> 2.4g wifi has insufficient range

Is this about propagation over obstructed Fresnel zone paths?

I ask because generally 2.4GHz has much longer range than 900MHz due to the much higher gain antennas achievable at higher frequencies.

But if there's something in the way (trees, buildings, a bit of terrain), then 900MHz can work on a path when 2.4GHz doesn't. I suppose that's one definition of "has sufficient range".




Yes, forest is my exact use case, with roving devices that are too cheap to have phased arrays so get stuck on low gain antennas.


How would these roving devices even use a phase array? They are moving. Sounds like you dont want directional coverage and just need repeaters
