INTRODUCTION TO NETWORKED HOME
MAHBUBUL ALAM, SUDHIR DIXIT, AND RAMJEE PRASAD
Advances in communications technology to seamlessly connect all types of home devices and appliances are driving the vision to create an intelligent home ecosystem.
This would enable control, access, and information sharing among all the devices and thereby a much more enhanced user experience.
The future growth of electronics at home lies in the devices being able to wirelessly communicate among themselves and with one or more universal handheld portable multiradio devices (including other intelligent control points).
Such a control device would be able to control the other wireless-enabled devices in a distributed or centralized manner.
All devices would in the future come with some type of a radio interface built into them. One could potentially conceive the giant intelligent “home system” as being distributed but connected in a modular fashion over a large-area wireless infrastructure.
