“Mobile operators should invest in carrier Wi-Fi networks, and<br />
shouldsubsidize femtocells for their hungriest data hogs, to<br />
resolve their signaling issues associated with smartphone<br />
applications. In addition, operators should aggressively<br />
implement video compression algorithms, core network<br />
offloading, and CDNs in order to cut down on the sheer weight of<br />
the video and web traffic on their backhaul and core networks. In<br />
short, all of the above will be necessary to successfully manage<br />
data growth”<br />

The Key Takeaways from this presentation are:<br />
Mobile architectures are undergoing massive change where the service and<br />
application requirements and the associated bandwidth growth is increasing<br />
incrementally compared to the associated revenues. There is need to<br />
optimise the service delivery and provide new revenue streams.<br />
Convergence is key on an architectural and technology level and MPLS is the<br />
key technology that offers true scalability and flexibility for all service needs in<br />
the future<br />
The LTE/SAE evolution is about evolving towards an “all-IP” vision and<br />
makes demands on the underlying network with advanced intelligence<br />
needed<br />
<strong>Cisco</strong> is uniquely positioned to address these Wireline and Wireless<br />
requirements with its converged CE architecture supporting both legacy and<br />
evolving technologies<br />
