Hybrid Access To A Contention-Free Period Channel

摘要

To increase bandwidth, a channel, which normally is limited to contention-free transmissions, is used for other purposes during times when it is not needed for contention-free transmissions. Although the channel is located in a contention-free portion of a beacon cycle, supplemental uses of this channel include the contention-based transmission of data that normally would be sent during a contention portion of the cycle. These transmissions include those made under the CSMA protocol.
