• Extend Cross-border Communication

    | Case Study

Mal-Tel, One of Malaysia biggest operators, has provided a professional communication system in Malaysia for 18 years. His network covers the state territory of Malaysia, consisting of the most area of the Malay Peninsula in the west and the Malay part of the Borneo island in the east. The business covers transportation, oil & gas, ports, hospitals, shopping malls and other industries.

Challenge or Demands

They wanted to upgrade their communication system for providing better services for industry and commercial customers with higher requirements:

  • High efficiency of frequency and spectrum: Business increases greatly but the old analogue technology can't provide more capacities based on the current frequency resource
  • Stability of system: Improve the system stability to ensure the 24 hours communication service
  • High OPEX: There are still lots of analogue systems running, and the cost of operation and maintenance is very high
  • Network coverage optimisation: Large area coverage and high capacity can reduce OPEX and enhance ROI (Return on Investment)

Solution

After analysing the technical requirements, Hytera proposes the professional operation solution based on DMR Digital Trunking Pro. The Hytera system reduces maintenance cost. To guarantee the system stability, Hytera provides a variety of network elements redundancy solution. Hytera adopts BSCU (Base Station Controller Unit) Standby backup mechanism. To ensure normal operation of the BS, as many as two BSCUs with same configurations can be used in one BS. If the master BSCU fails, the slave BSCU will take over its tasks immediately.

The total network configuration is the following:

  • 2 Control Centres
  • 1 Dispatcher System
  • 17 Base Stations
  • 10.000 Terminals

The DMR Pro System is IP-based architecture, which enables flexible networking and low requirements for the real-time link. The equipment can be deployed flexibly in the system, allowing the network node to be added or deleted easily. The operator had deployed the Hytera DMR pro system in phase one, and they plan to gradually extend system in 2015 and 2016.

Values brought by Hytera

  • BSCU (Base Station Controller Unit) redundancy design to ensure system availability
  • Improve network security with Athentication, ESN check, Group attachement features
  • GPS information transmission via dedicated channel without affecting voice service
  • Reduce customers' maintenance cost
  • Fast terminal configuration via OTAP (Over The Air Programming) feature
