Elegro’s ThinkNote G4 is a Wi-Fi Halo Gateway with Ethernet and 2.4 GHz Wi-Fi, allowing you to connect compatible devices or extend the range of existing devices when using two gateways or multiple gateways in an 802.11s mesh configuration.
It is based on (legacy) Mediatek MT7628N MIPS processor, paired with Quectel FGH100M, Morse Micro MM6108 Wi-Fi HaLow SoC launched in 2022, with data rate up to 32.5 Mbps and line up to one kilometer.

The ThinkNote G4 has a Wi-Fi Halo Gateway, a Wi-Fi Halo antenna (915 MHz), a 2.4GHz antenna for regular 2.4GHz Wi-Fi, and a USB-C cable for power. The antenna is tuned to the 902-928 MHz band suitable for the US, Southeast Asia, Japan, Australia, and some other countries, but not the 868 MHz band specifically used in Europe, which may need to be changed depending on your country.
We’re not told anything about the software, but I saw a screenshot with Linux 5.15 and “OpenWrt 1.1,” which means it’s probably a fork over OpenWrt with Linux 6.12, even though the MediaTek MT7628N supports upstream OpenWrt. I suspect they use the OpenWrt fork from Morse Micro, as do most MM WiFi HaLow gateways. We also have more information about the LuCi-based user interface via the user manual. The gateway can be configured as a client (STA) or gateway (AP) in standard Wi-Fi HaLow mode, or as a mesh gate/point when using the 802.11s standard.
Target applications include remote camera monitoring, industrial automation control, asset management and monitoring, smart home, smart city, Wi-Fi/Ethernet/Wi-Fi-HaLow extension and bridging, and rural/remote Internet access.
This type of solution isn’t exactly new, as we’ve been covering products like the WiFi HaLow Extension Kit and AsiaRF AP7688-WHM WiFi HaLow IoT Gateways since at least 2021. More recently, HalowLink 2 has been replaced with more powerful hardware (Mediatek MT76621, D33MHz @ 82core, 82-core 32MB NAND Flash, MM8108 chipset), and the main advantage of ThinkNode G4 is its affordability.
