| DBI |
Decibels isotropic, a relative gain measurement with respect to an isotropic radiator in free space (uniform emitter in free space, a theoretical situation). Normally used to describe gain for antennas operating at 1GHz or above.

| DBI |
A ratio, measured in decibels, of the effective gain of an antenna compared to an isotropic antenna. The greater the dBi value, the higher the gain and, as such, the more acute the angle of coverage.
