Airwave was established in 2000 by BT as BT Airwave. BT Airwave along with BT Quadrant secured a Public Private Partnership contract worth £2.5bn to supply of Professional Mobile Radio communications to the police and other ‘blue light’ services. BT Airwave was part of the BT Wireless division which was spun off from BT Group in 2002 to ultimately become part of O2 and became Airwave O2 Limited, commonly known as O2 Airwave. In April 2007, Airwave was acquired by two Macquarie Groupinvestment funds, Macquarie European Infrastructure Fund II and Macquarie CPPIB Communications Pty Limited, for £1.9 billion. On 3 December 2015 the company was acquired by Motorola Solutions for £817million. Some of the payment was deferred to the following year and Macquarie were supporting the transaction. On 19 February 2016 Motorola Solutions announced it completed its acquisition of Airwave,
Replacement
In April 2014, the government announced the emergency services mobile communications program to migrate emergency services to a 4G based network to be called the Emergency Services Network. One of the intentions of this program is to switch from the private Airwave network, to an existing commercial network. The switch was intended to begin in 2017 and be completed in 2019 before the existing Airwave contract was set to expire. Implementation of the network was split into three lots. In June 2015, O2 announced they would be pulling out the bidding process for providing mobile services which left only EE in negotiations. At this point Airwave was not listed as bidding for operating any part of the ESMCP. In August 2015 the delivery partner was named as Kellogg Brown & Root. Finally, in December 2015 EE was officially announced as the provider of mobile services and Motorola Solutions was named as the provider of user services. In January 2017, the Public Accounts Committee announced that the ESN might not be ready for its December 2019 deadline. In September 2018, it was announced that Airwave's existing contract would be renewed until December 2022.
During the 2011 England riots, several police officers experienced "significant difficulties" with the Airwave equipment and were forced to use their own personal mobile phones to coordinate strategy during the riots. The Police Federation review speaks of "significant local technical difficulties" and a "significant communications failure," which was quoted in the Guardian newspaper. However, the National Policing Improvement Agency responded that the network did manage to cover all 16,000 officers and that "ome officers had to wait a few seconds for their calls to get through, but fundamentally, the network proved to be most resilient."
