Matt brings out a good point that shows the benefit of PTPs and Syncing
feature of Canopy.
I don't deny these advantages, and they can be beneficial in many cases.
However, don't forget that your equipment costs go up at more than double
per new customer compared to PtMP deployments where each new customer is
jsut a CPE.
PtP model, each new customer is 2 grand. (canopy)
PtMP model, First customer is $1500. (Trango)
PtMP model, each new customer is $500. (Trango)
And this is BEFORE you consider roof right fees. I'd rather pay $200 per
month for 1 AP antenna than 5 AP/PTP end point antennas.
One of the biggest advantages of Wireless si the abilty to oversubscribe and
resell unused capacity. Few people use their capacity.
PTP deployments prevent that.
There are arguements that in the long run, the PTP could be preferred for
avoiding remote interference, or higher capacity for the end game.
But from a startup and profit point of view the PtMP method offers a clear
advantage, and reduces risk and/or long term liabilty if leasing.

You don't need connectorized backhauls. The sync functionality alone
allows you to densely colocate backhauls. We've had as many as 5 Canopy
backhauls mounted within feet of each other all operating on the same
channel.

It's theoretically possible to engineer up to 8 equally seperated

you'll find in the Canopy manual :-)

Matt,
How do you fit more than 10-12 of those type of dedicated links on a
single tower?

We rarely use multi-point systems for customers and when we do they
are either small businesses with very little voice and data needs or
they are just data customers. All of our customers with any
significant amount of voice are running on dedicated radios. I would
say our average customer buys 12 lines of voice and delivering that
over a Canopy backhaul works just fine.

So you agree then that being able to do VoIP is key. I'd like to hear
more
about your experiences with VoIP. Is your solution actually doing it
well or
is that your idea of doing VoIP well is 8 only concurrent calls per
sector
so long as the quality is decent for those few calls? We have talked
to many
very users of other common 5GHz brands these past few week and we
have been
consistently told that performance is just dandy until you bump up
against 8
calls. That is a less than 50 call per cell limit, which does not
seem like
enough to justify the investments needed on the NOC end for the
softswitch.
How do you define good VoIP performance Matt?

Matt, to further your comments that you see WISPs providing layer 2
transort
for carriers.
We have multiple CLECs and non-CLECs buying layer 2 transport from us
now. All are used to buy alternative access from fiber providers and
therefore fixed wireless was a naturally next step. Further, almost
all indicated they would have done it sooner, but the fixed wireless
companies they approached weren't willing to offer them layer 2
transport.
How about VoIP? How many of you consider VoIP to be an
important part of your service future as a WISP? If so, how do you
plan to
support since it cannot be done decently with the other popular 5GHz
solutions. That's not my opinion so much as the opinion of many
larger
Trango and Motorola WISPs I have been talking to lately.
We are doing a significant amount of VoIP now. We have VoIP customers
running on top of both Trango and Canopy radios. Canopy is a
significantly better solution for VoIP since we can properly
prioritize voice with Canopy, while we cannot with Trango. We also
wholesale VoIP to other operators and help them --if they require
it-- with getting their network ready to support VoIP.
If a key goal of WISPs is growing ARPU, what are WISPs plans for
doing that
with whatever your current technology permits?
I believe VoIP is the number one way to grow ARPU and the fact that
we bundle VoIP is why I believe we have one of the highest ARPUs in
the industry.
