Hytera is currently adapting LTE for use in the Professional Mobile Radio (PMR) sector and it showcased its future outlook for broadband PMR at this year Critical Communications World in Paris (21-24 May 2013).
Hytera already offers PMR solutions with higher data throughput based on TETRA Release 2 and TEDS (TETRA Enhanced Data Services) to satisfy the growing demand for data capability.
TEDS satisfies many mission critical data applications including picture transfer and even video. But for really demanding applications like high-definition video and other kinds of broadband data applications, the integration of LTE in TETRA is of high interest for public safety and also industrial users, Hytera said.
The present Hytera setup consists of an LTE eNodeB, a TETRA base station and an ACCESSNET-T IP core, which provides PMR services to smartphone-based LTE terminals and TETRA handheld radios.
Initially LTE is planned to be applied for pure data-centric applications, but with this setup Hytera demonstrated that even PMR voice services can be realized over LTE today. Group calls with priorities, text messaging and video over LTE are also supported.
Hytera noted that broadband helps to increase the situational awareness of personnel in the field or at the command centre. Similar to the public mobile radio industry, ‘apps’ will also enter the PMR segment and are the basis for the development of customer tailored tools which support day-to-day operations.
Hytera successfully completes IOP tests with ACCESSNET-T IP infrastructure
Hytera Mobilfunk finished the official multi-vendor interoperability test session with its TETRA system ACCESSNET-T IP and all relevant terminal manufacturers by the end of April 2013. Testing was conducted between 14 January and 13 March 13, as well as 22 and 26 April at Hytera’s testing facility in Bad Münder, Germany.
Interoperability testing ensures that terminals and infrastructure are in accordance with the TETRA standard. The current test session covered the Trunked Mode (TMO) and all related features of the air interface.
The final Certificates and Test Reports are expected to be published on the TETRA Association website by 28 June and 5 July 2013.
TETRA Interoperability testing and certification is carried out on behalf of the TETRA Association by ISCOM (Istituto Superiore delle Comunicazioni e delle Tecnologie dell'Informazione - laboratory of the Italian Communications Department of the Ministero dello Sviluppo Economico).
