The cost of equipment depends on the installation. If we use Ubiquiti sectors and CPE's, the sectors run about $500/each and each CPE is around $130. I don't think we have a sector with more than 6 clients on it and I don't think I'd be willing to put more than 10 on one, depending on the channel and signal, each antenna has around 250 Mbps of capacity. So if we have 6 clients on a sector, that's about $213/subscriber.
Most of our business customers are on PtP radios. I use Mimosa B5-lite's for those, which are $300/set.
Some of our customers are in properties in which we already have equipment, so the cost there depends on how many customers are in the same building. I'll typically run the CPE to a switch and then branch out to customers from there. Let's say that the property has 3 subscribers and I used a Mimosa B5-lite to the property. Add $300 for a switch and we're at around $200/subscriber.
I'd probably say that a client, on average, costs around $250 to get setup.
Every antenna and switch in our PoP is connected to a UPS system; I have one large 3U UPS and a few stand-alone desktop UPS's. They probably total around $2,500. We use a small fraction of our available bandwidth; that's not a concern. What is a concern is the spectrum available per antenna, which is why I said I would not put more than 10 clients on an antenna.
I'll write another post about the cost of fiber.
I look forward to the fiber write-up.
If all client stations have good, clear signals, the latency is around 1-2ms. But that can spike quickly if you're dealing with interference or other causes of low SNR.
