|Normal Pole||Should collect telemetry data of its devices. Should receive data from nearby poles. Should aggregate data and forward it to nearby pole using Zigbee 3.0 or LoRa protocols or IEEE802.15.4 network protocol. Each normal Pole should be fitted with a IEEE802.15.4 transceiver. This transceiver should also support GSM/GPRS/UMTS.|
|Pole to Pole Communication||Poles should communicate with nearby poles with in a distance of at least 50m over a Zigbee 3.0 or LORA protocol wireless communication system supported by Ethernet IEEE802.15.4 protocol where applicable.
However the contractor could also use RF based mesh network for communication
|Concentrator Pole||Should aggregate communication of at least 10 Poles and forward it to control center through Fibre. The Zigbee or LoRa or GSM (based on IEEE802.15.4) transceiver on the concentrator Pole should also support ethernet connection consistent with IEEE802.3 protocol in addition to GSM/GPRS/UMTS. Otherwise if using mesh network, this might not be necessary.
Concentrator pole power and communication requirements should be taken into consideration.
A Fibre cable shall be run to the nearest Traffic control unit at a signal junction or control room directly to connect the concentrator Pole to the control Room.
