ParkerVision is engaged in the development of Direct2Data (D2D) and Direct2Power (D2P) technology, based on a platform called Energy Signal Processing (ESP).  ParkerVision claims that this technology is “a wireless Direct Conversion radio frequency ("RF") technology that will reduce cost, size, and power consumption while improving performance of wireless devices such as cellular telephones and wireless local area networks ("WLAN"), among others”.

Efforts that ParkerVision expended into commercializing D2D technology from 1998 to 2004 resulted in a mediocre chipset that was not only late to market, but failed to differentiate itself (see Direct2Digital (D2D) Analysis). The SignalMAX product family of WLAN cards based on D2D chips were more expensive and consumed more power than competing WLAN products, although they offered improved range.  Worse, when analyzed, the SignalMAX design achieved its noticeable improvement in range not from the D2D chip technology, but rather from a high gain antenna manufactured by SkyCross, higher raw power, and redundant receivers! 

In the absence of publicly available datasheets, publications, or white papers on ESP technology, it is difficult for ParkerVision to defend its claims within the RF engineering community, let alone build credibility with the technical gatekeepers at OEMs and other customers.  Surely, given the extensive patent portfolio on which ParkerVision has expended almost $8M to date, Jeff Parker should feel secure enough to divulge the great technical mysteries that will surpass the work of Marconi and usher in a new wireless communications age (see Intellectual Property). 

From recent presentation materials published to date, it is nevertheless possible to glean enough evidence that D2P technology, like its D2D counterpart, is not as revolutionary as Jeff Parker would like us to believe (see Direct2Power (D2P) Analysis).  In fact, it appears more that the company is hiding the fact that the technology is not novel, through obfuscation and silence, rather than celebrate and share their discovery with the technical community.
