Final answer:
Wi-Fi is another name for a wireless network, with the term often mistakenly thought to mean 'wireless fidelity'. It enables devices like cell phones and laptop computers to connect to the Internet through a wireless WiFi router using the 2.4 GHz to 5.0 GHz frequency range.
Step-by-step explanation:
The other name for a wireless network is Wi-Fi. The abbreviated name for the Wi-Fi Alliance is also Wi-Fi, which sometimes people think stands for 'wireless fidelity' although it is actually just a trademarked term. Wi-Fi technology uses microwaves in the frequency range of 2.4 GHz to 5.0 GHz to provide wireless communication between devices like routers, cell phones, and computers. Unlike Bluetooth, which also operates in the 2.4-GHz range for nearby device connections, such as headphones to smartphones, Wi-Fi allows these devices to connect to the Internet wirelessly. This connectivity is provided through a wireless WiFi router, which exchanges data over the internet via a cable or other connection and communicates wirelessly with devices using microwave signals according to established Wi-Fi standards.
