A method for 4G node frequency selection describes a mechanism for automatically selecting the frequency of a newly installed base station, thereby optimizing the throughput per area unit of the newly installed base station in its predefined vicinity area. The method is based on an iterative calculation approach, which combines real-world network and base station measurements information with the nominal specifications of the newly installed base station (antenna diagram, output power) and the location and direction thereof.

COBISS.SI-ID: 7954772A method for cognitive neighbor selection in 4G networks describes a mechanism for automatic self-learning selection of neighboring base stations for the purpose of providing seamless handoffs in a dense deployment of pico and macro base stations. When a 4G network is modified by adding new base stations, the optimum handoff thresholds and advertised base station neighbors are automatically recalculated in a manner that reduces the number of unnecessary handoffs in a dense network with large number of pico and macro base stations.

COBISS.SI-ID: 7954004This invention aims to avoid and resolve congestions in wireless 4G networks. The method is based on a central self-organizing network (SON) server, which dynamically changes neighbor lists on congested base station and on all base stations in vicinity. The procedure is triggered by measuring relative committed traffic rate and air interface utilization of the base station.

COBISS.SI-ID: 8064340State of the art timing and synchronization system with femtosecond precision is presented. Proposed electro-optical synchronization system consists of the transmitter, located at the place of the low-jitter master oscillator and the receiver (Rx), located at the remote location. Both units are connected with a singe-mode optical fiber pair in a loop-back to achieve phase-noise and phase-drift compensation. It makes use of standard, commercially-available telecommunication optical components. The added timing jitter of 5 fsRMS has been measured on the first experimental tests.
