Hangzhou, China – CroSkylink Corporation has successfully demonstrated its long-range communication technology's ability to reliably support drones beyond 150 kilometers, conquering one of its most challenging real-world tests to date across the dramatic elevation shift between Longwang Mountain (1,587m) and the Hangzhou Bay dike (15m).
This demanding test corridor, spanning over 150km with a 1,572-meter elevation difference, simulated the extreme geographic obstacles often encountered in industrial drone operations. Crucially, 150km represents a major operational milestone for targeted applications, not the limit of CroSkylink's technology.
Key Test Parameters & Performance:
-
Frequency: 1.4 GHz
-
Antennas: Standard 5dBi (Tx/Rx) - highlighting efficiency without specialized high-gain arrays
-
Bandwidth: 20 MHz
-
Measured Upstream Speed: 15 Mbps (via UDP packet flooding)
Exceeding Critical Application Needs:
The achieved 15 Mbps stable upstream data rate significantly surpasses the 2-8 Mbps typically required for high-definition drone video transmission. This robust performance at the 150km benchmark distance, across such varied and challenging terrain (mountain peaks to sea level), proves the system's capability to handle:
-
Real-time HD/4K video feeds
-
Critical telemetry data
-
Command and control signals
...for drones operating at vast distances from their control stations.
Engineering Significance:
"This Longwang-to-Hangzhou Bay test wasn't about pushing the absolute maximum distance limit of our technology," stated a CroSkylink lead engineer. "It was about proving reliability and high throughput at the crucial 150km operational threshold under some of the toughest real-world conditions – a massive elevation drop using standard 5dBi antennas. Achieving a solid 15 Mbps uplink here demonstrates the core robustness and efficiency of our solution for missions where distance and terrain are major factors."
Broader Implications:
Successfully maintaining this level of performance over 150km across highly varied terrain unlocks potential for:
-
Large-Scale Infrastructure Monitoring: Inspecting remote pipelines, power grids (especially in mountainous regions), and offshore wind farms from a single ground station.
-
Expanded Emergency Response: Coordinating search & rescue or disaster assessment drones over vast, topographically complex areas (e.g., floods, wildfires, earthquakes).
-
Border & Coastal Security: Persistent, long-range surveillance without frequent relay points.
-
Precision Agriculture: Surveying thousands of hectares of varied terrain efficiently.
Positioning:
This successful test validates CroSkylink's technology as a solution capable of meeting the stringent real-world operational demands of beyond-line-of-sight (BLOS) drone operations at industry-leading ranges, particularly where challenging topography has previously limited reliable connectivity. It confirms the system's readiness to support critical long-distance drone applications today, with inherent headroom for future capabilities.
