Core Business Focus and Technologies

Dingli's primary mission is to provide end-to-end wireless network optimization solutions. This involves capturing and decoding the air interface data between mobile devices and base stations to identify network anomalies, drop calls, interference, and coverage gaps.

The company's core technologies focus on: * Multi-technology Decoupling and Testing: Enabling simultaneous testing across different chipsets (Qualcomm, MediaTek, HiSilicon, etc.) and network standards. * 5G NR Air Interface Analysis: Real-time decoding of complex 5G beamforming, massive MIMO, and network slicing parameters. * Unattended and Cloud-Based Monitoring: Transitioning traditional manual drive testing into automated, cloud-managed testing workflows. * Data Post-Processing Algorithms: Translating billions of raw network data points into actionable insights and network health scores.

Comprehensive Product Portfolio

Dingli's products are divided into four primary categories: Handheld/Walk Test Solutions, Drive Test Solutions, Autonomous/Fleet Testing Solutions, and Post-Processing & Big Data Analytics Platforms.

1. Handheld and Walk Test Solutions

These tools are designed for indoor, pedestrian, and hard-to-reach locations such as shopping malls, subways, office buildings, and airports, which account for a significant percentage of mobile data traffic.

• Pilot Walktour: Dingli's flagship handheld network optimization tool. It is an Android-based software solution installed on commercial smartphones. It supports real-time voice, data, and video stream testing. Key features include:

  • Multi-technology testing (5G NR, LTE-A, WCDMA, GSM).
  • MOS (Mean Opinion Score) testing for voice (POLQA/PESQ) and video (VMOS).
  • Built-in indoor mapping, allowing users to import floor plans and plot network parameters dynamically during a walk.
  • Direct integration with various test chipsets to pull low-level diagnostic logging information.

• Pilot Walktour Pack: A portable multi-device walk test solution. It integrates multiple smartphones running Pilot Walktour into a lightweight backpack or shoulder bag, managed centrally via a single tablet interface. This allows operators to benchmark different networks simultaneously under the same physical conditions.

2. Drive Test (DT) Solutions

Drive testing remains a critical method for analyzing wide-area coverage along roads, highways, and high-speed railways.

• Pilot Pioneer: A PC-based, multi-device, and multi-technology drive test and analysis software. It connects to various test terminals, scanners, and GPS receivers to collect detailed air interface logs.
  • Supports high-density multi-terminal testing (up to 30+ devices simultaneously).
  • Advanced real-time analysis windows for 5G NR beams, cell configurations, and throughput rates.
  • Support for RF sweep transmitters and receivers to perform baseline coverage mapping.
  • Flexible event-triggering mechanisms for automated testing sequences.

3. Autonomous and Fleet Testing Solutions

To reduce the high operational expenditure (OPEX) associated with manual field testing, Dingli offers automated, unattended testing hardware and software.

• Pilot Scout: A highly compact, robust, and autonomous test probe. These probes are designed to be permanently or semi-permanently installed in public transport (busses, trains, taxis), delivery fleets, or fixed monitoring stations.

  • Operating automatically without human intervention, they execute scheduled test scripts (web browsing, streaming, voice calls).
  • Equipped with GPS and cellular modules to upload test results in real-time to a central cloud server.

• Pilot Fleet Edge: A cloud-based centralized management platform. It allows engineers to remotely configure test plans, monitor the real-time status of Pilot Scout probes or active Pilot Walktour units in the field, push software updates, and automatically pull log files for analysis.

4. Post-Processing and Big Data Analytics

Raw data collected from walk and drive tests requires sophisticated analysis to locate systemic network issues.

• Pilot Pioneer Expert: A powerful desktop post-processing and diagnostic software tool. It digests massive quantities of log files collected from Pilot Pioneer and Pilot Walktour.

  • Provides detailed time-line correlation, map-view replays, and call flow decoding.
  • Built-in expert analysis algorithms that automatically identify and diagnose common network problems such as pilot pollution, missing neighbors, hardware failures, and high interference.
  • Customizable report generation engines for quick delivery of KPIs to stakeholders.

• Pilot Matrix: An enterprise-grade, web-based big data analytics platform. It aggregates data from multiple sources (drive tests, scanner data, and network element OSS logs) to provide a macro-level view of network performance.

  • Multi-dimensional dashboard rendering for executive viewing.
  • Geographic Information System (GIS) mapping for spatial network performance analysis.
  • Trend analysis tools to track network improvements or degradation over weeks and months.

Services Offered

Beyond its software and hardware product suites, Dingli provides professional technical and engineering services to support telecommunications ecosystems.

1. Network Planning and Optimization Services

Dingli deploys specialized teams of RF (Radio Frequency) engineers to assist operators during critical phases of network lifecycles: * Initial 5G Deployment Planning: Assessing propagation models and optimal site placement. * Network Tuning: Fine-tuning antenna tilts, azimuths, and power levels to maximize coverage and minimize interference. * Special Event Support: On-site monitoring and optimization during high-traffic events (sports, concerts, national holidays) to prevent network congestion.

2. Benchmarking Services

Dingli offers independent network benchmarking services. By deploying multi-channel drive test setups, they measure and compare the network performance of competing operators within a city, region, or country. These objective assessments help operators formulate competitive strategies and assist regulators in verifying license compliance and QoS mandates.

3. High-Speed Railway (HSR) Testing Solutions

Due to China’s massive high-speed rail infrastructure, Dingli has developed specialized testing services and configurations tailored to high-mobility scenarios. This includes adjusting test parameters to handle rapid Doppler shifts, frequent cell handovers, and signal penetration loss through specialized train carriages.

4. Technical Support and Training

Dingli maintains an active global support framework offering software maintenance, remote technical assistance, equipment calibration, and comprehensive training programs (both classroom and field-based) for RF engineers utilizing the Pilot series software.

Target Industries and Global Footprint

Dingli's primary client base consists of: * Mobile Network Operators (MNOs): Direct users of the software to manage their physical networks. * Network Equipment Manufacturers (NEMs): Utilizing Dingli tools to test and validate their base stations and core network equipment during development and deployment. * Regulatory Bodies: Assessing whether operators meet national broadband and telecommunication service level agreements. * Third-Party Subcontractors: Engineering service companies that execute drive testing on behalf of operators.

Through its extensive product line and continuous adaptation to cutting-edge wireless standards, Dingli Communications Corp. remains a critical enabler of the global transition to high-performance 5G networks and beyond.
