Smart Antennas to Mobile Network Systems
H.B. Bhadka, Chintan Shah · 2008
This paper focuses on the interaction and integration of several critical components of a mobile communication network using smart-antenna systems. Cellular telephone systems are popular worldwide, and the number of users continues to rise rapidly. This has resulted in pressure on the existing cellular network and a drive to develop a more efficient cellular network based on the current spectrum allocations. Research has focused on the use of smart antenna technologies in which identical frequencies can be used in the same cell, increasing the maximum number of users in the cell without allocation of additional radio frequency bands. This paper examines one approach to smart antennas, particular applications to cellular telephone technology. Smart or adaptive antenna arrays can improve the performance of wireless communication systems. In this paper, basic terms such as coverage and capacity are defined. An overview of strategies for achieving coverage, capacity, and other improvements is presented, and relevant literature is discussed.
