Hytera Mobilfunk expands the TETRA radio system of the security authorities in Macedonia
Hytera Mobilfunk GmbH expands the existing TETRA radio system in Macedonia by 26 base stations, exchange nodes and state-of-the-art IP technology. The network is used by the Macedonian security authorities for public safety
Together with the partner Nokia Siemens Networks (NSN), Hytera Mobilfunk GmbH delivered the TETRA radio system of the security authorities in Macedonia as early as in 2008, then still under the name of “Rohde & Schwarz Professional Mobile Radio GmbH”. The first installation of the network comprised 42 base stations, redundant exchange nodes and network management features as well as control centre technology made by NSN. In 2012, Hytera Mobilfunk GmbH was awarded the contract to expand the network by further base stations within the context of a tendering process to augment the service area with ACCESSNET-T IP.
The network expansion comprises 26 TETRA base stations of the type DIB-500 R4.1, a completely IP-based TETRA exchange IP Node as well as workstation computers to administrate the radio system. In addition, the existing control centres were modernised and provided with new features (GIS/AVL).
The special feature to be emphasized is that with ACCESSNET-T IP, the new network constituents are completely networked with each other via a completely IP-based network. E1-links can still be used in the existing network. The link between the new network segment and the existing network is implemented by a CS/IP bridge that permits Hytera’s customers to expand their existing networks with the state-of-the-art ACCESSNET-T IP at any time.
The project handling division of Hytera Mobilfunk was able to implement the installation of the network as well as the integration of the new network elements at the end of 2012, thus beating the customer’s schedule by two months. Apart from delivering the TETRA infrastructure, Hytera Mobilfunk GmbH was also responsible for rendering the entire location fit for the expansion (mast,service room). Since the acceptance test, the TETRA system has been operating in test mode and will go live at the beginning of February in the presence of high-ranking EU representatives.
