    摘要: A mobile station operating in a wireless network system comprising a plurality of base stations is disclosed. A communication unit receives the messages from a first base station of the wireless network system to which the mobile station is currently connected. A signal detection unit detects a first averaged signal strength corresponding to the messages received from the first base station. A processor determines a scan period according to the first averaged signal strength, performing a background scan, at intervals during the scan period, to monitor messages from the plurality of base stations within the wireless network system.

    摘要: An apparatus (and related method) coordinates wireless communication operations for coexisted wireless communication modules. The apparatus includes a packet traffic arbitration (PTA) module coupled between a first wireless communication module and a second wireless communication module, granting the first request requesting for a first wireless communication operation with a first priority in a first time period from the first wireless communication module, receiving a second request requesting for a second wireless communication operation with a second priority from the second wireless communication module when the granted first wireless communication operation is not finished. In operation, the first wireless communication operation interferes with the second wireless communication operation, the PTA module granting the second request and informing the first wireless communication module to take back the granted first request when the second priority is higher than the first priority.

    摘要: A wireless communications module coexisting with a wireless telephony communications module includes a radio frequency (RF) module, a MODEM, a clock generator and distributor and a system control logic. The system control logic issues an external interrupt (EINT) signal to the wireless telephony communications module for activating a clock source via the wireless telephony communications module. When the clock source is activated, the clock generator and distributor receives a reference clock from the activated clock source, converts the reference clock into one or more internal clocks and drives the internal clock or clocks to the RF module and the MODEM for synchronization therebetween.

    摘要: An embodiment of an apparatus for channel assessment is provided, comprising a radio frequency (RF) unit, a baseband unit and a microprocessor control unit (MCU). The baseband unit coupling to the RF unit directs the RF unit to selectively hop into one of a plurality of available channels in a frequency band using a pseudorandom sequence to receive a plurality of packets via the hopped channel. The MCU coupling to the baseband unit accumulates a measure for the hopped channel according to reception results of the packets and marks the hopped channel as a bad channel when the accumulated measure exceeds a predetermined threshold. The measure represents the inaccuracy extent during packet reception via the hopped channel.
