What is WiFi ??
WiFi, which stands for Wireless Fidelity, is a wireless communication technology used for local area networks. Today’s laptops, smartphones, tablets, cameras and even televisions are made up of WiFi modules, making it a widely used technology for home networks. In addition, all common operating systems, such as Windows, Linux, OS X, iOS and Android, support WiFi, which makes it easy to connect via WiFi. WiFi uses the airwaves electromagnetic as support, the frequency band used being 2.4 GHz.
IEEE defines a protocol called 802.11 which indicates how the exact communication takes place. Several versions, such as 802.11a, 802.11b, 802.11n, 802.11g and 802.11ac, have been introduced in the order that different protocols support different speeds and ranges.
What is Hotspot ??
A hotspot is a place that provides Internet access via WiFi. A wireless access point is created using a device called an access point. In general, the access point and the access point can mean the same thing. An access point is usually a device connected to a router or gateway, connected to the Internet. The access point allows various devices to connect via WiFi and provides them with the internet via the router to which it is connected. In modern wireless routers, the router and the access point are integrated into a single device.
WiFi hotspots are located in public as well as private places. Today, many public places around the world, such as airports, shops, restaurants, hotels, hospitals, libraries, public telephones, train stations, schools and universities, have hot spots. Many offer free Internet access, but there are also commercial networks. Hotspot can also be set up at home by simply connecting a wireless router to the Internet via ADSL or 3G. It is the most common technique used today to share the Internet connection at home on different devices.
Aside from computer hardware, software can also create hot spots. Software such as connectify me, a virtual router and tools integrated into operating systems allow you to share the Internet by transforming the Wi-Fi module of your laptop or mobile phone into a virtual access point.
What is the difference between WiFi and Hotspot?
- WiFi is a wireless communication technology used for local networks. It is used to interconnect devices in order to make proper communication. A hotspot is a place that provides Internet to wireless devices using WiFi.
- An access point is created using a device called an access point. The access point is connected to a router serving as a gateway to the Internet. WiFi is used between the access point and the wireless device for interconnection.
- WiFi uses electromagnetic waves in the 2.4 GHz radio frequency band to establish communication. An access point uses this WiFi technology to interconnect devices to a single point called an access point to share the Internet.
- A hotspot is created using Wi-Fi, but not vice versa. Without Wi-Fi, there will be no hotspots.
- Hotspot is a place that provides Internet access for wireless devices. Wi-Fi technology, on the other hand, involves protocols, specifications, hardware, and drivers.
Summary:
Wi-Fi vs Hotspot
Wi-Fi is a technology used to interconnect devices on a local network. It is a wireless communication technology using radio waves. A hotspot uses Wi-Fi technology to provide Internet to wireless devices. So a hotspot is a place that provides Internet to wireless devices using Wi-Fi as a local area network technology.
