Title: The Development of Modern Communication Technology
Article: In recent years, the development of wired and wireless communication technology has been advancing rapidly. Wired communication services play a crucial role in home and enterprise networks, providing telephone lines and broadband internet connections. On the other hand, wireless communication utilizes wireless radio waves, frequencies, and wireless technology to achieve mobile communication and satellite communication. Wireless devices in communication systems include base stations, cellular networks, and wireless access points, using radio frequency technology for wireless transmission and connection. The improvement of wireless transmission rates and the application of wireless expansion technology have led to the continuous upgrading and development of wireless networks such as 2G, 3G, 4G, and 5G. Internet access service providers (IASPs) play a vital role in this system, providing efficient communication services to users.
