Alcatel-Lucent & LG Electronics Complete Successful Handoff of Data Call

January 14, 2010


By Calvin Azuri - TMCnet Contributor

Alcatel-Lucent (News - Alert) and LG Electronics have completed a successful handoff of an end-to-end data call between Long Term Evolution, or “LTE (News - Alert),” and CDMA mobile networks. The live, over-the-air handover consisted of an uninterrupted streaming video session conducted over Alcatel-Lucent's end-to-end commercial LTE and CDMA/EV-DO infrastructure using an LG Electronics (News - Alert) CDMA and LTE dual mode device.
 
The handoff is compliant with the standards established by the Third Generation Partnership Project, or “3GPP.” According to Ken Wirth, president of 4G and LTE Networks at Alcatel-Lucent, since existing networks were designed primarily with voice in mind, the current explosion in data traffic is creating a challenge for service providers. The successful handoff demonstrates Alcatel-Lucent's readiness to deliver LTE to CDMA operators. LTE provides operators with the opportunity to deploy a system designed specifically to support data.
 
 The successful tests are part of Alcatel-Lucent's effort to ensure that the LTE networks of service providers such as Verizon (News - Alert) Wireless interact smoothly and seamlessly with existing 2G and 3G CDMA networks so that the user will experience uninterrupted service.
 
What’s more, active handover is highly important for a wireless network since it allows online activities to be maintained as a mobile data user moves between LTE and CDMA coverage zones. Alcatel-Lucent is one of the important vendors of CDMA and LTE infrastructure for Verizon Wireless.
 
Alcatel-Lucent employed its end-to-end LTE solution for the tests. The solution consisted of base stations, Evolved Packet Core, IP Multimedia Subsystem (News - Alert), IP backhaul solutions and associated management systems. The tests also demonstrated a feature on CDMA and EV-DO networks called Evolved High Rate Packet Data, which serves as an interface to manage the handover of data services between the two network types. 
 
LG's M13 CDMA/LTE device incorporated for the testing is the world's first modem chipset for 4G LTE devices. It was created with commercial grade components and released in December 2008. The technology behind LG's M13 CDMA/LTE terminal is important in enabling LTE networks to operate transparently with existing CDMA networks.
 
According to In-kyung Kim, vice president of 4G development at LG Electronics Mobile Communications Company R&D Center, LG's M13 terminal will be an important device in enabling CDMA network operators to deploy a LTE network incrementally over a national CDMA network.
 
To find out more about Mary Baker and Alcatel Lucent, visit the company at the 4GWE Conference. To be held Jan. 20 to 22 in Miami and collocated with ITEXPO East 2010, the 4GWE Conference will focus on the realities of deploying 4G technologies and delivering broadband wireless applications to a growing community of wireless broadband consumers. Baker is speaking during “Lessons in Application Development.” Don’t wait. Register now.
