Background
The Operation and Maintenance Division (OMD) of RCY was using an MPT1327 system. The obsolete system was suffering from traffic jams due to the increasing business of the OMD, the coverage was not big enough to cover the expanding area of RCY and the voice quality dropped dramatically at the edge of the coverage. The lack of spare parts and technical support made it urgent to upgrade the system. Meanwhile, according to the latest regulation and requirement of HCIS (High Commission of Industrial Security) of KSA which belongs to the Ministry of Interior, the new system must support high reliability with redundant design, high safety with encryption, visualized dispatching, and voice recording for at least 12 months.
Solution
After a careful study and analysis of RCY’s requirement and the HCIS’ regulation, as well as a detailed site survey, Hytera proposed a state-of-the-art DMR Tier III Trunking system and stood out from the vendors after strict technical and commercial evaluation. The HCIS-compliant Hytera DMR Tier III Trunking system is composed of two base stations and an MSO (Mobile Switching Office) with all the
major components in redundancy design and hot stand-by mode to secure its reliability.
Benefits
The Hytera DMR Trunking Lite base station adopts the Triple Diversity Receiving technology to enlarge the coverage and increase dynamic receiving sensitivity. Due to the limited frequencies, Hytera offered the Simulcast Trunking technology so the two base stations used the same frequencies without interfering with each other and the terminals can roam seamlessly between them. Dual Authentication stops intruders and AES Encryption protects the system from eavesdropping. Besides crystal clear digital voice, the system has versatile data services like messaging, GPS, AVL (Automated Vehicle Location) and voice recording, etc. The dispatcher can know exactly where the staff/vehicles are located & moving by using the GPS and AVL function thus accomplishing visualized dispatching. All the voice communication in the system is recorded and can be played back for historical check and truth recovery.
The Hytera terminals are rigid and reliable, complying with IP67 (fully water and dust-proof) and MIL-STD-810G. Since RCY needs voice communication all the time, a smooth migration plan was designed and implemented with the repeater of the old system shut down one by one and the new base station’s repeaters turned on gradually so the end-user experienced zero downtime.
