Development of Mobile Communications
Mobile communications are currently in a new era of technological and industrial transformation. 5G communication will become an ultra-complex communication system that will significantly impact existing social ecosystems, reshape lifestyles, and lead humanity into an intelligent society. It represents a global information revolution following mechanization (steam engine), electrification (generator), and automation (computers).
Since 1980, global mobile communication technology has evolved roughly every decade.
1G (First Generation): Represented by North America’s AMPS (Advanced Mobile Phone System), it used analog cellular technology and supported only voice services.
2G: Represented by GSM (Global System for Mobile Communications), it adopted digital communication technology, enabling not only voice but also SMS services.
3G: Represented by technologies like WCDMA (Wideband Code Division Multiple Access), it introduced intelligent signal processing, supporting data and multimedia services.
4G: Represented by LTE (Long-Term Evolution), it utilized OFDM (Orthogonal Frequency Division Multiplexing) and MIMO (Multiple Input Multiple Output) technologies, enabling broadband data and mobile internet services.
5G: Driven by IoT (Internet of Things), AI, VR (Virtual Reality), 4K video, and other applications, as well as user demand, mobile data traffic is experiencing explosive growth. This will significantly increase the utilization of frequency resources, advance wireless transmission technologies, and make miniaturization, virtualization, and distribution of communication equipment the mainstream trends in future development.

Each generation of mobile communication technology has correspondingly raised new requirements for interconnection technologies and products. Future connectors will need to deliver faster transmission speeds, smaller sizes, higher density, greater intelligence, better environmental sustainability, and higher integration.
As a professional connector manufacturer with 50 years of experience, Aerospace Electric Appliances )began adapting its military-grade D-sub series connector technology for the communications/data communications field as early as 1995. Continuously expanding its product range, the company now offers comprehensive interconnect solutions for power, RF, high-speed signals, and optical transmission.
