A Handover scheme based on Moving Extended Cells for 60 GHz Radio-over-Fiber networks

摘要

We demonstrate a handover scheme for supporting high end-user mobility in a 60 GHz broadband picocellular Radio-over-Fiber network. The proposed scheme relies on a novel Moving Extended Cell (MEC) concept which is based on user-centric virtual groups of adjacent cells that transmit the same data content to the user. The MEC concept utilizes a mechanism for restructuring the virtual multi-cell area according to the user's mobility pattern, so that a virtual antenna group moves together with the mobile user. A mathematical model is developed and performance evaluation is also conducted and presented, demonstrating zero packet loss and call dropping probability values in high-rate wireless services for a broad range of mobile speeds up to 40m/sec and independently of the fiber link distances.
