CTIA Wireless 2009 – Going Green
The International CTIA WIRELESS 2009 event is where broadband communications come to life as the event was branded as “Mobile Life”. It embodied this name as new technologies rolled out to make broadband more widely adopted and seamless but another overriding theme was “Green Technology” especially when your featured keynote is Al Gore.
CTIA Wireless had over a 1000 exhibiting companies and tens of thousands attendees from over 125 countries that converged to do business, discuss innovation and exchange ideas. But the economic slowness definitely affected the attendance and enthusiasm. Some of the buzz was around new phones, the Blackberry apps store, A-GPS and the day two keynote about the merging of wireless with medical applications. The impending stimulus funding to expand broadband services around the US was also a hot topic.
Al Gore was the final keynote speaker and reviewed the history of information distribution and how it has affected the balance of power from the few to the many. He stated there were only 50 web sites online about the time Clinton and he took office compared to today where there are billions. He drove the concept that we have a climate change, security and economic crisis. The common thread in these is our reliance on carbon based energy so we must act quickly to move away from that situation. He stated that wireless is a key tool to solving these problems and challenged everyone to contribute and lead the effort.
Microwave Journal established the first RF Microwave Pavilion that was successful but the overall economic concerns tempered that success. Our sister publication, Telecommunications Group, ran another successful M2M (machine-to-machine) Pavilion. The traffic was moderate, but the quality of inquiries was very good.
Below is a wrap up of the products and services various RF/microwave companies were featuring at the show:
Microwave Design, Materials, Components & Systems:
