The Wireless communications, besides providing the last mile access and the vital mobility, revolutionized the way we communicate. The other area of ICT to revolutionize the communication is Internet of Things (IoT). These areas have been experiencing vibrant research and technology development activities. The Global Wireless Summits (GWS) were held at two different locations earlier brought together wireless media communication/personal communication, etc.

The third in series of the Global Wireless Summit, the GWS-2015 organized with two major conferences namely 18th International Symposium on Wireless Personal Communications (WPMC) and 5thWireless VITAE, which was held in Hyderabad (India) during December 13-16, 2015.
