摘要： A method and apparatus of implementing protocol state machines that conserve energy on energy conscious devices is disclosed. Under this method, most of the energy consuming protocol state machine context invocations or operations are aggregated in time and are scheduled at regular intervals. Such an aggregation leads to many contexts executing concurrently in a burst prior to entering a dormant state. Thus, resource usage can reach a predictable rate pattern of idle and active cycles. With such a pattern, it is possible to take advantage of the energy saving features of processors by downshifting the processor clock speed and use of other resources such as peripherals and buses. The intervals are configured to achieve a tradeoff between timely execution and energy consumption. The aggregation operates across two dimensions, namely, multiple instances of a protocol state machine and multiple layers of protocols in a layered architecture.

摘要： A system and method for adjusting quality of service in a communication system improves an allocation of resources in a communications environment with shared resources among multiple communicating stations by adjusting quality of service levels based on characteristics of the communicating stations. In a disclosed embodiment, a base station (130) communicates with one or more remote stations (110a, 110b). Quality of service levels for communications between the base station and a remote station 110 are adjusted based on a characteristic of the remote station. In this way, a lower quality remote station can be allocated a lower quality of service level than that allocated to a higher quality remote station, thereby preventing an inefficient allocation of shared resources and improving overall system performance.

摘要： A dual channel redundant wireless network link formed by the Redundant Fixed Wireless Network Link device 10 of the present invention provides a very high reliable network element for mission critical wireless network application. Redundant Fixed Wireless Link device (10) with two wireless networking radio channel (11,12) turned on simultaneously, and running networking service feature is working as Service Equipment (SE). Both wireless networking radio channel (11,12) of the SE have the same directional wireless network coverage area. The two wireless networking radio channels (11,12) are separated by cross polarization of antenna at same radio frequency, or different radio frequency character. One Redundant Fixed Wireless Link device (10) with one of its two wireless networking radio channel (11,12) turned on and communicating with said SE, and loaded with networking client feature is acting as Client Equipment (CE). The link quality monitor feature of the CE is monitoring the communication link between the SE and CE. When the current link quality is low or the link is down, the CE automatically switches on the alternate wireless networking radio channel (11,12) to maintain the network communication between the SE and CE. One SE may communicate with plurality of CE in the same wireless network coverage area.

摘要： An RF switch 12 is connected to a receiving unit 2 at a reception timing. An RF signal received by an antenna 11 is inputted to an amplifying unit 5 via an isolator 3 and an RF filter 4. The RF signal is subjected to automatic gain amplification and is inputted to a demodulating unit 6. An RSSI 61 detects the level of a reception signal. When the detection value is over a threshold, a demodulator 62 controls the RF switch so as to change the switch to a transmitting unit 7 which does not output and send the signal. Consequently, the input of the receiving unit is largely attenuated. The isolator maintains the matching of the input impedance of the amplifying unit and ensures the low-noise property and stability, irrespective of a switching state of the change-over switch.

摘要： A directional coupler for a modem has a high common mode noise rejection characteristic with low transmit signal leakage, and reduced distortion of components mixed with a received signal. A primary filter network is connected to a communications circuit. The primary filter network has an output connected to an input of an amplifier. A feedback network is connected between the input and output of the amplifier. The primary filter network, the amplifier and the feedback network are arranged to provide a virtual ground at the input of the amplifier, and a filter characteristic which attenuates frequencies in the transmit signal band. The advantage is reduced component count while providing excellent transmit signal rejection and reducing received signal distortion.

摘要： A high-frequency module includes a switching circuit having a phase-shift circuit. The phase-shift circuit matches only PCS/DCS reception signals so as to be passed therethrough by setting a control-voltage input terminal to a Low level when receiving PCS/DCS signals, and attenuates PCS/DCS transmission signals to the PCS/DCS reception circuit side by setting the control-voltage input terminal to a Hi level when transmitting PCS/DCS signals. Also, another phase-shift circuit, which further attenuates the PCS transmission signal when transmitting the PCS signal, is provided in the DCS Rx terminal side of the phase-shift circuit.
