What kind of tests these devices are undergoing?

For Quuppa Tested Device certification, the key requirement is to have a radio that can transmit Quuppa Direction Finding packets (as specified in Quuppa Emulation Specification) at least on one of the Quuppa tracking channels. Once correct packet transmission is confirmed, the device’s positioning performance is being tested in the office environment as well as in the field environment. Finally, we will evaluate the antenna radiation pattern (subject to availability).
