Sometimes, it might be easier to first have a idea of starting something new then go to look for a job.
In my years of pursuing my PhD degree, I have been looking into a thing called dynamic spectrum access, an application that is always tightly connected to cognitive radios. After years of advocating, it is still a futuristic idea.
Where will the demand for more wireless bandwidth meet the reality?
Not at home/office. Everyone has Internet at home. Femtocell offloads 3G connections to DSL, cable or fiber.
Not at any place with ample WiFi access points. So long as WiFi is deemed fast enough, other technologies cannot beat that. Fortunately millions of people are developing applications to increase the bandwidth demands of billions of people. WiFi speed cap is still way above any Internet connection speed.
How much Internet connection and how much local connection?
The opportunity is huge if we can provide on-the-road bandwidth. Currently, either music radio in passenger vehicles or video news on public transportation. 3G is far from sufficient. 4G is in deployment, which requires large investment. VANETs are suitable for provide local connections. Not necessarily Internet connection. What can we do with that?
