Nortel and LG Electronics demonstrate 4G mobile hand-over
Nortel and LG Electronics have demonstrated what they claim is the world’s first hand-over of a mobile connection between cells using the fourth-generation (4G) LTE standard.
Engineers at Nortel's Research and Development Centre of Excellence in Ottawa showed streaming high-definition video on a prototype LTE mobile device from LG Electronics, while driving at speeds of 100km/h and moving between coverage sites.
The LTE demonstration was conducted over a network of multiple cell sites and sectors served by Nortel's eNodeB LTE base station and ATCA-based access gateway, working to the 3GPP release 8 standard.
Nortel claims the demonstration shows that the LTE standard will be able to offer reliable mobile coverage, as well as the greater bandwidth, higher capacity and lower latency that will make the introduction of 4G worthwhile.
Richard Lowe, president of carrier networks, Nortel, said: “Today's telecommunications market is experiencing a massive trend towards hyperconnectivity as more people and devices become connected. With the increasing popularity of bandwidth-intensive applications over mobile devices like laptops and smartphones, wireless operators need to prepare to offer a complete personal broadband experience.
“Operators can leverage the capabilities of LTE to allow subscribers to take their personalised versions of the Web - their videos, their social networks, their music, their business tools - with them wherever they are.”
Jinsung Choi, head of LG Electronics' Mobile Communications Tech Research Lab, said: “Nortel, the LG-Nortel joint venture, and LG Electronics are accelerating the commercialisation of LTE and showing consistent progress towards end-to-end interoperability to ensure alignment between infrastructure and devices.”
Nortel says the hand-over demonstration brings its LTE offering closer to commercialisation, which is expected by the end of 2009.
