Just caught another instance of 3rd 2500 carrier in Shentel territory. Note the standard 310120. I also note the 414 PCI that is one of the 3 PCI's for the local site used for carrier one and two. Saw this at a stop light and got the screen shot but had to start moving while going for the "service screen". I think I saw 10 mhz, not 20. I did not see any aggregation but I only got a quick glimpse of the screen before it rolled to carrier one and two being aggregated as usual. The 3rd carrier was gone. I do still have a galaxy S-7. I am not positive that it is capable of using 3Xca, but the service screen looks like it could show it. I did not get a speed test on carrier 3 either. I went back through the area again, and even hung around on a side street, but could not acquire carrier 3 at any time. I was surprised to see this as this local site is not congested. Anytime I check the speed it runs over 30 down and sometimes 60 down. I am not sure if it might be a magic box or not. I was told that Shentel is not supporting Magic boxes. The area has very good service even inside the big box Wal-mart and Lowes. I would really be surprised to find a magic box or anything else like that in this neighborhood. Location: Rouzerville, Pa.
It is essentially more time parked on 2.5 as a Sprint user then 2.3 as an ATT user, or 2.2 as a Verizon or T-mo user. I see bands 30, 66 just about everywhere these days. Those seem to be pretty primary as far as bandwidth goes, minimum 10 on band 30 up to 20 or 30 in band 66. This would indicate that somehow Sprint is not allowing service levels on band 41 to fail to band 41>25 nearly as often as other carriers are with similar frequencies i.e 30>2 or 66>2. That seems strange to me.
Because the other carriers don't use those as their primary bands nor have them deployed on every single site in the same way Sprint does for Band 41. Not to mention Band 30 and Band 66 still have farther reach than Band 41. Also Band 46 is deployed in very few places as a hotspot type of solution.
When you're on Band 41, you're on Band 41 alone. When you are on Band 30 or Band 66, you tend to be carrier aggregated with another band that has better propagation characteristics.
