Abstract: In a wireless communications system, information is communicated over one of a first communications channel having a first redundancy level or a second communications channel having a second redundancy level based on a determination of communications quality for at least one of the channels. In embodiments of the present invention, communications occur over a first channel, e.g., a "standard" channel until a measure of communications quality for that channel, such as bit error rate or frame error rate, meets a predetermined criterion. When the communications quality meets the predetermined criterion, communications shifts to a "robust" high-penetration channel that utilizes substantially the same amount of spectral resource as the first channel but provides significantly increased redundancy. In other embodiments, a terminal, e.g., a cellular radiotelephone or other radio terminal, registers with a wireless communications system via one of a standard broadcast control channel or a high-penetration broadcast control channel, and switches therebetween based upon a determination of communications quality for the standard broadcast control channel. For example, the terminal may switch to the high-penetration broadcast control channel upon failure to acquire the standard broadcast control channel in a disadvantaged reception area.

Abstract: A portable telecommunication apparatus (200) has a user interface (250), a programmable controller (210), a memory (220, 230) coupled to the controller, and an information access program (240), such as a WAP browser, which is stored in the memory and is executable by the controller. The information access program provides access for a user to a global information network, such as Internet, through the user interface and a first wireless communication link. The apparatus also has an external device interface (260, 262, 264) for connecting an external device to the portable telecommunication apparatus over a second communication link. The information access program (240) allows the user to control the external device through the user interface (250), the external device interface (260, 262, 264) and the second communication link.
