Welcome to 5G Mobile Wireless Internet Emerging Technologies Subcommittee
The 5G Technical Subcommittee will focus on exploring and elucidating all facets of the next generation of 5G “Mobile Wireless Internet of Everything” technology, business and societal gaps and challenges between the current 3G-4G-LTE access-only Internet models and the proper vision of 5G, evolutionary or revolutionary, to go beyond just access by embracing and facilitating the upfront integration of all new technologies (IOT, SDN/NFV, Cloud Computing, ..) to be user-transparent, app-oriented, service-ready, ubiquitous and lowest cost.
As Internet usages are proliferating, communications networks are faced with new shortcomings. Future networks will have to support in 2020 mobile traffic volumes 1000 times larger than today and a spectrum crunch is anticipated. Wireless access rates are today significantly lower than those of fixed access, which prevents the emergence of ubiquitous low cost integrated access continuum with context independent operational characteristics. Communication networks energy consumption is growing rapidly, especially in the radio part of mobile networks. The proliferation of connected devices makes it very difficult to maintain similar performance characteristics over an ever larger portfolio of technologies and requirements (i.e.Ultra High Definition TV vs. M2M, IoT). Heterogeneity of access technologies entails unsustainable cost with increasing difficulties to integrate an ever larger set of resources with reduced OPEX. Network infrastructure openness is still limited. It prevents the emergence of integrated OTT (cloud)-network integration with predictable end to end performance characteristics, and limits the possibility for networks to become programmable infrastructures for innovation with functionalities exposed to developers’ communities.
These key issues for the competitiveness of the communication industry world-wide are and will be globally researched in the context of future 5G integrated, ubiquitous and ultra-high capacity networks.
The challenge is to support an anticipated 1000 fold mobile traffic increase over a decade and to efficiently support very different classes of traffic/services. Actions may address the following topics:
– Network architecture, protocols and radio technologies capable of at least a ten times increase in frequency reuse, making possible low cost spectrum exploitation including for new frequency ranges above 3,6 GHz. It covers real time and flexible radio resource allocation as a function of traffic/user distribution with possibility to guarantee and differentiate/prioritize quality of service. The work takes into account novel requirements from cloud networking, from a multiplicity/diversity of connected devices and services to be served and content delivery/cell broadcast/caching requirements. Reduction of energy consumption, significant bandwidth increase in current mobile bands and end-to-end latency are key drivers.
– Versatile low cost ubiquitous radio access infrastructure equally supporting low rate IoT and very high rate (>> 1Gbit/s) access, enabling service access capability over radio links similar to those of fixed access and a fixed-mobile seamless access continuum, and integrating satellite access where appropriate;
– Flexible and efficient radio, optical or copper based backhaul/fronthaul integration with low latency, compatible with access traffic increase and additional signaling increase for multi cell operations;
– Innovative architectures for 5G transceivers and micro-servers, with identification and prototyping of key hardware building blocks supporting low cost implementation of the identified spectrum usage scenarios.
Following impacts are sought:
– 1000 times higher mobile data volume per geographical area.
– 10 times to 100 times higher number of connected devices.
– 10 times to 100 times higher typical user data rate.
– 10 times lower energy consumption for low power Machine type communication.
– 5 times reduced End-to-End latency (5ms for 4G-LTE).
– Ubiquitous 5G access including in low density areas.
The objectives of this committee are to facilitate the worldwide harmonization of research and best practices for deployment user scenarios of the global 5G ecosystem, the built-in security and privacy by design in 5G, and explore the different ways to enable Internet protocols over the next generation of empowered devices in order to reach convergence and end to end transparency through IPv6 (For this purpose, this subTC will be supported by IPv6 Forum www.ipv6forum.org ).
