The company, which became Helsingin Puhelin in 1985,
was involved in the establishing of Oy Datatie Ab, the provider of a
national data transfer service. The state's mobile phone network
monopoly was broken with the help of Radiolinja, and after that, the
long-distance network monopoly was also ended, at the beginning of 1994.
The Ysi long-distance network founded by HPY took 50% of the
long-distance call market, and call rates decreased by more than 50%. In
1997, Helsingin Puhelin Oyj was listed on the Helsinki stock exchange,
and in the 1990s Radiolinja, FinnetCom, Tampereen Puhelin, Keski-Suomen
Puhelin and Joensuun Puhelin merged with the company.
In 2000, the company was named Elisa Communications
Oyj. A powerful sector transition was taking place in 2003: competition
became tighter and prices dropped. Operations had to be adjusted to
cater to the needs of the customers, the market and the owners. The
company was named Elisa Oyj and the Board signed the merger plans,
according to which most of the subsidiaries fully owned by Elisa merged
with the company. The German operations (Elisa Kommunikation GMBH) were
relinquished. The journey to one Elisa started.
In the 2000s, expansion through corporate acquisitions continued and
Saunalahti merged with Elisa. In addition to several other companies,
Elisa further strengthened its ICT selection to improve companies'
productivity and flexibility by acquiring Videra (videoconferencing
operator) and Appelsiini (IT outsourcing provider). In 2013 Elisa
acquired PPO Yhtiöt, Kymen Puhelin and Telekarelia. In 2016 Elisa
acquired Anvia’s telecom business, IT and hosting businesses as well as
parts of TV business.
In 2017 Elisa strenghtened its position especially
in Estonia with ES Starman and Santa Monica Networks acquisitions. In
2018 we boosted our IT expertise in the Corporate Customers business by
acquiring Fenix Solutions, and in the Consumer Customers segment, we
acquired Kepit Systems, a company specialising in streaming and video
Accelerated by digital services that utilise the capabilities of our
core business functions, Elisa’s international growth continued. International digital
services contribute a growing part of our revenue. In
2019 we boosted our automation business by purchasing Polystar OSIX,
a company that offers network monitoring and analytics software
solutions to international telecom operators. In 2020 Elisa acquired German-based industrial software provider camLine GmbH and CalcuQuote, a U.S. based supply chain software provider for the Electronics Manufacturing Services industry. In 2021 We accelerated the growth of Elisa IndustrIQ by acquiring a majority share in TenForce, a Belgian provider of production quality (EHSQ) and operational risk management software, and a minority share in sedApta Group, an industrial software provider specialising in innovative IT solutions for digital supply chains and smart manufacturing. In 2022 Elisa Polystar business expanded with Slovak based FRINX and UK based Cardinality acquisitions.
In its various phases, Elisa has been a forerunner in
almost every aspect of telecommunications technology. For example, being
the first city in the world to see this happen, the switchboards of the
entire Helsinki region were automised in 1929.
In the field of digital mobile communications, Elisa has been a
forerunner in both Finland and internationally. Radiolinja transmitted
the world’s first GSM phone call and launched the first commercial GSM
service in 1991. The first GSM data call also took place on Radiolinja’s
network in 1993.
In 2007, Elisa once again made telecommunications history, being the
first operator in the world to introduce a 3G/UMTS900 network for
commercial use. New services, such as Elisa Viihde, were introduced in
2009. In 2011, Elisa was the first company to open a 4G network for
commercial use, and opened commercial 4G/800MHz frequencies in 2014. In
2016 4G population coverage was already 98% in Finland.
We were the first operator to introduce 5G readiness to the mobile
network in Finland. Already in 2017 we started construction of the 5G
network in Tampere. The 5G readiness built into our network enabled us
to be one of the first companies in the world to launch a commercial 5G
network, already at the very beginning of the year 2019.
In 2021 Elisa was the first operator in the Nordic countries to deploy a separate commercial (standalone) 5G network. A year later, in 2022, we made a world record in 5G uplink speed.
In 2023 we introduced the first Distributed Energy Storage solution in telecom infrastructure in the world.
