The wireless LAN comprises several access points and stations which establish wireless communication connections with the access points. The stations can switch the current access window by scanning. The method characterizes in that including following steps: giving the switching window an initial value through the stations; the stations judge if there is another access point of which the signal quality is greater than that of the current access window through scanning wireless channels; if so, further judge if the stations are in a frequently handoff status, if so, the handoff judging result is not allowed to switch window; if not, the handoff judging result is allowed to switch window. The present invention can adaptively adjust the stations' switch windows according to the stations' handoff status and frequently handoff status. On one hand, the invention avoids the occurring of frequently handoff by changing the handoff conditions of the stations, increasing the access efficiency of the stations which is in the handoff status and in a wireless LAN environment, while maintaining the sensitivity of the stations which is in the handoff status, ensuring the quality of the wireless links between the stations and the access points.

    摘要: An apparatus comprising a programmable frequency device adapted to generate a reference clock selected from a set of distinct frequency clocks, wherein the programmable frequency device is further adapted to maintain the same temporal relationship of the triggering edges of the reference clock when switching between the distinct frequency clocks. The apparatus further comprises a phase locked loop (PLL), such as a digital PLL (DPLL), that uses the selected reference clock to establish a predetermined phase relationship between an input signal and an output signal. By maintaining substantially the same temporal relationship of the reference clock when switching between distinct frequency clocks, the continual and effective operation of the phase locked loop (PLL) is not significantly disturbed while changing the reference clock. This may be used to control the power consumption of the apparatus.

    摘要: A circuit receives a first signal (for example, a baseband signal) and mixes it with a local oscillator (LO) signal, and outputs a second signal (for example, an RFOUT signal). The circuit includes multiple identical Mixer and Frequency Divider Pair (MFDP) circuits. Each MFDP can be enabled separately. Each MFDP includes a mixer and a frequency divider that provides the mixer with a local version of the LO signal. The MFDP outputs are coupled together so that the output power of the second signal (RFOUT) is the combined output powers of the various MFDPs. By controlling the number of enabled MFDPs, the output power of the second signal is controlled. Because the MFDPs all have identical layouts, accuracy of output power step size is improved. Because LO signal power within the circuit automatically changes in proportion to the number of enabled MFDPs, local oscillator leakage problems are avoided.
