Originally, in 2002 and 2003, ParkerVision claimed that it would sell OEM chips based on its D2D technology.  Such sales never materialized.  ParkerVision then announced in 2004 that is was going to focus on D2D technology and brought wireless LAN cards to the consumer market.  ParkerVision announced a variation on D2D called D2P in January 2005. It shut down its efforts in consumer wireless products in the summer of 2005, and in the second half of 2005, ParkerVision announced in 2004 that it was going to focus on bring D2D technology into wireless LAN products for the consumer market. In the second half of 2005, ParkerVision announced that it was exiting the consumer market. In January 2005, the company announced D2P, a variation on D2D, and declared that it would focus on OEM sales of chips. A year later, the company has not reported any D2D or D2P design wins. In the last 4 years, the company has therefore come full circle in its business strategy, without any meaningful success or traction based on multiple tactical plans.
