- I've enjoyed your arguments against PRKR and am glad you bought in knowing the facts. I was a little interested in finding out some more on the opposing company which you believe has a better technology than PRKR in direct conversion/software radio...How do you know this to be so when D2D hasn't even fully shown what it is capable of yet and what does this new company potentially do better ?
The technology is based on a new multicarrier protocol that is actually used to build other communication protocols. This means that TDMA, CDMA, OFDM, etc will have the same underlying signal architecture. It uses superposition between carriers to build complex baseband signals. Thus, it uses slow parallel processing to achieve extremely high data rates. Downconversion is achieved simply by selecting which carriers to receive and combining them. The underlying architecture simplifies transmitter and receiver designs and greatly increases both bandwidth efficiency and bit error rate simultaneously for any protocol. Thus it is adaptable to different frequencies AND different protocols. It also leverages their own implementation of Cisco's VOFDM technology. They claim bandwidth efficiency improvements of several orders of magnitude.
Considering that the technology is based on new developments in quantum computing and wavelet theory, it really caught my attention. They are presenting a paper on this at the International Conference on Communications in New Orleans (6/18-6/24).
A private company developed this through several universities. Although they have big sponsors, I think a commercial implementation of this is still in the works.
Ultimately, getting a product to market is more important than the technology. It is certainly more important than getting into legal battles in the interference court. That is my main reservation about PRKR and the law firm that represents them.
