Wi-Fi Bridge for Gateway-to-Cloud Communications

In the standard Enlighted system architecture, each Gateway device connects to a PoE switch that is connected to the IT network. The Gateways securely communicate to the Manage in the Cloud (“EMC”) using HTTPS through the IT network.


An alternative to the standard architecture for situations where the Cat 5 and PoE installation and cabling is not feasible, connect each Gateway to a Wireless Bridge that connects to the IT Wi-Fi network. Manage in the Cloud is reached, as before, through the IT network via HTTPS.



Each Enlighted Gateway will connect to the PoE+Data port of a TP-Link TL-POE150S PoE Injector (or equivalent); refer to TL-POE150S document.

The Data port of the PoE Injector will connect to an Aruba 501 Wireless Client Bridge (or equivalent); refer to Aruba 501 Wireless Client Bridge document.

Both devices would access nearby AC power.


The Wireless Client Bridge acts as a client on the local Wi-Fi network. The IT Administrator can configure the Bridge to use the appropriate security protocols [WPA2-PSK/AES/TKIP/etc.] and credentials [802.1x, etc.] for the specific network. The Bridge Data Sheet lists the supported protocols.

The IT Network should be configured to allow the Gateways to connect to Manage in the Cloud. The ports needed for outbound connectivity include:

  • UDP Port 123 for NTP
  • TCP Port 443 for HTTPS

Open up one of these ports on the customer network.


An Enlighted system used for Advanced Lighting Control consumes minimal Wireless LAN bandwidth because each Enlighted Sensor is self-sufficient in managing the fixture to which it is connected; there is no System Master or Lighting Controller or Zone Master device. Each Sensor makes measurements and takes actions independently of such supervision.

The traffic offered to the Wireless LAN primarily consists of historical sensor data periodically sent to Manage in the Cloud for analysis and report generation. For every 100 sensors, the Gateway consumes a maximum of 12kbps, with an average of 4kbps. This is a minuscule portion of the Wireless LAN capacity.

Note: The Enlighted system was specifically designed to not require a Controller or Master device, thereby eliminating the vast amount of traffic typical of competitive systems.
