Hytera is pleased to announce the launch of its TETRA E-Pack 100 digital wireless ad hoc networking device.

The E-Pack is an all-in-one radio, repeater and mesh node designed for fast and flexible deployments such as emergency situations. All three modes use just one frequency, greatly saving RF resources.

No infrastructure or cables are required, making it ideal for situations calling for a fast response. The battery-operated device ensures that when power supplies fail or TETRA networks are compromised, the E-Pack enables the emergency services to communicate using their existing TETRA handsets in direct mode with up to 10 hours talk time.

The E-pack can make and receive calls with other E-Packs or TETRA radios via a palm-microphone. It can act as a repeater to transmit a call to another device, portable Hytera E-Centre dispatching unit, or link up with a macro network. As soon as it is powered up the E-Pack automatically links up with other E-packs to form a self-configuring and dynamic ad hoc wireless mesh network.

Up to three hops are supported. If one E-Pack moves out of coverage or malfunctions, voice calls are automatically routed to another E-Pack to ensure link continuity and provide a self-healing network. The E-Pack offers adjustable RF power outputs of 1W/5W/10W.

The lightweight E-Pack (3.6kg) offers flexible deployment options including backpack, wall-mounted, vehicle and drone installation. It is highly ruggedised being IP67 protected against dust and moisture ingress and MIL-STD 810G certified for drop, shock and vibration resistance. It operates in temperatures from -30°C to +60°C.

A typical scenario would be a fire in a high-rise building, where coverage is not available due to the fire or lack of infrastructure. The firefighters’ E-Packs will seamlessly mesh together using ad hoc links as they move throughout the building. The E-Packs also support radio links to colleagues outside.
E-Packs are ideal for search and rescue operations over mountainous terrain, as the 10W output delivers wide area coverage. They can extend above ground coverage by providing a temporary signal extension and provide reliable communications for field workers, such as electricity or other utilities, working in remote locations.

The TETRA E-pack 100 is an excellent addition to any TETRA public safety system, as it ensures that even in the event of a total communications blackout all personnel can speak to each other using their existing terminals.
