Max Distance using an omni directional antenna

Can anyone give me some idea of what sort of distance could be achieved (line of site) using the following configuration.

AP is Mount 15-20M high on a tower and is a MT 532 with a CM9 and 15dbi omni antenna

CPE is likey to be either a Seano with 200mw Card and a 23dbi directional grid antenna

or a MT112 with a TL-WN560G 100mw card and 23dbi directional grid antenna.

or any other setup that some can suggest that would give me good service and the further distance.

Thanx in advance

You don’t mention whether you’re using B or G, so I’ll assume B since it’s longer range. With that kind of gear, in a quiet rural setting, I’d bet on 10 miles or more. Swap that CM9 for an SR2 or similar card and you might push out to 15, figure 10 with a solid 11Mbit link and falling off to 1Mbit at the far range.

If you’re in a dirty RF area, cut those ranges in half, or more.

A lot of this depends on where that omni is also. If it’s up high where it can hear every signal for 30 miles in every direction, all that hash keeps it from hearing a gap for it’s own transmits.

Hi UniKyrn

I am in a fairly low noise area on 2.4 if I do a scan on the MT Unit I only pick up 3 AP’S with levels of -84, -85 and -91.

Thats a fairly long range for an Omni. I will give it a go anyway.

Thanks for you help

If your omni is already mounted in its final location and you only hear a couple of residential AP’s on a scan, yep, that’s a quiet area. I’ve seen one up high on a hilltop come back with several screens of other AP’s, the site was pretty much unusable.
