Ericsson Mobile Platforms AB (EMP) was the name of a company within theEricsson group that suppliedmobile platforms, i.e. the technological basis on which acellular phone product can be built. The main office was inLund,Sweden.
EMP was one of the leading suppliers of3G technology to various brands of phones. EMP did not manufacture chips themselves, but partnered with manufacturers that made them based on their reference design andIntellectual Property Rights. It was thus afabless company. These chips were then only sold to EMP customers. According to the company, EMP held the world’s largest2G,2.5G and3G IPR portfolio, with more than 20,000 granted patents worldwide.
Due to the European telecom crisis in the beginning of the 2000s,Ericsson Mobile Communications became unprofitable, and was split in two parts: one part was merged with the mobile division ofSony and formedSony Ericsson, aimed at developing mobile terminals for the consumer market.[3]
At the same time, the other part of Ericsson Mobile Communications formed Ericsson Mobile Platforms. Some of their customers wereFlextronics,HTC,LG Electronics,NEC,Sagem,Sharp,Amoi and of course Sony Ericsson. The main focus of the company was around the development of a mobile platform for the third generation of mobile telephony,UMTS.[4]
At the end of 2004Ericsson Technology Licensing was de-established, and select parts of that company was folded into Ericsson Mobile Platforms.[5]
October 3, 2008 the company showcased a handheld prototype forLTE (fourth generation mobile telephony). At this time, the company stated that they estimated to have the technology available for the market around the year 2011.[6]
The company existed for 8 years, but February 12, 2009 Ericsson announced thatEricsson Mobile Platforms would be merged with the mobile platform company ofSTMicroelectronics,ST-NXP Wireless, to create a 50/50 joint venture owned by Ericsson and STMicroelectronics calledST-Ericsson.[7] This joint venture collapsed in 2013 and remaining activities can be found inEricsson Modems andSTMicroelectronics. Ericsson Mobile Platform disappeared as a legal entity early 2009.
The company took over the internal platforms that had been developed in Ericsson Mobile Communications under names such asSandra,Jane etc., and developed a series of platforms tied to certain specific radio standards:[8][9]

Open Platform API or "OPA" is the name given to the platform used across Sony Ericsson phones in Europe.[citation needed]
In 2001, Ericsson Mobile Platforms became one of the first companies to license 3G technology platforms to mobile phone manufacturers. EMP was the first platform provider to have commercially launched handsets containing their WCDMA, EDGE and GPRS technologies.
By 2006, manufacturers such asSony Ericsson Mobile Communications,Amoi,Sagem,Sharp,LG,Samsung, andNEC, had signed licence agreements with EMP.
For 2006 Ericsson Mobile Platforms started deliveries of the U350 and U360 platforms, which was the smallestHSDPA/EDGE platforms yet. U350 is a quad-band EDGE and single-band HSDPA platform, whereas the U360 adds triple-band HSDPA capabilities.
