Fixed wireless is the operation of wireless communication devices or systems used to connect two fixed locations (e.g., building to building or tower to building) with a radio or other wireless link, such as laser bridge. [1] Usually, fixed wireless is part of a wireless LAN infrastructure. The purpose of a fixed wireless link is to enable data ...
Broadband over power lines (BPL) is a method of power-line communication (PLC) that allows relatively high-speed digital data transmission over public electric power distribution wiring. BPL uses higher frequencies, a wider frequency range, and different technologies compared to other forms of power-line communications to provide high-rate ...
In 1987, Microwave Bypass modified a high-frequency licensed microwave radio (23GHz) and developed the first 802.3 wireless interface, dubbed the EtherWave Transceiver. The result was the first (FCC licensed) point-to-point microwave radio capable of delivering 10 Mbps Ethernet, full-duplex, between local and remote networks up to 4.3 miles apart.
Long-range Wi-Fi is used for low-cost, unregulated point-to-point computer network connections, as an alternative to other fixed wireless, cellular networks or satellite Internet access. Wi-Fi networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [1]
LIN slaves running on RC oscillator will use the distance between a fixed amount of rising and falling edges to measure the current bit time on the bus (the master's time normal) and to recalculate the internal baud rate. INTER BYTE SPACE: Inter Byte Space is used to adjust for bus jitter. It is an optional component within the LIN specification.

Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
Propagation delay is equal to d / s where d is the distance and s is the wave propagation speed. In wireless communication, s=c, i.e. the speed of light. In copper wire, the speed s generally ranges from .59c to .77c. [3] [4] This delay is the major obstacle in the development of high-speed computers and is called the interconnect bottleneck in ...
