Dual-radio communication apparatus, and an operating method thereof
First Claim
1. A dual-radio communication apparatus comprising:
- a first radio device for use in a first frequency band;
a second radio device for use in a second frequency band, proximate to the first frequency band;
a controller coupled to the first and second radio devices;
wherein the first radio device has a first operating mode employing a first frequency range, and a second operating mode employing a second frequency range, the second frequency range being smaller than the first frequency range; and
wherein the controller is adapted to set the first radio device in its second operating mode, when the second radio device is in operation, and otherwise set the first radio device in its first operating mode.

Abstract
A dual-radio communication apparatus has a first radio device, such as a Bluetooth radio, for use in a first frequency band, and a second radio device, such as a Globalstar satellite radio, for use in a second frequency band, which is proximate to the first frequency band. The communication apparatus also has a controller coupled to the first and second radio devices. The first radio device may comprise a frequency-hopping spread-spectrum transmitter. Moreover, the first radio device has a first operating mode employing a first frequency range. The first radio device also has a second operating mode employing a second frequency range, which is smaller than the first frequency range. The controller is adapted to set the first radio device in its second operating mode, when the second radio device is in operation, and otherwise set the first radio device in its first operating mode.

7. A method of operating a dual-radio communication apparatus comprising:
-
a first radio device for use in a first frequency band; a second radio device for use in a second frequency band, proximate to the first frequency band, the method comprising the steps of; a) determining whether the second radio device is in operation; b) for the first radio device, using a first frequency range, if the answer in step a) is in the negative; and c) for the first radio device, using a second frequency range, the second frequency range being smaller than the first frequency range, if the answer in step a) is in the affirmative. - View Dependent Claims (8)
