WiFi, or wireless fidelity, may be the most physically—yet virtually—ubiquitous technology we use to experience music. Today, with streaming services, one can listen to music without even downloading it to one’s phone, as long as one has a WiFi connection and an app for that. Spotify is the most prevalent of the streaming services in 2018, but it follows many sites like Pandora, which mimics the radio, and SoundCloud and bandcamp, which are largely populated with independent artists releasing their own music.
WiFi uses radio waves to connect networks. This connection is established once it detects a wireless adaptor. These adaptors then may create hotspots, where WiFi can be detected by any device that can connect to these networks, such as a cell phone or an iPad. The vicinity of these hotspots varies according to the strength of the radio signal, and allows the user to access the Internet. Today, WiFi can exist almost anywhere, particularly in densely populated areas, but it does require some kind of subscription. In the home, one must pay to access WiFi on a monthly basis, which may limit one’s access to the Internet in a socially or professionally debilitating way. For a computer to utilize WiFi, radio waves must be sent between a wireless adaptor a wired Ethernet cable. The signal is then transmitted via antenna to the wireless router, and data is sent through the Ethernet cable to one’s computer device, whether it be a phone, tablet, or laptop—or any myriad technology that is holistically connected with the rest of the world through the Internet.
