Today, we see numerous communication systems, from WiFi routers to bulky towers, but all of them require conventional power sources, wires and infrastructure, consuming a lot of resources and occupying a lot of space. The deployment of such communication systems disregards the overall aesthetics of the environment, giving an unappealing impression. The devices manufactured from non-biodegradable materials produce a lot of e-waste. In a nutshell, the current solutions seem inconsonant with the vision of future smart cities, especially in the context of Internet-of-Things (IoT) age. SmartWindow represents a unique and creative approach towards providing data connectivity by employing glass windows in our homes and offices as a communicating node, powered by solar energy. The concept of embedded technology is employed to develop a novel technique for mounting a communication module on a window. The SmartWindows form a cooperative communication network in a neighborhood, providing seamless data connectivity. Compared to the existing solutions, SmartWindow is 50% more energy-efficient. The materials used for manufacturing are 65% biodegradable, significantly reducing the e-waste. It presents an easily deployable solution, where users will just buy the SmartWindow module and paste it on their window to enjoy the services. Itâ€™s a â€œpaste-and-playâ€ solution. The most exciting feature is the customizable antenna design that blends in well with the dÃ©cor of the house. The users could have the design of their choice printed on the window, e.g., a beautiful scenery, creating a wonderful fusion of art and technology, providing a unique experience. It is estimated that the number of internet users will rise to 4 Billion by 2020. SmartWindow could revolutionize the way we connect in future, providing a creative, sustainable, unique and artistic solution to network connectivity. SmartWindows could be a key to Smart cities, aiding the deployment and operation of 5G IoT.
