Turn your iPhone or iPad into the hub of a distributed sensor network with the help of an Arduino microcontroller. With this concise guide, you ll learn how to connect an external sensor to an iOS device and have them talk to each other through Arduino. You ll also build an iOS application that will parse the sensor values it receives and plot the resulting measurements, all in real-time.

iOS processes data from its own onboard sensors, and now you can extend its reach with this simple, low-cost project. If you're an Objective-C programmer who likes to experiment, this book explains...

Wireless has finally come of age. With a significant jump in throughput over previous standards, 802.11n is the first wireless technology that doesn t trade speed for mobility, and users have stormed onto wireless networks with a passion. In this concise guide, Matthew Gast chair of the IEEE group that produced revision 802.11-2012 shows you why wireless has become the default method of connecting to a network, and provides technical details you need to plan, design, and deploy 802.11n today.

Building a network for the multitude of new devices is now a strategic decision for network...

The next frontier for wireless LANs is 802.11ac, a standard that increases throughput beyond one gigabit per second. This concise guide provides in-depth information to help you plan for 802.11ac, with technical details on design, network operations, deployment, and monitoring.

Author Matthew Gast--an industry expert who led the development of 802.11-2012 and security task groups at the Wi-Fi Alliance--explains how 802.11ac will not only increase the speed of your network, but its capacity as well. Whether you need to serve more clients with your current level of throughput, or serve...

"Telecommunications is usually responsible for a large percentage of the IT infrastructure costs, usually only surpassed by personnel. Therefore identifying savings, even small in terms of percentage in a large corporate network may mean hundreds of thousands of dollars per month."

"The techniques described in this book already helped and continuous helping hundreds of organizations to save millions of dollars with their telecommunications infra-structures."
