[4] In 2013, the company acquired Helsinki-based applications developer, Portalify and launched a range of Digital Mobile Radio (DMR) products, covering UHF and VHF frequency bands.

The following year, Sepura acquired Fylde Micro, pioneers in radio trunking, enabling DMR Tier III to be offered as part of their portfolio.

[5] Based on the financial issues, Sepura withdrew its DMR range of radios citing at the 2016 AGM "that the board now believes it will not be possible to achieve further market penetration without significant additional investment."

[7] On the 16 December 2016, the Sepura board recommended the shareholders accept a bid of 20 pence per share from Hytera as a cash purchase.

[8] Ofcom, Britain's regulator for UK communications industries, in December 2022 fined Sepura £1.5m for a breach of competition law.

In 2018 Sepura and Motorola were in competition for a contract to extend the Airwave digital radio system for police, fire and ambulance services.

As a result, Sepura radios have made appearances on well-known programmes such as Eastenders and Coronation Street, as well as crime re-enactments and real life ‘police action’ documentaries.

The 8000 series was designed to cope with the needs of the search and rescue users in the jungles of Malaysia; frozen winters experienced by Swedish Police and fire services; and downpours and floods that were occurring in many parts of the world.

The STP8000 was the start of Sepura's new genre of tough, go-anywhere TETRA radios, that not only appealed to the world's emergency services, but gained a whole new range of users, keen to take advantage of its ruggedness.

Launched in 2010, the SRG3900 was a popular addition to Sepura's range, providing 10 watts of RF power, and gateway and repeater technology to extend communication into areas otherwise beyond network coverage.

It had the greatest operational range of any TETRA terminal on the contemporary market and was deployed everywhere from ski resorts to mines and chemical parks.

In response to this and other new challenges, the STP9000 series drew on the ‘tough technology’ developed for the STP8X and went one step further, being designed to be not just waterproof, but fully submersible.

The STP9000 was also the first TETRA radio to feature Haptic Technology, significantly improving its key response for users working in heavy gloves.
