Aironet Wireless Communications, Inc. 2-4 Confidential and Proprietary
Upon successful reception of a complete packet, the PC4500/4800 will inform the host processor that it
has a packet in its buffer. Duplicate packets are filtered out via the use of frame sequence numbers in the
header of each frame.
The implemented RF protocol and media access techniques used by the PC4500/4800 cannot be altered
by the programmer. Variations are limited primarily to setting the operating channel(s), maximum
packet size, packet fragmentation size, flow control, and number of packet retries.
The PC4500/4800 can be set to operate in a direct peer-to-peer mode or as part of an infrastructure
network. An infrastructure network consists of Aironet access points that are interconnected via a
distribution system (which may be wireless or wired).
Beyond the point of determining if the PC4500/4800 is associated with an access point, the RF protocol
is transparent to the driver residing on the host. The PC4500/4800 will automatically maintain an
association and attempt to maintain the best link to the distribution system. The driver should monitor
the association status of the PC4500/4800 to be sure that the association has not been lost.
