What is the main characteristic of a Wireless Network?

It relies solely on fiber optic cables
It is connected via physical cables
It utilizes 802.11 standards
It has a fixed bandwidth allocation

The correct answer is: It utilizes 802.11 standards

The main characteristic of a wireless network is that it utilizes 802.11 standards. This designation refers to a set of protocols developed for implementing wireless local area networks (WLANs) in various settings, including homes and businesses. The 802.11 family encompasses a range of protocols that facilitate wireless communication, allowing devices to connect without the need for physical cables. This characteristic is crucial because it defines how data is transmitted through the air using radio waves, enabling mobility and flexibility for devices within the network. In contrast, relying solely on fiber optic cables and being connected via physical cables refer to wired networking, which fundamentally differs from the principles of a wireless network. Additionally, the concept of fixed bandwidth allocation typically pertains to wired networks where bandwidth can be managed and controlled more easily compared to the dynamic nature of wireless communication.
