About Sepura

Sepura is a global leader in the design, development and supply of TETRA (TErrestrial Trunked RAdio) digital mobile radios. These are secure communication devices dedicated to professional front-line services and first-responder personnel users, predominantly in the public safety sector (i.e. police, fire, ambulance and rescue), but also in the transport, military, utilities and commercial sectors.

TETRA technology facilitates reliable radio communications at all times and offers secure voice and data transmissions - free from the possibility of eavesdropping. It is mission critical and often life saving benefits such as these that are driving and accelerating the continued migration from analogue to digital communication networks. TETRA has now become the dominant and fastest growing digital Private Mobile Radio standard in the world and is present in more than 100 countries.

Sepura is focused solely on TETRA radio terminals and accessories. Our vision is to become the number one supplier of TETRA radios globally and we are making good progress in this strategic direction.

Based in Cambridge, England and employing some 300 employees, Sepura was admitted to the Official List of the London Stock Exchange on 3 August 2007.
