Japanese Patent JPH06508252
Kind Code:
A
Abstract:
In a wireless frequency and time division multiple access (FD/TDMA) communications system having time-slotted communications channels, there is provided a method of and apparatus for hopping wireless communications. It comprises sequencing slot assignments and sequencing frequency assignments, such that a multiplicity of frequencies are thereby usable at each site of a cellular FD/TDMA system without regard to local partitioning among surrounding uses thereof. The effect would be to probablistically reduce the interference, not only by the number of hopping frequencies, but by a factor of the number of time slots per frame.
