Picked up B26 in Woodside, was in the elevator with my wife and saw her phone (iPhone 5S) on LTE, and mine on 3G, and my One M8 on B26. Was awesome to see!

Your wife may let you see her phone now, but do not count on it after the honeymoon period is over...

 

:P

My god.. Triband really makes a difference in the financial district! Getting 15-20mbps on band 41 with my nexus 5 vs.. 0.05mbps with my note 2.... Will band 25 ever be usable??

Where in FiDi because as of this past Saturday there still wasn't any band 41 around wall st around 4/5 2/3 lines and over.

Noticed something weird about Sprint In this particular situation. Im in Roosevelt Field Mall normally I get straight 3G no LTE EXCEPT for when I'm in the food court. I don't understand or know where the signal is coming from because as soon as I exit the mall, I go right back to 3G with not a trace of LTE in the distance [emoji23]. Anyone wanna try to explain where this random 2 bar LTE signal is coming from.

Perhaps a repeater or something similar in the mall? Is there a Sprint store in the building?

I'm using it right now in Woodside to watch Netflix on my iPad Mini.

just want to share. I got a new phone, LG G3. it seems to be prioritizing band 41. it bounces between 41 and 25 and sometimes 26 when i am deep inside the building, but primarily on band 41. Overall, I am very impressed with the service and also the phone! it is a amazing phone. it has problem with signalcheck pro app. when connected to LTE, 1xRRT or 1x800 signal doesnt work. I rely on the sprint engineer screen ##debug#. whoever going to upgrade anytime soon, definitely check this phone out guys.

Nice buy! glad to see its running well, and yes, B41 is always set to the highest priority for obvious reasons. Our market has had huge improvements in terms of B41 optimization (B26 still needs work) I'm assuming you have not used a triband device with SCP before. Triband devices are single path, and only display either LTE or 1xrtt/800.

No issues with SCP. You are not connected to 1x when you are connected to LTE. I have a G3 as well and SCP works perfectly with it. That's just the nature of tri-band devices.

when these triband phones are on LTE, how do you get calls and texts? Also when I get calls, LTE disappears, unlike galaxy note 2. on note 2, you still had LTE when i was on the phone call.

It disappears for the same reason you're not connected to 1x while on LTE, there's ONE radio path. Triband phones use ecsfb, a software that pings the phone and tells it hey there's a phone call so drop LTE and grab me some 1x for a minute or two.

Sprint Triband LTE phones dropped SVLTE for eCSFB/CSFB

Up until these new Triband devices, previous Sprint LTE devices supported simultaneous voice and LTE (SVLTE). It could do so with two separate transmission paths from the antennas to the chipset. Voice/texting could run via 1xRTT on one transmission path. LTE could run a separate path, allowing data and voice to be used simultaneously.

In contrast, Sprint Triband LTE devices do not support two separate transmission paths. They have one path, shared by voice/SMS and data.

How it works

In previous Sprint LTE phones, when a device was in Sprint LTE coverage it would park in both the LTE and CDMA Sprint networks at the same time. When a voice call came in, it would just go straight through to the device. And signal to the LTE network would be maintained the whole time while the call was active.

In contrast, a Sprint Triband LTE device can only stay on one technology at a time. CDMA or LTE, not both. So when a Sprint LTE Triband device is in Sprint LTE coverage it parks only in LTE. And doing so means it cannot transmit calls without Circuit Switched Fallback (CSFB) on the network side. CSFB and eCSFB (Enhanced Circuit Switched Fallback) are network controls that will allow a single mode/single path network to operate in two modes, both CDMA and LTE.

Here is how it works in the simplest way I can describe. When your Triband LTE device has an LTE signal, it cannot receive or make calls on its own. It is just using LTE data happily. However, what if someone calls you? How does it get through the CDMA network to your device? Via CSFB.

When the Sprint network tries to forward a call to your device but cannot see it via CDMA, it then checks for an LTE connection to your device. If it sees one, it tells your device to disconnect from LTE for a moment and reconnect to CDMA. Your device then jumps over to take the call on Sprint CDMA and the LTE session is interrupted. This happens very fast and seamlessly. Except for the loss of data availability. If you receive a text, the Sprint network is able to route it to your device via LTE.

Circuit Switched Fallback is a great solution to the issue of Sprint Triband LTE smartphones.

thank you. i thought there was something wrong with my phone.

Just curious do iPhones also rely on eCSFB or do they use some Apple "magic"??

Iphones ping the network every few seconds for a fraction of a second.

    • In the conference call they had two question on additional spectrum. One was the 800 spectrum. They are not certain what will happen, thus have not really put it into their plans either way (sale or no sale). They do have a reserve level. Nationwide 800Mhz is seen as great for new technologies which I presume is IOT or 5g slices.  T-Mobile did not bite on use of their c-band or DOD.  mmWave rapidly approaching deadlines not mentioned at all. FWA brushes on this as it deals with underutilized spectrum on a sector by sector basis.  They are willing to take more money to allow FWA to be mobile (think RV or camping). Unsure if this represents a higher priority, for example, FWA Mobile in RVs in Walmart parking lots working where mobile phones need all the capacity. In terms of FWA capacity, their offload strategy is fiber through joint ventures where T-Mobile does the marketing, sales, and customer support while the fiber company does the network planning and installation.  50%-50% financial split not being consolidated into their books. I think discussion of other spectrum would have diluted the fiber joint venture discussion. They do have a fund which one use is to purchase new spectrum. Sale of the 800Mhz would go into this. It should be noted that they continue to buy 2.5Ghz spectrum from schools etc to replace leases. They will have a conference this fall  to update their overall strategies. Other notes from the call are 75% of the phones on the network are 5g. About 85% of their sites have n41, n25, and n71, 90% 5g.  93% of traffic is on midband.  SA is also adding to their performance advantage, which they figure is still ahead of other carriers by two years. It took two weeks to put the auction 108 spectrum to use at their existing sites. Mention was also made that their site spacing was designed for midrange thus no gaps in n41 coverage, while competitors was designed for lowband thus toggles back and forth for n77 also with its shorter range.  
    • The manual network selection sounds like it isn't always scanning NR, hence Dish not showing up. Your easiest way to force Dish is going to be forcing the phone into NR-only mode (*#*#4636#*#* menu?), since rainbow sims don't support SA on T-Mobile.
    • "The company’s unique multi-layer approach to 5G, with dedicated standalone 5G deployed nationwide across 600MHz, 1.9GHz, and 2.5GHz delivers customers a consistently strong experience, with 85% of 5G traffic on sites with all three spectrum bands deployed." Meanwhile they are very close to a construction deadline June 1 for 850Mhz of mmWave in most of Ohio covering 27500-28350Mhz expiring 6/8/2028. No reported sightings.  Buildout notice issue sent by FCC in March 5, 2024 https://wireless2.fcc.gov/UlsApp/letterPdf/LetterPdfController?licId=4019733&letterVersionId=178&autoLetterId=13060705&letterCode=CR&radioServiceCode=UU&op=LetterPdf&licSide=Y&archive=null&letterTo=L  No specific permits seen in a quick check of Columbus. They also have an additional 200Mhz covering at 24350-25450 Mhz and 24950-25050Mhz with no buildout date expiring 12/11/2029.

They're completely avoiding talking about mmWave.
