Spread Spectrum technology is a wideband radio frequency technique developed
by the military for use in reliable, secure, mission-critical communication systems.
It is designed to trade off bandwidth efficiency for reliability, integrity, and security.
In other words, more bandwidth is consumed than in the case of narrowband
transmission, but the trade off produces a signal that is, in effect, louder and thus
easier to detect, provided that the receiver knows the parameters of the
spread-spectrum signal being broadcast. If a receiver is not tuned to the right
frequency, a spread –spectrum signal looks like background noise. There are two
main alternatives, Direct Sequence Spread Spectrum (DSSS) and Frequency
Hopping Spread Spectrum (FHSS).
14. What is WPS?
WPS stands for Wi-Fi Protected Setup. It provides a simple way to establish
unencrypted or encrypted connections between wireless clients and access point
automatically. User can press a software or hardware button to activate WPS
function, and WPS-compatible wireless clients and access point will establish
connection by themselves. There are two types of WPS: PBC (Push-Button
Configuration) and PIN code.
