IEEE 802.11g
IEEE 802 is better than the IEEE 802.11b version. When the comparison takes place between IEEE 802.11b and IEEE 802.11g obviously the 'g' has the advantages over the "b". In the IEEE 802.11g there is no better protection mechanism, where as it is written into the 802.11g standard. But therein lays the problem: When devices are released before the standard is ratified, equipment vendors can conveniently ignore such protection measures.802.11g is an easy choice for corporate sites and home users to adopt because it doesn't require an upgrade to client equipment. 802.11g is backward-compatible with 802.11b, and it offers speeds similar to those of 802.11a.

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.
