What kind of range or coverage can I expect from the 400mw access point?
The coverage and range on the VX-AP400 and all access points will depend on line of sight, humidity and materials that may obstruct the signal to pass through. Buildings with cinder block, brick and concrete will have a harder time to pass the signal due to the density of the material compared to drywall. High humidity can also obstruct signals due to signals reflecting off from moisture.
