What is the difference between broadband and Wi-Fi?
What is broadband?
Confusion also exists between broadband and mobile Internet, broadband without phone line no contract, Broadband is a home internet connection and it is wired. While mobile “broadband” uses 3G, 4G, or 5G to connect directly to the Internet through a mobile operator's network. Until very recently, almost every household had a router or modem that provided a connection to the so-called broadband Internet. This connection can be provided by your telephone line (ADSL), by a wired connection, or even by an optical fiber. A relatively recent development in changing the speed up fixed-mobile rate. This time a modem or router uses a 4G or 5G wireless connection to provide a connection to the Internet. In rural areas, broadband can be provided by satellite. But in general, when using a phone, tablet, or laptop at home, every device will connect to that router over WiFi. It is only if the PC, the game console, or the decoder are not equipped with WiFi that they will connect to this router or to this modem by a network cable. It is for this reason that some people speak indiscriminately about WiFi and broadband.
What is WiFi?
Essentially, WiFi replaces the traditional Ethernet network cable with radio waves. Many think of this connection as a wireless internet connection, no contract broadband without landline, but WiFi simply connects two devices on a network without going through a cable. WiFi is therefore not the Internet, and it simply allows Internet traffic to be transmitted wirelessly to a smartphone or other terminal. WiFi does not mean Wireless Fidelity. It is a mistake. WiFi is just a name for the official IEEE 802.11x standard. The "x" suffix can take any value. It means WiFi covers all WiFi standards, the latest being 802.11ax. Because this reference is too long and too confused, the Wi-Fi Alliance has developed a new naming system easier to understand, to e so that e the new name of 802.11ax is WiFi 6 and 802.11ac is WiFi 5.

broadband Internet through the light!
A few years ago we learned about Bluetooth, a revolutionary technology that allowed us to send and receive files at a reduced distance and at low speed. Then came the time of WI-FI, this technology that we find everywhere and which is now part of our daily lives.
Light technology
Acronym for Light Fidelity, Li-Fi uses LED lighting to transmit content (radio, videos, photos, files, etc.) to a computer, smartphone, tablet.
It's faster than anything we've known until today! Li-Fi uses a transmitter and a receiver like all wireless technologies. Radio waves are replaced by harmless light spectra. So, we still need an electricity meter as well as an electricity contract for this technology.
Li-Fi is not yet established, but it already has practical and health benefits. In addition to being 100 times faster than Wi-Fi, Li-Fi does not create electromagnetic waves that may interfere with other devices and harm our health and make life easier for electro-sensitive people. Li-Fi would therefore be usable in the fields of defense, cheap broadband without contract, health, and aeronautics thanks to this absence of waves.
