Abstract:
A radiotelephone comprises both a Mobile Station Modem, a Bluetooth radio frequency unit, an interface between them and other supporting hardware/software, allowing utilization by a subscriber to implement a truly Universal remote control device An embodiment of the present invention includes an interface for connecting a mobile station modem to a radio frequency unit equipped for transmitting and receiving a frequency hopped signal, a serial bus interface operably connected between the Mobile Station Modem and the Bluetooth radio frequency unit including a plurality of bi-directional serial data connections. The preferred embodiment further includes a bi-directional serial data connection for transmitting data for transmission connected between the Mobile Station Modem and the Bluetooth radio frequency unit and a synchronous detector and transmit enabling serial data connection for receiving an enabling indication valid data at said radio frequency unit from the Mobile Station Modem.
Abstract:
A base station and receiver system for use in a base station which achieves enhanced dependability by logically separating the diversity reception paths into different failure paths. In one embodiment, the receiver system includes a first diversity reception path for receiving a first radio signal and a second diversity reception path for receiving a second radio signal. The first and second radio signals may be amplitude and phase shifted versions of the same information signal according to well known principles of diversity reception. At least one demodulator diversity combines the first and second radio signals and demodulates the diversity combined first and second radio signals. Additionally, the first and second diversity paths are logically separated into different failure paths.
Abstract:
A portable electronic device or wireless communication device (WCD) has at least one provision for optional equipment or user services. Options are provided for a user in a menu selection for selection by the consumer of the options. The user selects the options for the particular WCD and the options are installed on delivery or prior to delivery, thereby providing the user with an initial selection of the options.
Abstract:
A wireless telephone (102) includes a telephone transceiver (104), GPS receiver (106), and Bluetooth transceiver (108). The telephone antenna (110) is external, and the Bluetooth antenna (120) is internal. The GPS receiver (106) may be driven by its own internal antenna (326), or via a signal separator (116), (216), by either of the other antennas (110), (120).
