Frequently Asked Questions
Straight answers on the KF-DTU Gen1: wireless standard, range, mesh capacity, protocols, power, protection, setup, frequency confirmation, type-approval documents, RFQ quotation and samples.
What is the KF-DTU Gen1?
The KF-DTU Gen1 is an industrial wireless data transmission unit made by Jingfu Communication. It uses Wi-Fi HaLow (IEEE 802.11ah) Sub-1 GHz with a self-developed Mesh stack to connect RS485 and Ethernet field devices without cabling. Simiai Technology is the authorized export representative, based in Shenzhen, China. It is designed for civilian industrial IoT projects such as smart agriculture, energy monitoring, pipeline networks and smart metering.
What wireless standard and bandwidth does it use?
It uses Wi-Fi HaLow, the IEEE 802.11ah standard, in Sub-1 GHz spectrum. Bandwidth is selectable at 2, 4 or 8 Mbps, so the integrator can trade range and throughput for the site condition. Sub-1 GHz propagation gives the unit its field range and obstacle penetration, while the Mbps-class bandwidth supports dense Modbus polling and larger payloads than narrowband alternatives.
What range and mesh capacity does it offer?
Point-to-point range is up to 500 m, and a single hop can pass through 4 floors. The mesh relays across up to 10 hops with millisecond forwarding and supports star, chain, ring and mesh hybrid topologies. One network supports 50+ nodes and 500+ sensors, which covers most farm, plant and pipeline projects with a single local network design.
Which protocols and interfaces are supported?
The DTU supports TCP and UDP transport with Modbus RTU and Modbus TCP transparent transmission, so existing PLC, SCADA and monitoring software usually keeps its current polling logic. Wired interfaces are RS485 and RJ45 Ethernet. Each DTU can also carry up to 8 x 2.4G micro terminals for short-range expansion of nearby points.
What power supply does it need, and what is the transmit power?
Power is DC 4.7-16V wide voltage, which suits common field supplies and solar-plus-battery systems used at remote sites. Transmit power is up to 10 mW. The wide input range simplifies power design because the same unit can be used across cabinets, poles and field boxes with different local supplies, subject to your project power budget check.
Is it suitable for outdoor installation?
Yes, the housing is rated IP65, which is intended for outdoor field installation with protection against dust and water jets in normal industrial environments. Mounting position, cable entry sealing and local site practice still matter for long service life, so integrators should follow the deployment guidance and verify each node after installation.
How is it configured and managed?
Basic deployment is plug-and-play: connect the field device, apply power and the node joins the mesh. Management options are a Web interface for site setup, AT commands for module-level control, and CLI/JSON for scripted configuration or platform integration. That combination lets a field technician commission a simple site and an integrator automate a larger rollout.
How is the operating frequency handled for my market?
Operating frequency is configured for the destination market and confirmed in writing before quotation and shipment. Tell us the destination market in your RFQ so the frequency configuration can be confirmed for your project before any quotation is issued. Do not assume a single fixed frequency fits every market; the written confirmation is part of the RFQ process.
What type-approval documents are available?
Type-approval documentation and test support are available on request. Share your destination market and the documents your project or importer requires, and we will confirm what can be provided for your order during the RFQ process. Document needs differ by market, so they are confirmed per project rather than promised as a blanket claim on this site.
How do I get a quotation?
Commercial terms are handled by RFQ only, with no public price list on this site. Share your project quantity, destination port and requirements for a quotation, together with your device list, destination market and site distances. Contact Mr. Heming Wang at Simiai Technology by WhatsApp at +86 130 7787 8567 or by email at hemingwang@simiai.top or tim@simiai.top.
Can I get samples for a field test?
Samples are arranged via RFQ so the sample set matches your test plan. Tell us how many points you want to pilot, the topology you plan to test, the protocols involved and the destination market. We will confirm a sample configuration for a representative field test - for example one cluster or one chain segment - before you commit to a project quantity.
Who is the KF-DTU Gen1 for, and how do I contact you?
It is for system integrators, industrial automation distributors, IoT solution providers, smart-meter makers, solar and wind EPCs, pipeline monitoring contractors and agri-tech companies working on civilian industrial IoT projects.
