WIRELESS NETWORK

Wireless networks and wireless communications technology have the potential to make universal Internet use a reality, which will clearly lead to global connectivity, roaming, and ubiquitous communications. Given the astonishing increase in the number of Internet users (doubling every 90 days), this course aims to examine the relationship between the Internet and wireless networks. To that end, the emerging third generation (3G) wireless standards and how they accommodate data communications in addition to voice will be highlighted. While the emphasis will be on the networking issues and aspects of wireless communication networks, the relevant physical issues will briefly be reviewed as well.
