MITIGATING TRANSMISSION INTERFERENCE BETWEEN DIGITAL RADIO AND BROADBAND COMMUNICATION DEVICES

摘要

A broadband device (105) can detect a proximate narrowband transmission (152) from a narrowband communication device (145). The narrowband transmission (152) can be in close enough proximity (155) to at least one bearer channel of the broadband device (105) to result in interference on the narrowband reception (152) when the broadband device (105) is transmitting and the narrowband communication device (145) is concurrently receiving. Responsive to the detecting, the broadband device (105) can gate a broadband transmission (142) to ensure the broadband transmission (142) does not interfere with the proximate narrowband reception (152). In absence of detecting the narrowband transmission (152), the broadband transmission (142) from the broadband device (105) would not be gated.

1. A method for mitigating radio frequency interference comprising:
detecting, at a broadband device, a narrowband transmission from a narrowband communication device, wherein the narrowband transmission is in close enough proximity to at least one bearer channel of the broadband device to result in interference on the narrowband reception when the broadband device is transmitting and the narrowband communication device is receiving concurrently, and further wherein the narrowband communication device and the broadband device are separate devices; responsive to the detecting, determining, by the broadband device, that the narrowband communication device is proximate to the broadband device; and responsive to determining that the narrowband communication device is proximate to the broadband device, gating, by the broadband device, a broadband transmission to ensure that the broadband transmission does not interfere with the proximate narrowband reception, wherein in absence of detecting the narrowband transmission the broadband transmission from the broadband device would not be gated.
