i’m looking for hardware recommendation for the 3 PtoP links which we’re currently planning. We start with 150Mbit uplink from location B. So i would like to be able to transport that bandwidth over the PtoP Links in both directions.
Location A <= ~692 meters => Location B <= ~830 meters => Location C <= ~350 meters => Location D
At Location C there is already a link with an old Groove 5Hn and a grid antenna. Here i can see that the noice level is quite low: -115dBm.
My first idea was to use SEXTANTs for this new links but i’m not sure whether 18dbi antenna gain is enough to get a good signal, especially for the 830 meter link.
And the next question is: should i directly look for ac equipment?
Also an option is to take the StationBox® XLStationBox® XL CARRIER CLASS (http://www.rfelements.com/en/products/cpe-enclosures/stationbox-xl/) Antenna/Enclouser and put a RB911 in it. in that case i could change the board for an other one with AC later.
Using the distance that you posted, as all of them are less then 1 kilometer, I would use the Sextant. It has the build in antenna and is a one piece device, much easier to work with.
Be sure you get the SEXTANT G 5HPnD
The big thing to remember is DO YOU HAVE A CLEAR LINE OF SITE?
The Fresnelzone should be free. All 3 links go mostly over free field. For the long(830m) distance the ground half why is not just free it’s also a few meters lower as the ground on both ends. I still need to visit location B to have a look from there and measure the height with a GPS. But from C and A i can see that location quite good.
i’ve used the first generation SXT’s and if there was not a significant improvement of the antenna i would not use them for a 800m link. for the ~300 meter link it might be ok. but the 5Ghz SXT with gigabit is not much cheaper as the SEXTANT. why not take a antenna with more gain. it’s always better to have more antenna gain and use less tx power especially at location with multiple antennas.
You are right about that. More gain on the antenna won’t hurt. But still both Sextant and SXT can be used at 5-6km with no problem. On a site with multiple antennas it’s better to use antennas with narrower beam to avoid self interference.
