Abstract

A client computer system is suitable for connection to a data processing network having a controlling system. The controlling system is operable to issue a wake-up request to the client computer system. The wake-up request is issued by means of a wireless connection between the controlling system and the client computer system. The client computer system, on receipt of the wake-up request, powers itself on so as to allow normal operation of the client computer system.

Claims

1. A client computer system, suitable for connection to a data processing network having a controlling system, the controlling system being operable to issue a wake-up request to the client computer system, the wake-up request being issued by means of a wireless connection between the controlling system and the client computer system, the client computer system, on receipt of the wake-up request, powering on so as to allow normal operation of the client computer system.

2. A client computer system as claimed in claim 1, wherein the wireless connection between the controlling system and the client computer system is a satellite data link.

3. A client computer system as claimed in claim 1, wherein the wireless connection between the controlling system and the client computer system is a Digital Enhanced Cordless Telecommunications (DECT) link.

4. A client computer system as claimed in claim 3, wherein the client computer system also provides a voice link simultaneously with a data link, the voice link and the data link using a single DECT link.

5. A client computer system as claimed in claim 1, wherein the wake-up request is a Wake-on-LAN frame and the client computer system includes a network interface card operable, on receipt of a Wake-on-LAN frame, to power-on the client computer system.

6. A client computer system as claimed in claim 1, wherein the controlling system is operable to issue a request to the client computer system to cease functioning, the client system comprising means for disabling the client computer system from further operation.

7. A wireless network adapter for use in a client computer system, suitable for connection to a data processing network having a controlling system, the controlling system being operable to issue a wake-up request to the client computer system, the wake-up request being issued by means of a wireless connection between the controlling system and the wireless network adapter of the client computer system, the client computer system, on receipt of the wake-up request, powering on so as to allow normal operation of the client computer system.

8. A wireless network adapter as claimed in claim 7, wherein the wireless connection between the controlling system and the wireless network adapter is a satellite data link.

9. A wireless network adapter as claimed in claim 7, wherein the wireless connection between the controlling system and the wireless network adapter is a Digital Enhanced Cordless Telecommunications (DECT) link.

10. A wireless network adapter as claimed in claim 9, wherein the wireless network adapter also provides a voice link simultaneously with a data link, the voice link and the data link using a single DECT link.

11. A wireless network adapter as claimed in claim 7, wherein the wake-up request is a Wake-on-LAN frame and the wireless network adapter is operable, on receipt of a Wake-on-LAN frame, to power-on the client computer system.

12. A wireless network adapter as claimed in claim 7, wherein the controlling system is operable to issue a request to the wireless network adapter to cease the client computer system to cease functioning, the client system comprising means for disabling the client computer system from further operation.
