Telum selects software protocol stack APCO P25 from IntegrIT
Moscow, Russia — August 28th, 2012 —
IntegrIT Ltd, a DSP/VoIP design house announced that Telum, a R&D center of wireless systems design and development, has selected IntegrIT’s software programmable stack to enable APCO P25 FDMA functionality in next generation SDR (software defined radio) equipment.
APCO P25 is a modern radio telecommunication standard for UHF trunking based on frequency division multiplexing with channel bandwidth for 12.5kHz. The APCO P25 digital radiostation is backward compatible with analog FM radio stations. According to the standard, Common Air Interface (CAI) is used to enable voice and packet data exchange between portable, mobile and base stations made by different manufacturers and certified to work in APCO P25 radio networks. CAI consists of C4FM digital modulator/demodulator, a channel coder/decoder and an upper layer data transmission protocol. CAI implements the PHY level of digital radio.
“During the project, the IntegrIT team demonstrated their professionalism and high level of expertise in APCO P25. All scheduled works and milestones for the porting of the APCO P25 software stack on our target platform were completed in the shortest time frames“, said Alexey Kovalenko, Technical Director of Telum. “The world market of ready off-the-shelf licensable solutions for SDR is very close due to standards and we appreciate that a Russian R&D company is able to provide such competitive and comprehensive solutions”. “It is very noteworthy that Telum has selected our product which has already been deployed many times and fully tested“, commenting on this agreement by Alexey Nazarov, Technical Director of IntegrIT. “Usage of ready solutions always saves development time, shortens time to market and minimizes risks."
The IntegrIT APCO P25 software protocol stacks have been tested for interoperability and conformance to the standard and have been successfully working for several years in the equipment of well recognized radio manufacturers such as Spectra Engineering, Cimarron Technologies, and EMC Spa. IntegrIT’s APCO P25 CAI solution allows manufacturers to build APCO P25 inter-operable radio stations and add advanced features such as IP network support via DFSI (digital fixed station interface).
Implemented in proprietary algorithms, the suboptimal demodulation and decoding of the APCO P25 signal results in high receiver sensitivity, wider communication range and higher reception quality in severe noise environments. The software programmable stack can be easily scaled and configured to work in portable or mobile stations, repeaters or base stations. The solution is cross-platform and many popular DSP architectures are supported. This allows flexibility in hardware design and rapid software porting.
Along with APCO P25 CAI, IntegrIT offers similar solutions for the competitive trunking radio standard – DMR (digital mobile radio). It is European alternative to APCO P25 that is based on TDMA channel access.
