T-Mobile - More Coverage, More Capacity: New 5G Band n25 & 3x Carrier Aggregation 

1. I hope you can help me clarify this question. To clarify, I have a fundamental question that relates to Dual Connectivity i.e. N-DC refers to the dual connection of 4G wireless access network and 5G NR. I am asking you as I have attended and subscribed to Award Solutions webinars in the past. 2. Let’s say that we are using Band-X in 4G and another similar band in 5G and are attempting to communicate with both RATs to take advantage of EN-DC. 3. The question is what will happen if there is overlap in terms of the “spectrum occupied”. 4. Let’s say that the 4G component has been assigned spectrum in Band 3 from 1830 MHz through to 1850 MHz (i.e. a chunk of 20 MHz Bandwidth). 5. Let’s say that the 5G component has been assigned spectrum in Band n3 from 1820.45 MHz through to 1830.45 MHz (i.e. a chunk of 10 MHz Bandwidth). 6. In such a scenario, there is an overlap of 450 KHz between these two components i.e. the assigned 5G-NR band component eats into the 4g spectrum component by 450 KHz. 7. Will such a deployment work in light of the designated configuration based on existing product implementations? There are bound to be issues in decoding such transmissions at the UE because of the overlap in the spectrum. The reason, I am asking this question was because an argument (however erroneous) can be made that the 5G transmissions would potentially be orthogonal to the 4G transmissions (even if they have an SCS of 15 kHz or 30 kHz) and hence the decoding at the mobile will work because orthogonality will prevent any decoding issues. I do not agree with this argument i.e. that the orthogonality provided by the OFDM structure of the waveforms would protect them against each other (i.e. from the UE perspective in the sense that the UE can successfully decode the two transmissions). I would be very grateful if you could enlighten me with your perspective with references (if applicable). 8. If the answer is in the negative, from an R&D implementation, perspective - what changes would one need to implement to make such a configuration (i.e. characterized by overlapping assigned spectrums) workable in realistic network implementations? 9. It would also be immensely helpful if you could further substantiate your arguments with references from the relevant 3GPP specifications (or other relevant specifications) or draw my attention to any specific specifications or publications which can further clarify my doubt?

The most recent T-Mobile Home Internet router's spec sheet says that it supports the n25 band. No word on carrier aggregation. From the UI it seems to pick strongest signal.

On Apples website it says the iPhone 12 will support n25, and it’s got the Qualcomm x55 modem.

Awesome video! However, I'm pretty sure the Pixel 7's Exynos 5300 modem also supports 3CA, not just the Qualcomms

iPhone 14Pro series rocks a X65, confirmed to get this feature sooner than later.

I live out in the middle of nowhere in Amish country and, until T-Mobile, was a slave to the local cable provider that serviced our area. Honestly, we felt pretty lucky to have cable service out here at all... Although I've been streaming for a decade. I've been using their 5G internet gateway for several months and I'm pretty impressed with the service. I don't need scorching fast speeds and the 200 Mbs down and 30 Mbs is faster than I was getting on cable for $30 a month. Literally the cheapest internet I've ever had.

I have Mint Mobile the sister of T Moble and have the 5G with them.. Been able to get high speed service everywhere except at my parents ATT house.. I even get full service inside Walmart, Lowes, and HomeDepot.

Currently running the beta version of 16.4 on the iPhone 14 Pro Max and it's running 5G standalone (double checked in field test mode) and as of now I'm getting Band 25. It isn't much faster than B41 w/ an aggregated dl bw @ 100. Not complaining though, our speeds range wildly from 200Mbps down to 800Mbps down.

I've been able to connect to N25 on my OnePlus 9 pro it's actually pretty good above 100mbps with like 3x or 4x aggregation not sure why they say it's limited to the S22

Always helpful and informative.

I am able to use this already. I live nearly 6 miles from the nearest tower. I’m on the iPhone 13 Pro Max. I got the 5G stand-alone update, and there’s definitely a difference. Before I got 5G stand-alone, my speeds were roughly around 200mbps on average, now I get 800mbps on average. With me being 6 miles away, that’s just nuts! They’re definitely heading in the right direction. Edit: my average signal I get is 2/4 bars (50%)

Very nice and all the 5G, but a lot of battery spends and I prefer 4.5G.

Interesting. If they could get 5G over voice and have a true 5 SA it will be interesting. Wonder have how much MHZ of N25 they have and that N25 should have pretty good range over 2 miles

Any ETA on when this should be turned on at their towers? Not sure if that is how it would work

Do any of the T-mobile hotspots have the Qualcomm n65 chipsets that you talk about?

Thanks for the info. Now we can see the value the new MiFi X Pro 5G M3000 will add. Question? Do we know anything more about the unlocked M3000A?

My phone network band in t mobile?? But why 😢

I have the Peplink BR1 Pro 5G router in my boat...is it compatible with this new T-Mobile 5G aggregation offering?

Will n25 and carrier aggravation be available on their up coming gateway ?

I have a question I have been having difficulty finding an answer to. I use an S22 Ultra on Tmobile. Considering a new Inseego mifi x hotspot. S22 has qualcomm x65 chip, and Inseego X62. Question is: Will the hotspot get better reception than my S22Ultra? Or is it the same? (Same question for the upcoming x65 carrier agnostic version please!!). Mostly unrelated to this video topic, but also considering the 3 channel banding. My primary use case is distance like the n71 band. I could use the other benefits of a hotspot. But really need to know if the reception is different from devices with the same modem, or if they are also the same antenna. (Also, I may get an S23 which is rumored to have the n70 chip). Thank you in advance I really appreciate your channel!

I wonder if they'll bring it to my tower though it's a more rural one.

sprints spectrum besides b41 will be used. Finally

Hopefully it comes to iPhone with 16.4.

iPhone 13 Pro Max doesn’t support 3 carrier aggregation right

That doesn't work where I am 5g doesn't stay on your phone I left tmobile to att and there 5g is stable and doesn't move like tmobile

Currently trying out T-Mobile in Florida and I am not impressed, att is superior in all places I have tried.

Will my phone will get it I have a 5g phone

Help help!!!!!!.... I have TRAVEL DATA.......got email today.......more that doubled the rate of 63.00 month....... no more unlimited 1000 cap......please help any idea where I can go for unlimited and at a low price.......please and thank you for you advice

On other words ,tmobile wants to sell you a new phone to make it work.shouldnt surprise anyone.cant get something for nothing.

N25 and n26 is nothing but sprints old FDD lte

My S22 and One Plus International plan is ready to be set loose!
