First signs that a number of 4G LTE chipsets will appear before the end of the year have surfaced with silicon announcements from two of the leading LTE protocol stack developers.
4M Wireless has said that it has licensed its LTE stack to an unnamed fabless semiconductor company developing a 4G multi-mode baseband chip.
Germany-based developer MimoOn has said that its LTE Physical Layer and Protocol Stack Layers are available through a relationship with IP core supplier Radiocomp.
A spokesman for 4M Wireless told EW that its stack will be implemented in first LTE chips by the end of 2009.
These are clear indications that LTE chipsets for basestations and handsets will be available before the end of the year.
The LTE protocol stack is now almost finalised and only minor changes ar expected before the4 end of the year. “These will be minor changes which will be supported with software updates,” said a spokesman for 4M Wireless.
4M Wireless licensed its stack at the beginning of the year to the company developing a 4G multimode baseband chipset.
The stack, called PS100 is compliant to the latest version of the Release 8 LTE specification.
“The LTE protocol stack is compatible with legacy 2G/3G protocol stacks as well as Wimax stacks,” said the spokesman.
The MimoOn stack, which is targeted at basestation and test systems, supports the Common Packet Radio Interface (CPRI) and the Open Basestation Architecture Interface (OBSAI).
MimoOn demonstrated end-to-end LTE and high definition video streaming between its eNodeB stack and UE implementations at Mobile World Congress last month.
