HOLLYWOOD BEACH, Fla.--Sprint (NYSE:S) CTO Stephen Bye said there is no "silver bullet" in terms of what the carrier and its peers are doing to architect their networks to handle increased mobile data.

 

"We're going to have to push the envelope in every direction," he said during a keynote appearance here during the PCIA wireless infrastructure conference. He said that as Sprint continues to deploy its LTE network, it will turn to a variety of techniques to help it manage increasing data traffic. The comments are notable considering Sprint continues to offer unlimited data services, while its main rivals have switched to metered data pricing structures.

 

Specifically, Bye said Sprint will use...

GREAT NEWS. Really makes me doubt 800 LTE is coming online by the end of this year though. If it does it would likely be Chicago, Baltimore and a few other cities but most of the country won't see this benefit until 2014

This article also makes it sound like TD-LTE on 2600 will not be live until the end of the year.  And it is live now on thousands of sites.  Sprint is making sure to under promise and over deliver.  A new strategy for them and very wise.

For those that are much more knowledgeable than me - will MIMO, bandwidth and carrier aggregation have an adverse impact on battery life?

 

I don't believe so, as I believe most of those technologies are implemented network-side.

 

This is a pretty interesting read if you're interested in learning about that kind of thing:

http://en.wikipedia.org/wiki/MIMO

 

Basically, I think this more or less means the antenna becomes "smart" in splitting up the spectrum it broadcasts on for more efficient data use.

 

As for carrier aggregation, if anything that will probably improve battery life, as the phone will likely select the radio technologies that are best suited for its location. For example, if you're in a brick building connecting automatically to LTE 800 will be more power efficient than trying to maintain a weak LTE 1900 signal.

No, what you are describing is band reselection.  Carrier aggregation would combine together both LTE 1900 and LTE 800 carriers.

I'm really hopen this Nexus 5 D820 actually pans out to be true and blue for sprint bands. Tri-band and a nexus + top shelf specs. Sign me up! if not i'll most likely wait until next year when HTC / Samshit may introduce something. I really got my hopes high atm that the d820 is the real deal, so far the d821 manual seems to be more of a international version.

so maybe Sprint doesn't want tri-band phones out till they are closer to launching...  

 

That may be true.  Falling back to Robert's statement of under promising then over delivering.

 

I know Josh has been staying on top of new developments (thank you Josh) with tri-band phones.  With our federal government in neutral, it will only further delay any new phones being tested and/or approved.

Do you mean like using both bands at the same time? I am confuzzled what you mean by combining the carriers.

Yes, that is exactly the nature of carrier aggregation.

Could it be like how T-Mobile uses one band for download and another for up?

 

 

No, T-Mobile does not.

Sorry I always thought that was the case:

 

http://en.wikipedia.org/wiki/Advanced_Wireless_Services

 

The AWS band uses microwave frequencies in two segments: from 1710 to 1755 MHz for uplink, and from 2110 to 2155 MHz for downlink

 

Right, that is the AWS-1 band, not bands.

 

A single FDD band consists of both uplink and downlink.  The frequency separation between the uplink and downlink is irrelevant.

      Uploaded data without issues on Friday. Now with the latest update I am getting "Cluster #1 skipped: invalid file format detected. File exported for inspection." Doing same with all other clusters. Did this on 4 phones in a row.  Seems to work on s24 ultra just fine. On s21 ultra it says "web data upload failed. No data to send" although 8800 records were displayed. Now gives same error as above. I have not sent the data from 3 other phones.  All should have latest update.

      SignalCheck - Android app to monitor your Wi-Fi/2G/3G/4G LTE/5G-NR signal strengths

      By mikejeep · Posted

      After several months of testing, an update to SignalCheck Pro is rolling out on Google Play. It may take up to 48 hours to become available for download. Notable changes include: Added option to display site notes for NSA 5G-NR cells. Enabling this new option (Preferences > Display Settings > Show NSA 5G-NR Site Notes) will cause the app to make an "educated guess" as to what the most appropriate site note is linked to the connected NSA 5G cell, using the PCI and the device location. If it finds an existing entry that is likely to be relevant, it will display the note along with the distance from where the strongest signal from that cell was logged. While connected to NSA 5G, these notes cannot be edited; a valid NCI is required to add/edit notes and that information is not available on NSA connections.   Added option to log cells with missing/invalid PLMN (such as NSA 5G-NR cells). Users asked for the ability to log data for NSA 5G, so a new option (Preferences > Logger Settings > Log Cells with Missing PLMN) will permit this.   Added option to display LTE info above 5G-NR info. Enabling this new option (Preferences > Display Settings > Show LTE Cells Above 5G-NR Cells) shows the same information that is currently displayed, but moves the LTE information above the 5G-NR information. Other changes: Code optimizations and enhancements. Improved Android 15 compatibility. Overhauled Purchases module. Resolved force closes impacting some GSM/LTE connections. Resolved issue with improper 5G-NR PLMN display when NR/LTE PLMNs did not match. Resolved issue with improper PLMN display with single-digit MNCs. Resolved issue with incorrect 5G-NR bands displayed on some devices due to Android bug. Resolved issue with incorrect number of neighbor cells displayed when some cells were unknown. Resolved issue with missing 5G-NR data when sector display is enabled. Resolved issue with saving 5G-NR site notes when NR/LTE PLMNs did not match. Resolved issue with settings to log missing GCI/NCI/TAC/PLMN being ignored. Resolved issues with web data export function. Updated internal libraries. Updated provider database. Updated target API to Android 15. I appreciate all of your support, and a big thank you to the members of the Beta Crew that help with testing and feedback!

      Stopped by again today and the antennas are up but it isn't live just yet. If other Sprint conversions are anything to go by it'll likely take about a month for the site to go live.

      It is an Android bug that was reportedly fixed in August 2023 but definitely has not been. I have implemented numerous workarounds in SCP to correct the NR bands the app displays. The OS ignores the possibility that many NR-ARFCNs are valid across multiple bands.. it reports the lowest NR band that is valid for the current ARFCN. In your example, channel 432530 can be n1, n65, or n66.. so the OS just (lazily) reports n1.   Awesome, thanks! I will add an n65 override also.
