The buyouts haven't been accepted by any of the Mexican Operators AFAIK. In fact now that AT&T bought out Iusacell it might be longer. There is a meeting later this month with the operators. A few have even been adding more and more customers. The Mexican government is not 'giving' any replacement spectrum. Rebanding on 26 in the south is up to Sprint/Softbank either spending the money to make it worth going out of business or offering a plan to split 800SMR in a way everyone can use it and be in business. For example put CDMA on 800SMR so that the Mexican Operators can do GSM, UMTS or CDMA since iDEN is getting harder to support. Sent from my Nexus 6 using Tapatalk

B41 now up and running in El Centro and Brawley Sent from my Nexus 6 using Tapatalk

Yuma and El Centro Drive thru - made the San Diego to Phoenix drive last week and picked up some new signals. Sprint has a 20mhz carrier up in El Centro covering brs2 e1,e2,e3. I picked up 4 difference enode ids along the interstate. In Yuma I picked up a 15mhz block on b1 b2 b3 in 3 sites and also in Somerton. Sent from my Nexus 6 using Tapatalk

Canada has some action but along the western part of the Mexican border there are still several Mexican operators that Sprint doesn't seem to be in a rush to negotiate with. The Mexican operators aren't getting replacement bandwidth from Mexico for free at this time. Sent from my Nexus 6 using Tapatalk

I think of release level as a list of minimums. One manufacturer I've dealt with had b41_b2 and b41_b4 in a 'their' release 10, which is why I initially said R10. The release level is (primarily) for the mobility management entity (MME) of the evolved packet core (EPC). For CA all of the radios need to be on the same MME. All of the software for the radios and the other core items such as the s and p gateways have to match support. A top 4 carrier will have many of these EPC service nodes. In 4g the subscriber data is in a HSS and SPR. That is essentially replicated databases. It is completely possible that one geographic area has different 3gpp release levels than another. Generally one EPC serves an area. There aren't any public lists of which areas are served by an EPC or what level it is. One would have to look at the handsets spec sheet to determine what features a handset support. Hope that helps. Sent from my Nexus 6 using Tapatalk

Correction. That is rel 11 Sent from my Nexus 6 using Tapatalk

Intra band 41 CA is rel 10. Sent from my Nexus 6 using Tapatalk

I was just in the i8 to i10 corridor the last 10 days. In Yuma I picked upto 80mhz of b41 on 312790 which is Beamspeed. Coverage from the California border to Mohawk Pass. Yuma seems to have 2 carriers per site centered around 2660 and 2630, but 2 different ones near the mountain pass at 2600 and 2640. East of wellton just 2660. I think there are 9 sites or so on that corridor. I didn't have time to run south to the border. I also saw a bunch of wimax. In Casa Grande I picked up 3x20mhz and 1x5mhz. Showed as 001-010. That's a testing code. In Tucson just 5 or 6mhz on BRS1 and 2. Not lte, probably wimax. Nothing else really to report. No b41 in El Centro either. No 5x5 band 26 either. Lots of iDEN sized carriers in all of those places as well. Sent from my Nexus 6 using Tapatalk

I'll be at CCA in Fort Lauderdale next week. I'll see what I hear. The CCA hub is run by TNS. Each participant may enter into an agreement with any other participant. The hub takes care of the signalling and settlement $ between participants. It operates in a similar fashion as a grx exchange. Sent from my Nexus 6 using Tapatalk

I've been working a rf project in socal and southern Arizona. Last week I drove I8 San Diego to El Paso with a spectrum analyzer and there isn't a 5x5 block open any where near population. So no band 26 for a while. Most of it was small channels from Mexico but in San Diego, El Centro, Yuma, Tucson and El Paso all had 800mhz on the US side. I know Motorola is doing Pima county rebranding now, but there still seems to be southern iDEN running. Sent from my Nexus 6 using Tapatalk

Please look at the FCC ULS again. You will see that Sprint has all of EFGH outside the protected P35 licences that they don't hold. So other than service for population in Dateland and north of YPG, Sprint has BRS1/2 and B, yielding a whopping 16.5 mhz contiguous plus Brs1 brs2 and b4. Call Troncatel in Mexicali. They will tell all about band 26 and Sprint Sent from my Nexus 6 using Tapatalk

Band 41 is coming up in Yuma. Just not on Sprint. I rolled thru there last week and Beamspeed looks to be turning up there and they have 7 of the 8 Ebs/brs licenses. Sprint only has the 2 small BRS licenses and the B Block. Sprint will need to make a deal with them. Band 26 doesn't look good either from Tijuina to El Paso. Word is that Sprint was trying to get the Mexican carriers moved but low balled them. There is no official Mexican rebranding.
