SUMMARY:In the early days of 802.11 wireless networking (2001) it was typical for a company to hire a consultant to come in and perform a wireless site survey.
All the 802.11 specifications use the Ethernetprotocol andCarrier Sense Multiple Access with Collision Avoidance (CSMA/CA) for path sharing. The original modulation used in802.11 was phase-shift keying (PSK). However, other schemes, such as complementary code keying (CCK), are used in some of the newer specifications. The newer modulation methods provide higher data speed and reduced vulnerability to interference.
