Embedded Platform Wireless Solution for Smart Lighting Application


Intelligent street lighting is an important part of the energy conservation mix in smart cities. With digital networks and embedded sensors, intelligent street lights can collect and transmit data that help cities monitor and respond to any environmental circumstances, from traffic congestion to parking availability and air quality.    

Requirements & Solutions

A lighting company in US wanted to develop smart street lighting solutions by installing sensors and digital tools into their existing product lines. They also need to apply remote management through wireless technology. For wireless module integration, the main challenges are the working temperature range, wireless software security integration and specific antenna and RF certification. Advantech provided Wi-Fi, Bluetooth EWM-W162M plus support for -30~85°C wide temperature operation for wireless connectivity. EWM-W162M is 802.11 ac/a/b/g/n + Bluetooth 4.2 M.2 2230 (E-Key) Card. We worked with customer for the specific antenna+ RF certification while our IoT wireless solution can apply the necessary wireless security at customer’s platform ; support the WPA/WPA2 and WEP 64-bit and 128-bit encryption. The EWM-W162M also supports the IEEE 802.11i security standard through the implementation of Advanced Encryption Standard (AES)/Counter Mode CBC-MAC Protocol (CCMP), Wired Equivalent Privacy (WEP) with Temporal Key Integrity Protocol (TKIP), Advanced Encryption Standard (AES)/Cipher-Based Message Authentication Code (CMAC). These security features are necessary for smart city application.
