At my house, I live in a hole with about ¾ mile of solid oak trees between me and the tower. 2.4Ghz in the late spring (meaning good, saturated leaves) I can run 4meg. When it rains, service will be spotty and sometimes drop. I would never install a customer in those conditions. We do have a few customers through trees, but with our noise floor here, we dont do much more than just a few trees at a pretty close proximity to our APs. I wouldnt even think about 5Ghz through trees at all. 3650 havent done anything through trees yet so I dont know.
900Mhz worked great for us for awhile but noise floor went too high and couldnt work around it so we pulled all our 900 equipment.

I guess I'm looking for success stories. I need to sell this to the partners. I know it can be done, and I'm fairly confident it will work in this situation, but they aren't. I've found a few instances online of people going 1 mile with 5.8 through some trees and still pulling off a -65 and 20Mbps of throughput - this was PTP. I know 3.65Ghz is supposed to be somewhere between 2.4 and 5.8 in terms of tree penetration, but I'm thinking this might be a good place to use 3.65, simply because of the lack of noise. I have never worked with 900Mhz as of yet. This was our initial alternative, but there is the added cost of deployment - $160 for a LocoM900 vs $80 for a NanobridgeM2. Literally doubles our ROI.

If you are using airmax - 2.4 should help 5ghz you may have some issues w/ trees however My suggestion is a mix - I noticed that you have not mentioned 900mhz 900 and trees especially at that distance - sub 1 mile is awesome - but doubt you will see the 10mbps speeds you wish. 5ghz is your best choice - if you can use it. setting up both 2.4 and 5ghz sectors may help - double the cost - but in the end - would allow you the most flexibility On Sep 13, 2010, at 6:20 PM, Nick White wrote: om this tower, no one in town would be more than .75 miles away. I'm thinking 10Mhz channels - 1, 6, 11. If we do this, I will likely use the UBNT shields that I've seen for sale with three 120deg sectors. ____________________________________________________________________________ _________ Glenn Kelley | Principle | HostMedic |www.HostMedic.com Email: gl...@hostmedic.com Pplease don't print this e-mail unless you really need to. ---------------------------------------------------------------------------- ---- WISPA Wants You!
