Abstract
In some implementations, a base station may provide a first continuous wave signal during a first period of time. The base station may receive, from a first device, a first response signal based on providing the first continuous wave signal. The base station may provide, to the first device, a second continuous wave signal during a second period of time subsequent to the first period of time, wherein the second continuous wave signal is provided based on receiving the first response. The base station may receive, from the first device, a second response signal based on providing the second continuous wave, wherein the second response signal includes device data obtained by the first device.
