December 15, 2009 - ST-Ericsson, a world leader in wireless platforms and semiconductors, and Ericsson have successfully achieved mobility between LTE and HSPA networks, using a multimode LTE/HSPA device. The interoperability was realized in live networks from Ericsson in Stockholm, Sweden, using a multimode device powered by ST-Ericsson’s platform, M710.

The companies took another  step towards a wide deployment of LTE by successfully demonstrating a mobile broadband data call in an LTE network and its handover to an HSPA network. This functionality enables a smooth service between existing networks and newly deployed LTE networks.  
 
“With multimode devices consumers can enjoy new high-speed mobile broadband services and global coverage right from the launch of LTE services,” said Jörgen Lantto, Executive Vice President and Chief Technology Officer of ST-Ericsson. “Seamless roaming between LTE and today’s networks is a key device capability to enable faster introduction of LTE.”
 
“Ericsson is in the lead of the LTE development and together with the rest of the industry we will provide a true ecosystem for mobile broadband,” said Ulf Ewaldsson, Vice President and Head of Product Area Radio at Ericsson. Roaming between the two technologies, providing seamless services, are a prerequisite for our customers enabling mobile broadband around the world”.
 
The device and networks used in interoperability testing in Stockholm were in compliance with the industry standard for commercial deployment, 3GPP Release 8 March baseline.
 
Multimode support allows device manufacturers to provide consumers with flexible and versatile devices. The chipset for ST-Ericsson’s M710 platform is commercially available.
 
Ericsson and its mobile platforms division, now part of ST-Ericsson, were also first to achieve interoperability to support multimode devices between GSM and 3G networks in 2002.
 

• ST-Ericsson drives innovation in mobile broadband and new advanced services through the development and deployment of LTE:
