I Have one bullet2 and want to use with Omnidireccional Antena 15 Dbi, can you tell me wich is the maximum miles to connect stations ?
and how many station is possible to connect ?
What think about this, is correct my project ?
Since you didn't say include the antenna gain at the other end, I'll assume you'll be using a 22 dBi BBQ style grid antenna.
You should get 120 mile range. Of course you'll get a speed of only ten times that of a dial up connection and the link will be down 99% of the time and both antennas will have to be at least 3,500 feet above average terrain.
30 to 35 active connections would be a good limit for number of users.
What do I think of your project? Sorry, my crystal ball isn't back from repolishing yet.

Hello Juanito,
What height do you have at the Ap. What type of clients and what type of antenna are you using at the clients.
Thanks,
Mike

Hello friend Mike, the height of the antenna where the AP is 8 meters. and the site is free of any buildings or obstacles, they have customers who install antennas 12Dbi, which gives me recomendacion friend?

Good...thats some information we can work with.
AP 8 meters in the air and say 5 meters for the client gives you about nine miles line of sight. Of course thats not taking in Fresnel clearance. Your limitation is based on receiver sensitivity.
9 miles shoot at 6 Mbps data speed (which would be adequate for a 3 Mbps DSL internet connection at the head end, you'll have about an ten minutes a day down time. And 6 miles will give you less than a ten minutes of average daily annual downtime.
Bumping up you data seed to 24 Mbps (which is adequate for a 10 Mbps DSL internet connection at the head end), 3 to 4 miles will give you less than a ten minutes of average daily annual downtime.
