[WISPA] 3.65

2008-11-03 Thread Travis Johnson

Matt,

I agree. We are looking at the same thing... putting up some 3.65ghz
AP's on our "bigger" towers and moving heavy usage customers to that.
However, until base stations are less than $8k, the WiMax people can
keep spending money on advertising, trade-shows, etc. telling us how
great they are, I'm not going to buy.

When you can buy a licensed microwave radio link for $8k (less
antennas), and you know the company is making money, there is no reason
3.65ghz base stations have to be $8k+.

Hopefully at some point, they will wake up and realize there is an
entire market they are missing.

I'm with Travis on this, with the exception of using StarOS instead of
Mikrotik. It is nice to have a set of standard, mature tools such as
radius, cbq/iptable rules and standard, non-vendor specific hardware to
work with instead of having to use a limited, proprietary system limited
to a single vendor. I've deployed/consulted on 802.11 a/b/g networks
representing 8000+ CPE units and it can be made to work just fine as
long as it is managed properly. Travis is a pro, and he has the
experience to design his network in such a way as to maximize the
performance of his equipment. There are many others out there having
the same success.

FWIW, I believe the most logical next step is to start moving heavy
usage customers over to 3.65 WiMAX gear starting next spring. I think
we are near the threshold of what is going to be possible with
unlicensed equipment - barring some kind of amazing breakthrough. I
foresee a need to deploy smaller and smaller cells to maintain the
desired performance level. It helps to have 10mhz channel sizes
available to maximize the utilization of existing spectrum, but even
that is starting to get awfully crowded. Whitespaces sure would help.

I spent the last two years putting up 802.11a based APs across my entire
service area and migrating customers from 2.4 to them to get the higher
ARPU from faster speeds and VOIP service. I foresee spending the next
two years deploying licensed backhauls and 3.65 APs starting with the
high traffic areas and working out to the fringes. Its the neverending
story.

Hi,

We don't use DHCP. Every single customer gets a real, static IP address.
We also a assign a static IP address to every radio (for management).

When I posted the question a month ago about how to force an SM to
connect to a specific AP on a tower, the only answer was "color code".
This isn't really an option, as that means the installer has to change
the color code in the field. All of our current radios are setup and
ready to connect to ANY tower and ANY AP on that tower without the
installer doing anything in the field.

And how does first level tech support even find the correct radio in the
AP list for a customer on the phone? They have to scroll through 160
people to find them by MAC address?

Yes, Canopy is a slower radio in today's world. 14Mbps of total
throughput on a 20mhz channel is SLOW. Using Mikrotik I can get 30Mbps
(double the speed) on the same channel size. Or I can use a 10mhz
channel and get 15Mbps. And all these speeds can be delivered via upload
or download or any combination, I don't have to set a specific
percentage of up/down.

And how do you guarantee 7ms latency? What happens if a customer gets
8ms? And how do they test that measurement? And what happens when a
customer completely clobbers an AP and 160 customers are getting 20ms
latency? Or you have interference from a new provider and all those
people get 100ms latency?

All of the complaints are easily overcome with the proper management software, DHCP reservations etc. You can easily force the SM to connect to the exact AP you want a couple different ways. And there are several non motorola software packages that do this kind of stuff. We have 5000 subs on it and we don't break a sweat in managing any of this.

We put 128-160 customers per AP and they all still get 10.2 Mbps burst. Slower radio? That seems pretty fast to me.
And we guarantee latency to 7 mS. Hmmm, that is pretty hard to do with anyone else.

We've tried Canopy... twice in fact... once about 3 years ago, and once about a month ago. We just can't make it fit into our network management (IP database, Call tracking, customer management, etc.) system very well... having customer radios that change their LUID and IP address every time they register, having to set the bandwidth on each SM instead of the AP, having no security or ways to control which AP a customer connects to without having to buy their software, etc.

All that, plus paying MORE for a
