OK, talking about all of the ways that Trango has to fine tune the radios has me thinking.

I've got two systems that I'm having some trouble with. Both are low to the ground and I'm sure I'm seeing multipath. GREAT speed tests radio to radio but poor data rates and high error rates (5% most of the time). Still much better than the wifi it's replaced but it needs to be better.

I don't know the cli on these radios and don't have the time, desire or need to learn. I do need some help from someone that knows them insideout. Anyone need an hour or two of consulting to help me get these two systems polished up so that they run at full speed?

thanks,

JohnnyO,

When you can tell me you've installed In this type of noisy environment

Of course every environment is different. But We have with great success with Trango.

Try colocating right next to qty 5 - 929Mhz 500 watt OMNIs, and the same horizontal plain in Urban america with -60db RSSIs from them, -30db RSSIs on the top channel.

Feel free to share one technical reason why the Canopy is capable of dealing with interference better than Trango. (other than personal experience, because that can not be verified or accurately debated). My guess is in your environment, you weren't taking advantage of Trango's flexibility and using the best polarity for the job. I find most noise, such as from SCADA systems, are on verticle polarity, very easy to combat with a radio like Trango that supports horizontal pol antennas on the fly. You probably were using omnis or testing with Trango default antennas. Try matching up Trango w/ Tiltek Horizontal sector w/ their convenient ext antenna port on all APs and CPEs capable to add narrow beam Yagis.

Trango has 3 ways to combat interference. 1- dual pol switchable, 2- dynamic leveling to compress out noise, 3- ARQ

The choice for 900 Mhz radios is florishing right now, all very high grade radios (WaveRider, Alvarion, Tranmgo, Canopy, AirSpan, WaveIP). All have their own little unique benefits that make them special. Alvarion- Mobile. WaveRider- Dual Polarity Diverity. Trango- Dual Pol switchable + ARQ + great diag tools. Canopy- easy interface w/ diag statistic for Jitter and such.

But as far as surviving noise, not confident that Canopy shines in that territory above Trango. I just don't believe it.

How do I figure ? Trango never worked here - Alvarion did for a lil over
a year - WaveIP didn't work - WaveRider didn't work - Canopy is the ONLY
platform that will work here.

We're using sector antennas and using the water tower as a shield for
the 100s of 100watt scada systems just 5-10 miles away from us......
When you can tell me you've installed In this type of noisy environment
with your Trango, I would be very very eager to listen.

How do you figure?

Our tests have shown that the Trango outperform the Canopy in noisy
enviroment based on its built in dynamic leveling to compress out noise.

The advantage of the Ubiquiti 900M, is its ease to add to an existing
WRAP
or Mikrotik AP, for a relay radio / cell extender.
For example, 5.8 or 5.3 to the neighborhood court, and then 900Mhz for
indoor CPEs located on the court.

But Ubiquiti is not the only radio manufacturer with a plan up its sleve

similar.

Hate to say it Dan, BUT - Trango and Atheros get's it's ass kicked by
Canopy - Canopy is the ONLY 900mhz Platform that will work for us in a

-55 to -60 noise floor situation - so hopefully - you live In the
perfect world and can run "noise/interference" free :)

This is awesome, I knew this was coming, ideally once it works with MT

with adjustable channel width (ie: 5mhz or 10mhz) - you should be able

to push some serious throughput on that 5mhz channel compared to the
existing Trango & Canopy 900mhz systems

Hopefully the pricing on the radio is the same as the sr2/sr5

Omfg.  That's awesome.

Since it's standard Atheros, wonder what the chances of getting it
integrated into Mikrotik quickly are ?

Brian

Just and FYI Demarc has know about this for some time and as soon as
its ready to go we will have CPE and base units that will support it.

The CPE will come with 10dBi or 12dBi options as well as the 250mW or

1 Watt output options. While not locked down we should be able to do
4, 2 or 1 OFDM non overlapping channels which can be used for either
CPE or backhaul designs. The units will also have polling to get the
most out of the 900Mhz band. Also pricing is not set but we are sure
it will be less then anything on the market today with more options,
we will have to wait and see :)
