data rate can reach Mbps of HSDPA, which may prove to be a powerful challenger for WiMAX in providing broadband services to customers at a low cost and high efficiency. As its supporter said in unison, HSDPA has a comprehensive ecosystem that provides competitive services and devices to the market, including USB modems and wireless routers supporting HSDPA. However, they believe that WiMAX still takes a long way to go if it wants to have a significan
transmits a bit rate of (120symbol/s) * (3bit/symbol) =360bps. Analysis ExampleEditIt is a measure of the rate of signal transmission, usually in "baud" (baud) units. The baud rate is sometimes confused with the bit rate, which is actually a measure of the rate of information transmission (messaging rate). The baud rate can be understood as the number of transmission code element symbols per unit of time (rate of transfer of symbols), through different modulation methods can load multiple bits

The following rules describe the frame format defined by the SLIP protocol:(1) The IP datagram ends with a special character called End (0XC0). At the same time, most implementations also pass an end character at the beginning of the datagram in order to prevent line noise before the datagram arrives as a datagram content.(2) if one of the characters in the IP message is end, t
Absrtact: More and more people are complaining about the slow speed of the mobile network. This is an eternal topic, because no matter how fast the mobile network speed can not meet the increasing demand for speed. The era of turtle speed Internet under 14.4K modems has long been forgotten, and now people are asking for instant access to any Web page. Oddly, however, people are complaining about the network itself, not the speed of the Internet. If yo
