Abstract

Methods and apparatus for implementing a wireless local loop phone that operates connected to or disconnected from a terminal unit. In one implementation, a phone system includes: a terminal unit comprising: a power source, a handset connection; a handset comprising: an antenna, a modem connected to the antenna, a terminal unit connection, a handset user interface; and a power connection cable connected to the handset connection and to the terminal unit connection; wherein the modem provides an air interface using the antenna, and the air interface provides a wireless local loop, when the handset is connected to the terminal unit through the handset connection and the terminal unit connection, the handset receives power from the power source through the power connection cable.

Claims

1. A phone system, comprising:

a terminal unit comprising;

a power source,

a handset connection;

a handset comprising;

an antenna,

a modem connected to said antenna,

a terminal unit connection,

a handset user interface; and

a power connection cable connected to said handset connection and to said terminal unit connection;

wherein said modem provides an air interface using said antenna, and said air interface provides a wireless local loop, when said handset is connected to said terminal unit through said handset connection and said terminal unit connection, said handset receives power from said power source through said power connection cable.

2. The phone system of claim 1, wherein said handset further comprises

a battery, and when said handset is not connected to said terminal unit through said handset connection and said terminal unit connection, said handset uses said battery for power.

3. The phone system of claim 2, wherein said battery receives power for recharging from said power source.

4. The phone system of claim 1, wherein said air interface provides a cellular phone air interface.

5. The phone system of claim 1, wherein said air interface provides a PCS air interface.

6. The phone system of claim 1, wherein said handset further comprises a handset command interface for processing commands received through said handset user interface.

7. The phone system of claim 6, wherein said handset command interface processes commands received from said terminal unit.

8. The phone system of claim 1, wherein said terminal unit further comprises

a peripheral connection for connecting a peripheral device to said terminal unit.

9. The phone system of claim 8, wherein said peripheral connection is an RJ-11 connection.

10. The phone system of claim 8, wherein said peripheral connection supports connecting a fax machine to said terminal unit.

11. The phone system of claim 8, wherein when said handset is connected to said terminal unit through said handset connection and said terminal unit connection, said handset receives data from said peripheral connection.

12. The phone system of claim 8, wherein when said handset is connected to said terminal unit through said handset connection and said terminal unit connection, said handset sends data to said peripheral connection.

13. The phone system of claim 1, wherein said terminal unit further comprises

a terminal command interface for processing commands received from said handset.

14. The phone system of claim 1, wherein said terminal unit further comprises

a terminal user interface.

15. The phone system of claim 14, wherein said terminal unit further comprises

a terminal command interface for processing commands received through said terminal user interface.

16. The phone system of claim 15, wherein said terminal command interface processes commands received from said handset.

17. A method of operating a wireless local loop phone, the method comprising:

connecting a wireless local loop handset to a terminal unit using a power connection cable;

providing power from said terminal unit to said handset through said power connection cable;

operating said handset using said power from said terminal unit;

disconnecting said handset from said terminal unit; and

operating said handset using power in a battery within said handset;

wherein operating said handset includes sending and receiving signals through a wireless local loop air interface, when said handset is connected to said terminal unit, said handset receiving power from said power from said terminal unit or said battery through said power connection cable.
