@CHASER,

CPEs are for long-range directional links, they use directional antennas and usually are used pair-wise, while EAP110 uses omnidirectional antennas, which have a much smaller range, but a broad 360º coverage.

You should not mix devices with different antenna types.

Also, CPE610 is not well suited as a repeater (for the same reason, it uses directional antennas with only 9º (H) / 7º (V) antenna beam width, limiting its coverage).

Typical use for CPE610 is a wireless backhaul. Note that both antennas need to have the same range, else the max. range is always the smaller range of both devices linked together. The following image shows a directional sector antenna on the right which also has a pretty long range suitable to link with distant CPE610s:

What exactly do you want to achieve?

@CHASER, what I have described refers to the antenna technology and also applies to all 2.4 GHz devices as well (CPE210, CPE220, WBS210 etc.).

@CHASER,

as I wrote, the longest distance is always the smallest distance of the devices involved.

If you want to connect standard clients like laptops or smartphones to a WLAN, the max. distance is the one the laptop / smartphone can cover with its antennas (that's ~40-70m outdoors, ~10-15m indoors). EAP110-Outdoor and EAP225-Outdoor are fine for this use case.

If you want to bridge long distances in the kilometer range wirelessly, you take a pair of CPEs with specially designed directional antennas.

There are no »repeaters« with which you can supply standard clients over long distances (>70m outdoors), that's technically impossible.

You can't beat the laws of (antenna) physics.
