Abstract

Embodiments include systems and methods for simulating a multipath environment for testing a device. In one embodiment, a plurality of antennas are placed around a device under test in an anechoic chamber. Each of a plurality of the antennas is connected to a path of a variable path simulator capable of generating multiple paths between the antennas and external wireless communication test equipment. The variable path simulator introduces a delay spread into each path. In this way, a multipath environment is simulated with signals appearing to arrive from different angles and different distances. Each of a plurality of antennas may be adapted to produce substantially plane waves at the device under test.
