A Robust Analysis of Dual-Band Wireless LAN (4G-WLAN) for Effective Internet Access: A Review Paper

Abstract

This paper presents the findings of a comprehensive study of dual-band WLAN for internet access. It gives an exposition of the architecture of the 4G-WLAN routers which is a more advanced and the latest technology that uses Adaptive Modulation and Coding (AMC) to dynamically react to channel fluctuations while maintaining bit-error rate targets of the transmission. It also x-rays the part played by the internet service providers (ISP), the access providers (i.e. Dial-up, DSL, Satellite and fibre optics) which are responsible for high data throughput and cost of connection. This paper also discusses the IP addressing methods of the connected devices (i.e. BOOTP and DHCP) which depict the Transmission Control Protocol/Internet Protocol (TCP/IP) of the network.  The system clearly provides added convenience of Internet access and the extent of mobility the wireless routers can bring to computer networks and users. This technology provides a platform for future expansion.
