Sprint to join Rural Operators Roaming Hub (CCA and RRPP thread)

So, who has what spectrum in LTE?

This AllNet Labs/Fierce Wireless discussion needs to be branched off into its own thread. Bear with staff for the next few minutes as we move posts into the new thread. Thanks... http://s4gru.com/index.php?/topic/6129-allnet-labsfierce-wireless-how-much-lte-spectrum-do-verizon-att-sprint-and-t-mobile-have-and-where/ AJ

Maybe not. Go read the comments following the Fierce Wireless article. Yeah, we have several obvious engineers and physicists stating that Sprint's BRS/EBS spectrum is "garbage," "can't penetrate its way out of a paper bag," and "will require a gazillion towers." How fortunate we are to receive their expertise. AJ

Yes, AllNet Labs seems to be painting the 2014 LTE deployments with a broad brush. That is nice for overview purposes, but it is not entirely accurate. The map does not appear to take into account, for example, the AT&T band 2 LTE 1900 deployments in a few areas or the Sprint band 25 LTE 1900 second carrier in Chicago and coming soon to other markets. This is why, when I create maps, I do not use automated data gathering methods. I collect the data by hand and vet it against my own knowledge. Of course, that takes hours on end, so it is also a reason why I do not make many maps any longer. AJ

Yeah, I appear to be correct. The BRS/EBS spectrum holdings tend to swamp the other spectrum holdings, pushing the total to the maximum depicted on the AllNet Labs map. So, for a case study, let us use an isolated rural county where Sprint has no native footprint and may not hold any BRS/EBS spectrum. Union County, NM. AllNet Labs shows that Sprint LTE downlink spectrum depth is in the 10-15 MHz range. Well, in Union County, Sprint's spectrum holdings include at least the Dallas MTA PCS B block 30 MHz license, the Amarillo BEA PCS G block 10 MHz license, and the Amarillo BEA SMR X block 14 MHz rebanded license. Thus, from an LTE downlink standpoint, that is 15 MHz + 5 MHz + 5 MHz = 25 MHz. AllNet Labs does not reflect that. Instead, it seems to count only the PCS G block and SMR X block spectrum. AJ

Pratt has a population of about 6000. Likely, few are Sprint subs. Most are VZW (former Alltel) and AT&T (former RCC Unicel) subs. The Sprint coverage corridor along US 50 serves mostly for license protection. Over a decade ago, I even predicted that footprint years before it actually was constructed. http://people.ku.edu/~cinema/wireless/crystalball.html AJ

Plain and simple, the handset is not connected when PLMN, RSRP, and RSRQ are all null values. AJ

At most sites, T-Mobile is using one legacy antenna and two modernized antennas. The two antennas do mitigate the AWS path loss disadvantage to a degree. AJ

The differences are so minimal that they could be due to experimental margin of error. Of course, that does not stop click bait sites from writing stories. AJ
