  2. 11. Millimeter Wave Imaging and Phased Array Antennas for 5G and Aerospace Applications

    Author : Jakob Helander; Teoretisk elektroteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; phased array; Millimeter wave antenna arrays; millimeter wave imaging; Computational Electromagnetics; Non-destructive testing NDT ; compressive sensing;

    Abstract : Phased array antennas are cornerstones in many proposed antenna solutions concerning the next generation of both airborne radar systems and wireless communication systems (5G). Additionally, millimeter wave (mm-wave) frequencies are expected to play an integral role in 5G, and are deemed well-suited for inspecting structural components used in the aerospace industry.

    Author : Charitha Madapatha Madapathage Don; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic geometry; Node selection; Beyond 5G; Backhaul; 6G; Blockage; Coverage probability; Poisson point process PPP ; Integrated access and backhaul IAB ; Relay; Constrained deployment; 5G new radio NR ; Tree foliage; Millimeter wave mmWave communications; Densification; 3GPP; Wireless backhaul; Routing; Genetic algorithm GA ; Topology optimization;

    Abstract : Enabling network densification to support coverage-limited millimeter wave (mmWave) frequencies is one of the main requirements for 5G and beyond. It is challenging to connect a high number of base stations (BSs) to the core network via a transport network. READ MORE

  6. 14. Agile, Resilient and Cost-efficient Mobile Backhaul Networks

    Author : Forough Yaghoubi; Lena Wosinska; Marija Furdek; Jiajia Chen; Amitava Mukherjee; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; software defined networking; rain disturbance; technoeconomic framework; network consistency.; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : The exponentially increasing traffic demand for mobile services requires innovative solutions in both access and backhaul segments of 5th generation (5G) mobile networks. Although, heterogeneous networks (HetNets) are a promising solution for the wireless access, the backhaul segment has received considerably less attention and falls short in meeting the stringent requirements of 5G in terms of capacity and availability.
