Our superior IoT system consists of four structural layers; a data collection layer, communication layer, application layer and interaction layer. These provide extremely reliable, real time monitoring of large scale streetlight and junction boxes operation, control of streetlight dimming according to season and time change, collection of power consumption data, alerts light failure, and repair management.
Beside light control and monitor, the hardware also provides ready I/O ports for connecting additional signal input from multiple sensors such as for air pollution, vibration, light pole tilting monitor and alarm, etc. The platform software allows to add in various modules to expand its coverage of smart city applications, such as traffic monitoring.
On top of LED light vs traditional light energy saving, the system provides further 15%-25% energy saving and reduces the cost of management and patrolling manpower tremendously.
Our R&D team has developed a self-proprietary Sub1G wireless mesh communication technology, which overcomes the disadvantages of widely used Zigbee and LoRa communication protocol. It is a very reliable, long distance and wireless mesh network technology, and it is the lowest operation cost system compared to any of the other technologies available in the market for outdoor applications.

Let me explain the details.
For wireless communication, communication reliability is the most essential consideration. The reliability is mainly decided by its capability to bypass obstacles and interference, which is related to the node-to-node or node-to-gateway distance, the longer the better, and its capability to forward data from one node eventually to gateway either directly or via other node/nodes.
There are two types of wireless communication network, mesh network or star network. Under normal situation, a controller node talk to gateway, but due to various type of interference or objects, Mesh network allows one node to forward its data to another node which again pass the message to gateway, while star network only allows one node talking to gateway. That is to say, mesh network is a better technology compared to star network.
Zigbee is a mesh network, but its communication distance is very very short, in order to guarantee reliable communication, the distance between two streetlights is beyond the stable communication distance of Zigbee due to complications of outdoor environment.
LoRa is basically a long-distance communication technology, but it’s a star network, and to support its long distance of communication, small base stations are required, which is rather costly.
Our iNet system is Sub1G radio frequency-based technology, which we’ve developed from the system base structure/layer. It is our self proprietary mesh network, while supporting long-distance communication, that’s what I’ve said it combines the advantages of both Zigbee and LoRa, as a result, our system guarantees very reliable and stable wireless communication.
Cost wise, in case Zigbee will be used for outdoor applications, huge numbers of gateway need to be implemented to avoid data loss, which push the hardware cost to an extremely high level. For LoRa system, to support large-scale streetlight control and communication, small base stations shall be constructed, licence fee is also required to pay to LoRa company, so the system overall cost is also high. 5G nodes to central platform might be another technology in the future, but each node means cost to be paid to telecom service provider, in consideration of the number of streetlight in a city, it will be a substantial continuous annual cost.
Our iNet system use open free Sub1G radio frequency for communication between node to gateway or node to node. No substation required, no cost of system internal communication. The only communication cost is from gateway to CENTRAL platform, the annual cost is very much limited.
Hardware cost of all these types of products are similar except 5G node which will be a lot more expensive.
That is to say, when we look at both system hardware cost and operation cost, our iNet system is the lowest compared any other available technology and systems.
I hope the above information helps to elaborate our advantages.
All the very best,
