K-Best eyeing opportunities in global IoT market

K-Best Technology, a subsidiary of Acer, is gearing up efforts to introduce its wireless communication technology to the world, as it sets sights on business opportunities in the global Internet of Things (IoT) market.

Having attracted investment from Acer about 20 years ago, K-Best built the Super Taiwan Radio (Super TaiRa) wireless communication technology using radar software technology developed by the National Chungshan Institute of Science and Technology (NCSIST) and LoRa chips from Semtech in 2018.

Two years later, the company unveiled its advanced wireless global radio (GloRa) technology for industrial and business applications.

K-Best president YW Tung said the company's Super TaiRa and GloRa technologies have been adopted by the likes of Formosa Plastics Group, AU Optronics (AUO), and Wistron in Taiwan. He said the company now wants to expand its presence in the global market through strategic development of IC and communication modules.

Featuring long communication distance, high anti-interference capability, and a data transmission rate of 50-500 bytes/s, LoRa networking technology has been widely deployed for IoT applications, said Tung. However, the technology is subject to a high packet error rate in wireless environments and poor signal processing quality under one-to-many and many-to-many architectures, he explained.

To address the shortcomings of LoRa networks, K-Best has developed new LoRa technologies Super TaiRa and GloRa using special software and firmware, Tung said, adding that Super TaiRa is designed for military use while GloRa is not.

Compared to traditional LoRa technologies, which only has a throughput of 20-30%, GloRa and Super TaiRa can achieve a throughput of 70-80% and 85-99%, respectively, according to Tung. He noted that the main obstacle preventing GloRa and Super TaiRa from becoming more popular is their relatively high selling price. However, the company is planning to adjust their solutions to meet non-professional demand in the future.
