That is my thing here. I started small, omni on each tower in rural areas. I expected more customers than I got, so I'm very glad I didn't take out a monster loan to build a super network. I'd never pay the loan off.
The only tower I had with sectors was taken out by that storm and I never hit the capacity to really take advantage of the sectors. It is in a location overlooking town though, hard as hell to find a clean channel, much less three or four. The whole system is due for some upgrades, which I'm working on right now. Still have mostly single polarity clients and 20Mbps PtP shots between towers. ----- Original Message ----- From: Mathew Howard via Af To: [email protected] Sent: Saturday, November 08, 2014 9:41 AM Subject: Re: [AFMUG] Now I'm impressed. Omnis definitely do have their place, they're certainly not something that should be used everywhere though. I have run into situations where noise is less of a problem with omnis than sectors... it all depends what it is and where it's coming from. We often put up omnis on new towers (especially if they're on the edge of our network) and then switch over to sectors when it becomes necessary - which is sometimes never. ------------------------------------------------------------------------------ From: Af [[email protected]] on behalf of Mike Hammett via Af [[email protected]] Sent: Saturday, November 08, 2014 8:57 AM To: [email protected] Subject: Re: [AFMUG] Now I'm impressed. Four sectors would allow frequency re-use. I do admit that in conditions with significant noise in all directions by many transmitters, leaving only one clean channel you're left with an omni or something like LTE's wizardry that uses the same channel everywhere. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ------------------------------------------------------------------------------ From: "Mark Radabaugh via Af" <[email protected]> To: [email protected] Sent: Saturday, November 8, 2014 8:54:38 AM Subject: Re: [AFMUG] Now I'm impressed. I actually shot myself in the foot once doing this. I took down a 900 omni and put up 3 120 sectors thinking it was going to be great. Not at all what happened. Turned out the omni was running on the only clean channel. With the 3 sectors and only 3 non-overlapping frequencies available there was no combination of channels and directions that worked as well as the omni it replaced. After rotating sectors and frequency plans around for days we found something workable, but it wasn't at all what I expected when we started the project.

Omni's have their places. Physical space limitations, frequency congestion, low density, mobile applications, cost, etc. Sometimes it's the right tool for the job.

We had a tower taken out by a storm. When we replaced it I finally upgraded to 802.11n as I wanted and went with a DP omni rather than sectors. RB711 UA2HnD + ARC 13dBi DP Omni I'm fine tuning the network, made some adjustments on a tower 12 miles away, one customer didn't come back up. I started checking my other APs as sometimes they'll hop if close enough, didn't find anything. I went to the new AP 12 miles away, the client was connected to it from a little over 12 miles apparently off a sidelobe of an Airgrid 16dBi. The grid is pointing at least 20 degrees off, and I never expected that shot to work if it *was* pointed the right direction. I'm impressed. -- Mark Radabaugh Amplex [email protected] 419.837.5015 x 1021 -- Mark Radabaugh Amplex [email protected] 419.837.5015 x 1021
