|・||Takes advantage of the transparency of glass to be unobtrusive and avoid spoiling interior designs or the view from the window.|
|・||Decreases attenuation and reflection of radio waves passing through existing window glass by using a newly-developed Glass Interface Layer*4|
AGC and NTT DOCOMO plan to roll out this product to LTE (the current mainstream) frequency-band base stations from the first half of 2019 onward. The two companies are also considering the development of 5G-compatible products.
*1 Based on research by AGC and NTT DOCOMO.
*2 Base stations that create a small service area within the area of a regular base station, installed mainly in high-traffic areas.
*3 Method for adding functionality, such as energy conservation or soundproofing, to existing glass by attaching a glass product to their interior side
*4 Draws out the typical performance of antennas by mitigating the effects on performance caused by the proximity of glass antennas to existing window glass.
1. Glass Antenna Details
|・||Does not spoil the appearance of streets or neighborhoods due to being a transparent glass antenna installed onto an existing window.|
|・||Installation is carried out inside buildings, eliminating the need for scaffolding or foundation work.|
|・||These glass antennas for small cells provide flexibility for area design due to their ability to be installed almost anywhere and their beam-forming technology.|
|Dimensions||700 mm × 210 mm|
Base Station Specifications
|Frequency||3.5GHz band (BAND42)|
|Downlink modulation method||256QAM|
|AGC||・Develop and produce the glass antenna, and establish its installation method.
・Considering the effect of glass antennas on the existing window glass.
|DOCOMO||・Consider antenna characteristics from the viewpoint of radio wave protection and securing the communication area.
・Ensure practicability of securing the communication area through verification testing.
