All our drivers can be equipped with wireless control features, with an integrated board that does not require any external box or a different form factor. Drivers with or without wireless control look exactly the same. LEDCOM International wireless controls operate at 3 different frequencies, depending on the customer’s requirements and applications. All three frequencies provide controls for the lighting functionalities, but each of them features some specific characteristics for certain additional applications and services.
- 169 MHz: this is unlicensed bandwidth, originally designated by ETSI for applications regarding tracking, tracing, data acquisition and meter reading. With a maximum allowed EIRP of 500mW (27dBm) and a 10% maximum duty-cycle, wireless transmission at these frequencies penetrates walls and spans a very long distance, making it ideal for street lighting in a dense urban environment or rural environment (very long distance between poles), but also for services like gas meter reading (the meter being generally located in hard to reach walled enclosures).
- LoRa / 868 MHz: a predecessor to the more recent 169 MHz solutions, mass deployment in this unlicensed spectrum of 868 MHz in the past few years has proven that transmission systems at 868 MHz deliver good range even in densely populated areas with high rise buildings (quite common in most European countries). The wireless control systems based on this frequency, while still narrow-band, provide more capacity than 169 MHz ones but provide lower transmission distance and obstacles penetration.
- Wi-Fi frequencies (2.4 GHz or above): wireless lighting controls based on Wi-Fi frequencies are not ideal for street lighting and should be installed only for in-building applications. The widespread availability of Wi-Fi routers makes them very easy to manage without installing any additional equipment. Once LEDCOM International Wi-Fi integrated drivers are installed you can manage your luminaires straight from your smartphone, tablet or laptop.
When LEDCOM International’s LED drivers are deployed, the wireless controls will automatically set up a network between the drivers themselves, with star, tree or mesh topology, depending on the requirements of the customer’s applications.
These communications networks built on LEDCOM’s drivers wireless capabilities are managed through LEDCOM International’s software suites, including LEDCOM International’s LMS (Lighting Management System) for indoor applications and PoleNet (for street lighting applications).
