 3 | Simple Wi-Fi analyzer for macOS built in SwiftUI.<br>
 4 | 
 5 | 
 6 | It displays your Signal to Noise Ratio and Received Signal Strength.<br>
 7 | Basestation SSID and MAC-address, you can export measured data as<br>
 8 | a csv file to import to Numbers/Excel by rightclick the play button.<br>
 9 | 
10 | System requirements<br>
11 | macOS 11.0 <br>
12 | 
13 | Download from here:<br>

20 | **Signal to Noise Ratio (SNR)**<br>
21 | Higher value is better<br>
22 | 
23 | Its measured by taking the signal strength (RSSI)<br>
24 | and subtracting the noise.<br>
25 | Noise is all the RF around the radio in the spectrum<br>
26 | from all RF sources. It can come from a microwave, bluetooth devices, etc.<br>
27 | 
28 | Wireless adapters (NIC) for laptops, tablets,<br>
29 | aren’t capable of determining accurate SNR.<br>
30 | An example is when a microwave is turned on.<br>
31 | The NIC will not be able to see the RF signal<br>
32 | because the microwave is sending unmodulated bits.<br>
33 | Thus the built-in NIC believes there is no noise.<br>
34 | <br>
35 | **Received Signal Strength Indicator (RSSI)**<br>
36 | Measured in dBm (decibel milliwatts)<br>
37 | 
38 | Lower value is better<br>
39 | Every 3 dB lower = doubles signal strength<br>
40 | Every 3 dB higher = halves signal strength<br>
41 | Usually it starts around -30 near the access point,<br>
42 | and gets higher (losing strength)<br>
43 | when moving away from the access point.<br>
44 | <br>
45 | **Basic Service Set Identifiers (BSSID)**<br>
46 | Most of the time it is associated with MAC address of the access point
47 | Stick to current BSSID until:
48 | - RSSI below -75dBm
49 | - Choose 5Ghz over 2.4GHz as long as 5GHz is more than -68dBm
50 | - Does NOT support 802.11k
51 | - Choose AP with RSSI 12dB higher than current AP
52 | 
53 | If multiple 5 GHz SSIDs meet this level,
54 | macOS chooses a network based on these criteria:
55 | - 802.11ax is preferred over 802.11ac.
56 | - 802.11ac is preferred over 802.11n or 802.11a.
57 | - 802.11n is preferred over 802.11a.
58 | - 80 MHz channel width is preferred over 40 MHz or 20 MHz.
59 | - 40 MHz channel width is preferred over 20 MHz.
