Morse Micro MM8108-M20 is a high-power Wi-Fi HaLow module based on the MM8108 SoC and a high-power amplifier delivering up to 28.5 dBm transmit output power, alongside a surface acoustic wave (SAW) filter tuned for the 902-928 MHz band of the North American market.
Other MM8108 modules, such as the Quectel FGH200M Wi-Fi HaLow module, are limited to 26 dBm Tx power, but US and Canada regulations enable higher power transmissions, and by extension longer range. The obvious downside of the MM8108-M20 is that it might be outright illegal or may require a special license in other countries.

Morse Micro will usually let OEMs design modules based on their WiFi HaLow chip, and the MM8108-M20 appears to be the first module from the company itself.
There’s very limited information about it, since the Australian company only published a press release and has yet to provide a product page for the new high-power WiFi HaLow module. Going from 26 dBm to 28.5 dBm should extend the range by about a third. The company expects the module to be used in surveillance cameras (the most common application for WiFi HaLow) and access points.
