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.
