Using Bullet M as Backhaul

[wispwest]

Can anyone list any ups/downs as using Bullet M as a major backhaul? We currently have real backhaul Trango T45's that are getting overloaded, I think this would be a good speed upgrade. My only concern is RELIABILITY. We pay big $$ for real backhauls that have near 24/7/365 reliability. My boss does not want to pay over $10,000 for 100Mbps backhauls such as Motorola PTP, Orthogon, dragonwave, etc.

I want to suggest this, but at $79/ea, he might think this thing is some cheap crap that will break down! so its....

$10,000 / or $79, that's a big difference!

My experiance is that any wireless systems reliability
is directly related to the skillset of the persons setting it up
more than any particular brand name

While you can not really compair a set Dragon Waves or Orthos
(which is now Motorola btw) to a set of m2s
There is some very proprietary mechanisms in any of those choices
that make it an apples to oranges type deal but that said

a set of m2s in skilled hands could rival either in terms of reliability and come close in performance
as for matching their full duplex throughput .... not yet ...
but perhaps could soon ;)

For the price tag shurly the boss could justify
spending a few bucks on a test
little to loose and alot to gain :)

Thanks! I guess that makes sense. I just never understood why a brand name would cost $10,000 more, I could imagine some, but not THAT much. Then of coarse, that's probably what the cellular carriers use for backhauls. I've been in some Alltel tower shelters and seen Tsunami branded backhaul for their 3G EVDO equipment

My 22 mile backhaul as been extremely reliable with a consistent 58.6 Mbps TX and RX data rates as measured at the station end.

Brand name products like Motorola PTP600 use faster processors, very good firmware, and can deliver 300Mbps in a 30MHz channel. They can also operate in a high-noise environment well. Canopy for example, can function with a s/n of 3dBi which most systems would choke at. Licensed radios are a whole different ballgame although we sell a licensed radio that can deliver 100Mbps full-duplex for less than $10K. Trango supposedly has a similiar product with even more bandwidth.

Given that, the question then becomes, can a lower price radio function well for the cost savings? That answer depends on the environment. In most cases, it's not an issue. In some cases, it's not possible. However, in some cases, $15K for a 300Mbps radio isn't feasible either. Just look at municipal WiFi and you can see that $1500-$10K AP's killed that model. In that case, an $80 radio could make a huge difference. We have built designs based on that premise.

So, in summary, could a Bullet 5M replace your 100Mbps links? If the link can run a 40MHz wide channel, has excellent s/n ratio, and has little or no interference, then you will get a usable 80Mbps average half-duplex, low-latency link (sub 3 ms for a few miles). If that is sufficient, the answer is yes.

Couldn't Help myself :lol:

Can't wait to try out the Bullet M's

Allow me to quote Mike Ford.."Ouch"

Stormed most the night. Wind was blowing the rain so hard, it was coming under the window sills. Had 3" of rain.

TX/RX held at 58.5/58.5

That was funny Wifi442. We did some testing today and at 50Mbps, the computers gave up feeding them. We are restesting tomorrow with Gbps network cards feeding the switch which then feeds the radios. It looked like the file went to cache and then couldn't deliver that data as fast as necessary.

That's what happened to me over the weekend. I didn't know the FTP server was running SQL server in the background.

How about a screenshot of some of these numbers? Come on, talk is cheap... Let's see a screenshot of 50mb/s tcp traffic across a 6 or greater mile link.. Please?

All I did was make one an AP and changed my IP settings, channel, power (took it down one dB) and ACK. Everything else is at default. Tweaking anything else didn't make much difference or made it worse.
