Wireless networking is a method by which homes, telecommunications networks, and business installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. The main purpose of using a wireless network is its flexibility, roaming, low cost, and high standard.
Types of Wireless Networks.
You are viewing: Which Of The Following Is Not True About Wi-fi Networks
- WLAN (Wireless Local Area Network)
- WWAN (Wireless Wide Area Network)
- WMAN (Wireless Metropolitan Area Network)
- WPAN (Wireless Personal Area Network)
- Ad-hoc Network.
- Hybrid Network.
Wi-Fi is a wireless networking technology that allows devices such as computers (laptops and desktops), mobile devices (smartphones and wearables), and other equipment (printers and video cameras) to interface with the Internet. Internet connectivity occurs through a wireless router.
- In general, wireless networks are less secure than wired networks since the communication signals are transmitted through the air. Because the connection travels via radio wave, it can easily be intercepted if the proper encryption technologies (WEP, WPA2) are not in place.
- Wired networks are generally much faster than wireless networks. This is mainly because a separate cable is used to connect each device to the network with each cable transmitting data at the same speed. A wired network is also faster since it never is weighed down by unexpected or unnecessary traffic.
- Wireless networks enable multiple devices to use the same internet connection remotely, as well as share files and other resources. There are also disadvantages to wireless networks, however, especially when you compare them with wired networks, which generally maintain a faster internet speed and are more secure.

Benefits of Wireless Network
- Increased Mobility: Wireless networks allow mobile users to access real-time information so they can roam around your company’s space without getting disconnected from the network. This increases teamwork and productivity company-wide that is not possible with traditional networks.
- Installation Speed and Simplicity: Installing a wireless network system reduces cables, which are cumbersome to set up and can impose a safety risk, should employees trip on them. It can also be installed quickly and easily when compared to a traditional network.
- Wider Reach of the Network: The wireless network can be extended to places in your organization that are not accessible for wires and cables.
- More Flexibility: Should your network change in the future, you can easily update the wireless network to meet new configurations.
- Reduced Cost of Ownership over Time: Wireless networking may carry a slightly higher initial investment, but the overall expenses over time are lower. It also may have a longer lifecycle than a traditionally connected network.
- Increased Scalability: Wireless systems can be specifically configured to meet the needs of specific applications. These can be easily changed and scaled depending on your organization’s needs.
Therefore Option 2 is the correct answer.
