The key characteristic of wireless networking is that it utilizes radio waves for data transmission. This technology allows devices to connect to a network without requiring physical cables. Wireless networking enables flexibility and mobility, as devices can communicate over the air, making it possible to move freely within the range of the signal while remaining connected to the network.

The use of radio waves is fundamental to how wireless communication works, as it allows for data to be sent and received over varying distances without being physically tethered through cables. This characteristic is what distinguishes wireless networks from wired connections, which rely on physical media for data transfer.

In terms of the other options, physical connections are not a feature of wireless networking, and latency can occur due to various factors in wireless connectivity, such as interference and distance from the access point. Additionally, wireless networks do not offer unlimited range; their effectiveness can be significantly impacted by obstacles like walls and interference from other electronic devices.
