Wi-Fi allows electronic devices to connect to the internet and each other wirelessly using radio bands. Devices like computers, phones, and tablets can access the internet through a wireless network access point with a typical range of 20 meters indoors. Now Wi-Fi is ubiquitous and we rely on constant internet access through our smartphones, laptops, and other mobile devices for tasks like staying in touch, banking, getting information, and planning activities. Without internet access, common activities would be more difficult and time consuming.
