Testing method and arrangement

A method for testing cellular connections, comprising:

• obtaining a three-dimensional model of a given environment;
• obtaining ray tracing calculations describing propagation of radio frequency signals in the given environment;
• determining location of one or more devices in the given environment;
• determining, utilising the ray tracing calculations, radio frequency signal properties of the one or more devices communicating with the device under test;
• transmitting control information to a radio frequency controller for updating the connections between the one or more devices and a set of antenna elements to match with the determined properties;
• obtaining information regarding the location of the one or more devices and regarding propagation environment of the one or more devices;
• and
• updating the radio frequency signal properties of the one or more devices when the location or the propagation environment changes.

An apparatus comprising:

• at least one processor;
• and
• at least one non-transitory memory storing instructions that, when executed with the at least one processor, cause the apparatus to:
• determine location of one or more devices in a given environment;
• determine, utilizing ray tracing calculations, radio frequency signal properties regarding a communication between the one or more devices and a device under test;
• transmit control information to a radio frequency controller, where the control information is configured for updating connections between the one or more devices and a set of antenna elements at least partially based upon the determined radio frequency signal properties;
• determine update information for updating the radio frequency signal properties of the one or more devices, where the determined update information is related to at least one of:
• the location of the one or more devices, or propagation environment of the one or more devices;
• and
• update the radio frequency signal properties of the one or more devices based upon the determined update information including changes to the location or the propagation environment.
