    A cell that has only 4 times the radius of WiFi (I assume 2miles/3km) cannot be economically deployed to cover the middle of nowhere.
    That radius covers approx 10sq miles. CONUS has 3.8 million sq miles.
    That would mean approx 380,000 cells, all with fiber optic (wireless back-haul will suck) and power connection to them.
    IMO this just wishful thinking.

    It will be used for diversification where existing bands are congested already, and inside the buildings, that's where investment will make sense.

    I believe the deployments will be similar to LAA, just with better propagation. I’ve seen LAA push out to about 100 yards , so expect CBRS to go 300-400 yards.

    Hopefully T-Mobile actually ends up with sprint then they probably won't participate. But looks like Charter and even Amazon are thinking about participating and of course well known spectrum hoarder Dish.

    There have been tests of CBRS reaching as far as 8 miles line of site and 4 miles non LOS.

    That's with the unlicensed power.
    I assumed the 2 mile with the licensed power level. Anyway IMO is ridiculous to hope that carriers will hurry up and deploy CBRS in the boonies just to... do what?

    Well I look at it this way . It would be wise to deploy CBRS RRHS in rural areas because the auction is less than a year away. Then once it’s finished the deployments are already completed.

    Yes if T-Mobile merges with Sprint they will have plenty of capacity. I could see At&T and VZ getting into a bidding war. That licensed portion will work for the macro networks

    Att and many WISPs are planning on using CBRS for fixed wireless in rural areas. They consider it to have a good combination of propagation characteristics and capacity for that purpose. Everything I've heard from Verizon execs suggests that they're focused on the small cell applications.

    I'm not even waiting for that. Deploying it in densely populated helps everyone too. It's called Big Picture. You know why Verizon's limits on unlimited are what they are? I mean besides the tired old "They are evil and greedy and they hate their customers" stuff.

    Because they offer nationwide plans so while in many areas they could offer better plans since those areas could handle the data usage. But since the plans are nationwide they have to account the worst cases of congestion. This CBRS will eventually, when deployed and enough phone use it( which will be sooner than 5G ) enable these bad areas to accommodate more data thus Verizon can offer better plans. Because these new plan are modest improvements at best( in some case not improved like Start unlimited )

    CBRS can also help with their Fixed Wireless home service

    If it’s anything like WCS, CBRS will be used it rural areas for FWI, and in suburban/urban areas they’ll use it as LTE capacity. Based on Tutela reports, it looks like about 15% of their LTE network usage is based on WCS.

    I don't know if they can use it for FWI in rural areas given the current power limitation

    WISPs currently are so what's the difference?

    You have a link?

    Currently rural WISP is 900MHz, different propagation IMO.
    IMO money will not be there to build a parallel infrastructure, not until all the low hanging fruits will be picked (urban/residential).

    A quick Google search yields nothing for FWI in the 900 MHz band.
