Android device you're using for testing.</p> <h2 id="physical-environment" data-text="Physical environment" tabindex="-1">Physical environment</h2> <h3 id="ble-beacons" data-text="Bluetooth LE beacons" tabindex="-1">Bluetooth LE beacons</h3> <p>If the device under test (DUT) supports Bluetooth LE, place at least three Bluetooth LE beacons within 5 meters of the DUT for Bluetooth LE scan testing. Those beacons don't need to be configured or emit anything specific, and can be any kind, including iBeacon, Eddystone, or even devices simulating BLE beacons.</p> <h3 id="uwb" data-text="Ultra-wideband" tabindex="-1">Ultra-wideband</h3> <p>If the DUT supports ultra-wideband (UWB), another device supporting UWB must be positioned close enough and oriented so as not to have an antennae and radio dead zone. For the distance accuracy tests, there are specific positioning and orientation needs. For setup details, see <a href="/docs/core/connect/presence-requirements#uwb-requirements">UWB requirements</a>. The UWB test must be run manually, specifying on the command line which two devices are one meter apart. For details on sharding which is required for this test, see <a href="/docs/core/tests/tradefed/architecture/advanced/sharding#local_sharding">Local sharding</a>.</p> <h3 id="cameras" data-text="Cameras" tabindex="-1">Cameras</h3> <p>When running camera CTS, use normal lighting conditions with a test pattern chart (such as a checkerboard pattern). Place the test pattern chart according to the DUT's minimum focus distance to ensure that it isn't too close to the lens.</p> <p>Point the camera sensors to a scene with sufficient lighting to allow the sensors under test to reach and remain at the maximum configured target frames per second (FPS) as specified in <a href="https://developer.android.com/reference/android/hardware/camera2/CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE"><code translate="no" dir="ltr">CONTROL_AE_TARGET_FPS_RANGE</code></a>. This applies to all camera sensors reported by <a href="https://developer.android.com/reference/android/hardware/camera2/CameraManager#getCameraIdList()"><code translate="no" dir="ltr">getCameraIdList</code></a> as the test iterates over the listed devices and measures performance individually.</p> <p>If the DUT supports external cameras, such as USB webcams, plug in an external camera when running CTS. Otherwise, the CTS tests fail.</p> <h3 id="gps-gnss" data-text="GPS/GNSS" tabindex="-1">GPS/GNSS</h3> <p>If the DUT supports the global positioning system/global navigation satellite system (GPS/GNSS) feature, provide a GPS/GNSS signal to the DUT at a suitable signal level for reception and GPS location calculation. The GPS portion must be compliant with ICD-GPS-200C. Otherwise, the GPS/GNSS signal can be of any kind, including a satellite simulator or a GPS/GNSS repeater of outdoor signals, or you can place the DUT close enough to a window such that it can directly receive enough GPS/GNSS signal.</p> <aside class="caution"><strong>Caution:</strong><span> For the GPS testing, the internet connection setup must not block connections to <code translate="no" dir="ltr">supl.google.com</code> port 7276. This port downloads GPS assistance data for testing position calculation on the local device.</span></aside> <h3 id="wifi-and-ipv6" data-text="Wi-Fi and IPv6" tabindex="-1">Wi-Fi and IPv6</h3> <p>CTS tests require a Wi-Fi network that supports IPv4 and IPv6, has an internet connection with working DNS for IPv4 and IPv6, supports IP multicast, and can treat the DUT as an isolated client. An <em>isolated client</em> is a configuration where the DUT doesn't have visibility to the broadcast/multinetwork messages on that subnetwork. This occurs with a Wi-Fi access point (AP) configuration or by running the DUT on an isolated subnetwork without other devices being connected.</p> <p>If you don't have access to a native IPv6 network, an IPv6 carrier network, or a VPN to pass some tests depending on IPv6, you can use a Wi-Fi access point and an IPv6 tunnel.</p> <p>To pass CTS, the DUT needs the <code translate="no" dir="ltr">UP</code>, <code translate="no" dir="ltr">BROADCAST</code>, and <code translate="no" dir="ltr">MULTICAST</code> flags set on the Wi-Fi interface. The Wi-Fi interface needs IPv4 and IPv6 addresses assigned. Check the Wi-Fi interface properties with <code translate="no" dir="ltr">adb shell ifconfig</code>.</p> <p>For devices that support <a href="/docs/core/connect/wifi-sta-sta-concurrency">Wi-Fi STA/STA Concurrency</a>, multiple Wi-Fi networks (at least 2) are required. To pass CTS, the Wi-Fi networks must run on different bands with different SSIDs or on the same SSID with different BSSIDs.</p> <h3 id="wifi-rtt" data-text="Wi-Fi RTT" tabindex="-1">Wi-Fi RTT</h3> <p>Android includes the <a href="https://developer.android.com/reference/android/net/wifi/rtt/package-summary">Wi-Fi RTT API</a> for a <a href="/docs/core/connect/wifi-rtt">Wi-Fi round trip time (RTT)</a> capability. This allows devices to measure their distance to access points with an accuracy of 1 to 2 meters, significantly increasing indoor location accuracy. Two recommended devices supporting Wi-Fi RTT are <a href="https://store.google.com/us/product/google_wifi_first_gen">Google Wifi</a> and <a href="https://fit-iot.com/web/products/fitlet2/">Compulab's fitlet2 access point</a> (set to 40 MHz bandwidth at 5 GHz).</p> <p>The access points should be powered up, but don't require a network connection. Access points don't need to be next to the testing device but are recommended to be within 40 feet of the DUT. One access point is typically sufficient.</p> <h2 id="desktop-machine" data-text="Desktop machine setup" tabindex="-1">Desktop machine setup</h2> <p><strong>Caution</strong>: CTS supports 64-bit Linux machines. CTS is not supported on Windows OS or MacOS.</p> <h3 id="ffmpeg" data-text="FFMPEG" tabindex="-1">FFMPEG</h3> <p>Install the ffmpeg version 5.1.3 (or later) package on the host machine.</p> <h3 id="host-machine-reqt" data-text="Host machine requirement" tabindex="-1">Host machine requirement</h3> <p>The minimum requirement for the CTS host machine is 32 GiB RAM and 256 GiB disk capacity.
