Abstract:
1. A method for allocating frequencies in a frequency hopping spread spectrum communications link over which data is transmitted from a first transceiver to a second transceiver, the method comprising the steps of: selecting a hop sequence that is stored in each of the first and second transceivers comprised of a plurality of frequency channels over which the first and second transceivers communicate, the selecting the hop sequence comprising: identifying a frequency channel in the hop sequence as being unsatisfactory; performing a frequency channel substitution by replacing the unsatisfactory frequency with an alternative frequency, in the hop sequence of the second transceiver; transmitting an unacknowledged substitution command a first time by the second transceiver requesting that the first transceiver perform the frequency channel substitution in its hop sequence; and transmitting the unacknowledged substitution command a second time by the second transceiver requesting that the first transceiver perform the frequency channel substitution in its hop sequence.
