Title:
操縦可能スポットライトビームを有するセルラーアレイ
Document Type and Number:
Japanese Patent JP6498782
Kind Code:
B2
Abstract:
Cellular array implementations with multiple steerable spotlight beams irradiated from a common aperture are disclosed herein. Such an approach can easily be adapted to suit various geographical population densities and distributions. The array is capable of producing multiple 65-degree cellular coverage beams, which may be used for regular coverage or in MIMO (Multiple Input Multiple Output) mode. The array may also produce multiple steerable beams, or “spotlight” beams. These beams may be relatively narrow and may be steered electronically both in azimuth and elevation directions. By steering the beams in this way, the beams are able to provide cellular services at high-demand “hotspot” regions where high capacity service is required. The spotlight beams may also be used to fill voids or deficiencies caused by regular coverage beams.
