A study by the MultiMedia Research Institute reports that Siemens and NEC are in pole position in the 3G infrastructure market having supplied over 30% of all Node Bs currently in use in commercial networks. The partnership between Siemens and NEC began over five years ago. In November 1999, both companies founded a joint venture to jointly develop and produce infrastructure technology for 3G. The companies started supplying their first 3G Node Bs outside Japan in December 2001 and supplied the first commercial service of Hutchison 3G group in the UK and Italy. Both companies have also contributed to Node B standardization activity in the “Common Public Radio Interface (CPRI)”, and introduced the world’s first CPRI-compliant Node B series in November 2004.
