What is WiFi
WiFi is the short form of wireless fidelity. It is the wireless interconnections
of all the fidelities in an organization. It's the industry name for
wireless LAN (WLAN) communication technology related to the IEEE 802.11
family of wireless networking standards. WLANs provide wireless network
communication over short distances using radio or infrared signals
instead of traditional network cabling.
Access Point
WLANs are built by attaching a device called the access point (AP)
to the edge of the wired network. Clients communicate with the AP
using a wireless network adapter similar in function to a traditional
Ethernet adapter.
Technologies
Random wireless clients must usually be prohibited from joining the
WLAN. Technologies like WEP raise the level of security on wireless
networks to rival that of traditional wired networks.
To some, the term WiFi is synonymous with 802.11b, as 802.11b was
the first standard in that family to enjoy widespread popularity.
Today, however, WiFi can refer to any of the three established standards
802.11b, 802.11a and 802.11g.
The WiFi Alliance certifies vendor products to ensure 802.11 products
on the market follow the various 802.11 specifications. Unfortunately,
802.11a is not compatible with 802.11b/g, so the WiFi market remains
somewhat fragmented.

Hotspot |
It is the area surrounding the access point of WiFi within fidelity can access the data from the access point.
It is the process of accessing data by any fidelity from the access point within a hotspot without any wire connection.

Bluetooth & WiFi |
Bluetooth and WiFi are both wireless networking standards that provide connectivity via radio waves.
Bluetooth's primary use is to replace cables, while WiFi is largely used to provide wireless, high-speed access to the Internet or a local area network.

Scope of WiFi The WiFi is not only an advantage in the direction of making all fidelities connected wirelessly, but our life on the road has just got a lot easier.
