In point-to-point (P2P) and point-to-multipoint (PtMP) microwave networks, high-gain parabolic antennas are essential for long-distance, high-capacity wireless transmission. Yet private network operators, power and oil-and-gas companies, emergency communications providers, and smart mining integrators all face the same operational challenge: costly return visits to towers for antenna realignment are steadily eroding project margins.
Why do conventional fixed parabolic antennas need repeated manual realignment? And how can a different antenna architecture eliminate the need to climb towers simply to correct antenna misalignment?
Drawing on its expertise in maritime and land-based auto-tracking antennas, KINGSAT has adapted high-precision maritime tracking algorithms and rugged hardware for terrestrial installations. The result is the MP Series of pole-mounted auto-tracking microwave antennas, designed to change how fixed microwave links are maintained.
1. The Challenge: Antenna Misalignment and Rising OPEX
High-gain parabolic antennas enable microwave links spanning several to tens of kilometers, especially at higher frequencies. But higher gain generally comes with a narrower beamwidth. This makes precise antenna pointing more vulnerable to movement and deformation in exposed tower installations.
• Tower movement and ground settlement can shift the antenna off target. Take the KINGSAT MP7, a 72 cm parabolic antenna: its stated gain is 32 dBi, with a beamwidth of just 3.4°. A pointing error of more than 1°–2° can substantially reduce received signal strength (RSSI) and signal-to-noise ratio (SNR), potentially causing packet loss or a complete link outage. Strong winds, thermal expansion and contraction of metal towers, and gradual ground settlement can all shift a fixed pole-mounted antenna away from the optimal main-beam direction.
• Tower-climbing maintenance is costly and time-consuming. Once misalignment disrupts a link, specialist technicians may need to travel to the site and work at height. Labor premiums, transport and test-equipment rental can push a single troubleshooting visit into the thousands—or even tens of thousands—of renminbi. In remote locations or severe weather, safe tower access may be delayed, extending downtime and disrupting private network operations.
• Manual alignment is slow and difficult to reproduce consistently. Conventional fixed antennas require engineers to adjust mounting hardware by hand, often using portable measurement equipment high above the ground. Gusty conditions make fine adjustments harder, while operator-dependent variation can prevent the link from reaching its optimal performance.
2. The Solution: KINGSAT MP Series Pole-Mounted Auto-Tracking Antennas
To address the limitations of fixed antennas, KINGSAT has brought its maritime tracking expertise to terrestrial towers and poles. The MP Series features a two-axis (2-axis) positioning system and includes the MP4 and MP7 models.
2.1 Intelligent Fine Adjustment and 60° Automatic Scanning
• ±15° intelligent fine adjustment. A precision two-axis servo drive enables automatic azimuth and elevation adjustments within ±15°. If wind loading or tower deformation shifts the mounting pole, the antenna can compensate for changes in pointing direction to help maintain alignment with the main beam.
• 60° automatic alignment scan. During initial installation or post-disaster restoration, integrated GNSS and electronic compass modules help determine the antenna’s relative pointing direction. The system can automatically scan a 60° sector to locate and align with the remote station—reducing the need for painstaking manual aiming.
2.2 Industrial-Grade Hardware Built for Reliability
For stable, long-term operation in exposed outdoor installations, the MP Series uses an industrial-grade hardware architecture and carefully selected components.
• Control and positioning. Automotive-grade control chips and high-precision GNSS modules support positioning and servo control, with millisecond-level response claimed for the control system.
• Drive and fastening system. Industrial-grade high-strength drive belts and wedge-lock washers are designed to resist loosening caused by wind-induced vibration.
• Environmental protection. A high-transmission, UV-resistant radome provides protection for the antenna. The stated enclosure rating is IP56, with an operating temperature range of −30°C to +70°C.
2.3 Five-Second Telemetry and Remote Maintenance Without Tower Climbs
• Status telemetry every five seconds. An integrated network management module supports five-second reporting intervals for antenna status, including azimuth, elevation, received signal strength (RSSI), and device health information.
• One-click remote realignment. Via a web interface or mobile app, maintenance teams can monitor antenna status across the network and trigger an automatic realignment procedure when a node drifts off target. Under suitable conditions, the process can complete within seconds, potentially avoiding a return trip to the tower for alignment.
3. The Benefits: Lower OPEX and Stronger Network ROI
For private network operators, energy companies, and systems integrators, the MP Series can reduce the cost and operational disruption associated with manual antenna realignment.
• Lower OPEX: fewer alignment-related tower climbs. By reducing the need for repeat tower visits caused by pointing drift, automated realignment can cut maintenance expenses. For example, a private network with 20 microwave nodes could save tens of thousands to hundreds of thousands of renminbi annually in tower-access and alignment costs, depending on local labor rates and how often realignment would otherwise be required.
• Better link availability and SLA performance. Automatic pointing compensation and realignment can help restore links after wind-related movement, reducing reliance on site visits that may take days to arrange. In favorable conditions, recovery can be much faster than manual troubleshooting, helping limit service disruption.
• Faster installation. Instead of performing every fine adjustment manually with specialized alignment instruments, technicians can mount the MP Series antenna, power it on, and use its automated scanning and alignment functions. The original installation estimate indicates a potential reduction of more than 80% in deployment time per node, subject to site conditions and the measurement method.
• Centralized digital operations. Five-second telemetry updates and remote controls give network teams visibility into antenna status and the ability to initiate realignment from a control center, reducing travel and high-risk work at height.
4. Applications: Microwave Backhaul for Critical Private Networks
With automatic alignment and a rugged design, the KINGSAT MP Series is suited to challenging terrestrial deployments where reliable, high-capacity microwave connectivity and reduced site visits are priorities.
• Power, oil and gas networks. Microwave backhaul between transmission-line monitoring sites, pipeline inspection stations, and wind farm towers, including locations subject to strong winds and tower movement.
• 5G-NTN and operator emergency sites. Wireless backhaul for private 5G networks and temporary or emergency base stations, supporting rapid pole-mounted deployment and automatic link alignment after an outage.
• Smart mining, water infrastructure, and border monitoring. High-capacity wireless connections for mine sites affected by terrain movement, elevated reservoir surveillance locations, and remote border-area facilities where access is difficult.
Conclusion
In networks where uptime and operating costs matter, repeated and hazardous tower climbs for antenna realignment should not be accepted as an unavoidable expense. With ±15° automatic fine adjustment, industrial-grade construction, and remote network management, the KINGSAT MP Series offers a practical way to reduce alignment-related fieldwork and improve microwave network maintainability.
For operators and integrators looking to build reliable, lower-maintenance microwave networks, the MP Series brings automatic alignment and remote control together in one pole-mounted platform.
