http://i62.tinypic.com/11qpp2w.png I have a Bullet M2 with a 12DBi Omni Antennae. I have 4 blocks of Rooms and about 4 rooms in each block. There is a TP-Link 300Mbps access point in each Block. The first two blocks and their access points connect just fine to the bullet m2 and give internet, but because of the bricked walls the bullets signal has trouble penetrating the walls after the second block. If you step just outside the rooms on the 3rd and 4th block you have internet without a problem ( but signal is about 3 bars at the end of the 3rd beginning 4th Block. The problem is I need to connect and give internet to the third and fourth block. We were thinking to get a loco because its cost effective , but if a Pico would do the trick then we will have to get it. I was thinking of setting them up as a AP Repeater and then connecting the final TP-link Access points to the Loco or Picostation or whatever we decide to get. What is the best solution for this? A bullet connecting to a Pico will have to do if we can get this to work, but setting up as an AP Repeater requires an open WEP encryption, is there another means of setting these up so that they at least have a WPA-PSK encryption? We have used the bullet and picostation setup before but will it work for this scenario. Need a cost effective solution ASP. I have attached a crude diagram of what the area looks like, but I take it you already know what I am talking about. The blue circle is where the bullet is and the red circle is where I need the or think I need the picostation to be. There is an elevation from the bullet to the i.e. Picostation.

If you use the Ubiquiti radios in AP WDS repeater mode then you are limited to WEP security. See here: https://community.ubnt.com/t5/airMAX-Configuration-Examples/airMAX-Configure-a-Wi-Fi-access-point-cluster-in-AP-WDS-repeater/ta-p/420005

I would not set it up like this unless your budget is really tight. One thing is the weak encryption and the second thing is the 50% hit you will take to max throughput to your clients. This is compounded by the fact the Bullet is a SISO device. The max link rate for a bullet is 150Mbit/s if you use 40Mhz wide channels, which is generally a bad idea on the 2Ghz band. So with 20Mhz wide channels you are looking at a link rate of only 72Mbit/s (with a throughput close to 25Mbit/s). So if you...

Your diagram is being blocked by my work porn filter....doesn't like naughty network diagrams i guess :)

You should be able to use a direction ubiquiti device to talk to the bullet. You would run it in bridge mode using WDS. You would then connect it to the tplink running the tplink as a simple AP. This is only sorta a repeater since the AP can run on different channels than the bridge going back to the bullet. If the tplink device was a router you could run the link back to the bullet in clinet-bridge mode without WDS.

I don't know why you would have to use wep. ubiquti stuff support WDS in WPA2 mode. Since you can I would use different SSID and keys for the connection between the bullet and the direction bridge on the building and the AP that is inside the building. This would keep these networks a little more isolated.

Pretty much you design is the standard WISP design. You run one radio network to backhaul the signal from each building to the central location and in each building you run a totally unrelated radio network. This is the way "repeaters" used to be done before the age of the $29.99 range extender garbage that you see sold in walmart.

Thanks for the input bud. I have checked it out and have been informed in the past that if it is setup AP-Repeater style then only an open wep encryption would work. Why, I don't know. However I have confirmed that a WPA2 & AES encryption is the best method and will work, as long as the Pico and Bullet are exactly the same setup, besides the IP's it should be fine. I have also been informed that the best method as it has an omni is the picostation. The loco is mainly used for point to point. The Pico, obviously, has a 360 degree, however the loco only has a 60 degree. Locostation could and should work however I have not tested this? Can anyone confirm? and Yes @Bill001g that is by far the naughtiest diagram in my library. Have you tried VPN? :p

The thing I always liked about ubiquiti is they run pretty much the same software on all their units. I would have to go look at the exact models I have used but I know I ran a point to multipoint install where I used a central omni and directional client and we ran it all wpa2 with WPS. It went is so easy I forget the details. It was something I helped my brother put in for a volunteer fire dept a couple years ago.

In general you can use omni on both ends if the signal is strong enough. It tends to be best to use directional if you can because it reduces interference received from other wireless devices.

Since I work for IT I can actually bypass the filters it is just logged that I did it. VPN won't work because the filter also have lists of proxy/vpn services that are also blocked. We know all the tricks...in fact it can detect openvpn since it does not follow the SSL standard exactly so we can even block the user who thinks he can run a private vpn in his house....now if he uses openssl or uses a commercial appliance he can.

So with 20Mhz wide channels you are looking at a link rate of only 72Mbit/s (with a throughput close to 25Mbit/s). So if you repeat it the max throughput would be like 12Mbit/s or so for all the rooms to share.
I assume the Bullet, besides giving wifi to the rooms, is also giving wifi to the reception area?
So I would do one of the following:
1) Use a Loco M2 to capture the signal from the Bullet, then use a Pico to re-transmit on another channel.
Actually that is the only thing I can recommend without knowing more about your setup and the distances involved.

Would it be possible to wire the TP-Link radios to the LOCO? If so you would not have to re transmit on the PICO.
Ok I just reread your original post. It looks like you are already repeating the signal from the Bullet through the TPlink AP's. If so then adding a Pico in repeater mode is really not a good idea (besides the other reasons listed).
