In the other corner is 3G (and coming soon .4G and LTE)
a well established wireless network in developed countries.
3G has evolved from the voice-centric telecoms world but is able to deliver not just voice but high-speed broadband access as well.
The last ten years have seen the growth of huge networks in the developed word and emerging nations are catching up rapidly.
China is investing billions of dollars in rolling out a nationwide 3G network that will reach 70% of the population and the Asia Pacific region expects to have over 500 million 3G subscribers in the next few years.
