Coexistence of irregularity scheme inside WLAN

摘要

The rokarueria network where OFDM bureau and DSSS/CCK bureau coexist is offered. Between contention free periods, it operates under the centralized control functional rule where both bureau is decided with IEEE802.11 standard. Both bureau, when polling being done from access point, transmits the data. Contention free period, OFDM bureau operates under decentralized control function, DSSS/CCK bureau waits for the fact that polling it is done from access point and begins communication, it possesses sub contention period.
