Crossing over between 3G/4G and Wi-Fi – Seamless and Robust

Not a long ago, when we started talking about small cells, the first question we would always hear was “why do we need small cells, when we have Wi-Fi?” But that has rapidly evolved into “how can we ensure that the interworking between 3G/4G and Wi-Fi is robust and seamless?”

The interworking becomes even more crucial considering the looming 1000x challenge, in which Qualcomm envisions dense deployments of small cells, most of which are integrated with Wi-Fi.
