Disclosed are an augmented reality method and device for simulating a wireless signal. The method includes: capturing an environment, and forming a three-dimensional virtual representation of the environment; determining a parameter related to a virtual wireless device, the virtual wireless device being a virtual wireless signal source or a reflector; positioning the virtual wireless device in the environment, and simulating virtual wireless signal coverage in the three-dimensional virtual representation of the environment according to the positioning, the parameter, and the three-dimensional virtual representation of the environment; and adding, to the environment, a marker representing the virtual wireless signal coverage to serve as an augmented reality image for display. A wireless signal emission is simulated in combination with an augmented reality technology, so that a user having no professional knowledge of a wireless technology can accurately and quickly estimate behaviors of a wireless system at each position of a desired space.

Distributed antenna systems provide location information for client devices communicating with remote antenna units. The location information can be used to determine the location of the client devices relative to the remote antenna unit(s) with which the client devices are communicating. A location processing unit (LPU) includes a control system configured to receive uplink radio frequency (RF) signals communicated by client devices and determines the signal strengths of the uplink RF signals. The control system also determines which antenna unit is receiving uplink RF signals from the device having the greatest signal strength.

Path-loss measurements are determined for a test client device moving along a path in a field test environment in which field Wi-Fi mesh network nodes are distributed. The path-loss measurements are reproduced in a field-to-lab test environment that includes a test client device disposed in an electromagnetically-isolated chamber and field test Wi-Fi mesh network nodes disposed in respective electromagnetically-isolated chambers. The test client device and the field test Wi-Fi mesh network nodes are in wired or wireless communication with each other via signal lines. A programmable attenuator is electrically coupled to each signal line. The attenuation of each programmable attenuator is varied to reproduce the path-loss measurements from the field test environment. Path-loss measurements at the location of each field Wi-Fi mesh network node are also reproduced with the programmable attenuators to reproduce the field Wi-Fi mesh network node configuration.
