Hytera Provides Hytera DMR Trunking Pro for the CNPC HeadquarterChina National Petroleum Corporation. China’s largest oil and gas producer and supplier, as well as one of the world’s major oilfield service providers and a globally reputed contractor in engineering construction. According to the report, the current market values of CNPC reached $329.3 billion (up to March 31, 2010), with which it took a top spot in the nanual FT Global 500 list, being one of the world’s most valuable listed companies. 

With economic development, the demands for oil & gas and relates products are growing continuously. The scale of the oil & gas company continues to expand with more and more detailed division. In this point, the company demands more for the commanding and coordination in the work. For this reason, the converntional communication system can no longer meet the communication demands of daily work.

In 2007, CNPC and Beijing Changping District Government signed a strategic cooperation framework agreement on the construction of a leading oil & gas industry base that integrates scientific and technological innovation, product development and manufacturing. Total construction scale of the projectis 1.5 million square meters, It aims at establishing CNPC into a comprhensive international energy company.

The Challenge

  • hytera-image

    CNPC Science and Technology Park Project is of A12 block, including 1 basement, 11 floors above ground and 3 floors for podium. 1 basement is used as the garage, equipment room and storage room and constructed in two phases. The total construction area is over 200,000 square meters with the ground floor area of 165,398.6 square meters and underground construction area of 39081 square meters.

    Efficient Science and Technology Park requires a high-performance communication system to support its work. For CNPC, it demands to achieve unified dispatching and individual call, group call, text message, free grouping requirements and other practical communication functionalities for all the subordinate departments of the enterprise. Under this condition, it proposes higher demands for full-featured and highly scalable communications solutions. And digital communication system is preferred for stronger dispatching and advanced grouping.

The Solution

Fully understanding what the customer demands, Hytera proposed a DMR digital trunking communications for CNPC.

DMR digital trunking communication system is a professional wireless communication system with shared channel by multi-user and multi-sector and can dynamically manage and use these channels. The system is mainly used for command and dispatching communication and its superiority greatly lies on rapid response, easy to use and multi-level dispatching in a wide range of wireless communication.

Hytera established a digital trunking system with 4 carriers 8 channels by utilizing TDMA dual time-slot technology for CNPC Science and Technology Park. 1 DMR trunking base station, 4 digital trunking mobile terminals and 50 digital portable terminals were deployed in the system.


The Benefits

1.Strong anti-interference capability, superior audio quality and long communication distance.

2.Doubled communication capacity realized by TDMA technology.

3.Various call types, including individual call, group call and all call, together with flexible grouping.

4.Powerful management functions as system parameter setting and user information management.

5.High channel efficiency with dynamically allocated and managed channels, and high system stability with dedicated digital signaling channels.

6.Modularized system design for powerful dispatching and excellent scalability, enabling the users to expand the system easily once the users increase in the future.
