Application of TDM/TDMA in Point to Multi-point WLAN

The TDMA method has many advantages such as occupying narrower frequency band,no near-far effect,easiness for increasing capacity and simpleness for realization,as a result it is applied extensively.In order to meet the practical need,this paper presents an application scheme of wireless network,which is point to multi-point network and has its own center.The actual frame structure is given.Frame synchronization technology and the dynamic latency adjustment technology are introduced in detail.Considering the MAC protocols based on competition may often limit the network performance,we allocate channels dynamically using the way of token-polling.
