Huawei, Vodafone Test Out Hybrid System That Combines LTE and GSM

alphadogg (971356) writes "In the hunt for more spectrum to speed up mobile networks, Vodafone and Huawei Technologies have successfully tested a technology that lets LTE and GSM share the same frequencies. The speed of future mobile networks will depend on the amount of spectrum mobile operators can get their hands on. The more they get, the wider the roads they can build. One thing they can do to get more space is to reuse frequencies that are currently used for older technologies such as GSM and 3G. But that isn't as easy as sounds, as operators still have a lot of voice and messaging traffic in those older networks. However, using a technology called GL DSS (GSM-LTE Dynamic Spectrum Sharing) Vodafone and Huawei have shown a way to allow GSM and LTE to coexist."

    does this make my eee pc faster?

    When they come up with a version of wifi that works over the dozens of miles that currently exist between me and my nearest tower, sure. But I suspect it would either look like a giant power plant attached to an enormous antenna, or just be a reinvention of the current cellular standards.

    No kidding!!! What do you say at this point?

    In case anybody reading this is five:

    Eee PC is a brand of low-end compact laptop computer formerly manufactured by ASUS.

    USB (Universal Serial Bus) is the little rectangular port in the side of your laptop, marked with a drawing of a stick figure carrying a bowling ball. (See #36 in this Photoplasty.) It's where you plug in a mouse, a phone, a memory card, or an adapter the size of a memory card that connects your computer to the cellular network.

    UMTS is the language that 3G (third-generation) cellular devices, such as phones and tablets, speak to connect to the Internet, except on Verizon or Sprint.

    A CPU (central processing unit) is the part of a computer that processes. Processing means doing the math and making choices, such as laying out where the words and pictures go on a web page. A task is CPU-bound if the CPU can't process it fast enough to keep up with all the information coming in.

    GL DSS, defined in the summary, lets 3G and 4G (fourth-generation) cellular devices share one frequency. I'm not sure how this works, but it may be done using TDMA, a fancy term for "taking turns".

      I meant that UMTS is used for packet-switched (PS) Internet data, not that it's used for only packet-switched Internet data. Besides, I'm under the impression that a lot of devices will prefer GSM over UMTS for circuit-switched (CS) voice calls to save battery; hence the lack of 3G on the original iPhone and the "3G" switch in the Settings of iPhone 3G. Finally, to maintain the post's conceit of atonement for initialism overload, I had to oversimplify a little because of the constraint of not introducing any new initialisms in the post without defining them.
