Relaying Communications in a Wireless Sensor System
First Claim
1. A system comprising:
- a wireless device configured to;
measure signal strength of wireless signals received from a wireless base unit and from one or more wireless repeater units; and
transmit the signal strength measurements of the wireless base unit and the one or more wireless repeater units to the wireless base unit;
each of the one or more wireless repeater units configured to;
measure the signal strength of wireless signals received from the wireless base unit and from the wireless device; and
transmit the signal strength measurements of the wireless base unit and the wireless device to the wireless base unit;
the wireless base unit configured to;
receive the transmitted signal strength measurements; and
select routing paths for communications based on an evaluation of the signal strength measurements.

Abstract
Various embodiments of wireless ambient sensor unit are presented. The sensor unit may include a wireless transceiver configured to transmit sensor data and to receive instructions. The sensor unit may include a sensor configured to measure an ambient condition. The sensor unit may include a controller in communication with the wireless transceiver and the sensor. The controller may be configured to compare data measured about the ambient condition to a stored threshold while the wireless ambient sensor unit is functioning in a low-power mode. The controller may be configured to exit the low-power mode in response to the comparison of the data with the stored threshold. The controller may be configured to cause the data measured about the ambient condition to be transmitted by the wireless transceiver as one or more messages in response to the comparison to the stored threshold.
