Motorola Products > Project P25 Terminals & Infrastructure > Over-the-air Rekeying (OTAR)



Solve the logistical problem of maintaining secure wireless communications and eliminate the burden of manually rekeying your radios on a regular basis. Project 25 (P25) compliant OTAR is part of a powerful suite of ASTRO® 25 applications designed for radio and network management that enables key distribution and key management to be conducted securely over-the-air.
