Remote Management in Street Lights
If you require remote management, we will fit a ‘master controller’ into one or more lights (depending on the site layout/no.of lights) which is fitted with a 4G SIM card and LoRA (Long range radio communication device) which connects with all other lights on the site to allow them to communicate with each other. The 4G SIM card in the master controller collects and transmits all data to the cloud, which allows you to view the units on the portal. The other lights on the site are called ‘Workers’ and are fitted with LoRA enabling them to communicate with the master controller.
To ensure a stable connection between the master controller and workers, in usual circumstances we work to a ratio of 1:80. However, we also consider the terrain, surrounding obstacles (buildings/tree cover etc) so this number may be increased.
The maximum transmission distance between the gateway and the worker is 2km in the open field. But the distance in actual use is recommended to be controlled within 1km of sight distance. However, if there are a lot of obstacles between the gateway and the worker transmission between the two maybe impacted. In such cases we would increase the number of gateways appropriately.
