Cobham Wireless is the industry pioneer in the field of providing TETRA coverage solutions having delivered the first such product in 1997. Today, we have supplied thousands of TETRA coverage products into virtually every major public safety network in the world that uses the technology. We have one of the most experienced TETRA engineering and design capabilities in the industry and are regularly called upon by network operators, public safety systems integrators, base station manufacturers and public safety authorities to help solve TETRA coverage issues.
Cobham Wireless introduced the world’s first digital SDR (software defined radio) TETRA coverage products at TETRA World Congress 2009 in Munich. Based on our patented DSP (digital signal processing) technology our TETRA solutions provide extremely low delay and high selectivity filtering capability to enable systems to be configured precisely to the requirements of the individual public safety network and the local operating environment.
Our range of DSP (digital signal processing) TETRA repeaters provide coverage in small, medium, large and campus style buildings, inside tunnels, metros and remote or rural communities. In addition we have incorporated our industry-leading frequency and band shifting technology used in cellular products into TETRA. Thus our TETRA products include the ability to extend the reach of a base station into, for example, remote or rural environments. The use of such products dramatically reduces the number of base stations needed to operate a TETRA network and thus lowers capital and operating expenditure.
Our TETRA products can be used to provide coverage by themselves or as a feeder into a DAS (Distributed Antenna System). Being software based, new features and capabilities can be easily installed in the future. The products feature an innovative “time slot ALC” mechanism which reduces noise transmitted to the base station thus improving overall network performance and selectivity. Systems are easily configured either locally or remotely via a simple GUI web interface or using the AEM (Active Element Manager) system and are supplied in secure, robust and weatherproof IP65/NEMA 4 cases. In common with other public safety products our TETRA product range is of the highest quality and has been operating in many networks for over 10 years.
