dBi stands for decibel isotropic, which is a logarithmic unit used to express the ratio between two values of a physical quantity, often power or intensity. DBI can also mean: Davies-Bouldin Index Diazepam binding inhibitor Perl DBI, a database interface for Perl
3G stands for 3rd Generation of cell phone technology and transmission. It is the the IEEE 802.11 protocol for wireless technology
WiFi" stands for "wireless fidelity". This is a marketing name and bares no relation particularly to the technology .
DBI stands for Database Independent Interface. It is a Perl module that provides a database-neutral interface for accessing database management systems. It allows Perl scripts to work with different database systems without needing to change the code significantly.
There are basically ONLY two types of wireless technology: analog and digital. ALL "wireless" technology is radio technology.

WLAN stands for Wireless Local Area Network, and refers to a group of two or more computers connected to the same wireless connection over a short distance. WiFi stands for "Wireless Fidelity" and is actually a trademark name used to used to brand products such as routers, phones, and basically any device that has a wireless connectivity.

To convert dB to dBi (decibels isotropic), you need to add 2.15 dB to the dB value. This adjustment accounts for the difference in reference points used in the two scales. So, if you have a value of x dB, the equivalent value in dBi would be x + 2.15 dBi.
