Many refer to the Cellular 850 MHz band somewhat archaically as "800 MHz," but that is really a misnomer because it is too easily confused with the SMR 800 MHz band, as is the case here.Also, VZW is but one of many CDMA1X 850 carriers -- though, VZW has bought up a lot of them. But Sprint does not roam exclusively on VZW. Sprint has many other CDMA1X 850 roaming partners in various parts of the country. AJ

I see. Thank you so much for all of the clarifications that you have provided me in various places so far.

I noticed that Antenna 1 is far weaker in every category that Antenna 0 other than LTE. How does the phone decide which antenna to use when? And these are transmitting measurements correct? Can you extrapolate anything about reception capabilities of a device from this information?

Sprint is using the 800 SMR band, as you figured. But Sprint devices also support 850 Cellular band for roaming purposes.Robert

So that means that Verizon is already using the Cellular band for CDMA1x and we roam over to their frequencies? I thought that they used 800 since any Verizon phones listed at Phonearena show the devices supporting 800 and 1900Mhz.

Also I noticed that Antenna 1 is far weaker in every category that Antenna 0 other than LTE. How does the phone decide which antenna to use when? And these are transmitting measurements correct? Can you extrapolate anything about reception capabilities of a device from this information?

I'm a little confused so hopefully someone can clear this up. I notice that there are measurements for both the 800 and 850Mhz spectrum. It's my understanding that Sprint only uses the 800. is the 850 just the upper end of the 800? I figured this could be because the lower frequencies could be used for tx and maybe the higher could be for rx? Or do we just not have to bother with the 850Mhz measurements at all?
