LG Innotek claims smallest BLE module for IoT

By Gina Roos, editor-in-chief

LG Innotek has claimed the industry’s smallest Bluetooth Low Energy (BLE) module, measuring 6 mm (width) x 4 mm (height), which is 75% of the previous model. Thanks to ultra-precision, high-density, and ultra-fine processing technologies, the communication module for IoT devices packs more than 20 components including communications chips, resistors, and inductors, in a grain-sized package.

The smaller size combined with improved communication performance opens up design opportunities for new and smaller form factors. The module is well suited for IoT devices that require limited power supply, such as small wearable devices, thanks to its low power consumption. Applications include glucose measuring patches, smart lighting, outlets, switches, wireless earphones, and hearing aids.

Despite its small size, the BLE module provides excellent communication performance thanks to the differentiated radio frequency (RF) signal design and antenna technology, as well as its ultra-precision circuit technology. These combined technologies help reduce component space, eliminating signal interference while increasing the data transmission distance.

LG said the communication performance of the module is improved by 30% compared to existing products, enabling data transmission even if there are obstacles such as a wall between the user’s smartphone and IoT device.

The increased transmission was achieved by using  the company’s proprietary “integrated antenna” technology. In conventional designs, the antenna is installed separately outside the module. With the proprietary technology, the antenna is mounted inside the module. It was designed to cover the entire module to maximize the antenna area for improved performance.

The company will continue to develop IoT communication modules for the global market, including 5G modules for vehicles and Wi-Fi/Bluetooth modules for home appliances.
