by Andrew J. Shepherd Sprint 4G Rollout Updates Thursday, September 5, 2013 - 5:33 PM MDT About a month ago, our FCC OET reporter, Josh McDaniel, noted that a mystery handset, the LG D820, came and went from the FCC OET (Office of Engineering and Technology). Its authorizations were uploaded, then quickly rescinded, citing confidentiality reasons. Well, today, the LG D820 authorization documents are back. And we are looking at a 3GPP/3GPP2 handset that runs nearly the full North American wireless airlink gamut: GSM 850/1900 W-CDMA 1900/2100+1700/850 (band 2, 4, 5) CDMA1X/EV-DO 850/1900/800 (band class 0, 1, 10) LTE 2100+1700/850/700/1900/800 (band 4, 5, 17, 25, 26) TD-LTE 2600 (band 41) The only notable omission is LTE 750, VZW's currently boutique band 13 -- possibly left out for political reasons, since VZW has a strained relationship with Nexus devices, or for technical reasons, as band 13 has an inverted FDD uplink/downlink duplex. But in a nutshell, this handset looks like it could be headed to AT&T, T-Mobile, and Sprint, covering all of their bases. Here is the kicker, though. One of our moderators, Tim Yu, noted a significant resemblance between the back plate in the FCC OET filing and the back plate of a mystery Nexus device in a widely circulated photo recently from the Google campus. So, you be the judge. Based on the specs and pics, does the the LG D820 look like it could be the upcoming Nexus 5??? More to come...

Of course. Our FCC OET articles just write themselves in a matter of minutes. AJ

Deem it speed and convenience. Prior to going into airplane mode or rebooting, the handset will store in memory the last SID, NID, and carrier channel on which it idled. It tries that combo first upon coming out of airplane mode or restarting. If that combo is available and is of top priority in the PRL, then the handset will not scan for any other combo -- not yet. AJ

Pretty close. But band 2/25 LTE is part of the AT&T UE regime now. AJ

It could be a political decision, retribution for VZW. Or it could be a technical reason, since band class 13 is the only one of the bunch that has an inverted FDD downlink/uplink. AJ

The FCC authorization docs show tests run for CDMA2000 band class 10 and LTE band class 41. Those are practically unique to Sprint, especially in combination. Additionally, LTE bands 4, 5, and 17 are included, covering AT&T and T-Mobile. The outlier in the tests is LTE band class 13. It is currently unique to VZW and was not included. So, if this a new Nexus 5, maybe Google is getting back at VZW for screwing over previous Nexus handsets. AJ

And just to head off the question posse, no, this mystery handset does not support SVDO nor SVLTE. AJ

Are sure he is excited over basketball? By the looks of that guy, he might be excited over an order of chili cheese fries on the way. AJ

Look who is back... https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=395625&fcc_id=ZNFD820 AJ

SMS is such a tiny chunk of data that it can be inserted into a traffic channel with no voice interruption. AJ

They can use CSFB to drop back to Rel 99 W-CDMA for voice, but I am not sure they can use HSPA enhancements while simultaneously on a voice call. AJ

Keep in mind that AT&T and T-Mobile do not offer SVLTE devices. Many people probably are unaware that SVLTE is quite rare on the 3GPP side. Meanwhile, VZW may be trying to plan around becoming the next odd man out, instead going full tilt VoLTE. But as I have said before, I hope that VZW tries it because its reputation for voice call reliability is going to go out the window. VoLTE is going to stink on ice for the next several years. AJ

Sorry, but your chances of a dual band 25/26 LTE handset with SVLTE are slim to none. Even if somehow a dual band 25/26 handset does get released, do not expect SVLTE. AJ

Well, we have gotten to the point with the HTC One and Samsung Galaxy S4 that -- if you must have SVLTE -- you could stock up on a few of those handsets and be set for the next several years. Honestly, at quad core processor, 2 GB RAM, and 1080p screen, we have reached an inflection point. Sure, specs will get pushed even higher, many to the point of ridiculousness, but much of that will be about "specsmanship" without regard to practicality. AJ

Yes, tri band LTE could be an issue, as could band class 10 CDMA2000 and band 41 TD-LTE, since no other operator uses that combination. AJ

So far, the few VZW dual band LTE Nokia, Motorola, Samsung, and BlackBerry devices released starting this year have maintained support for SVLTE but not SVDO. AJ

Oh, I did catch that part, but I was not going to touch it, not even while wearing latex gloves. AJ

Yes, HawaiiD lured me in with his lyrical, poetic paragraphs. I was practically hypnotized. I think his real name might be Ronaiah or Lennay. AJ

Infrared? That is still electromagnetic spectrum, radio waves, or however anyone wants to put it. AJ

The Dream Academy has the "Power to Believe"... AJ

You should ask Snake Plissken... AJ

If I have to fly to Hawaii, it will be to deal with one of our problematic members. AJ

Releasing FCC OET docs just after an announcement is standard procedure for Apple. Samsung wants to take Apple's place in consumer mindshare. So, I expected the same from Samsung and got reeled in. I got "catfished." I feel like Manti Teo. AJ

Actually, Josh basically works for me now. If John Legere can have a social media assistant, then Josh is my FCC OET liaison. AJ
