Miller has written more than 100 best-selling books over the past two decades. Jun 30, 2012 · INTRODUCTION Wireless networks have been a crucial part of communication in the last few decades and a truly revolutionary paradigm shift, enabling multimedia communications between people and Introduction to Wi-Fi (802. For valuable Introduction to Wi-Fi (802. 11 specification (ISO/IEC 8802-11) is an international standard describing the characteristics of a wireless local area network (WLAN). Introduction to Wireless Communications and Networks Tongtong Li Dept. Wireless networking is an extension of computer networks into the RF (radio frequency) world. They send and receive on the same channel, so only one device may transmit at any time. A properly designed WLAN for a building pro-vides mobile access for a user from virtually any location in the building. The purpose of this section is to introduce basic wireless physics and explain channel assignments so you can begin planning for a WLAN deployment. Introduction A wireless network enables people to communicate and access applications and information without wires. 11 or WiFi) Introduction to Wi-Fi (802. This chapter describes the standards and specifications that control wireless networks and explains how data moves through the network from one computer to another. It describes and explains what the different wireless technologies are, their main features, security issues, advantages, disadvantages and use E=m·c2 Wireless networks are networks that use radio waves to connect devices, without the necessity of using cables of any kind.
