Re: [WISPA] High Throughput Licensed vs. Unlicensed - change of topic -- customers / AP

2009-04-11 Thread Charles Wu
Even in the most competitive urban markets, if you're selling VoIP + Data as a 
combined offering, I'd bet that your ARPU is at least $200+ / month

Heck, from our experience, we find that voice revenues are generally 2-4x data 
revenues -- so if a business is paying $75 / month for a business connection, 
they will probably spend $150-250 / month on VoIP (for business, say we assume 
an average of $30 / handset -- that's 5-10 handsets)

So, say you have 15 business customers at $200 / month, and 20 residential 
customers at $50 / month for the evenings

You're still @ $4k / AP

Or, since we're ultimately talking channels -- with GPS synchronization, it's 
possible to put a minimum of 2 APs / channel (and if you're on a building in an 
urban environment, you could be stupid like us and put 4 APs on a single 
channel =)

In this scenario, the value per channel of LEGAL high-power unlicensed spectrum 
keeps going up

-Charles

P.S. -- care to share your numbers? I only have personal data to go by...and I 
in range? Or way off?

Hi Greg,

The issue with VoIP over shared wireless is contention for time slots -- which 
translates into jitter and pps

With VoIP is it really a bandwidth issue or is it a latency issue? My  
experience is mostly with Skype and not SIP/H323 but what I've seen is  
that the bandwidth consumed isn't very high but the latency makes it  
or breaks it.

Hi,

I think that's maybe a little high... we have a Canopy AP right now with
100 users on it... about 10% business and 90% residential and it's
probably bringing in about $3,500 / month. We will probably load it up
to about 120 users total, at which point it will be around $4,000 /
month.

20 business customers during the day time (8-5)
60 residential customers in the afternoon / evening (4-12)

However, the discussion has to come back to the reality that we don't 

  
  work for the government (and can't print money or write stimulus bills on a 
whim), and as a result, have to figure out a way to make a buck so we can 
feed the dog, buy gas, pay for those ski trips in Utah...
  
  
That said, we get back to "bang for buck" or "good enough"

True, the PTP600 will generally work for all scenarios, but it's akin to 

  
  killing a bug with a nuclear warhead -- it's a lot more cost effective (and 
there's less collateral damage) if you just step on it with your shoe
  
  
So, for the 1% of times when you need to shoot 50+ miles while bouncing 

  
  off 2 different mountains, the PTP600 will be your best bet
  
  
But for the other 90% of the time, when you have a 10-20 mile shot and 

  
  want something that reliable, carrier-class, and interference / spectrum 
isn't an issue, many are using Mikrotiks / StarOS / Trango Atlas / name 
your own cheap but decent proprietary Atheros-based system out there
  
  
Now, I'm personally extremely cheap, but the argument is over because you 

  
  can't just look at up-front price because long-term cost is just as (if not 
more) important when talking about WISP networks
  
  
That said, being a slow day, it's worth exercising one's mind to analyze 

  
  possible "what-if" alternative situations -- bear with me here and follow 
my logic here...
  
  
The MOST VALUABLE ASSET of any WISP is HIGH POWER MULTIPOINT SPECTRUM
