16 Annual Report 2014
RESEARCH AND DEVELOPMENT
Aiming to Improve the Business Value through
Development of Advanced Technology
The OKI Group actively develops cutting-edge technologies with the aim of contributing to building
“a safe, secure and comfortable society,” as an important theme for R&D. We designate the important
areas of technology for “a safe, secure and comfortable society” as “sensing,” “smart network,” and
“data mining.” We are further advancing the integration of OKI’s traditional strengths of media processing
technologies and optical broadband technologies with OKI’s ability to build systems.
Furthermore, we are pouring effort into innovative development that will connect the fruits of research
and development with new business value, aiming for the creation of new businesses.
Research and Development for OKI’s Safe, Secure and Comfortable Society Vision
The IT foundation for a safe, secure and comfortable society is formed by organically connecting the tech-
nologies of “sensing,” “smart network,” and “data mining.” Our efforts in these technological areas include
the following:
Sensing
OKI has newly developed radio sensing technology, whereby people’s activities and contexts can be detected
with high sensitivity from fl uctuations in radio waves. When combined with awareness technology, such vital
changes as respiratory rate can even be recognized. With the arrival of the unprecedented aging society, this
technology, together with image-sensing technologies, will contribute to the provision of safety and security.
Smart Network
OKI was the fi rst in the world to develop a 920 MHz bandwidth wireless multi-hop network technology
that can accommodate large-scale as well as small-scale systems, and offers enhanced effi ciency in power
consumption. This enables various sensors and equipment to be connected to networks, regardless of the
environment. This technology is expected to be used in combination with data mining technology, and we
envision its utilization in energy-saving applications at smart offi ces as well as in the disaster recovery fi eld
for remotely surveying the damage from earthquake, for example.
Data Mining
OKI is developing data mining technology to fi nd and utilize hidden “meaningful information” from among
an expansive environment of diversifi ed information and information on people’s activities conveyed via net-
works after obtained from sensing.

Research and Development Leveraging OKI’s Strengths
OKI has strengths traditionally in media processing technologies for audio and video and optical broadband
technologies, and is able to compete on a global level in these areas.
Aiming for Audio and Video Technologies that Provide Greater Comfort
Amid the rapid proliferation of smartphones, OKI is working to develop audio and video technologies that
provide comfort, such as voice processing technologies that achieve clarity in reproduction even in noisy
environments and video coding technologies that can operate even on devices with limited processing ca-
pabilities. Furthermore, we are also working to develop digital signage and other media processing systems
that can integrate these technologies.
Aiming for Further Development of Broadband Networks
In order to realize further improvements in energy conservation, OKI is developing new optical broadband
technology for next-generation optical access networks to realize virtual networks with more effi cient band-
width utilization.
Development of Basic Technologies for the Future
The accumulation of technologies that we develop will become the foundation that supports OKI’s future
businesses. In particular, OKI is researching usability technologies, quantum cryptography technologies,
and recognition technologies. Usability technologies are indispensable to terminal equipment that we have
many years’ research experiences. Quantum cryptography technologies will enable the realization of inde-
cipherable encoding, when everything in society becomes interconnected and security turns to be more
important. Recognition technologies, also, is necessary to replicate human intellectual functions.
