Fierce has a poll posted... and is utilizing a bracket style contest to find out who their readers think is the most powerful person in the telecom industry. Between Marcelo and the pink clad Chihuahua of a man... I give it to Marcelo. I think the final winner should be Masa, it's is a name people know and will get to know more in the coming years worldwide. But for the current poll, it's an easy decision for me!
For Ericsson markets t-mobile uses what is known as AIR antenna units which have the radio unit integrated with the antenna. This type of setup significantly reduces signal loss from the radio to the antenna since they're both practically next to each other and not sepearated by coax jumper cables like that of a remote radio unit.
Basic Ericsson AIR21 setup
(Note typically there are 2 Ericsson AIR per sector)
Ericsson AIR21 + Band 12 700 mhz Equipment
Note the addition of a new low band 700 mhz capable antenna + Ericsson RRUS11 B12 (remote radio units) in addition to new TMA (tower mounted amplifiers) connected to the AIR antenna. The new Ericsson RRUS11 B12 + Antenna addition is for tmobiles band 12 700mhz (L700) deployment.

With the introduction of the new plans Sprint has announced. I told one of my friends about the $60 unlimited plan and she was shocked yet happy about it. She currently has T-Mobile and there has been times where my Sprint service has out performed her service even in the city with puling up information and out of town...well... you already know how that went. She was talking about switching and stuff but then she sent me a typical article bashing Sprint and I got irritated by it and I had to explain to her that Sprint is not bad at all. These articles are based on past experiences from 3+ years ago. I told her I'm pulling 60+ mbps on LTE but she's worried about Sprint being slow ( because of what she read). Guys give me some advice on persuading her to give Sprint a chance.
I feel like articles that are being posted is what keeps away customers. It makes no sense that T-Mobiles 2g network is not spoken about when they are in the news for changes to plans and such. But good ol Sprint makes changes and articles that get posted rips Sprint apart for filth.
Roger Cheng @cnet appears to have had the most fun out of this, it kind of wrote the story for him I guess, so there is that. Also, just noticed the extra title Q, that is gonna drive some people nuts today. Top lel.
No it's real VoNR. It sets up the equivalent of a dedicated EUTRA session (I forget what it's called in NR) for it with the proper bearer. NSG isn't really able to decode a lot of the VoNR signaling to get codec details and such yet. There are likely a lot of issues with it still. It's probably not supposed to be public yet, and it's a fluke that you can access it by forcing SA. It probably won't launch more widely until the x60 comes out, which is the first modem that's supposed to support it. Regarding the SIM swap, I doubt it. In my experience, changing the SIM resets all locking back to none/default. But you can certainly try.
Question is whether SA would stick after a SIM swap back to Sprint. I have a Straight Talk data-only SIM that I could reactivate that sits on TMo, so I could test this.
As for VoNR support, betting that it isn't actual VoNR, but basically the NR equivalent of CallingPlus/WiFi calling, where calls run over IP without QoS. Same idea as VoIMS on the iPhone when you don't have service from one of the SIMs.
If you had a T-Mobile SIM you could get into the service menu and force SA. The Sprint SIM locks out the dialer code. It appears that the S20 actually has some support for VoNR when locked to SA on T-Mobile. The signaling (captured via Airscreen, which is basically the PC version of NSG) seems to show everything as NR without LTE fallback, since the phone advertises to the network that it doesn't support LTE when locked. And this seems to only work on the S20, not other SA capable 5G phones. But there's still a little uncertainty with it. Either way, T-mobile is making progress with it and appears to be ahead of a lot of providers. Sent from my Pixel 4 XL using Tapatalk
