Unmanned Aerial Vehicles (UAVs) gained a lot popularity during the last years and are used in many applications ranging from reconnaissance over disaster recovery to remote sensing. In most applications some sort of communication link is needed to transmit telemetry and payload data. Especially for homeland security and civil operations the realization is sometimes very demanding due to missing radio...
Based on the recent developments in the area of lithium polymer batteries and carbon fiber-reinforced plastic materials Micro Unmanned Aerial Vehicles (MUAV) have significantly gained in importance. Therefore, the use of MUAV based swarms is a feasible approach for remote sensing, surveillance and in particular for emergency and rescue missions [1][2]. Developing MUAVs which operate at low altitudes...
Based on recent developments in the area of lithium polymer batteries and carbon fiber-reinforced plastic materials Micro Unmanned Aerial Vehicles (MUAVs) significantly gain in importance. One of the challenges in using third party cellular networks for MUAV utilization lies in the directivity of the widely used antennas, which are usually illuminating the ground area but not the aerial user space...
Despite recent advancements in cellular mobile network architectures, full coverage for seamless handoffs is still an open issue. Moreover, cost efficient calls for the end users in urban regions with very high coverage can be improved. In many areas overlapping networks like WLAN, GSM and 3G provide alternative wireless links. Ideally, the user should be connected to the most attractive network any...
