| /hardware/interfaces/wifi/1.3/ |
| D | IWifiChip.hal | 57 * This enum represents the different latency modes that can be set through
66 * API to set the wifi latency mode
68 * The latency mode is a hint to the HAL to enable or disable Wi-Fi latency
71 * Wi-Fi latency optimization may trade-off latency against other Wi-Fi
75 * The low latency mode targets applications such as gaming and virtual reality.
