Technologies for the Wireless Future: A View from the WWRF

Professor Sudhir Dixit

WWRF (Wireless World Research Forum) is developing a common global vision for the future of wireless to drive research and standardization. In addition to influencing regional and national research programmes (such as the European Union’s FP7 programme), WWRF members contribute to the work done within the ITU, UMTS Forum, ETSI, 3GPP, 3GPP2, IETF, and other relevant bodies regarding commercial and standardisation issues derived from the research work. The Forum is unique in bringing together industry and academia from across the globe, with a strong focus on emerging economies. Members discuss how new insights will affect network implementation, services, applications and value chains in the future. It provides a unique networking opportunity, by attending its meetings, contributing to the work on the working groups, and by joining the Forum. After a brief overview of the Forum and its activities, we present the view of the WWRF how the wireless world might look like in the year 2020. On the services side, we anticipate the following evolutions to happen in the evolving digital society: (1) from voice to data, (2) from pipe to content, (3) from people to machines, (4) from ICT to ICT using cloud-based services. On the network side, we anticipate that 4G/LTE would be ubiquitous with some deployment of LTE Advanced. From the devices perspective, most users would be carrying smart phones and tablets with the services and content residing in the cloud and these devices would provide a window into the physical world through digitalization of the information. Security and privacy would be extremely important and challenging to accomplish in the world of Web 3.0 inundated with a lot of private data and multimedia content from all types of sources. Spectrum scarcity will be quite real giving birth to band sharing and possibly deployment of cognitive radio (including coordination and multisite MIMO) and cognitive networks all over the world. Increasing scarcity of power would give a major push to green radio and more efficient energy aware software architectures and device components that would allow the mobile devices to function for up to a week or more on a single charge with the ability to charge from the ambient environment.
