Swedish vendor Ericsson has signed a deal with Japanese operator eAccess to launch Long Term Evolution (LTE) 4G technology alongside its existing 3G W-CDMA network. eAccess will use Ericsson’s Mixed Mode solution, allowing it to utilise the same spectrum for both its 3G and 4G networks. The commercial launch of the new LTE system is scheduled for next month, making it the first commercial Mixed Mode network in the world. Under the terms of the agreement, Ericsson will also provide eAccess with full turnkey network rollout, network optimisation and consulting, and upgrade the packet core network to an Evolved Packet Core architecture. eAccess is the smallest of Japan’s four cellular network operators, having launched its 3G network under the name eMobile in July 2007; it had 3.77 million subscribers at the end of 2011.
