Efficient Frequency Reuse for Broadband Wireless Access with Sectored Cells in Offshore Territory

Abstract

Due to the physical constraint in offshore territory, cell placement to the certain location is not always possible. Because it requires high telecommunication tower or tall building/platform to avoid the curvation of the earth in order to communicate with the distant Customer Premises Equipment (CPE) terminals. Hence, applying the concept of cellular network design to cover all service area in offshore territory without outage area or coverage gap is very difficult to be achieved. Hence, the typical frequency reuse with omni-directional cells in cellular networks is not much practical in this area. In addition, using omni-directional cells can incur lower capacity and shorter transmission range compared to the sectored cells. In this work, efficient frequency reuse is considered in only sectored cells. With proper network design in terms of transmission direction and power, it can guarantee that there is much fewer or possibly no interference among sectors or cells.
