Self-monitoring radio network
First Claim
1. A method of identifying nonfunctional two-way radios from among a known group of two-way radios expected to be operating within a region, the method comprising:
- for each of the two-way radios expected to be operating within the region, establishing a corresponding window of time;
for each of the established windows of time, awaiting a transmission from the corresponding radio;
if, for a particular radio, no transmission is detected within its corresponding window of time, recording the absence of the transmission; and
if, for a particular radio, the number of times absence of transmission has been recorded exceeds a threshold, identifying the particular radio as nonfunctional.

Abstract
A scheme of identifying nonfunctional two-way radios from among a known group of two-way radios expected to be operating within a region may include establishing a corresponding window of time for each of the two-way radios expected to be operating within the region. For each of the established windows of time, a transmission from the corresponding radio is awaited. If, for a particular radio, no transmission is detected within its corresponding window of time, the absence of the transmission is recorded. Finally, if, for a particular radio, the number of times absence of transmission has been recorded exceeds a threshold, the particular radio is identified as nonfunctional.

14. A two-way radio improved so as to render its operability observable, the two-way radio comprising:
-
an antenna for receiving and broadcasting transmissions;
a transceiver unit coupled to the antenna for modulating a carrier signal with a signal to be transmitted and for recovering a baseband signal from a received transmission;
a microprocessor coupled to the transceiver unit, the microprocessor programmed to command a broadcast of a transmission containing a code identifying the radio, at a designated point in time; and
wherein, prior to the broadcast of the transmission containing the identification code, a transmission protocol governing subsequent transmissions is known by the radio. - View Dependent Claims (15, 16, 17, 18)

19. A wireless intercom system comprising:
-
a first two-way radio fashioned as a headset;
a second two-way radio fashioned as a headset; and
a repeater unit;
wherein transmissions from the first and second two-way radio occur upon a first carrier frequency;
wherein the first and second two-way radios receive transmissions carried upon a second carrier frequency;
wherein the repeater unit receives transmission carried upon the first carrier frequency, and broadcasts transmissions upon the second carrier frequency, thereby enabling the first and second two-way radios to communicate;
wherein the repeater unit establishes a first window of time corresponding to the first radio and a second window of time corresponding to the second radio;
wherein, the repeater unit awaits a transmission from the first radio during the first window of time, and awaits a transmission from the second radio during the second window of time;
wherein, the repeater unit records absence of transmission from the first radio, if no transmission is received from the first radio during the first window of time;
wherein, the repeater unit records absence of transmission from the second radio, if no transmission is received from the second radio during the second window of time;
wherein, the repeater unit identifies the first radio as nonfunctional if the number of times absence of transmission by the first radio has been recorded exceeds a threshold; and
wherein, the repeater unit identifies the second radio as nonfunctional if the number of times absence of transmission by the second radio has been recorded exceeds a threshold. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
