Python Access Point Scanning Tool

Created for a university module, in assistance for Wireless Networking Technologies.
The program is used to walk around an area in order to gather information on a routers access point(s).
The idea is to gather the signal strength as well as other info on an access point, while walking from one point of a room to another. This will provide the affective range of a routers access point. Once the data is collected and saved, graph can be generated.

Features

• Create graphs based on the signals collected
• Store data collected

What the project taught me

• How to utilise the command prompt for data collection

• Download .py

Sample of Code:

An example of code, demonstrating how the information is collected using the windows command prompt.

def _scan():
    global signalCol, bssid, x

    scanData = str(subprocess.check_output("netsh wlan show interfaces"))
    nameLoc = scanData.find("Name")
    descLoc = scanData.find("Description")
    bssidLoc = scanData.find("BSSID")
    signalLoc = scanData.find("Signal")
    name = scanData[nameLoc:descLoc-8]
    bssid = scanData[bssidLoc:bssidLoc+42]
    signal = scanData[signalLoc:signalLoc+28]
    print(name)
    print(bssid)
    print(signal)

    bssidComp = bssid
    signalCol = []
    x = 0
    while bssidComp == bssid:
        time.sleep(1)
        scanData = str(subprocess.check_output("netsh wlan show interfaces"))
        bssidLoc = scanData.find("BSSID")
        signalLoc = scanData.find("Signal")
        bssidComp = scanData[bssidLoc:bssidLoc+42]
        signal = scanData[signalLoc+25:signalLoc+27]
        signalCol.append(int(signal))
        print(signal)
        #print(scanData)
        x += 1
