Greetings,

The antenna model and its positioning will also be a factor when it comes to the range.

Could you let us know what model antenna it is?

You can use the following data sheet as a reference guide for the external antennas:

5km radius is around 3 miles. Im not sure a 8 dbi antenna can push it that far. Are you trying to cover a large radius or just a confined area? If your not covering a radius get a Yagi antenna and shoot the beam in the direction you want the signal.

5km is a LOS rating as far as I know.

This 5KM distance is only going to be applicable in bridging situations. The following link shows how to use the distance calculations based on devices: http://www.cisco.com/en/US/products/hw/wireless/ps458/products_tech_note09186a008009459b.shtml

In theory, if you had a really strong direction antenna on your client you'd be able to get the 1310 as an access Point from 5km, but you'd need perfect line-of-site and you wouldn't be mobile...

As others had mentioned, if you're looking for an access point situation with that kind of range, then you need WiMax....

but if it is bridging you want, its just a matter of getting the other link to see this one (with a good enough antenna)
