Monitoring and Tracking of Wireless Sensor Devices
First Claim
1. A healthcare monitoring system comprising:
- a plurality of sensor devices for attachment to patients for the purpose of monitoring physiological data, each sensor device comprising a radio frequency transceiver;
a plurality of base stations arranged in use to be placed at respective fixed locations within a healthcare facility, each base station comprising a radio frequency transceiver for communicating with one or more of said sensor devices for the purpose of receiving monitored physiological data; and
a central server coupled to said plurality of base stations for the purpose of receiving and recording monitored physiological data,wherein each sensor device is arranged in use to attach to a first base station that is within range, and to attach to a second, different base station that is within range when contact with said first base station is lost, attachment of the sensor device to a base station being registered with said central server; and
each said base station being configured at initialisation, or upon detection of interference on a used channel, to perform a channel selection process, the process comprising;
retrieving from said central server a list of currently unallocated channels within the system;
scanning said unallocated channels to determine if one channel is available and, if so, selecting that channel and notifying the central server of the selection;
if none of the unallocated channels is available, retrieving from said central server a list of currently allocated channels within the system; and
scanning said allocated channels to determine if one channel is available and, if so, selecting that channel and notifying the central server of the selection.

Abstract
A healthcare monitoring system includes a plurality of patient wearable sensor devices for the purpose of monitoring physiological data, each sensor device including a radio frequency transceiver. A plurality of base stations are provided at respective fixed locations within a healthcare facility, each base station including a radio frequency transceiver for communicating with one or more of the sensor devices for the purpose of receiving monitored physiological data. A central server is coupled to the base stations for the purpose of receiving and recording monitored physiological data. Each sensor device is arranged in use to attach to a first base station that is within range, and to attach to a second, different base station that is within range when contact with the first base station is lost, attachment of the sensor device to a base station being registered with the central server.
