Intercom module for a wireless system
First Claim
1. An apparatus comprising:
- a microphone;
an audio amplifier coupled to the microphone;
a speaker coupled to the audio amplifier and adapted for generating a sound audible at about a room-sized distance from the speaker;
a processor coupled to the audio amplifier;
a set of executable instructions accessible to the processor, the set of instructions adapted for causing the processor to recognize a voice received by the microphone and to generate a digital command in response thereto; and
a spread spectrum frequency hopping transceiver coupled to the processor and adapted for wirelessly communicating digital data.

Abstract
A wireless intercom system having a BLUETOOTH® enabled transceiver. Voice recognition programming allows the user to select or control the operation of a particular intercom unit. User operable selections or controls allow specifying the target unit for communicating, selecting a threshold level for a squelch circuit, engaging a monitor function of the local unit or a remote unit, transmitting a page command, or other user operable function. In one embodiment, the intercom is adapted for wall mounting using a standard electrical box listed by Underwriters Laboratories Inc. In one embodiment, the transceiver is compatible with both a short range communication protocol and a long range communication protocol. In one embodiment, a compatible wireless repeater extends the range of the intercom by coupling with a long range communication network such as a cellular telephone network, pager network, or Internet.

19. A method of manufacturing comprising:
-
coupling a microphone and a speaker to an audio amplifier having sufficient power to operate the speaker at a level such that a sound produced by the speaker is audible throughout a room;
coupling a processor to the audio amplifier;
coupling a spread spectrum frequency hopping transceiver to the processor;
coupling a power source connector to the audio amplifier, processor and transceiver; and
providing instructions accessible to the processor and adapted for causing the processor to instruct the transmitter to wirelessly transmit digital data based on local audio proximate the microphone and adapted for wirelessly receiving digital data based on remote audio and adapted for recognizing a voice received by the microphone and for generating a digital command in response thereto.

23. A method of communicating comprising:
-
transmitting a request to receive an identification number of a compatible transceiver within a predetermined range using a first spread spectrum frequency hopping transceiver;
receiving the identification number for the compatible transceiver;
receiving local audio;
digitizing the local audio having a sound pressure level above a predetermined threshold;
transmitting the digitized local audio to the compatible transceiver using the first transceiver;
receiving digital data corresponding to remote audio from the compatible transceiver using the first transceiver; and
playing the remote audio on a local speaker such that the sounds are audible within the space of about a room.

28. A method comprising:
-
playing an audible tone upon detecting a switch activation at an entry door associated with a premises having an entry door audio module;
determining occupancy of the premises;
if the premises is vacant, dialing a predetermined telephone number and establishing a first bidirectional communication channel linking the telephone number with the entry door audio module; and
otherwise, establishing a second bidirectional communication channel linking the entry door audio module with a second audio module.
