Fantastic-5G 5G-PPP Project On 5G Air Interface Below 6 GHZ
With 4g being currently massively rolled-out, it becomes apparent, that while it is very well suited to serve the wirless communication need of today, it will quickly reach its limits. This is obvious due to the following obsverable trends:
- Mobile BroadBand (MBB)
- Massive Machine Communications
- Mission Critical Communications
- Broadcast / Multicast Services
- Vehicle-to-infrastructure Vehicle-to-Vehicle
Detailed information is available in the FANTASTIC-5G EuCNC 2015 paper.
5G-PPP Project on 5G Air Interface Below 6 GHz
The next generation (5G) celluar technology is expected to arrive in 2020. There are four trends indicating the need for a new generation of celluar technology including new air interfaces:
- Efficiency in terms of resource utilization (e.g. energy, spectrum) is becoming more and more pronounced. It is seen as an indispensable ingredient for a healthy/sustainable (1) ICT market/business and (2) environment
- The demand for wireless data is predicted to increase significantly, resulting in 1000x hight mobile data volumes and 10-100x higher end user data rates.
- The number of connected devices is predicted to increase by a factor of 10-100, which means that up to 300,000 devices need to be served per access point.
- Wireless connetivity will be applied to new use cases that require very liable connections and mission-critical communication, such as vehicle-to-vehicle coordination, critical control of the power grid, etc.
- Remote presence and tactile Internet that impose stringent latency constraints on the overal connection, including the wireless part of it. Forecasts imply that the latency should be decreased for a factor of 5 in order to enable such services.
The air interfaces for 2G, 3G and 4G were all designed for specific use cases (limited only to voice and data comuncations) with a certain number of limited KPIs in mind (throughout, capacity, dropped/blocked call rates, etc.). However, as outlined above, 5G requried the support of a much broader class of services and consequently a very diverse family of devices an traffic characteristics. FANTASTIC-5G is a European project which will develop a new multi-service Air Interface (AI) for below 6 GHz through a modular design. To allow the system to adapt to the anticipated heterogeneity, the pursued properties are: flexibility, scalability, versatility, efficiency and future-proofness. To this end, the project will develop the technical AI components and integrate them into an overall AI framework where adaptation to the above described sources of heterogeneity will be accomplished. The work will also comprise intense validation and system level simulations. The consortium possesses the main stakeholders for innovation and impacting standardization, maintaining Europe at the forefront.
