Title: The Innovations of Per Wijk
Introduction
Per Wijk is a notable inventor based in Gothenburg, Sweden. He has made significant contributions to the field of wireless telecommunications. With a total of 2 patents, Wijk's work focuses on improving the efficiency and performance of mobile communication networks.
Latest Patents
Wijk's latest patents include "Adaptive handoff hysteresis in wireless telecommunication networks." This patent describes a method for setting the appropriate hysteresis for cells in a wireless telecommunication network. The goal is to reduce the rate of oscillating handoffs that occur when a mobile station transitions from one cell to a neighboring cell. The method involves measuring the received signal strength in the originating cell and at least one neighboring cell. The hysteresis is calculated using statistical operations, such as the standard deviation, applied to the received signal strengths. This calculated hysteresis value can be manually adjusted by the operator or input into self-configuring cells for dynamic adjustment, enhancing network performance.
Another significant patent is the "Method and system for variable handoff hysteresis in radiocommunication systems." This invention outlines a method for performing handoffs using a time-variable hysteresis value. By adjusting the hysteresis value based on the duration of the mobile station's use of a current channel, the invention addresses issues related to signal strength measurements that arise from filter initialization.
