13. What is Spread Spectrum?
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.
