International expansion An early, wooden, Ericsson telephone, made by the Ericsson Telephone Co. In 1878, he agreed to supply telephones and switchboards to Sweden's first telecommunications operating company, Stockholms Allmänna Telefonaktiebolag.

His telephones were not technically innovative. In 1878, Ericsson began making and selling his telephone equipment. In 1876, at the age of 30, he started a telegraph repair shop with help from his friend Carl Johan Andersson in central Stockholm and repaired foreign-made telephones.

He worked for a firm that made telegraph equipment for the Swedish government agency Telegrafverket. Lars Magnus Ericsson began his association with telephones in his youth as an instrument maker. Įricsson is the inventor of Bluetooth technology. The Wallenbergs and the Handelsbanken sphere acquired their voting-strong A-shares, and thus the control of Ericsson, after the fall of the Kreuger empire in the early 1930s. The company was founded in 1876 by Lars Magnus Ericsson and is jointly controlled by the Wallenberg family through its holding company Investor AB, and the universal bank Handelsbanken through its investment company Industrivärden. Įricsson has been a major contributor to the development of the telecommunications industry and is one of the leaders in 5G. Ericsson has over 57,000 granted patents. The company employs around 100,000 people and operates in more than 180 countries. The company sells infrastructure, software, and services in information and communications technology for telecommunications service providers and enterprises, including, among others, 3G, 4G, and 5G equipment, and Internet Protocol (IP) and optical transport systems.
