In an emergency situation, policemen, firemen and other rescue staff rely on their radio equipment. But can they? Officers don’t want to wait until the radio or the network fails in an action.
  
Mobile radio testing: 2303 Stabilock TETRA Mobile Station Tester
|
|
 The 2303 Stabilock is the first tester designed solely for the service of TETRA phones. Service managers responsible for the radio equipment use the affordable instrument to ensure that the radios are fully operational; this is particularly important for public safety and security organisations where lives may depend on proper communication tools. > more

Connecting without a connector: 4914 Antenna Coupler
|
|
 The antenna coupler complements the 2303 Stabilock and enables tests over the antenna, without the need for mobile-specific RF adapters. While typical test connectors bypass the antenna, testing with the 4914 Antenna Coupler ensures that the antenna is included in the test. > more

Base station testing: 2303 Stabilock with BS test option
|
|
Ensure that the base stations retain their high quality despite vast variations of temperature and humidity! With a new software option installed, the 2303 Stabilock can now take transmitter and receiver measurements at the antenna connector. > more

QoS, drive test, interoperability test: 8140 TETRA AirAnalyzer
|
|
 Find black spots and handover problems in the network, analyse the quality of service with a device that monitors the flow of communication between base station and the mobiles. Comprehensive PC software is available to support you in the post-processing of raw data, from message sequence charts to coverage maps. The 8140 TETRA AirAnalyzer is a necessary tool for both the network provider and the safety-conscious user group. > more

TETRA is not Tetrapol.
TETRA stands for Terrestrial Trunked Radio and is an open standard for Professional Mobile Radio applications, including communications for the public safety and security organisations.
The first version of the TETRA standard goes back to 1995. TETRA was standardised and is maintained by the European Telecommunications Standards Institute (ETSI), mainly in the ETS 300 392 (V+D) and ETS 300 396 (DMO) standards. The main technical branches of TETRA are the Voice+Data (V+D) and the Direct Mode Operation (DMO) specifications, where V+D defines basic speech and data communication over a network (base station) and DMO defines operation without a network (base station) involved, e.g. for emergency services in a tunnel.

Tetrapol is a proprietary standard for similar applications, but using a totally different technology (FDMA and GMSK as opposed to TDMA and pi/4 DQPSK). Introduced in 1988 to 1990 for the French police organisations, the Tetrapol standard is now available from EADS as a publicly available specification.
