So I have 2% of my customer base that is running 900mhz PMP100 using 11 different access points. I am trying to cost justify weather it is feasible to upgrade them to PMP450i-900mhz. I am using a lot of Omni's with the PMP100 so most likely I will need twice as many AP's as I currently have because they won't all be on the same side of the towers. So looking at costs I see the following:
PMP450i AP's x 20 = $46,000 900mhz sectors x 20 = $6,320 PMP450 SM x 20 = $4,784 SM antenna x 20 = $1,424 equipment cost total = $58,528 plus my time of putting it all up I am currently grossing $934.00/month from the 2% of customers running on the PMP100-900mhz now. At this rate it would take 5 years to break even on deploying the 450i-900mhz and I really can't offer any better speeds with it than what I was able to offer with the old FSK 2.4/5ghz stuff. Is it just me or does this not make sense worth deploying?
