  7. 7. Drivers For Next Generation (5G) Growing Population Hyper Connectivity Limited Resources Higher Capacity Green Technology Cost Efficiency Quality of Experience Number of connections and also the volume of data over wireless networks continuously growing at a significant rate Users more demanding on quality & price Capacity challenge is real particularly in radio Radio spectrum the blood line of wireless is a finite resources, scarce and expensive The data volume growth will continue but dependent on the service quality offered by the NW and of course the data tariffs Sustainability of mobile broadband business - Ever increasing traffic, higher TCO and flattening ARPU 3G & 4G both promised improvements in NW capacity, data rate, efficiency, cost and quality. 5G will be no exception but the sheer scale of the challenges this time makes 5G research different.
