Use powerline communication and Bluetooth for a smart home Design How-To 8/13/2010 4 comments Here's a case for the use of a mixed system, whereby existing electrical wiring and outlets are used as the medium for data communication within the home. The user interacts with the system wirelessly via a Bluetooth-enabled device, and an adapter serves as the bridge between the two networking technologies.
An Intro to Networking - Part IV Design How-To 8/12/2010 Post a comment Networking is a new concept for many embedded engineers. The goal of this book, therefore, is to provide a bridge that spans from basic concepts to how to add networking functionality to an embedded design. This chapter provides a quick introduction to networking protocols and then moves rapidly to a discussion on TCP/IP over Ethernet, today's preferred network technology combo with the widest usage in terms of the number of devices and applications. Here is the final segment of Chapter 2.
