The H-4855 is a short range Personal Role Radio (PRR) developed by Selex Communications 1 in the UK in 1999 and introduced for world-wide military use in 2002. The radio is used by Special Forces (SF), reconnaissance squads and infantry sections for direct tactical soldier-to-soldier communication. Although the radios are not protected by means of voice encryption, they are classed as LPI (Low Probability of Intercept) and LPD (Lower Probability of Detection) devices. In the US, the H-4855 PRR is known as AN/PRC-343 2 and as Integrated Intra-Squad Radio (IISR).


The radio operates in the 2.4 GHz band and uses spread spectrum technology. It weights 1.5 kg and is powered by two 1.5V AA-size penlight batteries, allowing 20 hours of continuous use. Being a low-power device it has a range of just 500 metres, but works well through the thick walls of a building. The PRR is used by all British Forces, some US forces and even by UN peace keeping forces. The device is typically issued to every member of an eight-person infantry section. A separate wireless Push-To-Talk (PTT) unit with a 2m range is available as an option.


The H4855 PRR was originally developed for the UK's Bowman Integrated Communications System but was spun off in 1999 so that it could be implemented more quickly. The first 45,000 units entered service in 2002 and although they are not compatible with the rest of the Bowman system 3 , they have revolutionised intra-squad communications and small-unit tactics [2]. The standard PRR was succeeded in 2005 [3] by the Enhanced & Encrypted Personal Role Radio or EZPRR which provides AES128 encryption and enables secure voice and data communications.
