NTT DoCoMo to Apply for License to Set Up Outdoor Stations for Wireless Broadband Field Experiment


TOKYO, JAPAN, March 28, 2006 --- NTT DoCoMo, Inc. announced that it applied today to the Ministry of Internal Affairs and Communications for a license to set up experimental outdoor wireless stations to test WiMAX, a new wide-area wireless broadband network technology, based on the IEEE 802.16e standard.

DoCoMo, working in collaboration with other NTT group companies, will conduct the test in the Yoyogi area of Tokyo for about one year using the 2.5GHz frequency band. The test will cover the following subjects:

  • Assess throughput and wireless transmission characteristics according to the distances between a handset and base station, and handset moving speed.
  • Verify the optimal wireless parameters and base station allocations to obtain maximum results.
  • Assess the possibility of interference from existing satellite communication systems, such as WideStar™.
  • Confirm continuous connections during handover within the WiMAX system or between WiMAX and other systems, such as HSDPA.
