Radar technology has been there a long time and is widely used in various fields. In the military, this technology is very familiar because it is widely used in surveillance efforts. Accordingly, recently Nokia has succeeded in developing radar technology to support a variety of homemade devices, future technology being developed by Nokia this, change-capable handsets into the radar device. However, not much need for traditional radar used on the smartphone device.

In one occasion, Nokia has demonstrated this radar technology demonstration yg located in the Nokia Research Center (NRC) Helsinki, Finland some time ago. According to Siemens, this technology uses electromagnetic waves to provide a variety of wireless sensing. The result is a device that can measure the speed and direction of movement of an approaching object.

There are a lot of potential from the existence of this technology, such as motion control theory does not have to stop to control the volume. This radar detection also works when covered with mobile devices. And this is one way to find out how much the radar performance of mobile devices is still in a pocket, purse or other protection.
