In 1985, Cellnet was launched as a subsidiary of Telecom Securicor Cellular Radio Limited, a 60:40 venture between British Telecommunications and Securicor respectively.
In 1999, BT purchased Securicors shares in Cellnet for £3.15 billion, Securicor originally invested £4 million in Cellnet in 1983, the company was later rebranded as BT Cellnet, and it became a part of BT Wireless, a group of subsidiary companies owned by BT.
2001–2005: O2 as an independent company
In October 2001, at a general meeting held in Birmingham, 4.297 billion British Telecommunications shares voted in favour of the demerger, and 0.67 million voted against. In 2001, BT Cellnet demerged from BT and was relaunched on 1 May 2002 as O2.
In February 2004, the company was subject to rumours of take-over bids from KPN, the Dutch telecommunications group though these never came to fruition. In 2005 rumours of KPN (and several other international network operators) bidding for the various branches of O2 persisted, though following the companys posting of better than expected results so soon after demerging some speculation shifted to O2 itself making bids for other businesses.
In March 2005, the company underwent a corporate reorganization, that saw mmO2 plc being de-listed from the London Stock Exchange and acquired (via a share swap) by a new company, O2 plc, which was listed on the London Stock Exchange in its place. The summer of 2005 saw the company under threat of crippling strike action by Communication Workers Union members following disputes over pay and remuneration, though unrelated to earlier job losses as part of the reorganization. This was resolved without strikes taking place after several months of negotiations between the company and the trade union.
2005–2006: Telefonica transition
On 31 October 2005, O2 agreed to be taken over by Telefonica, a Spanish telecommunications company, with a cash offer of £17.7 billion, or £2 per share. According to the merger announcement, O2 retained its name and continued to be based in the United Kingdom, keeping both the brand and the management team. The merger became unconditional on 23 January 2006. O2 is now a wholly owned subsidiary of Telefonica.
Following the completion of the acquisition of O2 by Telefonica in February 2006, Telefonica undertook a corporate organisational change that saw the merging of its fixed and mobile businesses in Spain, and the transfer of Telefonicas non-Spanish European telecommunications properties into the O2 brand. Thus, the Cesky Telecom and Eurotel operations in the Czech Republic as well as the Telefonica Deutschland business in Germany were brought into the governance of O2, which retained its U.K. registered public company status with its own board of directors and corporate governance structures and processes.
Telefonica chose to keep their existing mobile phone operations in the rest of the world under the brand Movistar. This name is used in Spain and in most of Latin America countries, operated by a separate management team.
2007–present: Industrial expansion
On 15 July 2009, O2 entered into the financial services industry with the launch of O2 Money. The launch marks O2s first stage at implementing financial services into mobile phones. Future plans include manufacturing Near Field Communication (NFC) technology in mobile phones in the United Kingdom. It was also announced that its NFC technology is ready, but pending support from large retailers and handset manufacturers before a mass rollout.
O2 began trials of NFC technology in 2007, with 500 individuals participating in the trial. The individuals used a selection of Nokia handset to make payments at selected retailers, and travel the London Underground with transactions made via Barclays. O2 is now in discussions with large retailers for the deployment of the necessary electronic point of sale units, and with handset manufacturers, to enable NFC technology on all future devices.
On 18 November 2009, O2 announced a £500 million expansion and upgrade to its network throughout 2010, with the addition of 1500 new cell sites to support the increasing popularity of mobile broadband.
O2s mobile network covers ninety-nine percent of the United Kingdom, with the companys 3G network covering eighty-four percent of the United Kingdom and is fully HSDPA-enabled, and provides speeds of up to 3.6 Mbps for HSDPA-enabled devices. It is the second largest mobile operator in the UK.
In 1993, O2 launched 2G services in the United Kingdom, and its analogue eTACS service was discontinued in 2000, as part of changes to the regulation of spectrum in the United Kingdom.
In the United Kingdom, O2 and Vodafone have exclusive rights to the 900 MHz spectrum, wholly due to them being the only two mobile operators operating when the spectrum was actioned.
In November 2009, O2 announced it would erect 1,500 new cell sites throughout the U.K. in 2010.
Since 2007, O2 has invested over £500 million on its 3G network, which covers eighty-four percent of the United Kingdom.
On 15 December 2009, O2 announced that it successfully demonstrated a 4G connection using LTE technology, supplied by Huawei, installed in six masts in Slough. The trial achieved a peak downlink rate of 150 Mbps. The trial was part of a technical demonstration, as opposed to the first stages of deployment.
Future versions of 4G are predicted to reach speeds of up to 1 Gbps.
In September 2009, O2 and Arqiva, partnered with Nokia and terrestrial and satellite broadcasters for a six month trial in Oxford that tested DVB-H technology that allows mobile phones to receive television signals directly. Sixteen channels, including BBC One, ITV1, and Channel 4, were available to 400 individuals who participated in the trial.
O2 is partnered with The Cloud and BT Openzone to offer 7,500 Wi-Fi hotspots across the United Kingdom.
On 23 April 2010, O2 launched a free application for the iPhone called FastConnect. The app allows iPhone users who are subscribed to O2 to access over twenty-two thousand Wi-Fi hotspots across the United Kingdom via The Cloud, free of charge. The app features a Wi-Fi hotspot locator, providing automatic connection to all Wi-Fi hotspots powered by The Cloud when in range. The app was launched due to iPhone users jamming the 3G networks across the United Kingdom, due to increased use of all-inclusive data tariffs.
