华为和中兴率先研制出一种叫“远程射频头”的技术。

Huawei and ZTE led the way in something called "remote radio-head" technology.

不过射频识别标签和无线传感器，另外就此而言还有数码摄像头(得益于手机的广泛普及，后者是迄今为止部署范围最广的传感器)，只不过反映了问题的一面。

Yet RFID tags, wireless sensors and, for that matter, digital cameras (so far the most widely deployed sensor thanks to the popularity of mobile phones) are only half the story.

往上流经支撑结构的射频电流会将不期望的偏压施加在支撑结构上，也会因此降低流至喷洒头的射频电流。

The RF current that flows up the support structure puts an unwanted bias on the support structure and also contributes to reduction of the RF current flowing to the showerhead.
