OSAKA, Japan -- May 7, 2013

Panasonic Corporation today announced that it has developed a new multi-band
wireless communication technology that enables low powered stable
communication through simple wireless connections between devices of different
standards. Devices equipped with this technology will be able to support all
the frequency bands of wireless sensor networks and realize energy savings of
30% of the power of conventional single band wireless blocks. These
technologies will accelerate the spread of "M2M (Machine to Machine) Sensor
Networks" that support cloud-based data exchange without human intervention.

The development combines all of the tuning circuits which had previously been
necessary for each frequency band, allowing for a stable connection to the
network regardless of the location and the wireless standard of the device. In
addition, by detecting the radio frequency component directly, a reduction in
the size of the chip and its power consumption has also been achieved. In
applications where the power supply can be problematic, sensor network radio
powered by batteries has become possible. Through this technology, connecting
devices and equipment will become easier, accelerating the development of a
new business model for cloud applications.

The developed technology has the following features.

  *Supports all frequency bands (400MHz, 900MHz, 1.2GH and 2.4GHz) for
    IEEE802.15.4x sensor network radio regulations.
  *The surface area of the chip which supports multi band is 12% smaller than
    a conventional single band chip.
  *More effective demodulation process introduced to reduce power
    consumption. The working time is expected to be more than 20 years under
    typical wireless network operating conditions in the field of smart meters
    and HEMS applications, with data transmission every 30 seconds with a
    1200mAh battery.

This development is based on the following new technologies.

1.Multi-band technology makes the removal of some inductors on receivers and
    filters on transmitters that were previously necessary for each frequency
    band possible through digital assist analog circuits.
2.Demodulator with direct frequency detection scheme for reducing the
    circuit size and power consumption of the receiver.

Panasonic holds 25 Japanese patents and 14 overseas patents, including pending
applications, for this development.

This result was supported in part by the "R&D of radio communication
infrastructure technology using multiband/multimode compatible sensors" of The
Ministry of Internal Affairs and Communications, Japan. A part of this
technology will be presented at Wireless M2M Expo 2013 at Tokyo Big Sight,
Japan on May 8-10.
