Abstract

A wireless and cordless telephone node system. The system includes a node with a wireless transceiver that communicates wireless signals with a wireless network and a cordless transceiver that communicates cordless signals with multiple cordless terminal units. A switch routes call between the wireless network and the multiple cordless terminals. A variety of cordless terminals are provided that emulate conventional corded telephones, cordless telephones and wireless telephones. The wireless node is designed for both fixed and portable operation.

Claims

a second processor adapted to convert plural cordless audio signals, corresponding to the plural cordless telephone terminal units, and cordless control signals from said cordless telephone signals;

a switch coupled to connect said wireless audio signals and said plural cordless audio signals, and

a controller coupled to cause said switch to connect any two of said wireless audio signals and said plural cordless audio signals in response to said wireless control signals or said cordless control signals.

2. The system of claim 1 wherein said wireless transceiver operates in compliance with a promulgated wireless network signaling protocol.

3. The system of claim 2 wherein said protocol is selected form one of GSM, T-Mobile, CDMA, TDMA, or AMPS.

4. The system of claim 1 wherein said first cordless transceiver operates in one of the 900 MHz cordless band, the 1.8 GHz cordless band, the 2.4 GHz cordless band, or the 5.8 GHz band in accordance with an analog standard, the PHS, DECT, or DSS protocols.

5. The system of claims 1 further comprising a portable housing.

6. The system of claim 5 further comprising a charging circuit having a charging output.

7. The system of claim 6 wherein said housing has a charging cradle formed thereon for engaging a cordless terminal unit, and wherein said charging output is aligned to couple to corresponding charging contacts on the cordless terminal unit when engaged with said charging cradle.

8. The system of claim 7 wherein said charging circuit further comprising a battery coupled to power the node and coupled to said charging output.

9. The system of claim 1 further comprising a mounting structure adapted to support said housing from a vertical surface.

10. The system of claim 1 further comprising a clock and clock display.

11. The system of claim 1 further comprising a broadcast radio receiver having a radio audio output and a radio user interface.

12. The system of claim 11 wherein said radio audio output is coupled to said switch, and wherein said controller is operable to cause said switch to connect said radio audio to said wireless transceiver or said cordless transceiver.

13. The system of claim 1 further comprising at least a first cordless terminal unit, comprising:

a second cordless transceiver adapted to communicate cordless signals, including audio signals and control signals, with said first cordless transceiver;

an audio circuit operable to couple audio signals between said second cordless transceiver and a speaker and microphone;

a battery coupled to power the cordless terminal unit;

a user interface adapted to receive user inputs, wherein said user inputs are coupled to said second cordless transceiver as cordless control signals, and

an enclosure that supports said battery, said second cordless transceiver, and said audio circuit.

14. The system of claim 13 wherein said cordless terminal unit further comprises:

an ear support structure fixed to said enclosure for supporting the cordless terminal on a user'"'"'s ear, and

a microphone support structure fixed to said enclosure for locating said microphone in receptive proximity to a user'"'"'s mouth while said ear support structure is engaged with the user'"'"'s ear.

15. The system of claim 13 wherein said enclosure further comprises battery charging contacts disposed on the exterior thereof, said charging contacts coupled to said battery for charging thereof, said cordless terminal further comprising:

a charging cradle adapted to receive said cordless terminal unit;

a charging circuit disposed within said charging cradle, and

charging terminals disposed on the exterior of said charging cradle and coupled to said charging circuit, said charging terminal aligned to engage said battery charging contacts when said cordless terminal unit is engaged with said charging cradle.

16. The system of claim 13 further comprising:

a handset having said microphone and said speaker disposed therein, and
