LoRaWAN network protocol features low power consumption of terminal devices, high penetrating ability and signal protection from interference. Direct LoRa modulation provides a communication range of up to 15 km in open areas.
For urban environments, the communication range depends on conditions and takes into account different indicators:
- Building density, building height;
- The material of walls the radio signal has to go through;
- The base stations location height and their quantity;
- Presence or absence of radio interference from mobile operators.
The maximum range in urban conditions, achieved in Atiko projects, is 5 km. The lie of the ground and low building density contributed. For projects with high building density, this rate turned out to be much lower, but the installation of additional stations completely solved the client’s problem. In addition, it became possible to quickly connect more different devices to the network.
The data transmission range in the LoRaWAN network is provided by the use of wideband modulation at the physical level. The more interference there is for the radio signal, the shorter the range.
How to calculate the signal range for a specific project?
To understand the range of the signal between transmitters in a specific project, it is necessary to study the features of the urban environment where the network is being built. So, if the terminal devices are located in deep basements, then the signal range can be about 300 meters. But it is worth noting that the obstacles in the signal path may differ, therefore, accurate calculations must be executed directly when deploying the network.
Why is the LoRaWAN network favorable in urban environments?
Despite the low signal range in urban environments, the LoRaWAN protocol has a number of advantages that distinguish it among other wireless and wired communication options.
Connecting sensors located in hard-to-reach places. For example, if you need to connect to the Internet of things a sensor located in a deep basement, then other wireless networks will show an unstable result. For wired networks, serious costs would be required.
battery life of terminal devices. The operating time of the terminal devices for the LoRaWAN network from a built-in battery reaches up to 10 years.
Each project is individual and the customer chooses the most “convenient” and favorable data collection and transmission technology. If you need to connect a large number of control/accounting points, it is more efficient to deploy the network and cover a large area, “get” into the basements.
The Atiko company implements projects that allow connecting a wide variety of sensors to a single network, organizing a single system for collecting all the data required by the customer. You can read more about the implemented projects in the “Solutions” section.
