Filed:

Jul 21, 2006

Appl. No.:

11/490923

Inventors:

Eric G. Parker - Plantation FL, US
Michael A. Criger - Lake Worth FL, US
Gregory S. Smith - Ocean Ridge FL, US

International Classification:

H04Q 7/20

US Classification:

455423

Abstract:

A wireless communication () device for placing calls within a wireless communication system () on a plurality of channels is provided. The wireless communication unit () includes a transceiver () for transmitting and receiving radio frequency (RF) signals on the plurality of channels, a signal detector (), a network scanner () and a controller (). The signal detector () detects whether a call on one of the plurality of channels has been dropped (). The network scanner () controls which of the plurality of channels the transceiver receives signals on and which of the plurality of channels the transceiver transmits signals on. The controller () automatically increases a scan rate () of the network scanner () in response to the signal detector () determining that the call has been dropped ().

Abstract:

A technique is used by a squelch circuit (200) that generates a fast squelch. The technique involves generating a noise signal (211) from a demodulated signal (105), generating a squelch check request (405) of one of two types, performing a release (410) of a reset control (107) in response to the squelch check request, generating an integrated noise signal (106) having essentially no decay rate from the noise signal starting at the release of the reset control, generating a result of a comparison (815, 860) of the integrated noise signal to one of two values corresponding to the one of two types of squelch check requests at an expiration of a predetermined delay started at the release of the reset control, and controlling a muting (845, 870) of a speaker (128) in response to the comparison.
