Patrick,
I'm talking about ALL
the CPE on a sector being able to send its que'd voice out before any
CPE can release data into the sector?
Thats pretty cool. But I'd be interested in learning more on how that
protocol method interacts with bandwidth allocation per subscriber.
This is the problem that I see from the provider point of view. They have
two profiles of subscribers, the ones that use their bandwdith, and the ones
that don't. The ones that don't can be oversubscribed heavilly, therefore
can be sold to at a much lower cost to compete agaisnt commodity cable and
DSL competitors. The ones that do, monompolize the network, and need to be
sold to at a higher price, often designated at a business class CIR type
service, or however else the ISP tends to market the hgiher QOS guarantee
service. When the ISP qualifies the prospect appropriately in advance
correctly, everyone wins. The ISP gets paid, The High QOS client gets the
priority he needs, and the low cost client does not get starved of
broadband. The problem occurs when the ISP does not qualify the prospect
appropriately. We've learned that every client starts their conversation
out, "I barely use bandwidth. I just need a very low cost service like ADSL
for $49. I'm just doing VOIP, basic Internet use, and creating a VPN between
my offices for a central file server. Maybe some occassional video
conferencing. But nothing demanding." Or they lie, and say they have one
computer just doing limited internet browsing, and you learn they are
hosting about 20 web servers and a search engine, or a Bulk Email service.
Or if I make it relevent to this thread, they end up putting 20-30 VOIP
phones on the service, that they say is just a limited web browsing service.
The truth is Managed VOIP is the big bnadwdith hog today. So globally
Giving VOIP users first priority over all other traffic could be a big flaw.
It would allow the one that misrepresented their need to chew up all the
good honest customer's bandwdith. Meaning if VOIP had first priority above
all data traffic, the Client paying $49 a month and inappropriately putting
30 VOIP calls on the service, would have better service than the other 20
customers paying $200/month for data services that bought the appropriate
bandwidth for their need. So their is a catch 22 on Prioritizing VOIP above
all.
So the question is... Does Alvarion do anything smart about this, to deliver
a fair amount of bandwidth to ALL subs, when prioritizing VOIP?

I don't think so Gino, but I'm open to be proven wrong. Tell me who else
can actually prioritize over the air sector wide. I'm talking about not
just pushing out the voice first on any given CPE, I'm talking about ALL
the CPE on a sector being able to send its que'd voice out before any
CPE can release data into the sector?

Subject: [WISPA] churn,double play and why WLP is key - I finally
understand
it
...So I'm here at our annual national meeting and our project manager is
explaining the Wireless Link Prioritization feature available for
BreezeACCESS VL. Frankly, it has always seemed esoteric to those of us
non-technical types, but now I got and it is simple enough.
First, I learned the statistical improvement in churn when a provider
has double play VoIP + data customers. We have had a few CLECs report to
us that with a single play model their churn is about 9%. Adding double
play takes it down to close to 1%. This is critical to the business
model because they said a 10% reduction in churn translates into about a
20% improvement in NPV per subscriber. That's obviously huge. So what's
the WLP feature available in BreezeACCESS VL have to do with any of
this?
BreezeACCESS VL can already do QoS priority tagging of packets per CPE
using layer 2 (802.11p), layer 3 (IP TOS, DSCP) or layer 4 (TCP/UDP port
ranges common with Cisco, for example). That's good and already better
than most brands of BWA gear. BUT, that's only PER CPE. In a typical
situation, this does not help at all when multiple CPE are on a sector
-- there is no prioritization at the RF level in unlicensed from any
brand...until now.
WLP (also called multimedia application prioritization) actually solves
this and enables over-the-air prioritization for the first time in the
industry. The translation for this is that BreezeACCESS VL can now
deliver massive VoIP, up to 288 concurrent calls per sector with a MOS
(mean opinion score - a rating of voice quality) of 4.1. That's a
phenomenal quantity that is more than 10x our main competitor as spelled
out in their own relevant VoIP document.
So why not just use VL with firmware version 4.0 without getting the WLP
feature? The WLP is the key to get the quantity AND THE QUALITY of
service since it reserves air priority for the VoIP. So, in a double
play business model, it is essential to get MOS voice quality of at
least 4.1 and even 4.33 you must implement the WLP.
I believe it can now be said without reservation, that if you are using
unlicensed and wanting to implement a double play of VoIP + data, the
ONLY product out there that can do it in scale and with toll quality is
BreezeACCESS VL.
