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
