Nokia Siemens Networks has acquired a certain part of Motorola Solutions’ Networks assets by paying $975m in cash.

Through the acquisition, the responsibility for supporting customers of Motorola Solutions’ GSM, CDMA, WCDMA, WiMAX and LTE products and services transfers to Nokia Siemens Networks.

Nokia said that the acquisition strengthens its position in key regions, particularly North America and Japan, and with some of the world’s major service providers.

Based on revenue, the addition of Motorola Solutions’ Networks assets makes Nokia Siemens Networks the third largest largest wireless infrastructure vendor in the US and the leading non-Japanese wireless vendor in Japan, said the company.

In addition, the acquisition reinforces Nokia Siemens Networks’ position as the world’s second largest wireless infrastructure and services provider.

Nokia Siemens Networks chief executive officer Rajeev Suri said the people, customers and technology they’ve acquired complement their existing business by taking them into new markets and broadening their market share.

"Our combined knowledge and experience will provide our newly expanded customer base with the means to grow by providing greater value to their subscribers," Suri said.

As part of the deal, responsibility for supporting 50 operators across 52 countries, and approximately 6900 employees, will transfer to Nokia Siemens Networks.

In addition, Nokia Siemens Networks is acquiring a number of research and development facilities including sites in the US, China, Russia, India and the UK.
