SSIA SUMMIT October 2014
Advanced Bridging Technologies Hold
Key to Finally Making Smart Homes a
Reality
Fred Dart – FTDI Chip
Introduction
The employment of technology to monitor and
control basic domestic functions automatically is a
concept that is far from new.
For well over a decade now the possibility of
creating what have become known as ‘smart
homes’ has gained a great deal of media attention
- promising enhanced comfort, improved safety
and higher energy efficiency levels within the
places we inhabit.
Introduction ctd.
Until now though actual takeup has been very
limited.
Reasons for this include –
- High cost of implementation
- Different technologies which don’t talk to each
other
- Low communication speeds give poor response
times ( X10 for example )
- Limited connectivity

Benefits
Finally, low cost wireless communication becomes a possibility.
Mass adoption drives the cost down finally making the
possibility of affordable Smart Homes a reality
Issues
A lack of common standards for devices – inability to link
devices together
Over reliance of mobile phones as the control point
* Too many different apps with no common look and feel
* Lost mobile phones
* Friends and Family unfriendly
No common approach to security for internet connected
devices

• Zigbee enabled light bulbs are arranged in a mesh network.
• Control, i.e. turning on or off, dimming, can be done via
• FT900 + FT800 platform.
• Smart phone.
• Smart phone is connected to the FT900-FT800 platform using Wi-Fi Direct.
• GUI on the smart phone and the touch screen display have the same look-and-feel.
Objectives
• Proof-of-concept for a home automation smart bridge based on the
FT900 + FT800 platform, bridging Wi-Fi to other common wireless
technologies such as Zigbee, 6LoWPAN etc…
• Build the required hardware and software blocks which can be
subsequently implemented in a home automation smart bridge.
