Communication technologies and systems, be it wired such as fiber-optic transmission links or wireless such as our personal devices, have evolved tremendously over the past decades and are essential in our work and everyday life. Future challenges include how to further increase capacity while at the same time not adding significant cost and energy consumption. 

The Internet as we know it could not exist without fiber-optic backbone systems. Recent laboratory demonstrations show that it is possible to transmit data at a rate of over 60 Tb/s over oceanic distances in a single optical fiber. So-called spatial division multiplexing could 100-fold this capacity in the future, approaching 10 Pb/s.

Optical systems are also increasingly used in very short links, e.g. for interconnects in supercomputers where energy consumption and footprint is a priority. Photonics could replace metal based transmission also over very shorter distances, millimeters or below, e.g. on computer chips.

Such a development requires new breakthrough in photonics:  Smaller device footprint, smaller than the wavelength of light, and lower power dissipation in switching and routing operations, developments that are currently underway.  

 The fifth generation of wireless communication will realize the full communication needs for the Networked Society. These networks should be run and deployed in a sustainable and cost efficient way and they should be an agile platform for new applications, new players and new services. They will enable massive machine type communication (e.g. road sensors), critical machine type communication (e.g. robot surgery), mass market personalized TV and much more.

Wireless communication between vehicles will enable future traffic safety and traffic efficiency application. By exchanging information in a timely and reliable manner, vehicles can warn drivers about dangerous situations by automatic braking and steering. In the future, we will also enjoy other types of automated driving, e.g., platooning to save fuel, reduce emissions and travel time. 

The workshop will give an overview with different perspectives of the recent developments and upcoming challenges of the technologies for wired (optical) and wireless communications.
