Patent ID: 6952571

Claim:
In a computer system comprising a DSP (digital signal processor) and a main processor, a method for periodically measuring signal strength fluctuations of a wireless connection between said computer system and a wireless network, said method comprising the steps of: a) receiving instructions by said DSP from said main processor controlling said measuring of said signal strength fluctuations; b) waking said DSP during periods of transceiving, said waking caused by expiration of a periodic timed interval of low power mode entered by said DSP; c) measuring said signal strength of said wireless connection fluctuations during periods of transceiving, wherein said step c) is performed by said DSP while said main processor remains in said low power mode; d) waking said main processor provided said fluctuation is in excess of an acceptable range; and e) returning said DSP to said low power mode provided said fluctuation of said signal strength is within said acceptable range.
