Re: OMGfast.... Looking for review
Re: their using different technologies other than MVDDS for the downlink...
1. WiMAX - Slow. You've seen what it can do on uploads. Multiply that by three or four for download speeds, if that.
2. LTE - Not available for the spectrum Clearband owns, and no spectrum is available to buy at this point that supports LTE. Even if it were, the spectrum would be too expensive to deploy speeds, without caps, comparable to what they're doing now. Plus, I haven't seen an LTE fixed terminal anywhere yet, and that's the only thing that would give you better range than the current MVDDS system while still having any sort of capacity. You would need a 10MHz channel at least for FD-LTE, or spectrum usable to TD-LTE, and the former is tied up by AT&T on 700MHz and the latter by Clearwire on 2500MHz.
3. WiFi - It's a good option. Not so much on 2.4 but 5GHz would work. 2.4 has too much interference in a flat place like Florida. 5GHz may not be much better though. The result: you'd end up with, at best, the same speeds as you get on MVDDS at the same distance, but using cheaper equipment and unlicensed spectrum (unlicensed may have reliability issues). Getting even 80 Mbps of capacity out of a single WiFi channel (20MHz wide...40MHz is a bad idea for point to multipoint due to signal-related issues...so your air link rate is at best 130 Mbps with a dual-polarity antenna at each end of the link) is iffy in PtMP over long (more than a mile or two) distances.
Hence Clearband's choice of MVDDS, particularly since they own that spectrum anyway...and they own more than all 2.4GHz, 5.8GHz (longer-range 5GHz due to FCC requirements), 700MHz, Cellular and PCS spectrum combined...for all carriers...and nearly as much as all of the above plus AWS. To put things into perspective, Clearwire, which says it has a lot of spectrum (it does), has less spectrum than what's available in just the PCS band.
