I can only think of one case where that would work and that is if the area that needs to be serviced via "near-distance" 2.4Ghz WiFi in the farm end can be enclosed by the azimuth and elevation beamwidths of the CPE210...Have a look at the diagram below and think where that gets you. In that case though the client would probably have to be setup in "AP Client router" mode, @R1D2 correct me if I'm wrong. In any case it'd be ideal to get a cheap AP to service the farm but if you care to test the setup below it'd probably work given the restraints ;)

Any AP would suffice, even a spare wireless modem/router that you may have which can be setup in WAN mode.

So on the farm, is this the setup I would need with the CPE510 and EAP110? CPE510 connected to switch. EAP110 and IPCamera connected to switch.

@shell820810, CPE 510 and EAP110 (or EAP225) is a very good choice for your use case. You would need one CPE510 at home, connected to the switch/router and an EAP110 connected to another CPE510 on the farm. The WiFi backhaul link is between the two CPE510. Our company uses this config to supply WiFi on large camping grounds - 5 GHz CPE for the backhaul and 2.4 GHz EAP110 for local coverage of the distant area. We even power both devices on each antenna pole using one power supply only (still have CPE510 V1 hardware with two Ethernet ports capable of PoE pass-through, which can feed an EAP110).

@RTouris, to answer your question about AP Client Router mode: yes, it could be used to supply clients inside the remote CPE's beam width, but it would also establish routing on the remote CPE (meaning there are two different subnets). If there is a router already at the local side (»home«), one would better use Bridge or Repeater mode if only one subnet is to be used, which is effectively the same as AP Client Router mode, except for the routing part. Difference between Bridge and Repeater is just whether the same or a different ESSID is used on the remote device's AP.

If you are having difficulties setting up the router in WDS mode, go get yourself a cheap-o dedicated repeater for less than $10 and that should do the trick :)

So it should work from the EAP110 to a repeater or routed?

You can repeat the EAP110's signal, but you will lose half the bandwidth on the repeater's side. Why don't you mount the EAP110 somwhere in the center of the farm and use a wired connection from the EAP110 to the CPE?
