ZR 3 and it will send a special unicast message called a Route Response message back to ZC using the temporary route constructed in the initial step of Find the Destination This message is used by intermediate devices to establish a permanent route back to ZR 3 TON s ZR4 ZR 3 e Routing Table Entries for A Because ZR 3 is a one hop neighbor ZR 2 does not need to store routing information about it ZR is not involved in this part of the discovery process because it was not selected by ZC in the initial route step of the find the destination mS Q ON KI ZR 4 ZR 3 When the message reaches device ZC the route discovery 1s completed and the new route can be used to send data messages from ZC to ZR 3 3 2 4 ZigBee Network Architectures ZigBee technology is slower than 802 11b 11 Mbps and Bluetooth 1 Mbps but it consumes significantly less power The ZigBee specification is a combination of Home RF Lite and the 802 15 4 specification The spec operates in the 2 4GHz ISM radio band the same band as 802 11b standard Bluetooth microwaves and some other devices It is capable of connecting 255 devices per network but when you deploy that we suggest around 30 sets of ZigBee device in each the network The specification supports data transmission rates of up to 250 Kbps at a range of up to 30 meters Depend on environment For higher reliability we suggest the data transmission rate 1s around 20 Kbp
