摘要： An electronic device has multiple transmitters to transmit multiple signals. The electronic device also has a receiver to receive a signal. Moreover, the electronic device has a memory to store instructions and a processor to execute the instructions. The instructions cause the processor to send a test transmission signal from a transmitter of the multiple of transmitters, receive the test transmission signal at the receiver, and determine a gain of the test transmission signal. In response to determining that the gain is within a threshold range of an initial gain, the instructions cause the processor to send an indication that the receiver is operating as expected.

摘要： Wireless network interfaces that are capable of transmitting and/or receiving beamformed radiofrequency (RF) signals may be assisted by the use of codebooks. Electronic devices with memory to store a database of codebooks may be used to increase the number of entries available for operation. The database of codebooks may employ environmental parameters to improve efficiency of the wireless network interface. Methods for calibration of electronic devices and/or adjustment and selection of codebooks based on the parameters are also described. The calibration may employ a testing chamber that measure powers at in a limited number of angles.

摘要： The disclosed embodiments provide a system that tests wireless devices. The system includes a signal generator that generates a downlink signal. The system also includes a management apparatus that tests a first wireless device using the downlink signal. During testing of the downlink signal, the management apparatus configures a second wireless device to listen to the downlink signal and save a set of tuning circuit states for synchronizing to the downlink signal. The management apparatus may then configure the second wireless device to load the saved tuning circuit states to expedite synchronization with the downlink signal during subsequent testing of the second wireless device.
