DNP：开发5G反射阵列：扩大毫米波覆盖范围
-避开障碍物并传送无线电波-
大日本印刷 (DNP)：
反射5G通信的毫米波。
我们开发了一种反射阵列，可通过反射扩大覆盖范围。
我们支持使用毫米波的 5G 通信网络的普及。
5G毫米波反射阵列：
5G毫米波，
反映在预期的方向，
避免障碍物。
这种无线电波反射器不同于金属反射器，它像镜子一样简单地反射无线电波。
反射阵列的特点：
特点是特定频率的无线电波可以向任何方向反射。
通过很好地反射无线电波，
到目前为止，5G毫米波很难到达，
无线电波也可以在建筑物之间传送。
可以使用 5G 毫米波扩展高速通信网络。
使用领域：
这种无线电波反射器甚至可以在城市外使用
有许多无线电波屏蔽的工厂，
布局不断变化的展厅，
一个只在该地区发布信息的体育场，
预计将用于游乐设施。

DNP Develops Reflect Array to Expand 5G Coverage Area
DNP Group Tokyo,
August 31, 2021.
Dai Nippon Printing Co., Ltd. has developed a Reflect Array
that flexibly reflects the millimetre waves used in fifth generation (5G) mobile communications systems to expand coverage area.
Compared to general metal reflectors,
the new product is capable of reflecting millimetre waves in a more targeted manner.
As a result,
there are fewer restrictions on installation, making it possible to improve the communications environment in locationswhere radio waves have been difficult to reach, such as those in the shadow of buildings.
In addition,
the new product boasts superior design features allowing it to respond to various installation environment considerations.Background
The 24GHz and above radio waves used in the high-speed large-capacity communications of 5G
are higher frequency milliwaves than those used in 4G, and maintain a larger information capacity.
At the same time,
they are characterized by strong straightness properties and short reach, leading to radio waves being blocked in areassuch as in the shadow of buildings
making it difficult to ensure communication quality.Also, when adding base stations and relay equipment to resolve this issue, new challenges emerge,
such as large costs and the difficulty of securing installation space.
