What do i need for a reliable 35 mile backhaul that can produce atleast 5mbps throughput?

Will Tranzeo Tr-5plus radios work with 32db dishes?
Most of the 802.11a based stuff will do this, lock the throughput to something lower than the max to get a fade margin of at least 30 db for a reliable link. You can also look at the Trango T-Link 10 which will work as well.]]> http://www.dslreports.com/forum/remark,20437653 Mon, 05 May 2008 23:44:32 EDT Re: RELIABLE 35 mile backhaul, what do i need? http://www.dslreports.com/forum/remark,20437049 schj98 : I currently run a Tranzeo TR-5Plus-N link with 32dBi dishes at 37 miles.

Signal is -53dbm with a throughput of 15mbps TCP and 19mbps UDP.

Link has been up for almost a year and a half with 0 issues.

Of course LOS is key especially in a link at this distance. Run a radio mobile plot before your buy anything.

Hope this helps.]]> http://www.dslreports.com/forum/remark,20437049 Mon, 05 May 2008 21:40:09 EDT Re: RELIABLE 35 mile backhaul, what do i need? http://www.dslreports.com/forum/remark,20436006 AMD Phreak : Yeah recieve power is -58dB. I'm leery about having such a low fade margin though on a path like this in our mountainous terrain. I'll PM you Hal so we do not threadjack this post.. :)]]> http://www.dslreports.com/forum/remark,20436006 Mon, 05 May 2008 18:06:48 EDT Re: RELIABLE 35 mile backhaul, what do i need? http://www.dslreports.com/forum/remark,20435981 dongato17 : I think you should get about a -55dBm signal or so, which sounds like what your calcs are saying. If you don't need the full speed, you can use a lower modulation and get more fade margin. 20dB should be fine though.

I am looking at a path thats 34.5 or so miles with a clean fresnel using Ligowave product. With the 27dB TX power and 34.4dBi dish on one side and 31dB dish on the other I get about 21dB of fade margin. Thats not very hot if you ask me.]]> http://www.dslreports.com/forum/remark,20435714 Mon, 05 May 2008 17:14:11 EDT RELIABLE 35 mile backhaul, what do i need? http://www.dslreports.com/forum/remark,20435192 kf6ytc : What do i need for a reliable 35 mile backhaul that can produce atleast 5mbps throughput?
