1. A method for communication comprising:
- assigning a control channel common to a first device and a second device;
scanning a first set of channels by the first device;
scanning a second set of channels by the second device;
exchanging control information over the control channel between the first device and the second device, the control information being based upon the scanning of the first device and the scanning of the second device;
from the control information, finding a data channel available to both the first device and the second device for data communications between the first device and the second device by selecting an optimal data channel for use in communicating, the optimal data channel having optimal characteristics satisfying a desired intersymbol interference; and
communicating data over the data channel between the first device and the second device.

23. A communication device comprising a processor configured to:
-
assign a control channel common to the communication device and a further device; scan a first set of channels; exchange control information with the further device over the control channel, the control information being based upon the scan and a scanning by the further device of a second set of channels; from the control information, find a data channel available to both the communication device and the further device for data communications between the communication device and the further device by selecting an optimal data channel for use in communicating, the optimal data channel having optimal characteristics satisfying a desired intersymbol interference; and communicate data over the data channel between the communication device and the further device. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
