Ericsson
Swedish provider of communications technology and services
Telefonaktiebolaget LM Ericsson (lit. 'Telephone Stock Company of LM Ericsson'), commonly known as Ericsson (Swedish pronunciation: [ˈêːrɪkˌsɔn] ), is a Swedish multinational networking and telecommunications company headquartered in Stockholm. Ericsson 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, and it is the inventor of Bluetooth technology.
The company sells infrastructure, software, and services in information and communications technology for telecommunications service providers and enterprises, including, among others, cellular 4G and 5G equipment, and Internet Protocol (IP) and optical transport systems. The company employs around 100,000 people and operates in more than 180 countries. The company is listed on the Nasdaq Stockholm under the ticker symbols ERIC.A and ERIC.B and on the American Nasdaq under the ticker symbol ERIC.
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. The Wallenbergs and the Handelsbanken sphere acquired its voting-strong A-shares, and thus the control of Ericsson, after the fall of the Kreuger empire in the early 1930s.
History
Foundation
Lars Magnus Ericsson began his association with telephones in his youth as an instrument maker. He worked for a firm that made telegraph equipment for the Swedish government agency Telegrafverket. 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. In 1878, Ericsson began making and selling his own telephone equipment.
Begin with the source’s own compact description: “Ericsson” is swedish provider of communications technology and services. The dossier treats that line as a proposition to test through Ericsson, Swedish and provider, not as a finished interpretation.
Why this record matters
The phrase “swedish provider of communications technology and services” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 24, 2026. The linked authority identifier is Q52618. The first chronological checks are 1876 and 1878.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
