Title: Innovations of James Edward Dalley

Introduction

James Edward Dalley is a notable inventor based in Harlow, GB. He has made significant contributions to the field of telecommunications, holding a total of 5 patents. His work primarily focuses on enhancing cellular communication networks through innovative antenna designs and estimation methods.

Latest Patents

One of Dalley's latest patents is the Multiple Beam Antenna, which addresses the limitations of capacity increases in cellular communications networks. Traditionally, increasing the number of main antenna beams did not yield a proportional increase in capacity. Dalley's invention describes a multiple beam antenna arrangement that ensures the increase in capacity is commensurate with the number of antenna beams provided. For instance, his nine sectored tricellular CDMA network utilizes a multiple beam antenna arrangement with six antenna elements arranged in columns. This design employs a 6×6 Butler matrix beamformer, which is advantageous due to its lossless nature. Additionally, the arrangement allows for the sharing of power amplifiers, thereby reducing costs and complexity.

Another significant patent is the Cell Radius Estimation Method. Current methods for estimating radio telecommunications cell radius often yield inaccurate results, particularly in areas with poorly sampled signal measurements. Dalley's improved method utilizes path loss and signal source distance data to provide more accurate cell radius estimates. By applying a fixed gradient line fit to the data, his invention enhances accuracy and reduces costs in network planning applications.
