In telecommunications, data transfer rate is the average number of bits , characters or symbols , or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s).
Enhanced Data Rates for GSM Evolution (EDGE), also known as Enhanced GPRS (EGPRS) or IMT Single Carrier (IMT-SC), is a backward-compatible digital mobile phone technology built as an extension to standard GSM. First deployed in 2003 by AT&T in the United States, EDGE offers a theoretical maximum transfer speed of 384 kbit/s (48 kB/s). [4]
The Universal Mobile Telecommunications System (UMTS) is a 3G mobile cellular system for networks based on the GSM standard. [1] Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology.
The figures below are simplex data rates, which may conflict with the duplex rates vendors sometimes use in promotional materials. Where two values are listed, the first value is the downstream rate and the second value is the upstream rate. The use of decimal prefixes is standard in data communications.
Enhanced Data rates for GSM Evolution (EDGE), also known as 2.75G, Enhanced GPRS (EGPRS), IMT Single Carrier (IMT-SC), and Enhanced Data rates for Global Evolution, is a 2G digital mobile phone technology for data transmission.
Symbol rate or baud rate, the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time; Data-rate units, measures of the bit rate or baud rate of a link; Data transfer rate (disk drive), a data rate specific to disk drive operations
An emergency test alert will go out to cell phones nationwide Wednesday morning, the San Luis Obispo County Office of Emergency Services said in a social media post. But you need to turn on a ...
In all EGPRS modulation and coding schemes, a convolutional code of rate 1/3 is used, and puncturing is used to achieve the desired code rate. [5] In contrast to GPRS, the Radio Link Control (RLC) and medium access control (MAC) headers and the payload data are coded separately in EGPRS. [5] The headers are coded more robustly than the data. [5]
