Shaping coverage using antenna arrays for load-balancing in cellular networks
Keywords:antenna arrays, wireless network, pattern synthesis, adaptive cellular coverage
AbstractIn this article the authors investigate shaping coverage cooperatively in a macro-cell environment and evaluate the benefits using real antenna models. Each antenna in this proposed scheme is an adaptive array equipped with the capability to re-configure and shape power patterns through power pattern synthesis. Patterns are formed cooperatively to control coverage and balance and maximize overall network capacity. A range of antenna models are tested in this article using an ideal optimal synthesizer and verified using a system-level WCDMA simulator. The results are analyzed to show the requirements and desired features of the antenna system.
