Japan uses the 38GHz frequency band to achieve the world's first 4-kilometer altitude 5G communication demonstration

According to news on May 29, SKY Perfect JSAT, NTT DOCOMO, Japan’s National Institute of Information and Communications Technology (NICT) and Panasonic jointly announced yesterday that they have successfully used light aircraft to simulate high-altitude platform stations (HAPS). A verification demonstration of 5G communications was conducted at an altitude of approximately 4 kilometers using the 38 GHz frequency band.

This test used 38 GHz frequency band radio waves to establish a 5G NR air relay backhaul line for the ground 5G network between an aircraft flying at an altitude of about 4 kilometers and three ground stations. It is the first of its kind in this field.

Non-Terrestrial Network (NTN) using HAPS is an effective technology for expanding communication coverage in 5G and 6G. The results of this demonstration It will accelerate the practical application of HAPS network. Attached is an introduction to the companies or organizations participating in the study: SKY Perfect JSAT is a Japanese satellite operator and the only provider in Japan that simultaneously provides multi-channel pay TV broadcasting and satellite communication servicesNTT DOCOMO is Japan Mobile Operator, with more than 89 million users, is one of the major contributors to 3G, 4G and 5G mobile network technologies The National Institute of Information and Communications Technology is Japan’s only national research and development institution specializing in the field of information and communications technology Panasonic was founded in 1918, and its business covers consumer electronics, residential, automotive, industrial, communications and energy fields
