Delivery of Hytera Integration Project

Project Management

Hytera project management is the professional management service provided to customers for Hytera system integration delivery projects during the whole process or in the phases of survey design, network planning, factory acceptance, supply logistics, project implementation, system debugging, network optimization, delivery acceptance, and after-sales O&M.

Delivery Management Process


1 Site Survey
Confirm the installation environment of the pre-selected site, provide the basis for network planning and site selection, and improve the ease of installation of system equipment.

2 Coverage Test
Predict the coverage effect of the entire network, provide accurate data for network planning, and ensure proper construction of the entire network and maximum coverage.

3 Frequency Test
By testing the site electromagnetic and the interference of pre-allocated frequencies, master accurate frequency data, and effectively and properly allocate frequency resources to avoid interference to the system operation and electromagnetic impact between the systems.

4 Engineering Design
Based on characteristics of the sites, output construction drawings and engineering materials list to improve the system installation, achieve unified layout, unified standards, unified process, and unified quality, ensure proper operation of the system, and enhance the maintainability.

Hardware Installation

1 Site Survey
· Central control site installation
· Fixed base station installation
· Mobile site installation

2 Debugging
· Link debugging
· Software debugging

3 Data Configuration

Network Optimization/Delivery Acceptance

Obtain optimized performance by using hardware or software technologies, such as parameter setting.

1 Network Optimization and Function Demonstration
Relevant personnel of the project attend the function demonstration and confirm the demonstration results.

2 Training, Preliminary Acceptance, and Trial Run
The training is provided by Hytera professional training instructors mainly on the system, maintenance, and terminal.
The preliminary acceptance of the project preliminarily inspects all the work of the system within the scope of the project. If the preliminary acceptance is passed, the project enters the trial run period.

3 Data Transfer
Prepare project completion data and submit it to the customer.

4 Final Acceptance
The final acceptance inspects the system after the trial run period, and confirms the acceptance result.
