a lot of great stuff out there. very exciting. addressing the problems wisps face. speed, distance, cost but nothing is being said about our biggest problem, TREES!. is the m series still strictly a LOS? hoping to see some nLOS or even a little NLOS. i've had some luck with ps2ext set 10mhz. disappointing if it takes the full LOS(fresnal) to get any of the benefits

Hello,

As with any 2.4Ghz or 5Ghz device, it still will require LOS operation.

Thanks,

Mike

Sorry to hear that trees are such a problem in your part of the world, but for many others, they are not a problem (although for us they are an occasional problem). Where are you located? Can you use 900MHz (we can't in Europe as it is used by GSM).

Virginia. i tried a tranzeo but didn't to any better than the ps2ext set to the narrow band width

any plans in ubiquiti's future foe an affordable 900 line

I'm sure Mike hears that question every day.

Tell you what though. If they made a 900 mhz unit and priced it at $120 each they would have 50% market share in no time. We have zero 900mhz deployments due to the fact the the CPE are so expensive to build. We would rather do 5 ghz point to point shots to get around stuff to be honest.

But 50% market share of a small market?

yea here in Alabama the pine trees are like little gremlins that feed off of radio waves... (couldn't think of a better analogy).

We use some Vecima equipment. Waverider I think. It's all right, but the bandwidth is pretty low as with any old 900 equip. About 1.5mbps is all you can push through it in perfect conditions. through thick tree coverage 0.5-1.0 mbps isn't hard to achieve, and the use of 900mhz phones is alot lower due to the movement of cordless phones to 2.4 and 5.8. I am personally more interested in where the 700mhz is going.

Price on those eum3005 waveriders USED/Refurb is like $250-$500 sometimes though. Not very good considering internet these days is like ~$30/month.

700 MHz spectrum in the US has some ranges/locations still to be auctioned, hasn't it ?

Outbidding Google, tellcos and cellcos to win it is an exercise left to the reader! :idea:

Not many companies want to put efforts in the 900 Mhz field.

I suppose they wait for the 802.22 Wireless Regional Area Networks standard. It's a cognitive radio standard specially designed for NLOS using the white space recently left available.

Hopefully this will be a future product from Ubiquiti !!!

exactly. the speed is too slow. the price too high. air cards can easily get that now. making it tough to compete.

Try 2.4 GHz or 5.2 GHz with big antennas (24 db for 2.4, 28 db for 5.2). It works for us thru both trees and buildings.

Sorry to hear that trees are such a problem in your part of the world, but for many others, they are not a problem (although for us they are an occasional problem). Where are you located? Can you use 900MHz (we can't in Europe as it is used by GSM).

We have 900 MHz GSM here(.br) as well, but only on 902-915 MHz; 915-928 is allowed for ISM radios. SR9/XR9 have 1 10 MHz channel option(922 MHz) that fits the band, so P2P links or 360 degree coverage are possible.

You cannot do sectors or cell due as only one channel is available... it can be your plan B for NLOS when MIMO, high output power or big dishes all fail. Not good for plan A, too little aggregate capacity. As for the cost, if 95% of your customers use the US$100 solution and 5% of them must use the US$200 solution, that's US$105 average cost per subscriber.
