Hello, for about 4 years have a link of 5.8 km (3,6 miles) by two-mode WDS AP and two antennas 22.5 dbi grid.
At first 802.11b APs were about 60mW max, updated about two years ago 802.11g 200mW max.
For about a year, the link has been deteriorating gradually, until the point of being almost unusable.
I have tested with other AP, but still the same, so no problem will be if the antennas or interference by new facilities nearby.

The link used for VoIP, file transfer (especially FTP), Internet connection sharing between two houses and IP video surveillance cameras, so it has to be a link-quality, stable, low ping and the increased width banda possible.

The link is made between a point (AP1) and a house in the countryside (AP2). The AP1 is about 170m in height above sea level and AP2 approximately 265m high and the valley between average is between 180m and 190m in height.
AP1 just in front of a building that is approximately the same height of the AP and about 50m away. AP2 front of some tree branches.
Between the houses there are several lines of medium / high tension.

I am thinking of changing the link for a 2.4 Ghz 5GHz, because here the 5GHz band is hardly used, which is whether the characteristics of my link is adequate or better to continue with the 2.4 Ghz.

I would like to install an AP with integrated antenna for convenience and ease of installation.
I was thinking of installing a PowerStation5 as its power and antenna gain would be enough to guess my link, but I would like to install an 802.11n AP with this model supports it.
Today I saw the new NanoStationM5 unemployed if they are not sufficient to obtain a link quality, stable, with a low ping and a large bandwidth in my circumstances, or is small (especially by the antenna).

NanoStationM5 be enough?
Speed link that can set me in my circumstances?
I hope a better future PowerStationM5? Long time to leave?

PD: Excuse my English, I'm from Spain and use the google translator.

PD: I enclose a picture (very bad jeje) is better understood if the situation of the link.

Hello, for about 4 years have a link of 5.8 km (83,6 miles)

What is your distance in Km? They don't make sense. 5.8 miles would be 3.6 miles

Hi, has been an error, the distance is 5.8 km, which I believe are about 3.6 miles around.

Greetings.

I have a link between two NanoStation 5 of 5.5 Miles and it's given me 25Mbps and it's fair enough for your desire usage... Also you can't do it with NS2 but depends of your actual environment.

A real and sustained rate of 25Mbps would be very nice.

With the 802.11b link was a real and stable rate of about 4Mbps
When you upgrade to 802.11g rate rose to around 15Mbps. This was really enough, until it started to go wrong and lose speed and then cuts to occur and become stable link.
At present, transfer a relatively large flow of data, the connection is cut.

UBNT for technicians who are the only ones able habieis test with the NanoStationM5 to make a link with two NSM5 and get the speed that you announce a maximum 150Mbps, assuming the rest of condificones that affect the link is good, which is the maximum distance that support?
For 3.6 miles from my link, which you suppose that could be the maximum speed with two NanoStationM5 in WDS mode?

Greetings

Well first's of all the Nano M5 are not available yet. But you can do it with the Bullet 5 M5 with some antennas of 24dbi or 29dbi.

I have a few links with the following: 29dbi GRID 5Ghz wideband - 70.00, Bullet M5 80.00 on both site.

At distance of 11 miles I get 30Mbps TCP RX / 20Mbps TX in a heavy noisy enviroment

At distance of 19 miles I get 18Mbps TCP RX / 15Mbps TX

I don't have short distances link yet buy you can get like 50Mbps or more with your actual setup if you have good signals.

=)) for peanuts.....
