Hi Mike, to be honest I just don't think there is enough bandwidth in the band I need to work in.
If I could do point to point I would do it but ptmp just seems to be
Hi Paul, That is the specific use case for horns. The important points are that typical 'sector' antennas have lots of side- and back-lobe characteristic that essentially introduces noise from 360 degrees of the antenna direction. Horn antennas have minimal sidelobes and pretty much 90dB front/back ratio. What it means is that a normal antenna will generally get more than 50% of the noise from sources outside of the nominal beamwidth. Therefore, use of horn antenna can decrease noise levels by half or better. Secondly, since horn antennas come in as small as 30 degree beams, that offers an average of 1/12 th the noise level experienced by a 360 degree antenna, 1/4 of a 120 degree, etc. There are lots of other very compelling reasons to consider hor antennas to replace traditional sectors - If you look around for case studies on the RF Elements horns, you will see that there are lots of folks who report amazing results by switching. Cheers! Mike. limited
because of frequency, I really need to be able to handle a couple of clients which could do maybe 200m each with an AP aggregation of maybe 300m or something.
I realise it's probably a pipe dream I am after but thought it worth asking nonetheless :-)
Regards Paul

Hi Paul,
Do you think that the limitations on throughput are due to RouterBoard CPU capabilities, or due to background noise on the operational spectrum?
If it's the latter, perhaps consider swapping your existing AP antennas to symmetrical horns - horn antennas deliver some significant performance boosts to multipoint networks in congested areas for several good reasons - I can't say it any better than Tasos from RF Elements: https://www.youtube.com/watch?v=preGfGrZR-Y
Hope it's helpful,

Hi all,
We currently use a lot of Mikrotik gear for backhauls in a point to multipoint arrangement mostly with some PTP links as well. We do this as we are limited on mast space and frequency as we use the 5ghz band and PMP licensed stuff is really not possible in dense areas in which we operate. We typically bring 1 or 2 fibre connections into an area and then redistribute the bandwidth using wireless, the area is pretty busy frequency wise but we seem to have our network running nicely at the moment. We also operate under carrier licensing and take advantage of the low impact install rules, sometimes we are able to stretch that a little but that also limits what we can put on a roof within reason.
We currently run on 3 frequencies in most areas, usually with a sector servicing the majority of the locations and sometimes one or two PTP links as well, it just depends on the design needed, but usually we can get away with getting to use the spectrum we need.
We are starting to see NBN rolling into the areas where we cover and want to compete with our own network, we have the resources and transit and peering capacities but our wireless gear just isn't capable of delivering the bandwidth we need to aggregated backhauls to buildings that we service.
I'm interested to know how other people manage this, if they have been able to, I am really not interested in providing faster than 50M plans to customers as an NBN equivalent plan, but being able to service just a handful of users at those speeds would top out any Mikrotik radio, especially on 5ghz band, or most radios that I can think of, and apart from running our own fibre or buying more I can't see any options.
If we need to buy more fibre then it shoots our pricing out of reach and it would be a waste of time so I am really trying to find a way to get the most out of our wireless networks as we have quite a lot of locations we service now.
