Our plans are to have up to 10000 residential users in a city of 700000 people. We have 17 clusters in the moment, about 80 APs. The easiest way I see it is to double the numbers of APs. We have available 11 non overlapping channels on 5.4 Ghz.
Any thoughts ?
Thanks
No reason it can’t be done. Motorola does give tips on collocating multiple clusters - frequency plans, timing, and such. You will definitly want a CMM on each cluster.

With the other tower sites in the area, you might be pushing it.
Can’t use another frequency?
It’s legal only to use 5.4 and 2.4 Ghz. On 2.4 its owercrowded. We are backhauling also at 5.4. The plan is to run the backbone on liceced band, or FDDI.
We will use some of the hidden frequencies for high demanding busines users.
What’s bothering me is how many costumers will go down when we turn on the new APs.
I assume 900 is also not allowed?
No, it’s not. In Europe 900 Mhz is used for GSM networks.
Should be an interesting engineering and design effort getting all those AP’s running in 5.4.
this is a stupid question but no 5.2 or 5.7s?
the real pain of using multiple freqs. is keeping a good stock and making huge purchases to get the bulk discounts.
It’s not legal. Even if it was 5.4 is better, look what frequencies I can use on all my radios:
5470 5475 5480 5485 5490 5495 5500
5505 5510 5515 5520 5525 5530 5535
5540 5545 5550 5555 5560 5565 5570
5575 5580 5585 5590 5595 5600 5605
5610 5615 5620 5625 5630 5635 5640
5645 5650 5655 5660 5665 5670 5675
5680 5685 5690 5695 5700 5705 5710
5715 5720 5725 5730 5735 5740 5745
5750 5755 5760 5765 5770 5775 5780
5785 5790 5795 5800 5805 5810 5815
5820 5825 5830 5835 5840 5845 5850
Legal is form 5495 to 5705.
With that amount of channels you should be good to go. However I hope you are not planning to have 10,000 on 80 AP’s thats 125 per AP,
you will seriously be pushing it and performance will be poor.
What bandwidth will you be giving to the customers.
Do you want to run VOIP or high priority channels for QoS
by the way what is the area size you want to cover…

It's gonna be a chalinge.
Can you guys recomend some software for frequency planning?
Till now Google Earth was enough for me. I'm reading trough snmp rf frequency carierr and number od registerd SMs, results generate transparent png wich is placed on the map in direction wich AP is facing.

One thing you could consider doing is using some of Wireless Beehive’s new polarity conversion equipment. It is a passive device that allows you to switch from vertical to horizontal polarity. You can then use the channels in the middle of the 20 mhz separation you already have for your first cluster. The only downfall is that you then need a vertical -> horizontal conversion device for every SM which costs about $50 each.
If you’re looking for a “free” freq/coverage mapping program, there are many fans of RadioMobile in the Canopy World. It is written in Km instead of miles (which I would assume is ok if you’re using 5.4).
Though it is not intuitive the first few times you use it, if you Google “Radio Mobile” and “tutorial” you will find some sites that help you out.
If you’re in the market to spend 10,000 euros or more, then your product choices increase!! 
Note the CMM/Synchronization comment above. if you are not synchronized (one of the chief benefits of a Canopy system) then you will have packet loss (at a minimum) all the way up to de-sensing of radios…
HOWEVER, when you get this done, we would LOVE to see a picture of your tower(s).
Good Luck!!!
We will have about 150 to 200 AP. All sites have CMMs, and they will have two if nececery.
Question: Does two CMMs at same site generate exactly the same pulse?
The area is about 50 km2. There is a mountain near the city, we have full coerage from there, 3 clusters. The other clusters are on the highest buildings and hills. Problem is that we have 500 CPEs on the mountain and the chalinge is to have as possible small number of users wich will stop working when we turn on the new APs.
Bandwith for the customers will be 512 down 128 up. Limit is 10 GB. Average per user in the moment is 5 GB. We will run VoIP with devices wich are capeble of vlan tagging and pppoe, like Sipura SPA2100.

Would an SM not work on Horizontal by installing it sideways ?
Good news: two CMMs will sync the same…this is true for intra-system and inter-system.
this is one of the not-well-known secret benefits of Canopy…
satseeker1: My biggest concern installing sideways would be the integrity of the case in weather. Otherwise, from our experience it should work…
Do you know where I can find info on this converter? Will it work on 900?

I agree fully. Have to sell a roll of tape with each install to seal one up? :lol:
