Folks, IMHO, It really comes down to a cost benefit analysis.
So an 802.11 or canopy system might run you a lot less CAPEX, but it carries more OPEX. So if in a given tower site you pay 200 / mo per antenna deployed on a tower, wimax might be cheaper than a lower system that cannot scale to say, 100-250 subscribers effectively. In addition to backhaul costs if you go carrier class. So lets break down the real costs: Cell radius= 30km Wimax Sector, carrier class: 7,500 ( 20k ) on a lease of 36 months, 750 per month PTP licensed radio: 12,000 on a lease of 36 months, 500 per month. Cost per subscriber: 299 (150 after install paid by customer ) ARPU per subscriber: 60 ( voice + data package ) Lease per tower, 3 sectors+ backhaul and : 1000 Total subscriber count per tower: 500 ( 5 month build out, 100 subs per mo ) Calculate it out and you show 270k in annualized revenue for 1 tower site, that can easily support this model for a basic internet plus phone service with no hiccups, and likely still have capacity left up to 750 subs on 3 sectors. Yes the rules of oversubscription apply, you cant sell 750 business grade circuits. The point is for a TCO, that's one tower site to cover a 20km radius, meaning less leases per month of 1k or more, so isntead of 4 tower sites to cover this area ( and pay 4k per month ) If you are just calculating your break point on your tower costs, you break even at a 100 subs per month click, at 3 months in. On your subscriber stations, if you carry the cost, it takes 6 months per subscriber. However on a 12 month basis you are @ 270k with 170k in cost, or 100k in profit. MOT canopy example Cell radius= 10km Cascade networks canopy system: 3 per tower, 9 sectors: 2500 x 9 = 20,000 PTP licensed radio: 48,000 on a lease of 36 months, 3000 per month. Cost per subscriber: 250 (150 after install paid by customer ) ARPU per subscriber: 30- data only package Lease per tower, 3 sectors+ backhaul and : 1000 Total subscriber count per tower: 150 ( 5 month build out, 100 subs per mo ) Tower sites: 3 Revenue per MO @ 500 subscribers 15,000. ( 150k a year in revenue ) So since you cant really effectively provide carrier class voice you sell only data. To cover the same area with 1 tower it takes you 3 towers which triples your OPEX for towers and triples the # of base stations needed, as well as triples the backhaul costs, while impacting where you are with your revenue. - Jeff -----Original Message----- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Matt Liotta Sent: Wednesday, April 22, 2009 11:02 AM To: WISPA General List Subject: Re: [WISPA] 3650Mhz and Wimax Vendors Those of us operators who actually have experience in the field with the gear tend to avoid posting to threads about WiMAX because the threads quickly devolve. I suggest you read the archives of this mailing list. To summarize though; operators who use WiMAX like it and think the technology is actually different and better than what else is out there. The people who don't use WiMAX think it is overpriced and not particularly interesting. -Matt On Apr 22, 2009, at 1:41 PM, Charles Wyble wrote: > I'm looking for more operational experience and end user experience. > Certainly good technology contributes to that, but that isn't my > primary goal. > > > Michael Baird wrote: >> It was interesting, but I was hoping for some more first hand >> experience reporting.
