The article discusses the development of next-generation chips that support 4G connectivity. It cites that manufacturers are more cautious in striving to create new technologies which are capable of seamless roaming between three generations of wireless technologies. Moreover, it also notes on the key technological issue of utilizing a different digital modulation which needs a different set of signal processing.
