This demo can help partners demonstrate to their customers how their employees can be more productive on the road by being able to access their e-mail and other business applications securely even when they're away from the office.
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.
