The road to 100 Gb/s wireless and beyond: basic issues and key directions

Abstract

This work addresses the blueprint of shortrange wireless systems supporting data rates of 100 Gb/s and beyond. A number of usage models are identified for such ultra-high data rates, including wireless communication within electronic equipment enabling possibilities such as wireless reconfigurable chip-to-chip communication. The 300 GHz band spanning about 55 GHz of contiguous bandwidth is identified as the most suitable candidate to accommodate these bandwidth- demanding applications. Furthermore, the main bottleneck issues are discussed: power consumption and antenna integration. With the help of basic link budget considerations, we indicate the technical feasibility of the proposed concept with compact low-cost antenna solutions. Finally, we discuss the overall system architecture to be standardized and indicate a number of key research topics.
