EMAIL INTERVIEW – Mark Walters and Ken Sinclair
Mark Walters, Chairman, Z-Wave Alliance
Mark has over 20 years experience in all aspects of electronic product solutions. He has a background in product design and development having served as chief engineer for a high-end audio company, a vehicular sensor and controls company and a manufacture of premise wiring solutions. Additionally, he is a seasoned veteran in the building controls market including positions held with Alerton, Encelium Technologies and Leviton Manufacturing. Currently Mark serves as the Chairman of the Z-Wave Alliance, an open consortium of leading global companies dedicated to establishing Z-Wave as the standard in wireless controls. Mark holds bachelor’s degrees in Biology and Chemistry from the University of California at Santa Cruz and a MBA from City University, Seattle.
Technology for Control and Monitoring
Sinclair: Why is Z-Wave being selected by more and more companies, we just heard about the 600th certified product, but it isn’t well known in the commercial world, why?
beginning Z-Wave was only used in residential applications, that
is where we got our start and where most of our manufacturers do the
bulk of their business. What we see today are more Z-Wave
products being designed specifically for commercial applications such
as thermostats for mini-split systems, card key scanners and shade
motor and control system for large spaces. The 600th product, a
Whole House Power Monitor for two phase power systems, could just as
easily be used in a light commercial power monitoring
application. Maybe I want to sub-meter a large piece of 2-phase
equipment and have its demand and consumption delivered to my desk or
control center. How much energy is that drying oven, pick
and place machine or reflow oven really using. With Z-Wave
products this is a few hundred dollars, few hours long
than the obvious reasons for Wireless, ease
of installation, placement flexibility and remote operation, what
should we know about Z-Wave?
most important in wireless communications is what is known as
reliable communications. In techno speak, reliable communications
means every message is checked for transmission accuracy and
acknowledged by the receiver back to the sender. Z-Wave uses
reliable communications and automatically resends the message if it
isn’t acknowledged by the receiver. This closed loop communication is
critical to many commercial control applications. Another concern
is security, can the network be hacked? Z-Wave has stood the test
of many high security applications including residential and
hospitality parameters and lock control. Z-Wave uses the
same AES128 bit security that is used for Internet banking
key applications are you seeing solved with Wireless in general and
Z-Wave in particular?
Walters: Some of the key commercial applications for wireless technology are:
does the recent ratification of
and PHY by the ITU-T as the G.9959 standard effect the
future of Z-Wave?
