Beschreibung
Zusammenfassung:	A communication device includes a directional antenna, and a control circuit. The directional antenna has a directional radiation pattern for directing greater power of a transmitted signal in a specific direction. The control circuit is coupled to the directional antenna and determines an angle and a distance to another device. Based on the determined distance and angle to the another device, the control circuit selects a security level from a plurality of security levels for communication between the device and the another device. In another embodiment, a method for transmitting data between the first and second devices is provided.
