Hello all I am Kritesh and in this blog we will learn about WIFI,WIFI also Spelled
as Wi-Fi is a local area wireless technology. It allows an electronic device to
transfer data or connect to the internet using ISM radio bands. ... Wi-Fi is
the trademark of the Wi-Fi alliance and used as a brand name for products
using the IEEE 802.11 standards. Wi-Fi is a wireless networking technology that allows
devices such as computers (laptops and desktops), mobile devices (smart phones
and wearables), and other equipment (printers and video cameras) to interface
with the Internet. It allows these devices--and many more--to exchange information
with one another, creating a network.

What is portable Wi-Fi hotspot?
A
portable Wi-Fi hotspot is a mobile hotspot obtained through a cell phone
carrier. It's a small device that uses cellular towers that broadcast
high-speed 3G or 4G broadband signals. Multiple devices, like iPads and
laptops, can then connect wirelessly to the device, which in
turn seamlessly connects to the Internet where ever you travel. Similar to
a cell phone, the portable hotspot's monthly cost is based on the data usage
plan you select. A portable Wi-Fi hotspot is a more reliable way to access the
Internet than searching for static public Wi-Fi hotspots.
What
is a mobile hotspot?
A mobile hotspot is a common feature on
smartphones with both tethered and untethered connections. When you turn on
your phone’s mobile hotspot, you share your wireless network connection with
other devices that can then access the Internet.

How
does Wi-Fi work?
On the technical side, the IEEE 802.11 standard
defines the protocols that enable communications with current Wi-Fi-enabled
wireless devices, including wireless routers and wireless access points.
Wireless access points support different IEEE standards.
Each standard is an amendment that was ratified
over time. The standards operate on varying frequencies, deliver different
bandwidth, and support different numbers of channels.
