CCW 2014: Teltronic unveils new TETRA-LTE infrastructure

Teltronic introduced its new eNEBULA TETRA/LTE infrastructure at CCW, as well as unveiling a mast-mounted base station, two new portable base stations and the new HTT-Lite TETRA covert handheld radio.

Teltronic has developed its own LTE technology independent of third parties, which is aimed at mission critical users. The ‘evolved NEBULA’ solution is based on its existing NEBULA TETRA architecture and natively incorporates LTE technology in its design to complement its narrowband capabilities.

The LTE technology can be seamlessly integrated into existing NEBULA networks in a cost-effective manner, boosting the data capabilities of narrowband systems, the company said.

The new core equipment of the eNEBULA infrastructure provides TETRA + LTE services in a single network design. With evolved NEBULA, TETRA and LTE share the same core equipment, based on the latest hardware components and operating systems, which optimises CAPEX and OPEX. Network management is also performed from a unified network management system.

New TETRA base stations
On the radio access side, Teltronic launched an IP66 outdoor eNodeB that shares the same mechanical design as its TETRA mast-mounted base station (MBS). The Teltronic LTE MBS can cope with all the required components of the eNodeB in a single box. It can be installed on the communications tower, delivering 10 + 10W with MIMO capabilities.

Teltronic launched two other types of base station at CCW. The portable base station (PBS) is a wheeled unit designed to be easily carried by a single person. Each PBS is made up of one TETRA carrier, which can be expanded with an extra unit to provide 2-carrier coverage. When linked to an existing eNEBULA system, the PBS works as an additional base station of the network, whereas if neither connection nor fixed system are available, the PBS can operate as a single site TETRA system without requiring any additional components. Optionally, the PBS can consist of an LTE eNodeB instead of a TETRA carrier.

The deployable base station (DBS) is designed to provide quick installation to provide coverage where it’s needed or to increase network capacity when facing emergencies. It incorporates telescopic legs enabling the unit to be raised in case of flooding or irregular terrain.

The DBS can be adapted to different configurations: two TETRA carriers (which can be expanded to four carriers using an additional DBS), a TETRA carrier and an LTE eNodeB in the same box or even two LTE eNodeBs in a redundant configuration. Both types of base station are designed to operate in temperatures from -30 to +60 ºC and boast IP-66 protection.

HTT-Lite TETRA radio
The new IP67-rated HTT-Lite covert TETRA radio (pictured, above) is just 102mm long, but delivers location services based on a built-in GPS receiver and still features advanced TETRA services such as DGNA, ambience listening, air interface encryption and call authorised by dispatcher, among others. The HTT Lite joins the existing 3W HTT-500 TETRA hand portable. Teltronic indicated that other new handheld radios will be released in the coming months.
