The document discusses the Internet of Everything (IoE) and connectivity challenges. By 2020, it is estimated that over 25 billion devices will be connected. The IoE brings challenges around discovering devices, identifying services, adapting to changes, managing diverse networks, enabling interoperability across operating systems, and securing connections. The AllJoyn framework and Wi-Fi connectivity help address these challenges by allowing smart devices to connect, interoperate and work together across brands and categories. The Qualcomm XSPAN Wi-Fi portfolio, including the QCA4004 system on chip, aims to enable ubiquitous connectivity for the IoE. Development tools are provided to help build applications for hostless "smart things."
