Will older none tri-band phones like my Note 2 be able to get the battery life improvement by turning off the CDMA radio when you are connected to LTE?

It's not a software thing, it's a design of the radios. The way the radio is constructed will impact whether or not your phone will have only one radio on at a time. If this was possible, you would have been seeing it already in single band LTE phone in eCSFB markets already.

 

Hope this helps.

Sure, you can turn off your CDMA radio by switching the device to LTE only mode. You will then be unable to send or receive calls and texts :P

That's where the Ecsfb would come in, signal on LTE would turn the CDMA back on... I guess it can't do that without a reboot or something. I don't remember a lte only option on settings.

The phone has to be designed to use ecsfb.  Only the triband devices can use this.

They could, but it would require rewriting the radio firmware. Sprint could certainly do this if they wanted to, but I believe they would never choose to do so. First, it would hamper a feature of the phone they advertised (simultaneous voice and data). Second, it would be a bunch of work recertifying phones on their network which are older and they don't really care much about.

      Network Vision/LTE - New York City Market

      By Paynefanbro · Posted

      Was in Red Hook again and I swear there are more Link5G sites as there are Verizon, T-Mobile, and AT&T small cells combined in the entire neighborhood. It seemed like every other street I turned down had one installed. Hopefully carriers will start hopping on them soon. Seems like a lot of effort to go through for no one to use them.  — — — — — T-Mobile converted the Sprint site on top of NYU Langone Brooklyn in Sunset Park. I first mapped one sector of it back in November 2023 but I thought it was a small cell so I never pinned it but I ran into another sector today which caught me off guard. I'm unable to find a permit for the conversion so it's definitely a surprise. There's another T-Mobile site 1 block away that T-Mobile initially installed back in 2019 so I'm kinda surprised they're keeping both considering the Sprint conversion is on a much taller building and could potentially provide much better coverage to the entire area.  — — — — — The old permit expired for this site without any work being done but a new permit was just approved a few days ago for a T-Mobile site at this address. Description mentions 3 antennas with 2 RRUs per sector. My guess is they're doing something similar to what they did at 360 Furman St in Brooklyn where they broadcast Band 2/66 and n25/41 from one antenna. It's a bit of a downgrade considering the site it's replacing was a full build with Ericsson 6449s.

      Came across another Crown Castle Solutions multi-tenant oDAS node in Brooklyn. Located at 40.7002286, -73.9612666. Nothing on T-Mobile or AT&T so I'm assuming these are all Verizon nodes that Crown Castle is anticipating another carrier will hop on down the line.
