Brief history

- 70’s: first research in DoD

- 90’s: success of the SPEAKeasy Phase I and II: first implementation

- 1991: SDR goes to towards civilian applications

- 1995: RFI (Request For Information) on SDR for mobile networks

- 1996: Modular Multifunctional Information Transfer System Forum (MMITS Forum)

- 1998: MMITS was renamed to Software Defined Radio Forum (SDR Forum)

- 2009: SDR Forum was renamed to Wireless Innovation Forum
