Travis It has been great to see how you have turned into seasoned Canopy provider .... SO i must assume your opinion of the product has changed recently...

We will probably load it up to about 120 users total, at which point it will be around $4,000 / month. Travis Microserv Charles Wu wrote: Which begs an interesting point -- how much revenue / AP? I would think $5k / month for a 20 MHz chunk of 5.8 spectrum, while a bit on the higher side, isn't an unreasonable goal Using Canopy...you have 14 Mb aggregate Selling for $50 / month residential -- that's 100 customers sharing 14 Mb Splitting between $100 / month business and $50 / month residential (for better traffic shaping) -- that's now 20 business customers during the day time (8-5) 60 residential customers in the afternoon / evening (4-12) Now obviously, there will always be places where you're shooting into a hole, or there aren't that many homes / business being covered, blah blah blah blah -- but I don't think $5k / month / AP is an unreasonable goal Thoughts?

I'll just add that while we are trying to keep the numbers trained to a common wisp - either you guys have a lucky horse shoe or achieving a $5000/mo revenue on one ap is a bit outside the avg... At least for discussion sake. But - even at 1/5th of that your argument still holds true for the most part. Its just that you add in 900mhz (not as common) and all the lower power 5Ghz spectrum available now, 2.4Ghz etc and also mention you can run MT stuff on 10Mhz channels and you just effectively doubled your options based on what type of clients you are servicing etc... Then theres radios that have GPS sync for spectrum reuse etc and the conversation starts to get a lot more complex :) But, in any case this has been an eye-opening discussion...

I've got a 35, 45 and 65 mile shots with StarOS and they work just fine but only put out about 18-25meg at those distances. That's enough for me, but I can see where you would want more capacity and I suppose that within that narrow definition, a PTP600 would be better than a licensed link. Make no mistake, the PTP600, even though it's almost 5 years old, is still one (if not the) best UL radio on the market from a pure technological perspective -- no other radio has it's combination of 1024FFT OFDM, Space-Time-Coding, MIMO, etc Makes you wonder what planet Motorola / Orthogon raided to get the engineers who built that radio =) And I'm sure many on the list can attest to the wonderful things that a PTP600 does / can do 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 (b/c ultimately, it's the only thing that generates revenue, and like it or not, the #1 determinant in valuing a WISP, or any business for the matter, is EBITDA) In optimal conditions, there's 125 MHz of clean spectrum (6 channels) Assuming you can make $5k / month per AP (or channel) -- as spectrum gets limited, the decision will ultimately boil down to 1. Pay $2k for a cheap Atheros based backhaul to bring 30 Mb to your tower and lose 1 channel (or $5k / month in revenue) 2. Run that backhaul in turbo mode, get 50 Mb at your tower, and now lose 2 channels (or $10k / month in revenue) 3. Pay an extra $10k for a LICENSED BACKHAUL that frees up more spectrum for multipoint, and never have to worry about interference on your backhaul ever again -- and make an extra $5-10k / month b/c you can add more customers on your tower Some food for thought =) -Charles ------------------------------------------------------------------------ ---- ---- WISPA Wants You!
