There are multiple communication technologies such as WiFi, Bluetooth, and Zigbee that can be leveraged by a range of devices to communicate with each other. Innovations such as Internet of Things (IoT) add another layer of complexity to the connected ecosystem. This makes interoperability absolutely imperative for the success of this connected world. This white paper discusses the various interoperability issues that are encountered when leveraging technologies such as WiFi and Bluetooth and the ways to address them. It also talks about why interoperability is highly critical for mobile devices and how various companies are incorporating WiFi and Bluetooth services in their devices.
