Technical Requirements for Upgrading of Broadband Mobile Wireless Access Systems

1.Background

  After broadband mobile wireless access systems were institutionalized in 2007 in response to increasing needs of users for high-speed wireless Internet access, services have been provided by two nationwide operators and regional operators. The upgrading of technology has advanced since the commencement of providing services for the purpose of improving convenience of users by speed-up of transmission rate, etc. The number of users is over 2 million and it is still increasing.
  On the other hand, the service of 3.9G mobile radio communication system (LTE) which realizes a downstream transmission rate of more than 100Mbps has commenced from December 2010 and the speed-up of mobile communications services is progressing. As for broadband mobile wireless access systems, works for international standardization have been in progress in order to realize high-speed and high-capacity communications same as optical lines.
  In view of these circumstances, the Information and Communications Council has deliberated on further upgrading of broadband mobile wireless access systems and examinations on interference with other systems from September 2011 and the results of deliberation pertaining to “technical requirements for upgrading of broadband mobile wireless access systems” were compiled. On April 25, 2012, a partial report was received from the Information and Communications Council.
 

2.Future plans

  The MIC carry forward the formulation, etc. of technical requirements based on this partial report.
