HIPERLAN combines the functions of two infrastructures into the MH. 11 and HIPERLAN, the ad hoc WATM LAN concept is based on the same centralized wireless control framework as the BS-oriented system, but insures that MH designed for the BS-oriented system can also participate in ad hoc networking. Both the BS oriented and ad hoc networks have some drawbacks. In the BS-oriented networks, BS manages all the MHs within the cell area and controls handoff procedures. It plays a very important role for WLAN.

4) The communication continues transmitting directly until the transmission path is broken. 13 Two-hop direct-transmission mode. 3 Handoff – two-hop direct-transmission mode to two-hop direct-transmission mode, one-hop direction-transmission mode or BS-oriented mode If the destination or the intermediate node finds that the strength of the signal is less than a critical value, the handoff procedure is requested and executed at this time. The system will try to find another direct transmission path.
