Broadband Wireless Access (BWA) Implementation in NGN Network

Abstract

This paper treats BWA (Broadband Wireless Access) implementation in TK (Telecom of Kosova) NGN network in its efforts to keep the leading position in Kosovapsilas competitive telecommunication market. At the beginning, the architecture of TK NGN network with its corresponding elements is described. Such standard-based, open architecture core network enables the integration of Voice and Multimedia services on a single network infrastructure. Along with first and second phase of core network implementation, TK has analyzed the technical and commercial feasibility of implementation of Broadband Wireless Access as a fastest way to satisfy the growing demands for broadband and voice services in un served and rural areas. The choice of IEEE 802.16, commonly known as WiMAX, proved to be one of the best solutions for that purpose. At the end the implementation of WiMAX in TK NGN is presented showing all advantages of the chosen solution such as high bandwidth, adaptive modulation and coding, fits in of all IP architecture, QoS, security, support of different duplex techniques, etc.
