White Space - Japan Implementation
What is White Space?
Full power analog television broadcasts, which operated between the 54MHz and 806MHz (54-72,76-88,174-216,470-608,and 614-806) television frequencies (Channels 2-69), ceased operating on June 12, 2009 per a United States digital switchover mandate.
At that time, full power TV stations were required to switch to digital transmission and operate only between 54-698MHz. This is also the timetable that the white space coalition has set to begin offering wireless broadband services to consumers. The delay allows time for the United States Federal Communications Commission(FCC) to test the technology and make sure that it does not interfere with existing |television broadcasts. Similar technologies could be used worldwide as much of the core technology is already in place.
White Space in Japan?
Last July 25 2011, Japan ended a 58-year era of analog television broadcast becoming the first Asian nation to complete the transition to digital transmission. Now, same in the US there are unused frequencies that can be utilized for broadband in Rurual areas where High Speed internet is not available.
I'm currently one of the researchers for the White Space Japan working group and have to familiarized myself with technologies such as IEEE802.11af, IEEE802.22, 1900.4 and IEEE802.19.1. The technologies used are some what different from the RFC's (RFC3611 and other SIP related RFC's) for creating mobile and web application. This time around it's the Physical and Data Link Layer's of OSI reference model, something I'm not really familiar. However, I'm quite surprised that I find it really interesting specially surrounded by brilliant minds and talked about data communications, hardware, IEEE papers etc. Not to mention we conduct the meeting in Japanese!
