The industry predicts that the number of IoT-connected devices in the world is expected to reach 30.9 billion in 2025, and the number of IoT-connected devices in China will double to 8 billion in 2020, showing an explosive growth trend. The wireless communication module is an indispensable bridge to connect the Internet of Things. Every time the number of wireless Internet of Things connections is increased, at least one wireless module is added. Therefore, the wireless communication module is irreplaceable as the hardware foundation for the connection of all things. It is a high-certainty benefit. The industrial link where the number of connections exploded.
Huge market opportunities have attracted major players from all over the world to enter the game. Kaga FEI Electronics Co., Ltd. (KAGA FEI, referred to as Kaga FEI Electronics), which is committed to providing high-performance IoT products and services, is one of them. Acquired the commercial rights, development and manufacturing technologies and intellectual property rights of Bluetooth and wireless LAN modules from TAIYO YUDEN Co., Ltd. in 2009, officially launched the small wireless module business, and established the IoT solution brand – CONTINECT , dedicated to the Wireless Solutions business. “Kaga Fuyi Electronics, with ‘wireless technology’ as the core, proposes a full-chain wireless solution based on technology and experience, including LSI, contract design and manufacturing services, network and cloud computing, and strives to develop small wireless module business for those in communication equipment. and global customers engaged in the development of IoT products in the field of consumer electronics to provide the most promising products,” said Du Fudan, Marketing Director of Product Management Department of Kaga Fuyi Electronics (Shanghai) Co., Ltd.

On the road of “involution” of wireless module performance, CONTINECT rolls out a new dimension of cost performance
The form of WLAN+Bluetooth dual-mode chip is gradually becoming the mainstream of the wireless connection of the Internet of Things, which optimizes the network distribution experience of terminal products, and the dual-mode module greatly simplifies the difficulty of product network distribution. Connecting to the mobile phone through Bluetooth guides users to quickly add devices. Do “dumb level” application. On the other hand, it also optimizes the stability of the distribution network. Smart devices equipped with WLAN+BLE dual-mode modules can greatly solve the distribution network problems in the 2.4G & 5G dual-band/mixed-frequency routing environment, with higher compatibility. “In practical applications, the small size, low power consumption and high cost performance of wireless modules are the keys to being popular with manufacturers, and this is also the key to Kaga’s differentiation among many suppliers.” Du Fudan said.
The wireless modules provided by CONTINECT are mainly Bluetooth and wireless LAN. In addition to inheriting the development of products and business models from PAN, LAN series and communication series by Taiyo Yuden according to the needs of multi-level customers, CONTINECT will continue to provide products from the wireless field. , modules, software support to various certification services, etc., to provide customers with the overall solution needed when developing and selling wireless products.
CONTINECT’s strengths are not only high-density, high-reliability small-volume module products, but also the materials and manufacturing process technology accumulated during the long-term production of capacitors, inductors and other products by Taiyo Yuden to equipment, module production, and certification services Among them, it is also the advantage of CONTINECT. “Taiyo Yuden is a global leader in passive components. Whether it is capacitors, inductors, or antennas, it is a very competitive technology field. These have played a key role in CONTINECT wireless modules. Therefore, CONTINECT wireless modules are in small It has industry-leading competitive advantages in terms of size, low power consumption and stability.” Du Fudan emphasized.
IoT-related devices such as wearables are very small and therefore use small batteries, so most of these devices use Bluetooth technology. CONTINECT’s ultra-compact wireless modules can measure as small as 3.25mm x 8.55 mm, the world’s smallest size class, and also have a built-in antenna and master clock, so they can operate wirelessly without the need for wireless peripherals. CONTINECT’s ultra-compact wireless modules are lighter than metal-shielded products, and the entire module weighs less than 0.1 g, ideal for installation in similar electric toothbrushes and wearables.

Besides size, low power consumption is also one of the key requirements for wireless communication modules in IoT devices. Although the communication speed of Bluetooth low energy communication standard (BLE for short) is not as fast as that of Wi-Fi communication, and it is not suitable for large-capacity communication such as image and video data, it is still suitable for data communication such as sensor data with relatively small communication volume. It is an ideal choice. For example, the wireless modules that generally appear in mobile POS machines refer to BLE low-power Bluetooth modules. CONTINECT has more than 20 BLE modules, as well as a series of wireless communication products equipped with both Wi-Fi and BLE modules and using different communication standards, all of which can achieve the lowest power consumption for short-range communication, which will greatly extend the life of IoT devices. Working hours, ideal for mobile POS machines, connected devices in smart homes, etc.
From wireless testing and certification to EMS manufacturing, create a new model of wireless module product service differentiation
As the name suggests, the wireless connection performance of the wireless module is fundamental. “However, the main board, housing resin, metal, etc., which are usually installed around the antenna of the wireless module, affect the radio waves, thereby affecting the communication distance of the product. In addition, if the shape of the product is given priority, the wireless module may not necessarily be installed under ideal conditions, Therefore, there must be an antenna measurement support, and the antenna measurement service provided by CONTINECT can confirm the state contained in the product or the radiation pattern in the prototype.” Du Fudan pointed out.
As mentioned above, the radio wave characteristics of the wireless module are affected by the board and casing around the module. If there is a requirement, the general designer will consider the installation of the wireless module at the stage of product appearance shape and placement. “Usually, in the equipment design stage, CONTINECT will let the technical team work with the customer to determine the installation location, orientation and the design of the product housing shape based on some information provided by the customer, such as the design of the circuit board to be installed and the surrounding environment of the product, In order to maximize the wireless characteristics according to customer requirements.” Du Fudan said. “Most radios have markings (technical suitability markings) for specific radio equipment, such as ‘Technical Standard Compliance Certification / Structural Design Certification’, which certify that specific radio equipment (such as those used for small radios) complies with The technical standards of radio wave laws and regulations. By obtaining these certifications, customers will be able to put the technical suitability mark on their products for the first time.” Du Fudan pointed out. It is reported that Kaga Fuyi Electronics’ wireless modules not only support the acquisition of “technical standard compliance certification” (commonly known as “technical compliance”) and “structural design certification” in Japan, but also obtain overseas radio law certification, which can help customers Accelerate the mass production and launch of products. “
The explosive growth of IoT applications has provided a rapid development track for various companies around the world. However, how to focus on their areas of expertise and quickly launch their own products to target customers often becomes a bottleneck in the asset-heavy manufacturing process.
