Cognitive functionality in next generation wireless networks: standardization efforts
Summary (1 min read)
INTRODUCTION
- The question, however, is where to look for the unused spectrum with the myriads of wireless devices employed around the globe and with a status quo in spectrum regulations.
- The first model is dominating the current wireless world, but it is inefficient.
- To some extent, this coordination currently is lacking.
A LOOK AT THE HISTORY OF THE DEVELOPMENT OF OPEN SPECTRUM ACCESS SYSTEMS AND REGULATIONS
- One of the first communication systems using shared radio resources was maritime communication (1910s).
- With the advent of wireless data communication, the Aloha protocol, proposed in 1970, enabled sharing of the radio channels for wireless data communication without using a centralized entity.
- This indirectly gave way to an FCC Rule Part 15 (1985) that described the coexistence procedures for lowpower wireless devices in the industrial, scientific, and medical (ISM) bands.
- The British Cordless Telephone Second Generation Standard (mid 1980s) was another example of a successful and distributed channel management technique.
- SDRs were developed and enabled even greater flexibility in radio access.
CONFORMITY ASSESSMENT, ACCREDITATION, AND CERTIFICATION
- Because the next generation radio deals with SDR and CR devices that are capable of downloading software to reconfigure themselves, it is beneficial to have a look at the existing standardization policies for software certification, accreditation, and so on.
- CABs should first conform to ISO/IEC 17011:2004, which specifies general requirements.
- One important standard to mention in this context is ISO/IEC 9126-(1-4):2001-2004, which is an international standard for the evaluation of software.
- Thus, the standard captures all the necessary tools to evaluate the software used in critical settings.
- The certification that the devices are tamperproof is crucial for wide use of CR devices.
CONCLUSIONS
- The efforts of IEEE SCC41 were introduced.
- An account of the operation of various IEEE SCC41 working groups that are focused on CR was given.
- The operational domain of each of the projects was described in detail.
- As a starting point, the applicability of existing ISO to the CR standardization process with accreditation procedures and certification were introduced.
- It is believed that this article will be helpful for researchers, standards bodies, and organizations working on cognitive radio.
