Title
(EN) DIGITAL MICROWAVE RADIO SYSTEM AND METHOD WITH ENCRYPTION
(FR) FAISCEAUX HERTZIENS NUMÉRIQUES ET PROCÉDÉ AVEC CRYPTAGE
Abstract
(EN)
A communications system are provided that provides integrated encryption capabilities. In particular, a digital microwave system, terminal and method are provided in which the encryption functions are integrated into the digital microwave terminals. The digital microwave system may also be implemented with external encryption units.
