Increasing Cellular Network Energy Efficiency for Railway Corridors
Adrian Schumacher, Ruben Merz, Andreas Burg
Modern trains act as Faraday cages making it challenging to provide high cellular data capacities to passengers. A solution is the deployment of linear cells along railway tracks,…
Adding Indoor Capacity Without Fiber Backhaul: A mmWave Bridge Prototype
Adrian Schumacher, Ruben Merz, Andreas Burg
Today, a large portion of the mobile data traffic is consumed behind the shielding walls of buildings or in the Faraday cage of trains. This renders cellular network coverage from…
A mmWave Bridge Concept to Solve the Cellular Outdoor-to-Indoor Challenge
Adrian Schumacher, Ruben Merz, Andreas Burg
Wireless indoor coverage and data capacity are important aspects of cellular networks. With the ever-increasing data traffic, demand for more data capacity indoors is also growing.…
3.5 GHz Coverage Assessment with a 5G Testbed
Adrian Schumacher, Ruben Merz, Andreas Burg
Today, cellular networks have saturated frequencies below 3\,GHz. Because of increasing capacity requirements, 5th generation (5G) mobile networks target the 3.5\,GHz band (3.4 to…
Cross-layer Energy-Efficiency Optimization of Packet Based Wireless MIMO Communication Systems
Christian Senning, Georgios Karakonstantis, Andreas Burg
Energy in today's short-range wireless communication is mostly spent on the analog- and digital hardware rather than on radiated power. Hence, purely information-theoretic consider…
