Most-asked questions
Are all police going encrypted by October 2026?
No. There is no federal mandate. The encryption wave is driven by state DOJ memos and individual agency policy, not a nationwide deadline.

Project 25 (P25) supports optional AES-256 encryption. Phase I uses FDMA, Phase II uses TDMA. No consumer scanner can decode AES-256 P25 traffic.
