This has prompted numerous prominent mobile service providers to view 5G-based FWA as a new growth driver, in contrast to saturation in the mobile phone market, leading to substantial anticipated subscriber expansion.

Business Development Overview

The Fourth Industrial Revolution is rapidly unfolding worldwide, driven by the increasing adoption of key enabling communication technologies such as 4.5G, 4.75G, and 5G wireless networks. This growth has led to the emergence of a high-speed wireless internet-based 4.5G/4.75G/5G wireless broadband market and related wireless devices and chipsets. We specialize in providing baseband modems, RF chipsets, and protocol software that enable stable communication on 4.5G/4.75G/5G wireless carrier networks. Wireless modems consist of both hardware components, such as RF transceivers and baseband modems, and software responsible for modem operation, protocol processing and system operation. These elements must work together seamlessly to deliver optimal performance and solutions, making this a critical technology for the Fourth Industrial Revolution. However, there are very few companies globally that can commercialize these technologies, given their high complexity and technological barriers. We have continuously focused on wireless communication product development since our establishment, and believe our core technologies and compatibility testing capabilities acquired during the development and sale of our competitive wireless communication chipsets are unique and not easily duplicated by new entrants in the market. Thus, we have secured a strong competitive position by providing competitive and optimized solutions in the mobile communication market where different generations of technology coexist.

We possess essential core technologies for enhancing the wireless data communication capabilities of competitive 4G/4.5G/4.75G/5G chipsets. We commercialized wireless communication chipset technology using four or eight multiple antennas to achieve outstanding performance improvements in speed, coverage expansion, and interference reduction, earning recognition from top global carriers. We introduced the 4x4 MIMO 4.5G chipset technology with four antennas in Japan, followed by commercialization of eight-antenna products in the United States and Europe. RF/modem chipset technology using multiple antennas is particularly vital for FWA services that require stable data communication without interruptions in fixed locations. In countries and regions where it is challenging to install high-speed wired networks, such as optical fiber, due to geographical, technical and economic reasons, wireless broadband FWA using 4G and 5G is an increasingly cost-efficient alternative. This service is rapidly expanding worldwide as a core component of the Fourth Industrial
