Abstract

A method and system provides for removing a number of channels from a larger pool of channels. The channels are assigned in ways to provide subscribers with both voice and digital data service. The system is designed to support POTS ISDN, and direct data service in a point to multipoint configuration. Channel concatenation provides a multiplicity of channels. The system utilizes frequency division duplex (FDD) operation so as to double capacity.

Claims

1. A wireless telecommunication system to allow individual subscribers in an area of telecommunications service access to a telecommunications network comprising:

at least one subscriber interface,

the at least one subscriber interface connected to one or more items of customer premise equipment, the customer premise equipment capable of transmitting and/or receiving voice and/or data signals;

the at least one subscriber interface having a modulator for modulating voice and/or data signals from the customer premise equipment into a form suitable for transmission over a wireless communication channel;

the at least one subscriber interface having a demodulator for demodulating a signal received over a wireless communication channel into a voice or data signal;

a base station interface,

the base station interface connecting the wireless telecommunication system to the telecommunication network;

the base station interface having a modulator for modulating voice and/or data information from the telecommunication network into a form suitable for transmission over a wireless communication channel;

the base station interface having a demodulator for demodulating a signal received over a wireless communication channel into a form suitable for transmission over the telecommunication network;

a plurality of wireless communication channels, a first sub-pool of the wireless communication channels being used for communication between the base station interface and the plurality of subscriber interfaces, a second sub-pool of wireless communication channels being used for communication between the base station interface and at least one enhanced subscriber interface; and

at least one enhanced subscriber interface including an enhanced radio unit;

the enhanced subscriber interface being capable of handling the second sub-pool of communication channels;

the enhanced subscriber interface further being capable of handling a plurality of active customer premise equipment.

2. The system of claim 1, wherein the enhanced suscriber interface handles voice service.

3. The system of claim 1, wherein the enhanced suscriber interface handles data service.

4. The system of claim 1, wherein the enhanced suscriber interface handles multimedia service.

5. The system of claim 1, wherein the enhanced suscriber interface handles video service.

6. The system of claim 1, wherein the enhanced suscriber interface handles concatenation of a number of channels to form a high rate hyperchannel.

7. The system of claim 1, wherein the enhanced suscriber interface handles voice, data, multimedia or video service simultaneously.

8. The system of claim 1, wherein the enhanced suscriber interface increases or decreases the number channels in the second sub-pool without interruption of service.

9. The system of claim 1, wherein the number of channels in the second sub-pool is chosen so as to provide a specified quality of service as measured by a ratio of a number of blocked subscriber communications versus a number of subscriber communications attempted and wherein the enhanced subscriber interface handles which attempted subscriber communication is to be blocked.

10. The system of claim 1, wherein the number of channels in the second sub-pool can be changed dynamically depending upon the channel usage and/or environmental conditions and wherein the enhanced subscriber interface determines when the number of channels in the second sub-pool should be changed.

11. The system of claim 1, wherein the enhanced suscriber interface services a high occupancy residential or business unit.
