Mobile WiMAX-based communication network planning in Seribu Island by utilizing existing towers

摘要

An archipelago consisting of number of islands is relying on the broadband wireless technology to facilitate its telecommunication service. Mobile WiMAX (Worldwide Interoperability Mobile Access), as one of the broadband wireless technologies, is proposed to be applied as the network deployment in this paper. The network planning is designed based on cellular communication systems using hexagonal cells model. Five islands located at Seribu Island are being the object of investigation in the communication network planning. By use of a 5MHz bandwidth channel lied at working frequency of 2.5GHz mobile WiMAX, the planning of communication network is designed referring to the WiMAX Forum whitepaper. The cell planning takes a number of cells obtained in compromise between the coverage and the capacity approaches by including the existing tower to suppress the cost of network deployment. Based on the field survey result, the SUI (Stanford University Interim) model is chosen to calculate the cell coverage of terrain B and C. Meanwhile, the capacity demand that consists of shared and telephony bandwidth is obtained from the estimation of users traffic determined from the given demography data. Simulation of the network deployment is carried out using RF planning software following by the analysis of simulation result.
