The only clue in I ever received was from the FCC themselves. When I was doing beta on these units and beta on the 5450AP regular Canopy units I applied for a STA license in that area and in the process of acquiring that one of the agents called me and widened the authoritative area, but told me there was weather radar in the area and which frequencies.

So maybe get a hold of your FCC field agent?

You could park on it with a spectrum analizer for a while and see if you pick up unexpected transmissions.

Have you had any DFS true positives yet? We have a local customer in ATL that tried the DFS bands only to discover there is quite a bit of radar activity here.

Is there some way to determine what areas would have this problem?

Yes, that is 20mbps of shared bandwidth per sector. As others have pointed out, that is the way the internet works. Assuming 4 sectors, you would have 80mbps of over the air capacity at a pop.

It is common to have a committed information rate and a burst rate for a connection. Another way to look at is just as oversubscription. The total capacity that the AP can deliver is 20Mbps aggregate. Then depending on your customer usage habits, you can sell the same bandwidth to a few people and they may never know the difference.

It would have to be a business/high end only setup but the numbers are great for high bandwidth customers. Currently to do a 10/10 and above, we use a dedicated bridgewave 60GHz link. With next day replacement on the hardware your looking at 15-20K for the link. For 10/10 pricing would be in the $1,700 - $2000 per month range. You make your money back and make a profit within the two to three year contract but the margins are not that great. If you could sell the same 10/10 in a PMP setup, you are looking at about $30K for the POP and 60K for CPE and routers for 40 subs paying an average of $1000 per month. Assume roof lease and fixed costs such as bandwidth at 10K per month and your looking at 30k per month profit on a 90k investment which gives you ROI in 3 months. Of course your not going to be able to install them all on day one, but even if you install them over the course of a year you are looking at real profit within the year.

I would much rather run this type of pop then a residential setup where I get calls about someones email not working or their computer won't turn on. For the most part, our business customers understand that we are selling them bandwidth and they don't call unless their is a problem with my network or perhaps some other part of the internet since I get lots of my bandwidth from Cogent. ]]> http://www.dslreports.com/forum/remark,20735848 Thu, 03 Jul 2008 08:56:57 EDT Re: Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20735780 dongato17 : The best bet here would be to have a warranty that covered the leasing term.

Hardly any DFS false positives.
In fact this platform has less problems with DFS than the regular Canopy 5GHz stuff and the Motorola PTP Orthogon radios (less false positives). And this is in our test area with four of the new Canopy 400 AP's, 2 5450AP's and 2 5750AP's directly colocated.

You can sync these with normal Canopy sync methods (CMM, CTM etc) as long as the cable run is shorter. The units actaully need a bit more power than regular Canopy though, so long runs would have to use their new power supply I would think.

Distance for full speeds will vary, but we are keeping it to around 1 mile. We have clients on it out 5-7 miles though.

They take 10Mhz of space per channel, but you can reuse channels back to back in a 4 antenna cluster, so on this we are using four AP's on 20MHz of channel space (two pairs, one pair per channel facing oppsite directions). With this pattern you could get a high density of clients, but you will have to watch your AP throughput of course.

These units will do complete non line of site NLOS at close range within a mile. Speeds drop to something like current Canopy speeds in the 5GHz as a trade off. And by NLOS I don't mean trees really, we are talking city buildings and multipath NLOS.

I think street price is more like $550 per CPE, not $1000.

We are going to continue to use it in dense city areas within a mile to service larger customers and NLOS applications.]]> http://www.dslreports.com/forum/remark,20717781 Sun, 29 Jun 2008 20:11:20 EDT Re: Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20717699 lutful :

The whole cluster wouldn't be on the same frequency. With older Canopy gear you had to reuse frequency but with the 400 series in 5.4 there would be no need to do so. In a radar event, you have 10 seconds to move during which you have 260msec to transmit. This transmit should be move to X frequency. You wouldn't want your subs roaming to another sector as a roam event would result in seconds of down time.

