Description
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 covers:
* Laptop wireless Ethernet
card introduction and theory
*Introduction to CompactFlash-to-microcontroller interfacing
* Implementing the laptop wireless Ethernet
card in an embedded environment
In addition, the book includes a CDROM containing all of the code, schematics and programs necessary
to implement embedded 802.11 wireless networking.
Audience
PRIMARY MARKET: Embedded systems engineers and programmers SECONDARY MARKET: Electrical/software engineering students, electronics technicians
working in embedded systems, inhouse training departments of electronics manufacturers, electronics hobbyists
