Wireless networking is poised to have a massive impact on communications, and the 802.11 standard is to wireless networking what Ethernet is to wired networking. There are already over 50 million devices using the dominant IEEE 802.11 (essentially wireless Ethernet) standard, with astronomical growth predicted over the next 10 years. New applications are emerging every day, with wireless capability being embedded in everything from electric meters to hospital patient tracking systems to security devices.This practical reference guides readers through the wireless technology forest, giving them the knowledge, the hardware and the software necessary to design a wireless embedded device rapidly, inexpensively, and effectively. Using off-the-shelf microcontrollers from Microchip and Atmel, the author provides step-by-step instructions for designing the hardware and firmware for a fully operational wireless networking device. The book gives a thorough introduction to 802.11 technology and puts it into perspective against the other wireless standard options. Just enough theory and mathematics is provided to give the depth of understanding needed for practical design work.The book thoroughly * Laptop wireless Ethernet card introduction and theory*Introduction to CompactFlash-to-microcontroller interfacing* Implementing the laptop wireless Ethernet card in an embedded environment

Sophisticated networking and communications capabilities, once exclusive to mainframes and PCs, are now essential for smaller embedded microcontrollers. However, the relevant documentation and design information is often scattered and hard to locate. In this practical guide, embedded designer Fred Eady consolidates the necessary design background and details, demonstrating how to leverage affordable microcontrollers for robust communications and networking applications like local area networks and embedded internet. Through working code examples and schematics, Eady introduces the basics using two popular microcontroller families, PIC and Atmel. The book includes detailed design examples covering topics such as RS-232 firmware and hardware, microcontroller USARTs, the I2C bus, Ethernet implementation, embedded internet, and wireless links. Sample source code is provided and thoroughly explained for each application. The accompanying CD-ROM features the example code and a searchable ebook version of the text, facilitating quick comprehension. This indispensable reference compiles hard-to-find design information and offers step-by-step guidance for creating powerful networking applications, including fully functional microcontroller hardware and firmware examples.
