Abstract
A testing system comprises an emulator having a simulated radio channel for communicating therethrough with the electronic device. The testing system comprises a plurality of antenna elements coupled to an emulator which forms a beam of a signal of a path of a simulated radio channel with at least two antenna elements of the plurality of antenna elements in an anechoic chamber.
Claims25
A method of communicating with an electronic device under test through a simulated radio channel of an emulator, the method comprising:
- forming a single beam of a single signal of a single path of a single simulated radio channel a using plurality of antenna elements coupled to an emulator in an anechoic chamber, the emulator comprising a plurality of delay elements coupled to a same one of the plurality of antenna elements, wherein power of a simulated cluster is divided between two of the plurality of antenna elements on the basis of antenna angles θk and a cluster angle φn.
A testing system, the testing system comprising:
- an emulator having a simulated radio channel for communicating therethrough with an electronic device;
- and
- a plurality of antenna elements couplable to the emulator, the emulator comprising a plurality of delay elements coupled to a same one of the plurality of antenna elements;
- the emulator being configured to form a single beam of a single signal of a sine path of a single simulated radio channel using at least two antenna elements of the plurality of antenna elements in an anechoic chamber, wherein power of a simulated cluster is divided between two of the plurality of antenna elements on the basis of antenna angles θk and a cluster angle φn.
A non-transitory computer-readable medium storing instructions that, when executed by a processing device, perform a computer process to communicate with an electronic device under test through a simulated radio channel of an emulator, wherein the process comprises:
- forming a single beam of a single signal of a single path of a single simulated radio channel using a plurality of antenna elements coupled to an emulator in an anechoic chamber, the emulator comprising a plurality of delay elements coupled to a same one of the plurality of antenna elements, wherein power of a simulated cluster is divided between two of the plurality of antenna elements on the basis of antenna angles θk and a cluster angle φn.
