Basic Review Of Wireless Networks

Abstract: With the arrival of wireless technology the human efforts for accessing data at various locations has reduced by replacing wired infrastructure with wireless infrastructure and also providing access to devices having mobility. In the past, some believed wired networks were faster and more secure than wireless networks. But continual enhancements in wireless networking standards and technologies have eroded those speed and security differences. Since bandwidth has to be constrained, some of the key challenges in wireless networks are Signal fading, mobility, data rate enhancements, minimizing size and cost, user security and (Quality of service) QoS. This paper is intended to provide the reader with an overview of the Wireless networking and Challenges in wireless networks.
