Wireless network system and communication method employing both contention mode and contention-free mode

摘要: A network communication system is provided whereby stations can obtain priority for data transmission to communicate directly with each other in a contention-free mode period independently of polling operation the control station. The station emits series beacons at equal intervals initiate completion predetermined number beacons. During maximum initiated, allowing transmission, by time-slots imaginarily from start throughout period. conducts call-connection procedure order given set time-slots.
