Connect your controllers to your network wirelessly and securely. #### Low Power ![Go Green wooden sign with a forest background](https://www.silextechnology.com/hs-fs/hubfs/Go%20Green%20wooden%20sign%20with%20a%20forest%20background.jpeg?width=1000&name=Go%20Green%20wooden%20sign%20with%20a%20forest%20background.jpeg) Silex's enterprise Wi-Fi bridge offers the lowest power consumption in the market. It can be  powered up by USB bus power eliminating the additional power supply source. --- ## Wi-Fi HaLow Low Power IoT Connectivity Silex offers Wi-Fi HaLow Low Power Access Point and Wi-Fi bridge for IoT connectivity suitable for your building automation. #### Sub-GHz Radio Band ![sub-GHz](https://www.silextechnology.com/hs-fs/hubfs/sub-GHz.png?width=251&name=sub-GHz.png) sub-GHz Wi-Fi does not interfere with legacy Wi-Fi in 2.4GHz and 5GHz as well as 6GHz band for Wi-Fi6, which allows users to offload IoT network from legacy Wi-Fi infrastructure. It also provides wider range and better coverage. #### WPA3 Security ![wpa3](https://www.silextechnology.com/hs-fs/hubfs/wpa3.png?width=249&name=wpa3.png) Wi-Fi HaLow utilizes the same Wi-Fi security known as WPA, which has been proved in the Wi-Fi infrastructure. Unlike other IoT protocols, HaLow installation inherits the security policy used for the existing Wi-Fi infrastructure. #### Seamless IP Integration ![wi-fi-halow](https://www.silextechnology.com/hs-fs/hubfs/wi-fi-halow.png?width=296&name=wi-fi-halow.png) As same as legacy Wi-Fi products, Wi-Fi HaLow network operates in the IP network. All you need is Wi-Fi HaLow access points and client devices to deploy the Wi-Fi HaLow infrastructure and IoT devices. --- #### Ideal Solution for IT-OT Convergence with 802.1X Enterprise Authentication Silex's Ethernet to Wi-Fi bridge seamlessly transfers data from Ethernet to Wi-Fi network when it operates in the single client mode. BACnet over IP and Modbus TCP data can be now over Wi-Fi. Silex's bridge is equipped with 802.1X Wi-Fi authentication by a Radius server. Therefore, you can integrate building automation system into the enterprise Wi-Fi network through silex's bridge. ![AdobeStock_451211118-1](https://www.silextechnology.com/hs-fs/hubfs/AdobeStock_451211118-1.jpeg?width=750&name=AdobeStock_451211118-1.jpeg) #### Relief from Complex Cabling **Silex's enterprise Wi-Fi bridge makes your controller installation much more affordable and much easier than ever.** Retrofitting legacy building with new building automation system often faces to technical and financial challenges due to cabling. However, you will barely find HVAC, VAV or other building automation system equipped with a wireless connectivity. Silex is with you to bridge between your Ethernet controller and your Wi-Fi IP network. ![Ethernet cables](https://www.silextechnology.com/hs-fs/hubfs/Ethernet%20cables.jpeg?width=600&name=Ethernet%20cables.jpeg) #### Simple Connection with your Controller The connection between your controller and silex's Wi-Fi bridge is simple.
