\"Radio waves\" transmit music, conversations, pictures and data invisibly through the air, often over millions of miles -- it happens every day in thousands of different ways! Even though radio waves are invisible and completely undetectable to humans, they have totally changed society. Whether we are talking about a cell phone, a baby monitor, a ...
The list goes on and on... Even things like radar and microwave ovens depend on radio waves. Things like communication and navigation satellites would be impossible without radio waves, as would modern aviation -- an airplane depends on a dozen different radio systems. The current trend toward wireless Internet access uses radio as well, and that m...
The funny thing is that, at its core, radio is an incredibly simple technology. With just a couple of electronic components that cost at most a dollar or two, you can build simple radio transmitters and receivers. The story of how something so simple has become a bedrock technology of the modern world is fascinating!
Mar 27, 2001 · It is a continuous broadcast that works through three software packages: the encoder, the server and the player. The encoder converts audio content into a streaming format, the server makes it available over the Internet and the player retrieves the content. For a live broadcast, the encoder and streamer work together in real-time.
May 24, 2022 · How Wi-Fi fits in. Wi-Fi uses radio waves with a faster frequency than AM and FM radio. While AM radio is measured in kilohertz and FM radio in megahertz, Wi-Fi is measured in gigahertz. This measurement is why you see Wi-Fi connections labeled as 2.4 GHz and 5 GHz—which are a generalization of frequency ranges.

Thanks to Wi-Fi, we no longer have to be tethered to the Internet with cables. But have you ever stopped to wonder how it works? Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz.
Dec 30, 2021 · Artwork: Tethering: Your laptop connects to your cellphone over Wi-Fi (red). Your phone connects to a 3G, 4G, or 5G cellphone network (blue). That network hooks into the public telephone network and the Internet's mail, web, and other servers using a mixture of fiber-optic and wired connections (orange).

Jun 18, 2020 · Wi-Fi is a brand name for wireless networking standards. Wi-Fi lets devices communicate by sending and receiving radio waves. In 1971, the University of Hawaii demonstrated the first wireless data network, known as ALOHAnet. In 1985, the US FCC opened the ISM radio bands for unlicensed transmissions. After 1985, other countries followed, and ...
