Communication theory is one of the few in engineering that actually has a set of known, computable boundaries for optimum system performance, which boundaries serve [...]

After  Clearwire announced it was changing its 4G plans to replace WiMax with LTE, and Sprint was aligned in that decision, the pundits and wise [...]

In some outposts of the wireless engineering community, “cognitive radio” (CR) and “software defined radio” (SDR) are sub-disciplines used in common practice, just like “artificial [...]

We have been hearing so much about Cognitive Radio (CR) technology, we wondered if it really is a significant research topic. Is CR anything more [...]

On 2-25-10 we moderated a panel session of the Cognitive Radio Special Interest Group within the Wireless Communications Alliance. WCA is a Silicon Valley based [...]

Cognitive Radio architectures and implementations require advanced signal processing. While the algorithms can be implemented in software, of course, the ability for RF systems to [...]

We can cool the speculation about WiMax vs LTE, at least for a while. Clearwire’s deployments of WiMax have led to about 173,000 subscribers in USA [...]
