Fixed wireless services typically use a directional radio antenna on each end of the signal (e.g., on each building). These antennas are generally larger than those seen in Wi-Fi setups and are designed for outdoor use. Several types of radio antennas are available that accommodate various weather conditions, signal distances and bandwidths.
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Local multipoint distribution service (LMDS) is a broadband wireless access technology originally designed for digital television transmission (DTV). It was conceived as a fixed wireless, point-to-multipoint technology for utilization in the last mile. [1] LMDS commonly operates on microwave frequencies across the 26 GHz and 29 GHz bands. In ...
Fixed or local area network: DECT, for local loop; LMDS; IEEE 802.11, originally designed for short-range mobile Internet and network access service, it has emerged as the facto standard for wireless local loop. WiMAX or IEEE 802.16 may become the dominant medium for wireless local loop.
A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. A repeater sited at a high elevation can allow two mobile stations, otherwise out of line-of-sight propagation range of each other, to communicate. [ 1 ]
Or the radio link may be full duplex, a bidirectional link using two radio channels so both people can talk at the same time, as in a cell phone. Cellphone - a portable telephone that is connected to the telephone network by radio signals exchanged with a local antenna called a cell tower.
