Instead, the service USES an ATSC broadcasting system to beam signals directly from the station to the mobile devices themselves.

这种服务采用了高级电视系统委员会(atsc)的广播系统直接向手机发射信号。

The satellite would then convert the energy into radio waves and beam them down to a receiving station on Earth.

卫星将空间太阳能产生的电能转化成无线电波，传送到地面接收站。

The station will generate 1 gigawatt of power from sunlight and beam the energy down to a receiving station where it can be used to power almost 300, 000 homes.

该电站将从太阳光产生10亿瓦特的电量，然后通过光的方式传送到地面接收站，可供30万家庭使用。

Given the risks of aiming such a powerful beam of high-intensity radiation at an Earth ground station, as well as the cost of building billions of dollars in infrastructure to collect the energy in space, the efficiencies you can get from terrestrial solar power seem a safer bet--at least for now.

During my tour, he also showed how that same wall can be used to beam in 2D or 3D video from the Web, including the International Space Station.
