Product roundup: Latest TETRA equipment

Stop Noise making waves in TETRA

The new Multi Handset from Stop Noise combines audio, data and image features in a single device for radio terminals of digital TETRA networks.

It features an RFID reader and biometric identification methods such as fingerprint reading and face recognition to combine data and imaging features integrated to a traditional speaker microphone.

According to Stop Noise, the Multi Handset will be available in several different versions, all of which will include the normal audio functionality and good ergonomics of a speaker microphone in addition to a host of other features. These include a keypad for controlling the radio terminal, an accelerometer for man-down alert, a microSD slot for internal memory and a USB interface.

Stop Noise says that customers will also be able to choose the most suitable data collection technology such as the camera barcode reader, RFID reader or fingerprint scanner. The beauty of the device lies in its ability to send acquired data via TETRA network to different customer specific applications and to experts for further processing.

Cassidian’s TETRA THR9i radio

Launched at the PMR Expo in Cologne, the TETRA-based THR9i from Cassidian is a handheld radio aimed primarily at those working areas of increased risk.

Designed to give users peace of mind, its Lifeguard feature, known as ‘man-down’, is able to send a distress message to a predefined number at the touch of a button.

Once activated, man-down is able to sense if the radio stops moving or remains horizontal for too long, automatically triggering an alert. Should the user fail to respond, the radio automatically activates an emergency call and sends its coordinates to a predefined destination over the TETRA network.

The device also features a GPS-based service called ‘Where are you’, which displays on calls and allows users to see exactly where team members are while also allowing these to be saved as waypoints for later use.

The device comes with IP65 classification meaning it is highly resistant to both dust and water, while a new improved metallic chassis and front cover design protects it against shocks. The THR9i is also able to receive and host applications that can be customised to meet specific needs thanks to an enhanced memory and Java support.

A large QVGA colour display means data can be captured at a glance, while its radio offers clear sound and excellent audibility for voice calls in noisy environments. In addition to this, a high capacity battery, offering as high as 4600 mAh performance, ensures the device will operate for extended periods of time even under intensive use.

Motorola ensures the gloves are kept on with MTP830 S TETRA radio

The MTP830 S TETRA radio from Motorola is aimed squarely at the testing environments those within fire departments are forced to endure.

Featuring a large, simplified keypad – ideal for use when wearing gloves – and IP55 certification, the device has been engineered to resist heavy water streams and dust, critical for firefighters responding to emergency calls.

Benefiting from new features such as a simplified keypad for quick access to radio functions like group call selection, the MTP830 S is based upon the company’s existing interface for TETRA radios.

Easily distinguishable by its robust design, it also packs an enlarged multifunction rotary button on the radio, making it easier to regulate volume and change TETRA talk groups.

For those situations where a firefighter may be injured and/or unable to move, emergency calls can be immediately made with the MTP830 S through a built-in sensor, while an integrated GPS receiver provides the necessary location information to assist in
managing responses.

The device also comes with ETSI Class 3L (1.8W) transmit power and increased receiver sensitivity for improved coverage in TMO and DMO operations, ensuring officers can communicate over a wider area while delivering improved coverage in buildings or built-up areas.

Small is beautiful - Jaybeam Wireless antennas

The 5880903 Tri-band, XXX-Pol, Tri-Sector Antenna from Jaybeam Wireless is a compact TRIO antenna offering multi-band capability (880-960/1710-2170/1710-2170MHz) with 17.5/17.2/17.3dBi gain and 65° azimuth beamwidth.

With its high functionality, low weight, low visual impact design, and each sector featuring azimuth panning of ±15° capable of remote electrical tilt (RET), the antenna is ideal for challenging zoning locations.

Jaybeam says that electrical downtilt can be controlled separately for Low Band, High Band White and High Band Blue.

This can be done either manually without the need for tools or remotely via the module inserted at the bottom of the antenna, with one single module controlling the tilt of each band without the need for daisy chain cables between bands or any additional length being added at the bottom of the antenna. For RET control, the transparent cap must be in place and locked, with the tilt
angle indicator always remaining visible and the antenna retaining manual tilt control.

Rohde & Schwarz IQR digital I/Q data recorder

The R&S IQR digital I/Q data recorder from Rohde & Schwarz is capable of holding 1Tbyte data for analysis and can record, store and replay digital RF signals loss-free and in real-time over an I/Q interface developed by the company.

When used in combination with RF scanners, generators and network analysers, the recorder becomes a high-performance, continuous analysis system for digital RF signals.

The system, which should be of particular benefit to users in broadcasting, mobile radio, aerospace and defense and the automobile industry, becomes a high-performance, continuous analysis system for digital RF signals when used in combination with RF scanners, generators and network analysers.

The compact device, in half 19-inch format, currently offers transmission rates of up to 66-Msample per second and comes with a robust, interchangeable solid-state drive with 1Tbyte of storage capacity plus a recording rate
of 270Mbps.

This means it is ideal for use in drive tests in broadcasting and mobile radio networks, while for instrument tests or electronic component testing the recorder can be used to supply previously generated test signals. Furthermore, broadband spectra or sporadic signals can be recorded in real-time for later offline analysis.
