In fact, due to their lower frequency, at similar RF exposure levels, the body absorbs up to five times more of the signal from FM radio and television than from base stations.

事实上，由于频率较低，在射频接触水平相同的情况下，人体从调频收音机和电视吸收的信号比从基台吸收的信号要多四倍。

This is lower or comparable to RF exposures from radio or television broadcast transmitters.

这低于或相当于无线电或电视广播发射机造成的射频接触。

The concerns stem from the emissions of radio frequency (RF) radiation by both the handsets and the base stations that transmit and receive the signals.

TD-LTE is the 4G standard developed for use across China, and it is now being adopted by operators across the globe. lightRadio Metro Radio houses two lightRadio cubes, fully integrated with a directional antennae, allowing it to provide the coverage normally associated with a much bulkier, heavier remote radio unit linked to an external antenna via an RF coaxial cable.
