Not to beat it to death but I'm looking at supposedly having the ability of putting 75 customers on an AP, any cost difference to go sectorized seems foolish if I am looking at a maximum of 15 customers in these instances. Are the ePMP 120 deg sectors really 120 or are they more like the 90 degree of the 120 degree Ubiquiti? John Woodfield Delmarva WiFi http://www.delmarvawifi.com cell (410) 708-1937

At the lower price point of ePMP equipment, I think you might be able to justify sectors at 15 subs. Depends on ARPU and whether the additional range would increase the subscriber count. With the ability to GPS sync, you only need 2x the spectrum for 4x the capacity.

It works for low range areas but its tough to justify sectorizing with 15 customers on a tower...

The highest you usually see in a 90 degree sector is maybe 17-18 dBi. What you gain in horizontal coverage, you give up in either gain or vertical beamwidth, and you really don’t want narrower vertical than the 17 dBi sectors. So for 4x the horizontal coverage, you would expect to give up about 6 dB of gain, so 13 dBi is already impressive. But it is also important to look at the pattern for an omni, some of them have 3 dB or more of variation with azimuth, so an 11 dBi antenna with a nice circular pattern might be just as good as a 13 dBi with an ugly pattern. Different models may also have electrical downtilt, maybe null fill although that seems hard to find in 5 GHz omnis. In general I have not been impressed with any of the 5 GHz dual pol omnis I have tried, they work, but range is nothing to write home about.
