Explore our core industrial-grade wireless modules, designed for long-range SCADA, MESH networks, and high-precision GNSS/RTK applications.
Shenzhen Huaxiasheng Technology Co., Ltd. has been at the forefront of wireless data transmission product development, application, and network engineering for nearly three decades. Since our inception in 1996, we have independently developed cutting-edge wireless equipment tailored to the rigorous demands of global industrial automation, geodetic surveying, and high-precision positioning.
By leveraging deep collaborations with top-tier domestic universities and research institutes, we continuously inject information gain into our product designs. Our solutions integrate advanced RF engineering with robust digital signal processing to deliver unmatched reliability in complex electromagnetic environments.
Understanding the critical role of robust UHF and MESH telemetry in centimeter-level RTK positioning and geodetic surveying.
Real-Time Kinematic (RTK) positioning demands zero-latency transmission of RTCM 3.x differential correction data. Our data links utilize optimized GMSK/4FSK modulation to ensure uninterrupted data streams, enabling centimeter-level accuracy for GNSS receivers.
Operating in crowded unlicensed bands (such as 902-928MHz or 410-470MHz) requires superior anti-interference. Our proprietary high-speed frequency-hopping algorithms dynamically bypass congested channels, maintaining robust connections even in heavy RF environments.
To ensure seamless integration with legacy surveying equipment, our wireless data links natively support industry-standard protocols including Trimtalk 450S, Satel, Pacific Crest, and transparent transmission modes, eliminating integration friction.
Unlike standard SCADA telemetry, GNSS RTK corrections require continuous, low-latency, and jitter-free transmission. A packet loss of even 5% can cause an RTK receiver to lose its "Fix" status, reverting to "Float" and degrading accuracy from centimeters to decimeters. Huaxiasheng's custom GNSS data links implement Forward Error Correction (FEC) combined with a highly optimized RF front-end, achieving a packet delivery rate exceeding 99.9% at distances up to 20 kilometers.
Sourcing your GNSS wireless data links from Shenzhen Huaxiasheng Technology Co., Ltd. unlocks unparalleled supply chain advantages. Located in the heart of the world's electronics manufacturing hub, our state-of-the-art facility features fully automated SMT lines, advanced RF testing chambers, and strict quality control protocols.
Our vertical integration allows us to manage everything from PCB design and firmware optimization to CNC enclosure fabrication. This drastically reduces lead times for custom OEM/ODM requests and guarantees consistent component sourcing, shielding our global clients from supply chain disruptions.
Every single module undergoes rigorous environmental stress screening (ESS), including thermal cycling and vibration testing, ensuring they withstand the harshest field conditions in agriculture, marine, and mining operations.
How we tailor our wireless telemetry solutions to meet the strict technical and regulatory demands of international buyers.
Navigating global radio regulations can be daunting. We design and manufacture modules that comply with FCC (North America), CE RED (Europe), SRRC (China), and MIC (Japan) standards. We assist our clients throughout the entire certification process for custom designs.
Every project has unique constraints. Whether you require a specific form factor, custom frequency bands (e.g., 868MHz, 915MHz, or 2.4GHz), specialized interfaces (RS232, RS485, TTL, Ethernet), or high-power RF output (up to 35W), our engineering team delivers.
We don't just sell hardware; we provide complete communication solutions. From pre-sales link budget calculations and antenna selection to post-sales network deployment and troubleshooting, our dedicated team of field engineers is always ready to assist.
How emerging technologies are shaping the next generation of high-precision wireless data links.
The high-precision positioning landscape is undergoing a massive paradigm shift. As industries transition from traditional RTK to PPP (Precise Point Positioning) and hybrid RTK-MESH networks, the demands on wireless data links have skyrocketed. Modern systems must handle not only standard RTCM corrections but also high-bandwidth diagnostic data, video streams, and command-and-control signals.
At Huaxiasheng, we are actively integrating MIMO (Multiple-Input Multiple-Output) technology and COFDM (Coded Orthogonal Frequency Division Multiplexing) into our wireless links. This allows for simultaneous high-speed data and HD video transmission over ultra-long distances, even in highly obstructed Non-Line-of-Sight (NLOS) environments.
Furthermore, the integration of AI-driven cognitive radio technology enables our modules to intelligently sense the spectrum, automatically shifting to clean frequencies to prevent interference before it impacts positioning accuracy.
From autonomous tractors to deep-sea surveying, our custom data links deliver rock-solid performance.
Our GNSS data links are integrated into autonomous steering systems and smart implements, ensuring centimeter-level accuracy for planting, spraying, and harvesting, maximizing crop yields and reducing input costs.
Surveyors worldwide rely on our high-power base station radios and compact rover modules to maintain stable RTK links in dense forests, urban canyons, and mountainous terrain.
With ultra-lightweight designs and low power consumption, our OEM modules are ideal for drones, unmanned ground vehicles (UGVs), and marine robots requiring long-range telemetry and precise positioning.
