329.0. "Technical roaming question" by ATYISA::POITEVIN () Tue Feb 11 1997 03:50

    
    I have a technical question about the roaming in FH.
    If you have 2 APs in roaming mode and a PC, when the PC change cell
    which decide the change, the PC or the AP (the power of the signal ...)
    and how the PC can see 2 differents frequencies at the same time,
    (because each AP use differents hopping sequence).
    
    Thanks,
    
    Thierry.

329.1The client initiales the handover.IROCZ::SCHWARTZTue Feb 11 1997 13:229
    Hi Thierry,
    
    The client continuously looks at the signal quality of recieved
    packets.  When the quality drops, the client starts to search for
    another AP.  The client searches all the channels till it finds one of a better
    quality and then starts the handover request, which gets negotiated
    between the receiving AP and the old AP.
