Abstract: A method and a communication device for enabling execution of a virtual activity in a physical environment, wherein development of the virtual activity is presented to a user via at least one user interface of a communication device, the method including: determining a trajectory of the communication device; capturing and consolidating sensor data associated with the physical environment and virtual data associated with the virtual activity; generating at least two mutually dependent zones in the physical environment based on the captured and consolidated data and the trajectory of the communication device, and presenting an updated scene of the virtual activity, including at least parts of the zones via at least one of the user interfaces of the communication device.

Abstract: The present invention relates inter alia to a transmitter arrangement (1), in particular for radio communication, comprising at least two antenna elements (31, 32), spaced apart by a defined distance and a differential output amplifier (20) with a first output (21) coupled to a first (31) of the at least two antenna elements (31, 32) and with a second inverted output (22) coupled to a second (32) of the at least two antenna elements (31, 32). A first transmission line element (50) is arranged between at least one of the first and second outputs (21, 22) and the respective one of the at least two antenna elements (31, 32) and is configured such that signals applied to respective input taps (310, 320) of the at least two antenna elements (31, 32) are substantially in-phase with each other.
