throughput than ASCII mode for the same baud rate; each message is transmitted in a
continuous stream (See also ASCII, above).
Sector Antenna
An antenna type that radiates in only a specific direction. Multiple sector antennas are
commonly used in point-to-multipoint situations.
Signal Diversity
A process by which two small dipole antennas are used to send and receive, combining
their results for better effect.
Signal Loss
The amount of signal strength that's lost in antenna cable, connectors, and free space.
Signal loss is measured in decibels. Also referred to as gain loss.
Signal Strength
The strength of the radio waves in a wireless network.
Simplex
A communications circuit or system designed to either transmit data or receive data,
but not both. Broadcast television is an example of simplex communication system. A
television station sends a TV signal but cannot receive responses back from the
television sets to which it is transmitting. The TV sets can receive the signal from the TV
station but cannot transmit back to the station.
Site Survey
A comprehensive facility study performed by network managers to ensure that planned
service levels will be met when a new wireless LAN, or additional WLAN segments to an
existing network are deployed. Site surveys are usually performed by a radio frequency
engineer and used by systems integrators to identify the optimum placement of access
points to ensure that planned levels of service are met. Site surveys are sometimes
conducted following the deployment to ensure that the WLAN is achieving the
necessary level of coverage. Site surveys can also be used to detect rogue access points.
Spectrum
A range of electromagnetic frequencies.
