Stockholm, Sweden is the place to be for cutting edge LTE technology. An active LTE network has been deployed and is being extensively used for testing — one of the first successful trials demonstrated the interoperability of LTE and HSPA networks. In the trial, a multi-mode LTE/HSPA device powered by ST-Ericssonâ€™s commercially available M710 platform was used to launch an LTE mobile broadband data call. The call was then successfully transferred from the LTE network to an HSPA network. Sounds like small beans but seamless switching between LTE and HSPA is critical for the smooth transition from our current network technology to LTE, and with this first successful hand-off, we are one small step closer to commercially available LTE.
