Streaming video to cell phones is natural to all of us today as a normal phone call was before. It is however not that easy to provide the technology solving it for small mobiles RF-paths. Furthermore, everything that aim to be implemented in consumer products must be cost effective, energy efficient and flexible.
Challenges exist, yes:
-There are lots of challenges, says Anders. To push it all and to not fall into trade-off traps is the hardest. Noise, linearity, power consumption, etc must all be treated in and efficient way. There will also always be new requirements that must be taken into account and flexibility of the systems is necessary in order to let it deal with new scenarios. Moreover, as I have learned now towards the end, it's hard to get everything to work when you have lots of different parts of the receiver on the same chip. The last chip I did also had an analog-to-digital converter which posed certain problems. This was something we first discovered during tests, and a phenomenon that we could not reproduce in the simulator.
