Microwave communication technology, a key medium for long-distance network transmission alongside coaxial cables and optical fiber systems, has been in use for over half a century. Its digital microwave systems offer an economical solution for communication infrastructure, particularly in challenging terrains where optical fiber may be impractical or insufficient.

Core Technical Capabilities:

1. Wide Frequency Range Utilization: Effective planning and operation across frequency bands from 4 GHz to 11 GHz, with a focus on the 7–8 GHz defense communication bands.
2. Advanced Microwave Path Analysis: Utilizes microwave path analysis software for precise simulation, resulting in a low error rate and high system availability.
3. Adaptive Modulation Scheme (ACM): Adjusts modulation modes from QPSK to QAM to meet varying path conditions, ensuring adaptability and reliability.
4. Enhanced Spectrum Efficiency: Implements 512QAM to transmit over 300 Mbps within a 30 MHz RF bandwidth, improving spectrum utilization and data throughput.
5. Advanced Error Correction: Employs Forward Error Correction (FEC) and BCH techniques to reduce bit error rates, achieving performance comparable to optical fiber systems.
6. Adaptive Time Domain Equalization (ATDE): Utilizes high-performance, digital two-dimensional time-domain equalization to minimize inter-symbol interference, orthogonal interference, and multipath fading.
7. Diversity Techniques: Incorporates Space Diversity, Frequency Diversity, and Quad Diversity to mitigate path loss and enhance system availability.
8. Robust Protection Architecture: Features Hot StandBy and 1configurations for expanded capacity and error-free protection switching.
9. Adaptive Transmission Power Control (ATPC): Promotes frequency coordination and minimizes power consumption through adaptive transmission power adjustments.
10. Flexible Bypass Channels: Provides up to three E1 bypass channels for downlink traffic at relay stations and additional upload services.
11. Radio Equipment Manager (REM): Employs SNMP-based network management for centralized monitoring and control of the entire radio network, ensuring seamless integration with higher-level network management systems.
