50km licensed link?

[rebelwireless]

Anyone got any advice on a 50km licensed link for up to 200Mbps by say 50Mbps? I have a subdivision HOA asking for a buildout in the sticks 50km out that I can hit with an AF5X, but I don't have the channel capacity on that tower to give up 20Mhz.

other info, perfect 5Ghz LoS (one side a 150' tower, other a mountain side). grid power on each side so no power draw concerns. up to 4' dishes would be acceptable, any bigger and it's just too much hassle to work with.

Would love something upgradable. Probably only need 60x15 to start, but anticipate 180x45 or so within 2 years, and the tower could potentially feed another subdivision in the future.

Thanks for any thoughts.

30 miles is a LONG shot for most licensed links.
SAF 11 GHz would require too large of dishes for reliability.

The only thing that would work here that I know of is the AF5X or MIMOSA B5C, personally I would chose the AF5X with 34dB dishes because it does provide more bandwidth in the same spectrum.

But to give MIMOSA credit because they are nice links too I do plan to buy a ton of their new B5 Lite links when they become available for short private DFS links from tower to high end commercial customers.

Exalt's EX-s link calculator says that 11Ghz w/ a 30Mhz channel w/ 16QAM and 3' dishes should be 3.5 9's at 95Mbps FDX. 3.8 9's w/ 4' dishes. I think I'm stuck w/ 50/50 on the link though, and 94Mbps isn't enough for a 3 year plan. and then there's the price....ouch.

I do not care what they say, 30 miles will drop in mild rain with 3' dishes

We have a 2+0 SAF Lumina HP 11ghz link with 4ft dishes going 40 miles and they work great at 256qam, never had any problems. I probably won't buy luminas now though since they are only 370mbps and for the same money you can get atleast double. Checkout the IP20C-HP or PTP820S
