Patrick,
I have to agree with you that is some exciting data.
However, I don't want the world to forget one of the core reasons to chose
Alvarion.
And it has nothing to do with new features. The abilty to have higher
capacity links (14-24 mbps real), using OFDM, and being able to pull off the
links because it has a high quality/high gain/low maintenance/Easy-to-Mount
CPE antenna option. And VLAN at the CPE. The efficient packet per second
data of 4.0 firmware of course is enormous for VOIP. 10Mhz channel options
to help make up for single pol inflexibilty. Those are some of the reasons
we are looking to Alvarion this year for expansion in areas where we can
survive with verticle polarity only. Its a combination of all these things
that create the value proposition.
What I will say is that Alvarion is NOT the only manufacturer out there with
some new VOIP enhancements about to be released to their radios. VOIP is
becoming one of the most important criteria to support on wireless
effectively. Vendors will need strong VOIP support to stay competitive. But
Vendors will not be able to compete on the VOIP features alone. Vendors
will compete by being able to offer the most complete solution of many
required features.
The 4.0 Firmware was exciting to hear about. But what I'd really like to
hear about is that new low cost CPE or CPE price reduction that has been
rumored the past few months.

6K
So I have more data for you Matt I just received about what firmware 4.0
delivers in terms of frame sizes and what it can mean to the business
case.
Remember, this is multipoint, not PtP. All Mbps numbers are NET
throughput:
Frame size Upstream Mbps/FPS Downstream Mbps/FPS
64 32.18/47893 40.29/59952
128 34.7/29308 43.79/36982
256 37.68/17065 45.03/20392
512 38.41/9025 45.51/10693
1024 37.02/4432 44.82/5366
1280 38.93/3743 45.99/4422
1518 36.69/2982 44.63/3627
This is a dramatic improvement, first in terms of net throughput the
numbers
are huge and I am pretty sure no other PMP system can get close to them.
But
the main accomplishment is a total leveling of capacity regardless of the
frame size. This results in much higher predictability and ability to
capacity plan. This takes net throughput over 700% higher using small
64bit
frame than the previous version. Frankly it really is an exceptional
achievement that will enable operators to offer very high value services
even to large enterprise. With this version of BreezeACCESS VL an operator
could sell an 8 voice lines/6Mbps of data to 20 enterprise customers in a
single sector with a 5:1 over subscription with a voice MOS of 4.0 or
higher. And with a SOHO type service like 2 voice lines and 3Mbps of data
you could have 160 customers PER sector at a 20:1 over subscription. That
will produce some exceptional ARPU.

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.
