We plan to implement a wireless link for the distance of 55 kms and we expecting min 20 mbps throughput. i’ve enclosed elevation profile of the two sites. Pls friends guide me in this case in choosing the right product and tower erection considerations.
SITE 1:
11° 9’56.90"N
77° 3’11.24"E
SITE 2:
11°13’27.53"N
77°33’10.28"E
i don’t know much about your budget but for 55 km i would go for 2 solid dishes 90 cm (32-33 dbi) dual polarity and R52Hn wireless card using NV2 protocol. For the board i could suggest rb433ah or something similar based on your needs (bridging , routing, etc…)
You also have to simulate a link budget to see where your fresnel zone is going to be (at least 60% of the fresnel zone).
You will find a lot of free tools on the web if you try to google “wireless link budget”.
I hope this helps
Thanks fabfab10 for ur suggestions. I have also posted a topic Rf link for 30 kms. pls consider that too and give me a suitable reply. In that post i’ve attached the link analysis result. pls find that too.
An ambitious plan
The only dish I know, that should deal with these conditions is

I would use Dbii Networks F50N Pro instead of R52HN.
Use Radio Mobile and check what height the towers should be. If I write exact geo coordinates for both sides of the link, I can try to make the simulation for you.
hi so did you deploy the 55 kms link?? please update me with your results…
metal 5 and 30 km from db grid antenna system currently has 38 employees. -64/-65 DBm signal values tx / rx rate would recommend everyone from 210.0Mbps/210.0Mbps
how many db grid?? and Metal is not MiMo still you getting 210Mbps??
wireless gold 30 db antenna 100 euro and metal 5 1x1 MiMo 210 mbps wireless value
