Tim Yu Sprint 4G Rollout Updates September 5, 2017 - 6:45 PM PDT
It is that time of the year for flagship phablets and LG has returned to us with their brand new V30 smartphone. Unlike the LG G6, LG was not conservative with the specifications on this one.
Many other tech sites and forums have already broken down the V30 but here at S4GRU we are more interested in network technologies and the V30 is definitely no slouch in this regard.
Supported Technologies GSM 850 / 1900 WCDMA Band: 2 / 4 / 5 LTE Band: 2 / 4 / 5 / 12 / 13 / 17 / 25 / 26 / 41
4x4 MIMO on Band 25 and Band 41 up to 10 streams
256 / 64 QAM DL-UL HPUE
2xCA B25 2xCA B41
3xCA B41 4xCA B41
That is right.
The LG V30 is the first device confirmed to support 4 carrier aggregation on Band 41.
No other device out there, including the ever more popular Galaxy S8 or Note 8, are confirmed to at least technologically support 4 carrier aggregation for Band 41 (though maybe a re-certification & software update can fix that). In addition, the LG V30 is also a "Gigabit Class" device that supports 4x4 MIMO over Band 41 for up to 10 total MIMO streams which the Galaxy S8 and Note 8 does not support (the GS8 and Note 8 are not "Gigabit Class" devices on Sprint).
Furthermore, note the inclusion of LTE Band 13. One may think this mean LTE roaming on Verizon may be in the cards, but recently Sprint consummated a partnership with Open Mobile based in Puerto Rico who holds Band 13 750 MHz spectrum. As the Puerto Rico market lacks SMR 800 spectrum needed for CDMA 1x 800 and LTE 800 Band 26, it seems likely that it may be a boutique Sprint market that will utilize 10x10 Band 13 750 MHz for low band coverage. An interesting development.
So network wise, the V30 sure seems like one heck of a device that supports just about every technology Sprint is poised to utilize right now in select markets and most of the network in the near future. A potentially splendid device for the Sprint network enthusiast.

Ah... to get back to test-the-window mode, first we select Shutdown from the menu. That shuts the unit down and gets it back to the original state (that it arrived in the box). Then hold down the hidden button on the front for 5 seconds and wait for the unit to power back up. Then I can access test-the-window mode again.
Funny thing is that when I take the Magic Box outside and point it directly at the cell tower, the maximum that I get is 12 (out of 100). But when I put it in a particular window, I can get 16. So I'm using that. It is still showing Band 25, but SpeedTest is reporting a better number now than I had before in a different window.
I can do the menu option and 30-second power cycle to restart, but how do I get back to the initial test-the-window mode?
Also, lilotimz's screenshots show Relay on Band 41. But my Relay screen shows Band 25. My understanding was the the Magic Box only worked on Band 41 based on the Sprint FAQ:
Will my phone work with Magic Box?
Magic Box operates on LTE 2.5GHz frequency (Band 41), so only devices with this capability will work with it. Most newer smartphones will work but you'll need to check your device's specifications for LTE 2.5 GHz to be sure.
So how do I get back to test-the-window mode? And how do I get my Magic Box to Band 41 ? I've tried different windows, rotating it 90 degrees, and angling it. It seems to always prefer Band 25. I do have Band 41 here, but Band 25 seems stronger...
I received my Sprint Magic Box and hooked it up. I was never able to get the "button" that the two arrows point to to work, so I plugged it in.
It took about 20 minutes to initialize and lock-in. There are 3 screens: GPS, LTE, Relay.
On the Relay screen, it says Band 25. I assume that means that it is communicating with the Sprint tower on Band 25. But I thought the whole point was to use Band 41.
I tried a couple of different windows, and even flipped the unit sideways to see if it made any difference. The signal to my cell phone went from -114 to -64, so the Magic Box certainly helps with the indoor signal. That's to be expected; according to the front panel, the Magic Box is transmitting a 25 dBm signal. However, my Speedtest speed is still 4 Mbps.
Other than the 3 screens (GPS, LTE, Relay), and the 4 menu options (Change Time Format, More Info, Other Actions, Re-Run Setup), I can't find any other settings. One of the screens says that the Magic Box Technical Support phone number is 844-463-3194, but I haven't tried calling yet. I don't want them to say, "it doesn't work for you, mail it back".
Is there any way to lock the Magic Box to Band 41 ? Sprint's Magic Box checker said that I'm in an eligible zone, the coverage map shows I'm in a Band 41 zone, and prior to the Magic box my phone communicated with the Sprint tower on Band 41. But for the past 3 days , the Relay screen says that the Magic Box is on Band 25. With correspondingly with poor Mbps.