I am working with a $1000 street price for SMs but am assuming you could most likely buy packs for less per unit.
I am running the numbers with 10-20 subs per AP ranging from 2-2 to 10-10. If they were all 10-10 subs, I wouldn't think it would work with more then 10 subs per AP but with 10MHz in 5400 you could double up on sectors to load balance if it got that far. ]]> http://www.dslreports.com/forum/remark,20717193 Sun, 29 Jun 2008 17:40:14 EDT Re: Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20717025 dongato17 : Obviously it is a nice feature, but is synch required for 5.4GHz band when there is so many channels available? Also, wouldn't putting the entire cluster on the same frequency increase the impact on the subscriber base if there was a radar event? Thoughts?

Then what is the street price for the SMs for the 400 series? $900 or so? If you are selling 10/10 (or 15/5) on this system, how many of these subs would you put on one sector?

from what I have read, it uses 10MHz so higher power density and more room to work work around radar issues. It also has a decreased chance of seeing radar emissions or sidebands.

AP pricing seems to range from just under 3K to MSRP just under 3500. For a 360 degree pop our looking at ~12K for the APs, 1K for a CMM Micro + $100 for a 24V PS, Plus wiring, mounts, grounding etc and it is a $20,000 pop (without labor). Add 5K for a used 7200VXR, 1K for batteries and another 4K for other core stuff like the rack etc and its a $30,000 pop. CPE cost is high so it would need to be business accounts paying an average of 1k per month for speeds of 3 to 10m. Works for me if the pps is better then the current canopy gear and I can work around the DFS issues.

I have seen both 60 and 90 degree sectors on spec sheets, at times on the same spec sheet... Some of the case studies on Motos site appear to suggest that they are actually 90 degree sectors.

For our cost structure to work, a new pop needs to be designed for business accounts. A CPE price that allows the addition of residential accounts is nice, because it helps balance out bandwidth demand, but the ability to support business accounts with SLAs is critical.

We are high density so the majority of subs would be within two or three miles. Three miles seems to be the magic number at which we can bring new subs on line at a fast enough rate to justify the cost of capital for the POP. It is also a good distance for good coverage from multiple locations. ]]> http://www.dslreports.com/forum/remark,20715932 Sun, 29 Jun 2008 11:50:00 EDT Re: Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20715911 IntraLink : I think it has been released in the US, but you'll have to ask your distributor.

We like it, it works as advertised.

We use it just like you are thinking, for dense business areas that need more capacity.]]> http://www.dslreports.com/forum/remark,20715911 Sun, 29 Jun 2008 11:43:25 EDT Re: Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20715903 petecarlson : I have been looking at this as well but I was under the impression it had not yet been released for the US market yet. How do you like it so far?]]> http://www.dslreports.com/forum/remark,20715903 Sun, 29 Jun 2008 11:40:34 EDT Re: Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20715876 IntraLink : We are using the new Motorola OFDM PtMP Canopy 400 series.

It gives us a little over 20Mbps aggregate, again with Canopy superior over the air noise tolerance.

So we sell a 15Mbps down by 5Mbps up.

But you could set it to 10 by 10.

The OFDM units handle a bit more oversubscription than the regular Canopy stuff.]]> http://www.dslreports.com/forum/remark,20715876 Sun, 29 Jun 2008 11:32:06 EDT Re: Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20715417 dongato17 : I'm guessing that these are business accounts then? What's the distance for most of these types of links for your market?

We could all use more capacity. I would like to be able to sell up to 10/10 to 10 using 10MHz :) Assuming 2/1 over subscription we would need 20m FD or ~30m HD based on current usage on 10/10 accounts. For this to work in my market, it would have to be non-contention using polling or slots.]]> http://www.dslreports.com/forum/remark,20714224 Sat, 28 Jun 2008 21:27:15 EDT Needing more PtMP Capacity? http://www.dslreports.com/forum/remark,20713997 dongato17 : Who here is needing more capacity with their PtMP system? Or are current systems offering adequate capacity? What is the limiting factor here (backhaul links, cost, customers don't want/need more speed, your connection to the internet, etc.)?

I'm interested in hearing some discussion on this topic. :)
