them highly secure. Third and finally, there is: the username and password. When a remote computer meets all three requirements, a VPN is established between the remote computer and the firewall. The remote computer then appears to all computers to be sitting on the local private network. It is “virtually” there. Keep in mind that if the remote computer is a firewall or router, then you are connecting two private networks together so that they appear to be one single private network. This configuration is called a Wide Area Network (WAN), and each private network is called a Local Area Network (LAN). Any number of LANs can be connected together through VPNs to form a single WAN.
- Virus
A computer program that can copy itself and infect a computer without permission or knowledge of the user. However, the term "virus" is commonly used, albeit erroneously, to refer to many different types of malware programs. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or the Internet, or by carrying it on a removable medium such as a floppy disk, CD, or USB drive. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses. A worm can spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a file that appears harmless until executed.
- VoIP
Voice over Internet Protocol (VoIP) is a protocol optimized for transmission of voice through the Internet or other packet switched networks. VoIP is often used abstractly to refer to the actual transmission of voice.
- Volt
The unit of measurement of electrical potential or pressure.
- Voluntary Suspension
After a customer fulfils their original customer agreement, they may ask to suspend their account. There is no minimum or maximum period; however, WildBlue may change this, or may decide to charge a small monthly fee to maintain the account while suspended. One account must always be active.
- VSAT
Very small aperture terminal. Refers to small earth stations, usually in the 1.2 to 2.4 meter range.
W
- Wall Fish
The process of running coaxial cable through a building wall by drilling holes either from the top in an attic or service space, and/or from the bottom in a basement or crawl space, then using a special road, chain, or metal tape to draw the coax along the desire route. To have cable concealed, Wall Fishing is typically an additional cost.
- WAN
A Wide Area Network (WAN) is a communications network that uses such devices as telephone lines, satellite dishes, or radio waves to span a larger geographic area than can be covered by a LAN.
- Watt
A measured unit of electrical power. By definition, one watt is the power consumed in a circuit with one volt applied and one amp of current flow.
- Wavelength
The distance between repeating units of a propagating wave of a given frequency. It is commonly designated by the Greek letter lambda (?). Examples of wave-like phenonomena are light, water waves, and sound waves. Generally measured from crest to crest.
The job of any modem is to convert the digital signal from a computer into a different kind of signal, usually proprietary, that can be transmitted long distances and then be converted back to the original format. Ethernet is a medium for carrying network traffic, just as air carries your voice. The maximum length for an Ethernet cable segment is 300ft or 100m. All Ethernet network communications are converted to some other medium for long distance transmission using a modem.
- WBRES
The Infinys account created for the customer when they order WildBlue service. Every account begins with these letters.
- Wholesale
Selling the service to another company who then sells to the person who uses the service. DISH Network, DirecTV are wholesale partners because they bill their customers for the service; they pay WildBlue a fee for each of their customers.

- WildBlue Optimizer
The WildBlue Optimizer is a software tool designed to enhance the web surfing experience of computers connected to the WildBlue network.
- WildBlue Retail
AT&T, Sales-Only Dealer, WildBlue Direct, and Self-Installing Dealer accounts are all considered WildBlue Retail.
- WildBlue Security Center
WildBlue Security Center is a virus protection software that is provided to all customers free of charge for one year. Provided by F-Secure.
- Wireless Communication
Any broadcast or transmission, which can be received through microwave or radio frequencies without the use of a cable connection for reception.
- Worm
A self-replicating computer program. It uses a network to send copies of itself to other nodes (computer terminals on the network) and it may do so without any user intervention. Unlike a virus, it does not need to attach itself to an existing program. Worms almost always cause harm to the network, if only by consuming bandwidth, whereas viruses almost always corrupt or modify files on a targeted computer.
- Write-off
An accounting term used to describe removing a past-due amount from an account. When a write-off is applied to the past-due amount, the account balance goes to zero. For example, an account is past due $-234.00. A write-off of $234.00 is applied, so the account balance is zero.Infinys shows Write-off balances in the Adjustment history.
A write-off is not the same as a credit, refund, or other adjustment. The customer still owes WildBlue the past-due amount. The write-off is used only as an accounting procedure.
X
- XDSL
Another way of referring generically to any of the DSL (Digital subscriber line variants: ADSL, SDSL, RADSL, IDSL, VDSL.
