ANSI creates standards for networking and communications. It is the U.S. representative to the International Standards Organization (ISO)
Average Revenue Per User
An ITU standard set of communications protocols in which information is transmitted in fixed "cells" of 53 bytes each. Transmission rates supported are typically from 2 Mbit/s to 622 Mbit/s.
In radio wave propagation, attenuation of a radio wave due to dissipation of its energy, i.e., conversion of its energy into another form, such as heat.
A network with a central cabling scheme linking it to other networks. Hosts on networks linked to the backbone can communicate with one another.
Routers designed to be used to construct backbone networks using leased lines. Typically do not have any built-in digital dial-up WAN interfaces.
The information-carrying capacity of a computer or communications channel, such as a telephone line, measured in bits per second.When referring to digital networks, the capacity of a channel in bits/s. When referring to frequencies, the difference between the upper and lower limits of a band. A range of radio, audio, or other frequencies.
A Binary digIT. It is a number in base 2 (binary), which means that it can only be a 0 or a 1. It is used in the expres-sion `bits per second'.
Code Divison Multiple Access. A digital cellular technique invented by Qualcomm. Strictly, a method of multiplexing using orthogonal codes to share a radio channel between multiple signals. Generally used to refer to a family of mobile cellular systems developed by Qualcomm, including CDMA2000 1x-EvDO, one of the ITU-T's global 3G standards. W-CDMA, as used in UMTS, another of the 3G standards, and TD-CDMA, typically used for data applications, use the same underlying technology. Various other radio access networks use CDMA variants as a multiplexing method.
Association of the 26 European PTTs that recommends communication specifications to the ITU-T.
A service available on digital phone networks that tells the person being called which number is calling them. Information about the caller is sent along with the call itself.
A subgroup of network users that is treated as an entity. Member can communicate only with other members of that subgroup.
