CDMA set to fade, What could be the possible reasons for arguably a superior technology to die down?

CDMA can be considered as a superior Technology? I think yes, considering superior voice and data security, higher data speeds, spectrum efficiency.

The roadmap to merge with LTE is well in place. Nortel, one of the last major CDMA vendors declared its technology to seamlessly integrate existing CDMA networks into 4G LTE networks. However, with Ericsson- a GSM major, buying Nortel's CDMA and LTE business; it is not clear as to what will happen with this innovation.

The roaming hassles are history which hampered the growth during internationalization of Telecom.

Guess this is not the reason for decline, apart from Qualcom's approach to continue charging patent fees ignoring the long term sustainability of technology and associated revenues. I think this is owing to the competitive advantage build by European nations to support Telecom Vendors establish standardized GSM networks and expand the same across Asia where cost for subscriber is a governing factor for success.
