DWW Announces Availability of 868/915 MHz solution. First
Ultra Low Power Wireless PSSS-IEEE802.15.4-2006 platform now available.
About DWW
DWW is a leading provider of digital wireless technology
reference designs based on PSSS/PHY (Parallel Sequence Spread
Spectrum/Physical Layer) that facilitates the manufacture of
ultra low power digital wireless communications IC (integrates
circuit) solutions for use within various market segments, e.g.,
building automation, home control, and audio & video consumer
applications. The product portfolio includes the IP
(Intellectual Property)designs as well as SoC (System on Chip)
and RF (Radio Frequency) design support.
DWW offers platforms and single chip solutions based on the
leading edge digital wireless technology PSSS which provides
highest spectrum efficiency in a limited frequency band - like
the Sub 1 GHz bands 868 and 915 MHz. It can improve the data
rate of an existing wireless IC chip (WPAN or WLAN) by a factor
of up to 10.
Additional Information about the
PSSS/PHY Solution
Today's 2.4 GHz wireless low power IC solutions have the
advantage of a worldwide regulated unlicensed band with a wide
bandwidth of 80 MHz. However, due to the limited radio
propagation of the 2.4 GHz frequency band and the interference
with Bluetooth and WLAN, coverage/range and Quality of Service
(QoS) have become a major issue for low power 2.4 GHz wireless
applications. For example, a typical wireless sensor device
operation in the 2.4 GHz band, which is installed near by a WLAN
access point (for data or voice streaming), would have
significant interference problems because of the much higher
power output of the WLAN system. This limitation has motivated
the OEMs to work on the improvement of the Sub 1 GHz PHY and MAC
performance.
With the introduction of the first worldwide available PSSS/PHY
design solution with up to 1 Mbps in the Sub 1 GHz band, OEMs
will be able to implement and test wireless IC solutions in
their applications, like building automation or industrial
control, without having the problems of interference from
Bluetooth and WLAN. In addition, much better radio propagation
of the Sub 1 GHz solution provides a 2-3 times better coverage
compared to 2.4 GHz. On the other hand, a Sub 1 GHz solution
could be operated with reduced power (out), but still have the
same coverage as a 2.4 GHz solution. This would increase the
battery lifetime of the device dramatically.
The PSSS/PHY wireless solution is based on a digital base band
coding technology that can be combined with various wireless
front-ends. Therefore IC manufacturers and OEMs are able to
improve the performance of their wireless IC dramatically and
still use their existing front-end and their protocol-stack of
their current IC design.
First samples of the PSSS based FPGA IEEE802.15.4-2006 Platform are available. This
module is the first step of a whole product range for various
wireless applications. A final step will be a low-cost highly
integrated single IC. DWW will offer modules based on that IC
for customized solutions.
