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.
