Qualcomm’s request to test LTE-U with T-Mobile approved by the FCC


Right around one month after Qualcomm asked for permission to test LTE-U with T-Mobile’s help, it’s gotten the A-Okay to do just that.

Qualcomm has received a Special Temporary Authorization (STA) from the FCC in order to test LTE-U and Wi-Fi technology. There are four locations in which Qualcomm will be testing LTE-U, including T-Mobile test facilities in Bellevue, Wash. The other locations include Simi Valley, Calif.; Richardson, Texas; and North Las Vegas, Nev.

There are a handful of special conditions that’ve been attached to Qualcomm’s STA. For example, Qualcomm must coordinate and comply with the Western Area Frequency Coordinator in Ventura, Calif., before testing in the 5725-5850 MHz spectrum. Additional, Qualcomm needs to get consent of local AWS licensees before using the 1695-1780 MHz, 1915-1920 MHz, 1995-2020 MHz, or 2110-2200 MHZ bands.

Qualcomm’s STA will expire on October 21.

Here’s what Qualcomm SVP of Government Affairs, Dean Brenner, had to say about today’s STA:

“Qualcomm continues to prove fair coexistence between LTE-U and Wi-Fi through our own testing, through third-parties and through our work with other stakeholders within the LTE and Wi-Fi industries. Today the FCC has once again granted Qualcomm a Special Temporary Authority to further test and develop LTE-U technologies and ultimately bring products to end-users. Qualcomm is very pleased that the FCC granted our request and will continue to work with the FCC and other stakeholders to ensure LTE-U will fairly coexist with Wi-Fi.”

Utilizing LTE-U would allow T-Mobile to boost its coverage using unlicensed spectrum, but some people are concerned that LTE-U could interfere with existing Wi-Fi. Qualcomm has been working to show that that’s not the case, though, having already conducted some tests with Verizon and now getting ready to do some testing the help of T-Mobile. Now Qualcomm has gotten the go-ahead to start it’s testing, so we’ll have to wait and see whether it gets the evidence of LTE-U/Wi-Fi coexistence that it’s looking for.

    As I demonstrated to Fraydog before, LTE-U does not interfere with Wi-Fi, as tested by Qualcomm. And as a bonus, it actually protects Wi-Fi from itself, as they discovered Wi-Fi is in fact Wi-Fi’s own enemy.


    • Allen Alberto Enriquez

      Yes I know you are always right Fabian Cortez! I’ve been around for over 10 years and notice you have great understanding! Good looking out! I love facts and you defiantly proved Fraydog! Another note I am shocked how fast FCC approved!

      • SBacklin

        Your nose brown yet or Fabian’s alternate personality? LMAO. I’m sorry but your comment is either sarcastic or just really cheesy. LOL.

        • riverhorse

          Nah, nothing untoward there.
          AAE is just stating Gospel pretty much… Fabián usually spot on.

          Now, this being the Internet, you don’t know who I am either – I could be the brownoser to the brownoser, or card carrying member of the Circle Jam Club.
          Rest assured, I’m a married man… although that doesn’t assure much in these Metrosexual times we live in. Rotflmao.

          And the thread gets weirder and weirder. LOL

        • carl

          And whats fraydog? This is like a movie trailer, now i wanna see the ending, but something tells me its gonna suck. LOL

        • Allen Alberto Enriquez

          Sarcastic it’s been on my shoulders for a while now about this thing with Fabian and finally almost a year ago has been solved

      • Fabian Cortez

        No, I’m not always right but thank you for your words.

        The point is that Fraydog (and I’m sure others) has (have) since changed his (their) mind(s) and position(s) as it relates to LTE-U/LAA. And that’s a good thing as he has since been educated on the matter. Whether I or he or someone else educates him, matters little. Just as long as we all continue to educate ourselves as we go.

        • Allen Alberto Enriquez

          Totally Fabian! I agree education with facts is best!

    • SBacklin

      I’m very anxious to see how this plays out. How much of an advantage does this have? What kind of speeds can a company see using this tech?

      • Fabian Cortez

        Pretty much up to the amount of available carriers.

        There’s a good 500+ MHz of unlicensed spectrum in the 5 GHz range.

    • Adam

      I’m going to hold off judgement unit seeing tests by a company that does not have a financial interest in LTE-U approval.

      • Fabian Cortez

        I’m going to hold off judgement unit seeing tests by a company that does not have a financial interest in LTE-U approval.

        Did you hold off on CDMA as well? Because it has been quite successful.

        • Or GSM or WiFi or Bluetooth or Ethernet or everything?

      • The companies which criticized LTE-U have no financial interest in its approval, yet proved to also be technically incompetent in their criticism.

      • carl

        I hope the technology to be deployed becomes standardized first, just because i prefer unlocked phones.

  • riverhorse

    Hhhmmmm…. North Las Vegas… Home to a diverse community: Bloods, Cryps, Nuestra Familia, Mara Salvatrucha, Black Pistons, Pagans, Sons of Silence, Vagos, Bandidos, Hells Angels, Mongols, Outlaws, Cossacks, Scimitars, Vaqueros, etc.

  • LTE-U should allow carriers to cover dark corners without much regulatory hurdle, as in shopping malls and subway stations and trains.

    However, the 500 MHz or so available has to be shared among several carriers using TDD, so the effective bandwidth an user might experience is likely to be much less than that, namely 20 MHz for a short time slice.

    • Fabian Cortez

      However, the 150 MHz or so available

      It’s actually ~500 MHz.

  • Magnetic

    I live in North Las Vegas. I wonder if I should be on the lookout for something different on my iPhone 5s as far as signal reading?

    • VN

      Nope. LTE-U will require new equipment and since it has a very short range, similar to Wi-Fi, it will reside mostly inside buidings and homes using specific routers using your home internet.

    Sprint has deployed LTE on the 2.5Ghz, what’s the difference?

    • slybacon

      I believe this spectrum is 5Ghz, and you don’t have to buy it, it’s unlicensed. Sprint paid for their 2.5Ghz. Someone else also mentioned less regulatory approval is possible…so it could just be deployed whenever and wherever (my guesses).
