In general, in one aspect, the disclosure describes a method that includes
selecting an offset between start of communications of a first radio in a
multi-radio platform (MRP) and start of communications of a second radio
in the MRP. Synchronizing clocks of the fist radio and the second radio
to maintain the offset. Determining safe zones within the communications
of the second radio based on configuration of the first radio and the
second radio and the selected offset. The safe zones are locations that
minimize conflicts between receiving operations of the first radio that
are at fixed locations and transmitting operations of the second radio
and transmitting operations of the first radio that are at fixed
locations and receiving operations of the second radio.
