Abstract

A communication device includes a stationary phone connectable to a wired telephone network and a removable wireless unit. The stationary phone and wireless unit are provided with a means of a two-way wireless interface. In one embodiment, the wireless unit further includes a built-in multi-functional personal organizer and an optional means of connectivity to a cellular phone network.

Claims

1. A communication device, comprising:

a stationary phone connectable to a wired telephone network; and

a removable wireless unit selectively coupled to the stationary phone using a wireless interface to provide the wireless unit with wireless access to the wired telephone network, the wireless unit being configured for receiving chargeable operating power from the stationary phone.

2. The device of claim 1 wherein the stationary phone and the wireless unit share a common dial in number.

3. The device of claim 1 wherein the stationary phone comprises a means of wireless communicating to the wireless unit, a cradle for receiving the wireless unit, the cradle having a connector for electrical coupling to the wireless unit, a user handset, and at least one dual tone multi-frequency (DTMF) keypad.

4. The device of claim 3 wherein a power supply of the stationary phone recharges a battery of the wireless unit when the wireless unit is positioned in said cradle.

5. The device of claim 1 wherein the wireless unit comprises a means of wireless communicating to the stationary phone, a connector for electrical coupling to the stationary phone, and a display,

6. The device of claim 5 wherein the wireless unit comprises a personal organizer and wherein the display is coupled to the personal organizer.

7. The device of claim 5 wherein the display is a touch-screen display.

8. The device of claim 7 wherein the touch-screen display displays, in an executable format, at least one of a dual tone multi-frequency (DTMF) keypad, an alphanumeric keypad, and programmable keys.

9. The device of claim 1 wherein the stationary phone is compliant with at least one of a public switched telephone network (PSTN) protocol and the Internet Protocol (IP).

10. The device of claim 1 wherein the wireless interface supports communicating of at least one of voice messages, numeric messages, graphical messages, and video messages, and a combination thereof.

11. The device of claim 1 wherein the wireless interface uses at least one communication protocol selected from the group consisting of a base band radio (900 MHz and/or 2.45 GHz) protocol, the 802.11 protocol, the 802.11a protocol, the 802.11b protocol, the 802.11g protocol, and the Bluetooth protocol.

12. The device of claim 1 wherein at least one of the wireless unit and the stationary phone further comprises a means of the Universal Serial Bus (USB) interface to a remote computer or a remote communication device.

13. The device of claim 1 wherein the wireless unit comprises a built-in means for multimedia conferencing.

14. The device of claim 1 wherein the wireless unit is adapted for coupling to an external means for multimedia conferencing.

15. The device of claim 1 wherein at least one of the stationary phone and the wireless unit comprises a speaker and a microphone for hands-free access.

16. The device of claim 1 wherein the wired telephone network is one of a public switched telephone network (PSTN), a telephone network using the Internet Protocol (IP), and a corporate local area network (LAN).

17. The device of claim 1 wherein the wireless unit further comprises a means for selective wireless connectivity to cellular devices in communication with a cellular phone network.

18. A communication device, comprising:

a stationary phone connectable to a wired telephone network; and

a removable wireless unit selectively coupled to the stationary phone using a wireless interface providing the wireless unit with wireless access to one of the wired telephone network and a cellular phone network.

19. The device of claim 18 wherein the wireless unit comprises a means for facilitating switching from the wired telephone network to the cellular phone network when the unit is out of range of the wired telephone network.

20. The device of claim 18 wherein the wireless unit comprises a personal organizer having a display accessible by the wireless unit.

21. The device of claim 20 wherein the personal organizer has built-in scheduling functionality.

22. A wired telephone network supporting at least one communication device, the communication device comprising:

a stationary phone connectable to the network; and

a removable wireless unit having a built-in personal organizer, wherein the stationary phone and the wireless unit are coupled using a wireless interface.

23. The network of claim 22 wherein the stationary phone and the wireless unit have the same dial in number.
