A base station for wireless communication with a plurality of subscriber units, the base station communicating information signals from an originating source to a destination one of said subscriber units at an assigned one of a plurality of frequencies and over an assigned channel, using a repeating time frame, said time frame having a plurality of time slots, said channel being defined by at least one of said time slots in each time frame, said base station comprising:
- a central processing unit capable of assigning a duration of time for the information signals being sent to said one destination subscriber unit, wherein said duration equals the duration of one or more time slots in the same time frame, said central processing unit maintaining a memory of which time slots in each time frame have been assigned and providing said time slot assignment, and therefore said channel assignment, by consulting said memory;
- a multiplexer for multiplexing the information signals onto the assigned channel;
- and
- a transmitter for transmitting the information signals to said destination subscriber unit using the assigned channel.
