The company offers services, software and infrastructure in information and communications technology for telecommunications operators, traditional telecommunications and Internet Protocol (IP) networking equipment, mobile and fixed broadband, operations and business support services, cable television, IPTV, video systems, and an extensive services operation.
Ericsson had a 27% market share in the 2G/3G/4G mobile network infrastructure market in 2018, thus being the largest such non-Chinese company.
The company was founded in 1876 by Lars Magnus Ericsson and was taken over by the Wallenberg family in 1960; today, the family, through its holding company Investor AB, owns a controlling 22.53% voting power.
The company employs around 95,000 people and operates in around 180 countries. Ericsson holds over 49,000 granted patents as of September 2019, including many in wireless communications. Ericsson is the inventor of Bluetooth technology. Ericsson leads the implementation of 5G worldwide, partly through the use of massive MIMO technology.
Ericsson's business includes technology research, development, network systems and software development, and running operations for telecom service providers and software. Ericsson offers end-to-end services for all major mobile communication standards and has three main business units.
Business Area Networks
Business Area Networks develops network infrastructure for communication needs over mobile and fixed connections. Its products include radio base stations, radio network controllers, mobile switching centers and service application nodes. Operators use Ericsson products to migrate from 2G to 3G and, most recently, to 4G networks.
Business Area Managed Services
The unit is active in 180 countries; it supplies managed services, systems integration, consulting, network rollout, design and optimization, broadcast services, learning services and support.
Ericsson's Broadcast Services unit was evolved into a unit called Red Bee Media, which has been spun out into a joint venture. It deals with the playout of live and pre-recorded, commercial and public service television programmes, including presentation (continuity announcements), trailers, and ancillary access services such as closed-caption subtitles, audio description and in-vision sign language interpreters. Its media management services consist of Managed Media Preparation and Managed Media Internet Delivery.
