Abstract

A method for setting up and operating a multiple communication link in a wireless communication apparatus, which includes a first wireless transceiver and a second wireless transceiver, includes setting up a first communication link according to an IEEE standard 802.15.1 using the first wireless transceiver. The method also includes setting up a second communication link according to an IEEE standard 802.11 using the second wireless transceiver, and setting up a third communication link according to an IEEE standard 802.15.1 using the first wireless transceiver, on a channel of the second communication link. Moreover, the method includes simultaneously operating the first communication link, the second communication link and the third communication link, wherein the second communication link and the third communication link are both simultaneously operated on the same channel of the second communication link.

Claims

1. A method for setting up and operating a multiple communication link in a wireless communication apparatus that includes a first wireless transceiver and a second wireless transceiver, the method comprising the acts of:

setting up a first communication link according to an IEEE standard 802.15.1 using the first wireless transceiver;

setting up a second communication link according to an IEEE standard 802.11 using the second wireless transceiver;

setting up a third communication link according to an IEEE standard 802.15.1 using the first wireless transceiver, on a channel of the second communication link;

operating simultaneously the first communication link, the second communication link and the third communication link, wherein the second communication link and the third communication link are both simultaneously operated on said channel of the second communication link;

splitting a transmission capacity of said channel of the second communication link, on which both the second communication link and the third communication link are operated simultaneously, into a first sub-channel with a first partial capacity and into a second sub-channel with a second partial capacity;

assigning the first sub-channel to the second communication link; and

assigning the second sub-channel to the third communication link.

2. The method according to claim 1, wherein

the first communication link is operated according to a Bluetooth standard 2.1 or less.

3. The method according to claim 2, wherein

the third communication link is operated on an additional high speed channel on a wireless local area network.

4. The method according to claim 1, wherein

the third communication link is operated according to a Bluetooth standard that supports establishing an additional wireless local area network transmission channel.

5. The method according to claim 2, wherein

the third communication link is operated according to a Bluetooth standard that supports establishing an additional wireless local area network transmission channel.

6. The method according to claim 1, wherein

the third communication link is operated on an additional high speed channel on a wireless local area network.

7. A wireless communication apparatus, comprising:

a first wireless transceiver; and

a second wireless transceiver, wherein

the communication apparatus is configured to;

set up a first communication link according to an IEEE standard 802.15.1 using the first wireless transceiver;

set up a second communication link according to an IEEE standard 802.11 using the second wireless transceiver;

set up a third communication link according to an IEEE standard 802.15.1 using the first wireless transceiver, on a channel of the second communication link;

operate simultaneously the first communication link, the second communication link and the third communication link, wherein the second communication link and the third communication link are both simultaneously operated on said channel of the second communication link;

split a transmission capacity of said channel of the second communication link, on which both the second communication link and the third communication link are operated simultaneously, into a first sub-channel with a first partial capacity and into a second sub-channel with a second partial capacity;

assign the first sub-channel to the second communication link; and

assign the second sub-channel to the third communication link.

8. The wireless communication apparatus according to claim 7, wherein the first wireless transceiver is operated according to an IEEE standard 802.15.1.

9. The wireless communication apparatus according to claim 8, wherein the first wireless transceiver operated according to a Bluetooth standard that supports establishing an additional wireless local area network transmission channel.

10. The wireless communication apparatus according to claim 7, wherein the second wireless transceiver is operated according to an IEEE standard 802.11.

11. A motor vehicle, comprising:

a wireless communication apparatus, wherein the wireless communication apparatus includes a first wireless transceiver and a second wireless transceiver, wherein the communication apparatus is configured to;

set up a first communication link according to an IEEE standard 802.15.1 using the first wireless transceiver;

set up a second communication link according to an IEEE standard 802.11 using the second wireless transceiver;

set up a third communication link according to an IEEE standard 802.15.1 using the first wireless transceiver, on a channel of the second communication link;

operate simultaneously the first communication link, the second communication link and the third communication link, wherein the second communication link and the third communication link are both simultaneously operated on said channel of the second communication link;

split a transmission capacity of said channel of the second communication link, on which both the second communication link and the third communication link are operated simultaneously, into a first sub-channel with a first partial capacity and into a second sub-channel with a second partial capacity;

assign the first sub-channel to the second communication link; and

assign the second sub-channel to the third communication link.
