3. WIRELESS COMMUNICATION
The rapid worldwide growth in cellular telephone subscribers has demonstrated conclusively that wireless communication is a robust, viable voice and data transport mechanism. Many formidable obstacles stand in the way of achieving reliable and very high data communications. The requirements for capacity and speed in the network entail that today’s systems have to be developed further or replaced by new ones. However, the wide-spread success of cellular has led to the development of newer wireless systems and standards for many other type of telecommunication traffic besides mobile voice telephone calls. For example, next generation cellular networks are being designed to facilitate high speed data communications traffic in addition to voice calls. New standards and technologies are being implemented to allow wireless networks to replace fiber optic or copper lines between
fixed points several kilometers apart (fixed wireless access)[3].
