Prevas: Bluetooth Low Energy
VÄSTERÅS, Sweden --(Business Wire)--
"Expanding our range of ultra-low-power technologies by including
Bluetooth Low Energy in our existing designs is a natural step for us.
Bluetooth has been around since the last millennium, but only now with
version 4.0 of the Bluetooth core specification are we unlocking the
real potential for ultra-low-power designs. This latest update focuses
specifically on minimizing the power consumption in both idle and active
mode, enabling even coin cell battery powered devices to run for many
months without recharging. Besides extending the recharge interval for
rechargeable devices, this offers the possibility to completely abandon
the recharge option in many cases, significantly reducing material cost
and complexity", says Engineering Manager Jakob Koed Prevas A/S.
Bluetooth devices featuring the Low Energy version of the specification
are referred to as either Bluetooth Smart devices (typically sensor
devices) communicating exclusively using the low energy scheme, or
Bluetooth Smart Ready devices capable of both low energy and standard
communication through a dual radio design. A very long and growing list
of Bluetooth Smart Ready devices exist, including most recet
smartphones, tablets and laptops. This means that Bluetooth Smart
devices are capable of communicating with a host of devices right from
product launch, avoiding the typical "the-chicken-or-the-egg" syndrome.
Prevas' experience from ultra-compact custom electronics, used for
instance in intelligent credit cards, goes hand-in-hand with the
technological benefits from industrial standards optimized for real-life
applications. A recent example is meeting the extreme energy saving
requirements of our intelligent powered cards in credit card format
developed for Cardlab. In this application, Bluetooth Low Energy is used
for receiving wide variety of card data including financial and access
control data from a smart phone app.
"Using commercially available System-On-Chip (SOC) solutions is the
optimal approach for most of our designs, as the shortest route to the
target, in turn imposing the lowest risk in the development project.
Several such solutions incorporating Bluetooth Low Energy are available.
For instance, we find that SOCs are even applicable for our
state-of-the-art compact electronics", comments Jakob Koed.
With cutting edge expertise in embedded systems and industrial IT,
Prevas contributes by providing innovative solutions that create growth.
