alphadogg 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.
