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.

      Sprint Super Bowl Coverage/DAS

      By RedSpark · Posted

      February is always closer than you think! https://stadiumtechreport.com/news/caesars-superdome-gets-matsing-deployment-ahead-of-super-bowl-lix/ Another Super Bowl, another MatSing cellular antenna deployment. Caesars Superdome, home of the NFL’s New Orleans Saints, has deployed a large number of cellular antennas from MatSing as part of an effort to increase wireless network capacity ahead of the upcoming Super Bowl LIX in February, 2025. It is the third such deployment of MatSing equipment at Super Bowl venues in as many years, following cellular upgrades at Allegiant Stadium for Super Bowl LVIII and at State Farm Stadium for Super Bowl LVII. According to the Saints, the MatSing antennas were part of a large wireless overhaul this offseason, done primarily “to satisfy fans’ desires for wireless consumption and bandwidth,” an important thing with Super Bowl LIX coming to the venue on Feb. 9, 2025. Each year, the NFL’s big game regularly sets records for wireless data consumption, with a steady upward progression ever since wireless networks were first put into stadiums. https://www.neworleanssaints.com/news/caesars-superdome-transformation-2024-new-orleans-saints-nfl-season-part-1-wifi-upgrades-wireless-cellular During the offseason renovation project, the foundation of the facility's new Distributed Antenna System (DAS) was the installation of 16 multi-beam, wideband spherical lense antennas that are seven feet in diameter and weigh nearly 600 pounds apiece, a model called the MatSing MS-48H180. Another 16 large antenna spheres of varying sizes and frequencies have also been installed for a total of 32 new large antennas, in addition to 200 cellular antennas inside and around the building, all of these products specifically made for high-density environments such as stadiums and arenas. The DAS system's performance is expected to enhance further as it becomes fully integrated throughout the season. The MatSing MS-48H180 devices, with a black color that matches the Caesars Superdome's roof, each were individually raised by hoist machines to the top of the facility and bolted into place. Each cellular antenna then transmits 48 different beams and signals to a specific area in the stadium, with each sphere angled differently to specifically target different coverage areas, allowing increased, consistent coverage for high-density seating areas. In addition to creating targets in seating and common areas throughout the stadium, these antennas create dedicated floor zones that result in improved coverage to the field areas for fans in 12 field-level suites and the Mercedes-Benz End Zone Club, teams and on-field media and broadcast elements. The project is also adding 2,500 new wireless access points placed in areas such as concourses, atriums, suites and food and beverage areas for better WiFi coverage.

      FCC: "We remain committed to helping with recovery efforts in states affected by Hurricane Helene. We stand ready to do all that is necessary to return connectivity to hard-hit areas and save lives." SpaceX: "SpaceX and @TMobile have been given emergency special temporary authority by the @FCC to enable @Starlink satellites with direct-to-cell capability to provide coverage for cell phones in the affected areas of Hurricane Helene. The satellites have already been enabled and started broadcasting emergency alerts to cell phones on all networks in North Carolina. In addition, we may test basic texting (SMS) capabilities for most cell phones on the T-Mobile network in North Carolina. SpaceX’s direct-to-cell constellation has not been fully deployed, so all services will be delivered on a best-effort basis." Space posted this at 2pm today on X.
