My intentions are to balance 10 MHz channels if I can with in opposing directions with 90* antenna. 3.65 90* antenna would fill in the other two directions.
I was excited to see RunCom come out with a 4x4 or 6x6 MIMO (whatever it was). I'm sure it's expensive. Sure it's not worth it for me, but maybe it is for you foliage guys. Increased link budgets, increased speed. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original Message ----- From: "Steve Barnes" <st...@pcswin.com> To: "WISPA General List" <wireless@wispa.org> Sent: Thursday, August 22, 2013 12:16:56 PM Subject: Re: [WISPA] Latest trend for heavy wooded areas I have 1 Tower with UBNT 900Mhz and 1 tower with MT and XR9 cards. Both have ~25 clients. The MT tower Has more trees and a Single V-Pol Omni. The UBNT has a the UBNT 120* sector so it is limited to the direction it is pointed. I get the same throughput on both. I can give Clients a 5MB service no issues depending on SNR but most have a 2MB or less service. They both work. But these are very Rural and when the RTK farming system is active for Planting or Harvesting then it gets a little dicey. But they have no other option when they call and complain during those times I explain that it is noise I have no control over, Sorry. [my opinion] Putting multiple 900Mhz Radios on a single tower is IMPOSIBLE without GPS sync. The Noise from one to the other, even from bounces off of buildings 1 mile away makes the noise too high for the sector. I mean come on you only have 25MHz to play in and in today’s world to offer the speeds you need to on 900 you need to use 20 MHz. Even if you use 10Mhz and use the top and bottom you only have 5MHz Separation and on the same tower unless you are on opposite sides of a solid steel water tower, you will have enough bleed over that your receive sensitivity will be shot.
