Learn SpecificationsShenzhen Huaxiasheng Technology Co., Ltd. has been at the forefront of wireless data transmission product development, system application design, and complex network engineering since 1996. For nearly three decades, we have engineered world-leading wireless communication solutions tailored to the strict demands of diverse industrial verticals.
By leveraging robust collaborations with China's top aerospace, telecommunication research institutes, and elite universities, we develop high-reliability proprietary RF links. Our solutions address the exact environmental challenges of major global shipping hubs, including the high-humidity, high-interference coastal conditions of the Chittagong market.
Providing high-gain, interference-resistant data links for the commercial engine of Bangladesh.
Handling over 90% of Bangladesh’s import-export trade requires massive automation. Our high-bandwidth COFDM IP MESH radios power Real-Time Kinematic (RTK) positioning for automated container cranes (RTGs), CCTV security on tugboats, and terminal operating system (TOS) data links where traditional Wi-Fi fails.
In the Chittagong Export Processing Zone (CEPZ) and Karnaphuli EPZ, steel fabrication mills, petrochemical refineries, and cement plants utilize our long-range digital data radios for SCADA. Operating on licensed VHF/UHF bands, they ensure telemetry transmission through thick concrete structures and dense metal environments.
Navigating the complex channel of the Karnaphuli River requires constant bathymetric surveying. Our GNSS/RTK wireless data links offer sub-decimeter positioning correction over 20km, enabling continuous hydrographic surveying and vessel tracking systems in the Bay of Bengal.
The Chittagong maritime corridor presents severe challenges for wireless links: high relative humidity (often exceeding 85%), salt spray corrosion, intense monsoon rains, and massive dynamic structural obstructions from container stacks and vessels. Standard off-the-shelf industrial routers suffer from rapid path loss, signal dispersion, and fast multipath fading.
Huaxiasheng Technology solves this by employing Frequency Hopping Spread Spectrum (FHSS), MIMO Multi-antenna technology, and COFDM (Coded Orthogonal Frequency Division Multiplexing). Our systems provide a high fade margin (exceeding 25dB) ensuring that telemetry, HD video, and control signals remain uninterrupted even during dense coastal monsoons.

As a vertically integrated wireless equipment manufacturer based in Shenzhen, China's Silicon Valley, Shenzhen Huaxiasheng Technology Co., Ltd. delivers distinct supply chain advantages to our clients in Bangladesh:
The industrial wireless sector is shifting rapidly from legacy low-speed serial connections to dynamic IP networks. Our technical roadmap ensures your infrastructure investment in Chittagong is future-proof:
We are integrating multi-band MESH systems that automatically switch frequencies when encountering local interference. In addition, our next-generation software-defined radios (SDR) support over-the-air firmware updates, allowing field units to adapt to new modulation techniques and local spectrum re-allocations without physical replacement.
Whether you are implementing unmanned surface vessels (USVs) for port security, automated guided vehicles (AGVs) in terminal yards, or distributed smart-grid sensors across the Chittagong division, our hardware supports open standards (TCP/IP, Modbus TCP, RTSP) for easy integration.
Delivering on the core values that make us a global leader in critical communication links.
Shenzhen Huaxiasheng Technology Co., Ltd. is a top-tier communication equipment designer in the MESH self-organizing network industry. We deliver rich product variety, long-range capabilities, high transmission speeds, and exceptional anti-interference performance.
Beyond our physical hardware, we provide extensive pre-sales path analysis, link budget calculations, and post-sales integration guidance. We ensure your local engineers in Chittagong can deploy and maintain every link safely and reliably.
We are committed to providing premium, robust hardware at reasonable prices. Driving innovation forward while providing reliable, industry-proven wireless links for automated systems is our core long-term objective.
At present, Huaxiasheng develops and produces a wide range of advanced communication systems including digital data transmission radios, intelligent data transmission transceivers, high-speed frequency hopping modules, industrial wireless Ethernet bridges, network high-definition image transmission modules, AD-HOC/MESH self-organizing networks, GNSS/RTK wireless data links, industrial wireless remote I/O, handheld mobile data voice transceivers, two-way RF power amplifiers, and voice codecs.
These systems are widely utilized across global industries including oil and gas pipeline monitoring, water and wastewater telemetry, smart electrical grids, municipal heating/gas networks, railway signal control, urban street lighting, seismic/meteorological observation, environmental telemetry, GPS survey mapping, chemical process automation, long-range maritime video links, and multi-channel telemetry for UAVs, unmanned surface vessels (USVs), and robotics.
Deploying industrial wireless networks in Chittagong requires careful consideration of local spectrum regulations set by the Bangladesh Telecommunication Regulatory Commission (BTRC). Frequencies must be chosen to avoid local interference while optimizing path propagation over coastal terrain.
For license-free applications, our 2.4GHz and 5.8GHz broadband MESH devices are ideal. For long-distance SCADA applications, we offer VHF (136-174MHz) and UHF (400-470MHz) radios. These frequencies provide superior penetration through maritime obstacles and can be formally licensed through BTRC. Our engineering team assists local partners with path loss profiles (using Longley-Rice models) to ensure reliable line-of-sight (LOS) and non-line-of-sight (NLOS) performance before purchasing.

All our industrial-grade outdoor radios and modules feature optional IP67/IP68 enclosures with anti-corrosion marine-grade coatings. The internal PCBs are treated with thick conformal coating to protect active circuits from oxidation and humidity-induced tracking failures typical in maritime hubs like Chittagong.
For short-range, high-bandwidth applications (such as automated container terminals), 2.4GHz or 5.8GHz MESH networks are ideal. For long-range telemetry and RTK base station corrections across the Karnaphuli river, we recommend UHF (400-470MHz) or 900MHz bands which provide superior diffraction around cranes and vessels.
Yes. Because we control the entire R&D and manufacturing process in our Shenzhen factory, we can customize the hardware filters and firmware parameters of our radios to operate precisely within the specific frequency bands allocated to your organization by the BTRC.
In heavy industrial zones with significant metal infrastructure (NLOS conditions), typical range for our low-frequency high-power data radios is 3km to 8km. In line-of-sight (LOS) conditions, such as ship-to-shore links, our devices easily exceed 30km to 50km with appropriate high-gain directional antennas.
Yes, our digital data radios and industrial routers natively support standard protocols including Modbus RTU, Modbus TCP, Profinet, and transparent serial data transmission over RS232/RS485/Ethernet interfaces, making them fully compatible with PLC and SCADA equipment.
