Dynamic frame control for TDD based wireless LAN

In a wireless LAN, the radio frequency is an essential resource, but, because this radio frequency is a restricted resource that is shared worldwide, its efficient usage is required. A frame and control structure is proposed to efficiently manage the unbalanced traffic between the uplink and downlink, and the fluctuations of the stations traffic. A prototype for a wireless LAN with a transmission rate of 1.5 Mbits/sec is suggested. It allocates slots to the stations dynamically depending on the traffic, and thus, the idle slots of the idle stations are shared with the heavy traffic stations, so the throughput is increased. As a result of an analysis, it was found that a dynamic transmission speed of between 1 kbits/sec to 1.47 Mbits/sec for each station, with a transmission delay of 0.5 seconds is possible
