White Paper - WiTDM Vs. 802.11
Source: Formosa Wireless Systems
WiTDM is one kind of TDMA technology, and a transmission protocol suitable for outdoor equipments with Point to Point and Point to Multi-Point transmission in long distance. Being different from 802.11 CSMA/CA, the maximum transmission efficiency of WiTDM can be up to 150% of CSMA/CA 802.11. In the outdoor environment, WiTDM won't have the problem of hidden node which comes up to 802.11 often, and overall network band won't be seriously reduced because of the hidden node. In 802.11 network, a remote transmission device with bad transmitting quality will be influenced seriously, while WiTDM won't have this kind of NEAR-FAR problem.
