Through which of the devices listed can we connect to wireless networks?

The choice of radio as the device that can connect to wireless networks is rooted in the technology and principles behind wireless communication. Radios operate using electromagnetic waves to transmit and receive information, making them inherently suitable for connecting to various types of wireless networks, including Wi-Fi and cellular networks.

While smart TVs often have Wi-Fi capabilities to connect to the internet or streaming services, they are generally considered consumer electronics that rely on other devices and infrastructure rather than functioning independently as a means of connecting to wireless networks. Similarly, antennas serve as components that can receive or transmit signals but do not directly connect to networks in the manner that allows for data exchange without additional hardware. Telephones, particularly traditional landline models, are typically reliant on wired connections for service, although smartphones can access wireless networks through cellular and Wi-Fi connections.

The fundamental characteristic of radio technology—its ability to utilize radio waves for wireless communication—makes it the most appropriate choice in the context of connecting to wireless networks.
