Abstract: A base station comprises a radio port cluster and a switch/router. Instead of passively following the order from a client terminal, the WiFi base station plays the major role in a hand-over process. The base station will monitor the client terminal signal strength and negotiate with other base stations for the client terminal connection including authentication and authorization. When the client terminal's signal strength is changing, the base station will send out a request to other base stations to report signal strength and trend of this particular client terminal. Based on reported signal strength and trend, a determination is made as to which of the other base stations should take over the servicing of the client terminal. The authentication is then forwarded to this base station.

Abstract: A sampling timing recovering circuit free from being troubled by a frequency error is provided. Such recovering circuit includes a phase locking circuit having a local frequency for processing an incoming signal having a phase, a specific parameter and an input symbol rate and for locking the phase of the incoming signal, and a frequency locking circuit electrically connected to the phase locking circuit for locking the input symbol rate of the incoming signal to enable the phase locking circuit to desiredly process the incoming signal. A method to this effect is also provided and includes the steps of a) processing an incoming signal having a phase, a specific parameter and an input symbol rate to have the phase lockable, b) locking the phase of the incoming signal, and c) locking the input symbol rate of the incoming signal to enable the incoming signal to be predeterminedly processed.
