Notice of TV reception countermeasures by the 700MHz Usage Promotion Association

Last Updated March 16, 2020

From around June 2018, each mobile phone operator has started using a new radio wave (700MHz band) at any time in Yokohama city.
As a result, some TV images may be affected.
The 700MHz Usage Promotion Association (established by NTT DOCOMO, KDDI Corporation, Okinawa Cellular Telephone Corporation, and SoftBank Corp.) has implemented construction to prevent this effect, and the cost of the construction is 700MHz. It will be borne by the Promotion Association.
In addition, construction workers will not be charged at all.
