About Us

Professional Wireless Communication Devices Manufacturer

Who We Are: We are a manufacturer specializing in wireless communication devices, with our own R&D, production, and quality control teams. Our core product lines cover wireless bridge devices (point-to-point and point-to-multipoint transmission), mesh networking devices, Wi-Fi modules, and mesh roaming client devices. We build on mainstream platforms such as Qualcomm, covering 1.4G/2.4G/5G/6G multi-band operation and Wi-Fi 5/6/7, ship devices powered by our self-developed proprietary system, and provide OpenWrt-based secondary development — delivering complete, ready-to-deploy devices rather than just boards.

Custom Wireless Device Solutions (OEM/ODM): Every product we ship — from industrial-grade wireless bridges and mesh self-organizing network devices to Wi-Fi modules and mesh roaming clients — is designed, manufactured, and tested in-house for high-reliability scenarios such as high-power NLOS transmission, industrial roaming, vehicle/AGV systems, emergency response, video surveillance backhaul, and IoT gateways. We support full OEM/ODM customization with complete transparency, so overseas customers always know exactly where things stand. Here's what our typical OEM timeline looks like, built around the things that matter most: speed, compliance, and control:

1. Requirements Definition & Solution Alignment (1–3 business days)
Our English-speaking engineering team works with you to define device specifications, transmission distance and bandwidth targets, roaming performance requirements, mechanical and mounting details, compliance needs (CE, FCC, RoHS, etc.), and order volume. We then deliver a detailed solution proposal and quote so everyone's on the same page from day one.
2. Sample Engineering & Validation (5–7 business days)
We rapidly complete hardware design, firmware development, and prototype builds, and deliver full test reports covering throughput, roaming handover, stability, and environmental reliability. We'll go through as many revision cycles as it takes until the samples match your requirements and get signed off.
3. Pre-Production Preparation & Pilot Run (3–5 business days)
Once samples are approved, we source materials through our stable global supply chain (genuine components, on schedule), set up the production line, and finalize assembly and testing procedures. A pilot run of up to 500 units confirms process stability and device-to-device consistency before we ramp up.
4. Volume Production (7–20 business days, depending on order size)
After the pilot run passes qualification, we kick off full-scale production under ISO quality management. Every device is individually tested — RF performance, roaming behavior, and aging tests included — by dedicated QC staff. We send daily production and test reports so you always have real-time visibility into progress and quality.
5. Final Inspection & Shipment (1–2 business days)
Once production wraps up, we perform 100% final inspection and reliability testing, issue certified test reports, and ship through our global logistics network. All customs documents — commercial invoices, packing lists, test certificates — are included to make international delivery as smooth as possible.

We make the jump from prototype to full production as seamless as possible, with English-language support at every stage so your OEM project runs efficiently and without headaches.

Comprehensive After-Sales Support: We know that good after-sales support is what makes or breaks an international partnership. That's why we offer fast, professional, fully traceable post-sale service designed to give you real peace of mind: a 24/7 English tech support hotline and online chat for quick help with device configuration, troubleshooting, and firmware guidance; a solid warranty covering free repair, part replacement, or rework for non-human-induced defects; a traceability system with unique serial numbers on every device so issues can be located and resolved fast; firmware upgrade and OTA support to keep deployed devices up to date; on-site support and commissioning available for bulk orders (depending on your region); and long-term spare parts availability so your maintenance and upgrade needs are covered well into the future.

Global Reach & Partnership Commitment: Our wireless bridges, mesh devices, Wi-Fi modules, and mesh roaming clients are deployed in industrial automation, security and surveillance transmission, smart home, IoT, emergency communications, renewable energy, vehicle-mounted systems, and more. With a solid supply chain and global shipping network, we deliver on time, keep costs in check, and back everything with reliable support. We're here to be your go-to partner for professional wireless communication devices — plain and simple.
