Cognitive Radio?
Diamonds gleam within the pages of QST and Eclectic Technology (p. 94) October 2008, Vol. 92, Issue No. 10 shines brightly. What is on the horizon? Cognitive radio.
This quote from IEEE Xplore, "The growth of wireless applications and spectral limitations are serious concerns... Cognitive radio technologies expand spectrum efficiency using elements of space, time, and frequency diversity that up to now have not been exploited. An adaptive waveform (AW) generation...adapts to the changing electromagnetic environment and synthesizes waveform features in the frequency domain."
Scientific American.
"Indeed, if cognitive radio technology progresses as its developers hope, a glut of RF-spectrum options may actually arise in time. The airwaves will never be the same again."
Cognitive Radio Technologies.
"Suppose this same radio could remember the locations where your calls tend to drop and arrange for your call to be serviced by a different carrier for those locations."

"This page aims to collect all information related to Cognitive as well as Software, Opportunistic, Dynamic, and such alike radios."
Smart radios and ham radio? Perhaps full deployment of cognitive radio technology is a few years down the road but radio frequency (RF) spectrum is a resource. And demand will push the development of this technology. Have we reached 1-billion mobile users?
On the other hand, what about cognitive radio and RadioSport? One word comes to mind, convergence. CW Skimmer and software defined radio (SDR) like the FlexRadio Systems' Flex-5000C will lead me into a new era in ham radio.
CW Skimmer sniffs RF spectrum, identifies spectrum activity, and frequencies that are not in use as well. The same maybe said of N1MM's bandmap when connected to packet or the telnet. However, my situational awareness is static because visually speaking, I'm only seeing call signs not signal strength or RF spectrum as exemplified by QS1R versatile radio board (VERB) technology.
Read about QS1R VERB technology here, here, and here.
The possibilities of cognitive radio and RadioSport are boundless. Imagine a pop-up message or a synthetic voice saying, "Fifteen meters is now open. Four new multipliers detected." However, I'm in the middle of one of my best rates since the beginning of the contest. Points or multipliers? Perhaps tactical decisions will trend upwards further increasing the complexity of RadioSport. Because of dynamic information that is processed inside the box and displayed on the monitor.
Mine is only a software controlled radio but cognitive radio is leading me in an entirely new direction.
By the way, read my interviews with Gerald Youngblood, K5SDR CEO FlexRadio Systems and Toby, DH1TW for further insight into ham radio's new era.
Until then turn on, tune, and operate.
