 Unlike traditional sensors like UV and infrared sensors, ZigBee sensors are in use.  RTLS supports features such as exit alerts, patient tracking, patient safety and asset tracking which are important in hospitals.  It has been introduced by a San Diego based company by the name Awarepoint.

 RTLS systems uses Zig Bee which offers the following features such as –  Extra Encryption Services (application and network keys implement extra 128b AES encryption).  Association and authentication (only valid nodes can join the network).  Routing protocol: AODV, a reactive ad hoc network has been implemented to perform the data routing and forwarding process to any node in the network.

 Three types of nodes exist in a ZigBee Network Coordinator: - the "master" device, it governs the network. Routers: -routes the information which sent by the end devices. End device (the motes - the sensor nodes) :- the ones which take the information from the environment. ZigBee creates star topology.

 is primarily used to achieve point to point and energy efficient communications.  ZigBee defines extra services (start topology routing, encryption, application services) over  ZigBee creates semi-centralized networks where just the end devices can sleep.

 Unlike infrared sensors it offers persistent room level location tracking.  Avoids interference with medical equipment.  Maintains separation from Wi-Fi network.
