From November 26th to 28th, the AIoT Korea Exhibition 2025, the only professional exhibition of smart IoT in Korea, will be grandly opened at Hall D, 3rd Floor, COEX Convention Center in Seoul . Hosted by the Ministry of Science and ICT of Korea and organized by the Intelligent IoT Association and K. Fairs, Ltd.
At the event, HOPERF, an upstream manufacturer of IoT wireless communication chips integrating "chip design, testing and development and manufacturing", will showcase its full range of Sub-GHz RF transceiver chips/modules, BLE chips/modules, Matter communication modules, LoRa communication modules and related solutions at booth F133. HOPERF will engage in extensive technical exchanges and resource sharing with IoT practitioners from around the world, jointly opening a new chapter in the smart IoT ecosystem.
The Korea AIoT International Exhibition is reportedly one of the world's leading IoT industry events, focusing on Internet of Things (IoT) and Artificial Intelligence (AI) technologies. It aims to provide a platform for IoT manufacturers, suppliers, industry professionals, and related organizations around the world to stimulate companies' thinking and insights into the IoT industry.
Sub-GHz RF transceiver chips/modules are a series of wireless transceiver products that only have basic RF transmission and reception capabilities. Terminal developers can design or program publicly available upper-layer protocol frameworks on this basis to accurately match various scenarios with personalized requirements for communication protocol architecture (such as private networks, private LPWAN (low power wide area network) or customized communication architectures).
In the communication modules of IoT devices, Sub-GHz radio frequency transceiver chips/modules with only physical layer (PHY layer) functions not only have a high degree of development freedom and can fully release the flexibility of protocol design to meet the technical needs of specific IoT applications, but also have a simpler hardware structure, making them an excellent solution for deploying large-scale IoT networks.
The HM-BT2401DA is a channel sounding module independently developed by Huapu Micro based on a high-performance BLE6.0 chip. It supports two ranging roles: initiator (which wants to calculate the distance from itself to the target device) and reflector (which responds to the initiator). It supports dual antenna paths and can quickly realize wireless connection and ranging between the initiator and reflector through AT commands. It has low external MCU resource consumption and simple development process.
The BLE6.0 channel detection solution primarily uses two proven ranging methods: phase-based ranging (PBR) and round-trip time (RTT) to enable secure and precise ranging between Bluetooth-connected devices. It can be widely used in fields such as indoor positioning, distance detection, digital keys, electronic fences, and proximity sensing .
LoRa wireless communication modules are standardized wireless communication products based on the Sub-GHz frequency band and using LoRa spread spectrum modulation technology. Their core advantage lies in the ability to freely design upper-layer protocol frameworks or directly program the LoRaWAN protocol stack. They are particularly suitable for large-scale IoT networking scenarios with clear requirements for communication stability, long-distance transmission, and low power consumption.
As one of the mainstream solutions in the IoT LPWAN field, LoRa wireless communication modules rely on the core advantages of LoRa spread spectrum technology and have three key characteristics: long transmission distance, low power consumption, and strong anti-interference capability. Through spread spectrum gain, a communication distance of several kilometers to more than ten kilometers can be achieved. It also supports a low-power working mode of sleep-wake-up and can effectively resist interference from other wireless signals in the same frequency band, ensuring the reliability of data transmission.
During the exhibition, HOPERF' senior technical engineer team will be stationed at booth F133 to provide professional one-on-one consultation services to every visitor, including:
· Technical Explanation: A detailed introduction to the working principles, performance characteristics, and competitive advantages of Huapu Micro's various product series .
· Application Case Sharing: Sharing successful application cases of Huapu Micro's various product series in different industries.
· We provide solutions: We offer professional technical advice and solutions tailored to your specific needs and the specific problems encountered in their implementation, and we jointly explore the possibilities and areas for cooperation in product customization.
