Unifi AC LR vs Lite? I want to install an access point for our office. and that is why I have brought an unifi ac lite. but it couldn't cover all of the building! our office has near 70 meters as foundation and is a two storey building. now I want to know if I buy an unifi ac LR(Long range), can it solve my problem? I mean is unifi ac lr stronger than lite?

You cannot light such a building with a single WAP. You need to do a site survey and plan how to distribute WAPs across the building to provide coverage. Each WAP requires a wired uplink.

The main difference between AC Lite and AC LR is 2x2 MIMO vs 3x3 MIMO for 2.4 GHz. WAP power is generally limited to 250 mW, so there's no difference. The LR should provide higher bandwidth and _a little_ more reach. See < for details.
