Aprisa SR provides secure, robust point-to-multipoint communications for Ministry of Defense first responder paging network

The Ministry of Defense of the Republic of Slovenia (MORS) operates a nationwide pager system for emergency 112 / 911 calls, with 13 regional centres throughout the country. 4RF Communications and its local partner IT-100 are replacing the pager backhauling network in the Gorenjska region of Slovenia.

The legacy analogue system used to backhaul the POCSAG paging traffic was very slow and did not provide even a basic level of encryption. In addition to improving the speed and security of the network, the chosen solution needed to be installed easily, without the need for repeat visits, since many of the paging transmitter stations are located in remote areas with altitudes of up to 2000 metres. It also needed to be sufficiently robust to cope with the challenging environmental conditions, with temperatures often reaching well below freezing.

IT-100 commenced deployment activities in December 2010, using the Aprisa SR in the 400 MHz UHF licensed frequency band. Over the three month period to the end of March 2011 a total of 59 Aprisa SR radios were deployed, and a further 19 are currently being deployed. All the radios were deployed by IT-100 without any need for support from 4RF Communications

The Aprisa SR is perfect for long distance UHF links in mountainous areas. It is simple to install and programme, and provides good security and high robustness.
