What is Wi-Fi?
Wi-Fi is the technology that uses radio waves to provide network connections between computers and the internet and between devices on the same network, like between your computer and a wireless printer in your home. Wi-Fi has one significant benefit – freedom! Wi-Fi connects devices without cumbersome wiring.
Hotspots are locations where you can access the internet using a Wi-Fi signal. You’ll find hotspots in cafes, airports, the library, and other public areas. Almost 45% of people who have used a public hotspot say they’re more likely to patronize a business that offers Wi-Fi. 61% of home Wi-Fi users say they are more productive since they’ve started using Wi-Fi.
To understand how Wi-Fi works, think about a cordless telephone. The base unit and the phone send wireless radio signals back and forth, allowing you to talk on the phone without a handset wired to the base.
Wi-Fi works much the same way. A wireless router connects devices wirelessly to the internet. Wi-Fi is a low-power radio signal that typically only reaches about 150 feet indoors, depending on the obstructions, like walls and furniture, blocking the signal. There are options for increasing the reach using mesh systems or extenders (repeaters). For more information on how to set up Wi-Fi in your home, take our Going Wireless course.
