Recommended design guidance:
AP-275 - 150m radius
AP-365 - 100-125m radius
Maximum tested client range:
AP-275 - 200m radius
AP-365 - 175m radius
Maximum observed distance
AP-275 - 300m to phones/table, 600m to a macbook pro3 in clean RF (requires modifications to AP radio, HIGHLY dependent on client)
AP-275 mesh range
easily 500m, we have done up to 1km, but not recommended. If you need more than 500m, use the AP-277. Note that mesh is HIGHLY dependent on RF environment, if it's clean or noisy, channel availability, etc.
