Air interface compatibility (AI)
The ability for radios of different versions to still communicate. This is related to the air interface
protocols, RF frequencies, modulation methods and channels hopping mechanisms. Firmware with the
same Major and Minor revision numbers are always Air interface compatible. A difference in the Minor
number may indicate some Air interface incompatibility in some modes.
Feature Compatibility (F)
Each version of the firmware usually contains additional features such as protocols, enhancements such
as security coding and changes to the user interface. Modems with different versions of firmware may be
still compatible provided that features of the newest version modem are not utilized.
