5Ghz LTE Means More Data for More People

cell-phone-tower-cellphone-tower-antenna3-o

As more an more people use more and more data, two companies have tested new LTE technology that helps prevent data bottlenecks in dense population areas.

Since carrier’s began providing high speed 4G LTE service over their networks, the number of people streaming music and movies, or downloading large apps and games has skyrocketed.

Data speeds have gone way up, and with it, so have data demands, as more people switch to cell phones with faster radios on faster networks and carrier’s like T-Mobile and Sprint both push for unlimited data, or at least high data caps.

This new access to content due to faster data access is awesome for many people, but just like any transportation system, such as highways, the system that transports our data can get clogged, which sort of negates the whole point of high speed data access.

That’s where Huawei and NTT DoCoMo come in. The two companies have just recently performed a successful test of an LTE broadcast using the unlicensed 5Ghz spectrum normally used for WiFi.

Most carriers broadcast over spectrum licensed by national regulating authorities (such as the FCC in the United States). Licensed spectrum is well regulated and ensures that consumers can purchase service from one company without another company blocking or clogging the system.

The 5Ghz frequency is an unlicensed frequency, because it is used by consumers and businesses for WiFi, which would be a little excessive to regulate in the same way as the frequencies used by carriers.

5Ghz typically has lower range (only a few hundred meters) and doesn’t penetrate solid objects very well, but it does not require a large open space to broadcast, making it very well suited for mesh style networks in capacity laden cities.

Some people may find the concept of 5Ghz LTE deployment a bit redundant, considering most WiFi broadcasts use the same frequency, the two broadcasts would usually be suited for the same areas, and many people are already accustomed to to using WiFi when available since it can be more reliably and some people with data caps are looking for ways to avoid using up their cap.

This homogenization of radio frequencies is only a necessary component of wireless technology as we move forward, though. Carrier aggregation (use of multiple frequency bands in a single broadcast) is an essential component of next generation LTE Advanced, and many cellular providers are already moving towards WiFi calling and offering more “smart” network features.

The benefits of such service is undeniable. Besides the benefits of carrier aggregation, 5Ghz WiFi alone offers 1.6x the capacity of current methods, but the more networks can do, the more concerns are raised over issues like net neutrality, where wireless providers’ smart networks will prioritize traffic to offer the best quality of service.

The technology isn’t available immediately (it seems that’s always the case), but Huawei and NTT DoCoMo will continue testing through 2015, and we may actually start seeing 5Ghz deployment in 2016.

AT&T to Launch LTE Calling on May 23rd

185655677

Call quality is long overdue for an improvement.  Several carriers have proposed solutions, but AT&T may be the first solution available for use.

It’s been a long time coming, but improved voice quality is finally coming to some US carriers.  Despite the rapidly improving data speeds being offered, voice calling has been nearly unchanged since the advent of the cell phone, or the advent of the landline, for that matter.

Starting May 23rd, AT&T is enabling LTE calling for parts of various states in the midwest United States.  Specific regions within Illinois, Indiana, Minnesota, and Wisconsin will be the first to be enabled for the new LTE voice service, but the coverage will obviously expand from there.  AT&T has not unveiled an official release plan yet, but these build outs normally extend from the initial launch areas prior to adding new regions.

The only phone that will initially support the LTE voice is the Samsung Galaxy S4 Mini.  The choice of such a mediocre device suggests the initial release is also a beta test of sorts.  The Galaxy S4 Mini did not post amazing sales numbers, so the carrier can ensure that only a small number of people initially have access in order to mitigate any hiccups in the rollout.  Newer and more popular phones will be able to be updated down the road to support LTE voice as the service proves itself.

HD voice calling may sound like overkill to some, because voice quality has always been the same, but so much range and clarity are lost during transmission that even a little background noise or interference can make it extremely difficult to understand the person on the other end of the phone.

AT&T will be the first to market with improved voice calling, since Sprint’s HD Voice solution isn’t slated to be in place until July this year.  Hopefully improved voice calling catches on quickly across all carriers, but with all the legacy cell phones still in use today, networks can’t change voice service too quickly without impacting customers using older phones.

If all goes well, thousands–or hopefully millions–of subscribers will have access to HD voice or VoLTE services by the end of the year.
