On Indoor Mobility Performance Limits for an Engset Radio-over-Fiber Model Using Prioritized General Handoff Process

摘要

The application of Radio-over-Fiber (RoF) technology in cellular systems has attracted considerable attention in recent time. Consequently, the indoor personal communication systems (PCS) using the RoF architecture needs reinvestigation in performance domain. In this paper, we investigate such a system, which uses tiny cells (pico-cells) with limited number of users. We develop a corresponding traffic model for state dependent fresh call requests (Engset distribution) from limited user population. The model, in addition, considers frequent handoffs of users, which is not necessarily a memoryless random process. The model has a provision of channel reservation for handoff calls thereby prioritize the handoff process. The proposed model is computationally efficient and simple to implement. Further, it is effective to determine the optimum level of reservation in system design.
