TWC product roundup

New digital band repeater from Axell Wireless (left)

Axell Wireless unveiled the BSR438 digital band selective TETRA repeater in Budapest. Based on the company’s SDR (software defined radio) and digital filtering technology, the BSR438 does not require hardware upgrades and can be configured remotely using software updates. The launch is an extension of Axell’s range of digital TETRA repeaters, which includes the existing channel selective CSR438.

The BSR438 TETRA digital repeater is designed to support public safety networks and PMR (Professional Mobile Radio) systems for high security applications such as Metro networks or the oil and gas industries. Its broad frequency capability allows the BSR438 to operate from 380MHz to 470MHz in bands of up to 20MHz in bandwidth.

Equally, a narrow band part of the spectrum can be selected through a simple GUI interface. Being a band selective unit, the BSR438 is well suited to applications that require more than eight channels to be amplified. In addition, thanks to Axell’s DSP architecture, the BSR438 can be converted by a simple upgrade in software to Axell’s channel selective product, the CSR438.

Sepura unveils intrinsically safe STP8X radio

Sepura used the Congress to announce the addition of intrinsically safe products to its range of TETRA radios. The new launches include the STP8X device, which offers features normally only available on Sepura’s flagship STP8000 device range.

These include missed event notifications, a microSD image viewer for looking up hazardous material data, and a display that offers crystal clear viewing under all conditions, including harsh sunlight. The device also offers extended battery life, a feature not normally associated with ATEX/IECEX radios.

Sepura expects the device to build on its position in hazardous gas and dust sectors such as fire, oil and gas exploration and opencast mining where intrinsically safe ATEX/IECEX certified products are required.

DAMM completes indoor base station range from BS411 25W

DAMM announced the completion of its existing indoor base station portfolio at the show with the introduction of its BS411 25W high power indoor base station. Designed for use in networks where high traffic capacity is required and where terminals operate with more than 1.8W output power, the base station can support up to eight carriers.

Features include fully IP-based connectivity so remote supervision and diagnostic operations, test, control, setting and software updates and file transfers are all enabled.

In addition, operators gain further advantages since the base station’s embedded operational and maintenance system is accessed via a Windows desktop. Reduced power consumption is achieved by supporting discontinuous transmission – where only active transceivers need power – until traffic load requires more carriers to be on air.

Bluetooth headset solutions from Savox

Savox Communications previewed its new range of Bluetooth solutions for the professional radio market at the Congress. These included the Savox Communications Professional Bluetooth noise reducing headset, which is designed to provide the convenience of handsfree operation with a range of professional Bluetooth radios. The ergonomic design means it is secure and comfortable to wear for long periods of time and can be used with glasses and gloves.

A feature of the headset is the foam ear tip that provides high performance hearing protection capabilities which block all background noise from the ear when the product is in operation. It is ideal for the professional user who needs a headset with hearing protection for long periods on a daily basis such as police, security, industrial, maintenance and transport professionals who are in active situations.

Cassidian’s mini TB3p base station plugs the gap

Cassidian used the event to introduce its TB3p TETRA base station, which it claims can help eliminate the last gaps in radio network coverage. The TETRA base station, which is about the size of a standard laptop PC, offers similar features to Cassidian’s larger TB3 and TB3c, but with power consumption of only 40W – about 10% of that of a conventional macro base station.

The company expects the most popular application for the TB3p to be for indoor coverage in large public buildings, shopping centres or indoor car parks. It is also an extremely cost-effective way of filling coverage gaps. The TB3p can also be used as a standalone base station to provide hotspot coverage in places that the network may not reach.

The TB3p can help TETRA network operators and owners save money as it does not need a costly site, and can adapt to the transmission network that is available: it can use conventional
time-division multiplexing (TDM) transmission, but also Internet Protocol (IP) transmission.

Unimo displays MU-1500MD TETRA data modem

Unimo showed off its MU-1500MD TETRA data modem at the Congress. It operates in the 380-400MHz and 410-430MHz bands. Features include: status message; SDS TL140 Byte/frame; PPP connected packet data mode; auto power – on reset; PEI interface with at-commands; and an option for a GPS location report on demand.

The modem can be used for a range of remote control applications including; tele-metering and tele-control applications; automatic meter reading; and supervisory control and data acquisition applications. The modem is designed to operate in temperatures ranging from -20°C to +55°C.

CeoTronics shows off CT-ClipCom Ex device

CeoTronics demonstrated its now ATEX-approved CT-ClipCom Ex, an intrinsically safe device in accordance with European standards EN 60079-0:2006 and EN 60079-11:2007. Conforming to the high protection class ‘II 2 G Ex ib IIC T4’, the device is suitable for approximately 98% of ATEX scenarios.

The ATEX certification applies to both versions of CT-ClipCom: CT-ClipCom Earmike with an ear microphone and CT-ClipCom Boommike, which has a flexible swan neck microphone. The boommike version comes with the company’s new Flexboom, which is lighter and more robust. It keeps its shape better and does not bounce back when newly positioned.

As standard, both products come as monaural versions and can also be obtained as binaural communication systems.

CT-ClipCom Earmike has also been EC type-approved as hearing protection compliant in accordance to EN 352-2. That removes the need for workers in those situations from having to wear heavy sudorific ear muffs.
