3.7-4.2GHz band NPRM

Recommended Posts

We all know and love the CBRS band from 3550-3700MHz. There are certain incumbents in that band (cough DoD, cough) but a sharing mechanism has been established. Part of the sharing mechanism involves reduced power to avoid interference with the incumbents. What about the band above it, 3.7-4.2GHz? Well it turns out that Intelsat owns all of it as of right now. However the wireless operators have been eyeing it for a while. Verizon wants to buy a chunk of it from Intelsat, let's say 100Mhz and let Intelsat use the rest for whatever they're using it right now. T-Mobile wants the FCC to have a two phase auction ala 600Mhz auction in which Intelsat gets compensated by the proceeds of the auction. AT&T does not seem to be interested because they're busy with the Firstnet deployment and who knows what Sprint is thinking? Well what about Dish, where do they come in? Well it was long thought that Verizon was the only customer for their spectrum. What happens if Verizon gets a chunk of the 3.7-42GHz band? Between LAA, CBRS and this new band, it seems that Dish's spectrum has no buyers anymore. Tim Farrar explains it very well here:

Hmm sprint can definitely use it....but low band should be the priority.....plus no current handsets support it..;

Er, that's not true.  It's allocated to the C-band satellite service.  The licenses are, as I understand it, nationwide, but vary based on which slot in the sky the satellite is in.  So Intelsat has some slots, SES has some, and there are other companies as well that I'm not familiar with.

    • Unable to confirm if it's really off but I noticed this morning that I'm no longer connecting to Band 41 on my home site. Switching my phone to LTE-only pretty much always put me on Band 41 since it was the least used band on T-Mobile's network. Now I'm only able to connect to Band 2/66. Not complaining because it means speeds are faster on LTE and maybe 150MHz n41 is around the corner.

    • Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.
    • Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.
