dWiFi – STL’s converged WiFi platform for addressing data management challenges

Introduction – Data management challenges faced by Telcos

One of the key challenges for Telcos today is mobile data traffic growth. Growth in smart devices (smart phone and other network connected devices) is the leading driver for this and is estimated to lead to 12.3 billion mobile connections by 2022. We are also witnessing IoT devices growing dramatically, it is estimated that there will be 41.6 billion connected IoT devices, or “things” generating 79.4 zettabytes (ZB) of data by 2025. As we get more and more connected, customers are starting to demand always-best connectivity. Some of the most common demand includes – best connected user experience anytime, anywhere, ability to switch seamlessly between devices and connections, and improved performance for high-definition streaming apps. Cellular services have suffered from spotty connections, high spectrum costs and rising network infrastructure costs. Telcos, in order to meeting changing customer needs, are forced to look beyond cellular today. Augmenting cellular networks with WiFi networks has emerged as a potential solution to overcome the data tsunami and enhance user experience. But challenges like supporting different user scenarios like airports, in-flight, transit, public hotspot etc. with seamlessness, scale and monetization opportunities, still need to be overcome.
