powered by kinetic energy harvesting and
don’t require batteries (shown).
EnOcean is a long-time player in simple
controls for SSL and other home and commercial automation environments, and
has long championed its own wireless connectivity scheme that has been promulgated by the separate EnOcean Alliance.
We published a detailed feature article on
the advantages of such wireless controls
two years ago ( http://bit.ly/1ONnsYF). As
the article chronicles, quite a few companies have supported the EnOcean
Alliance wireless scheme with
the company EnOcean being
just one such vendor.
Indeed, EnOcean demonstrated its wireless controls
using a frequency band below 1
GHz at Strategies in Light earlier
this year ( http://bit.ly/2squ PRy).
And the company provided an
early look at Bluetooth products.
products have required a very-
low-power approach to wire-
less communications. The act
of a person depressing a switch
has to generate sufficient kinetic energy
for the switch to awaken the integrated
electronics that then transmit a message
to the powered lighting device such as an
LED lamp or luminaire. Many wireless
networks are simply too power hungry for
such battery-free operation. But Bluetooth
was developed for low-power systems such
as location beacons.
Going forward, EnOcean will offer its
EasyFit products in both the sub-1-GHz
models and in Bluetooth versions that
operate in the 2.4-GHz band. In both cases,
the switches and controls can be commissioned using the NFC (near field communication) capability integrated into many
mobile phones and tablets.
Silvair, meanwhile, has been one of the
driving forces behind the development of
Bluetooth Mesh. The company contributed an article on the development last year
( http://bit.ly/1XrFgiG). Silvair has developed a software stack that can be hosted
on microcontroller-based Bluetooth ICs
from a number of leading vendors such as
Texas Instruments. And now EnOcean and
Silvair are partners. ◀
