Method for overlay of narrowband and wideband communication systems |
摘要 |
The present invention relates to methods and systems for wireless communication wherein a plurality of narrowband carrier frequencies is overlaid with at least one wideband carrier frequency. In particular, the present invention relates to maintaining radio communication on the narrowband carrier frequencies closest to the edge of the bandwidth of the wideband carrier frequency in order to reduce system interference. This is accomplished by using frequency hopping to preferentially switch radio communication to narrowband carrier frequencies closest to the edge of the bandwidth of the wideband carrier frequency. Thus, the present invention discloses systems and methods which allow several communication devices to occupy the same frequency spectrum while maintaining interference at acceptable levels.
