ACD Telecom has been involved and active in P25 since its inception in 1989.  Ali Shahnami was a former APCO Headquarters' Director of the Frequency Coordination Department where he was involved and active within P25/TIA committees such as: Encryption Selection, Compatibility and Interoperability between various manufacturers (lockdown committee) and TSB88 documents development. 

As a natural progression from working with public safety agencies nationwide it made sense to retain those core ideals and capabilities in Public Safety Communications.  ACD Telecom has strong background, knowledge and experience in P25 system technology, FCC/FAA rules & regulations, spectrum management and licensing, project management, in-building/on-street coverage testing, RFP development and negotiation, and needs assessment.
