Question

我想测量调制解调器的 rssi 值。是否有 spi 能为 Windows 获得 rssi 值? 我用 Wifi. manager in and roid. 但我找不到 Windows 的 spi 。

Answer 1

使用本地代码是最好的。您需要使用 wlan_ intf_ opcode_ rssi 代码的 WlanQuery Interface () 来返回 RSSI 值作为 LONG 数据类型。您可以从那里将其转换为 dbm 。

DWORD WINAPI WlanQueryInterface(
 __in        HANDLE hClientHandle,
 __in        const GUID *pInterfaceGuid,
 __in        WLAN_INTF_OPCODE OpCode,
 __reserved  PVOID pReserved,
 __out       PDWORD pdwDataSize,
 __out       PVOID *ppData,
 __out_opt   PWLAN_OPCODE_VALUE_TYPE pWlanOpcodeValueType
);

在此使用 opcode wlan_intf_opcode_rssi 来获取 RSSI 值 :

WLAN_INTF_OPCODE  >> wlan_intf_opcode_rssi >> LONG

这里是 C++ 样本, 如何开始 :

Answer 2

Since this question appeared on home page for review- the existing answer is outdated. There is now a Managed Wifi API available as a wrapper around the Windows Native Wifi API.

Signal strength in percentage and RSSI could be obtained as, Wlan.WlanAvailableNetwork[] networks = wlanIface.GetAvailableNetworkList(0);

Wlan.WlanBssEntry[] redes = wlanIface.GetNetworkBssList(); //Get the atribute that you need

foreach (Wlan.WlanBssEntry network in redes)
{
    Console.Write("Network SSID {0} RSSI {1}
 ", GetStringForSSID(network.dot11Ssid),
 network.rssi);
 }
