The measurement was made in a two-room apartment of 56 sq.m. The assessment of the parameters is conditional (subjective) in nature and is based on our practical experience and data received from users. Determining the exact values, in this case, is impossible because the strength of the signal Wi-Fi depends not only on the RSSI indicator but also on some other factors (from the radio air traffic, from the signal strength of the access point, from interference, the characteristics of the mobile device). TIP: Note: These values are not absolute. Unacceptable performance: from -85 to -100 dBm.Medium performance: from -65 to -75 dBm.Excellent performance: from -35 to -50 dBm.Here are the approximate values of correspondence between Wi-Fi signal strength and signal quality: At lower power, there will already be a decrease in connection speed, packet loss, and repeated data transmissions (retransmits). Values not lower than -65 dBm can be considered a quality Wi-Fi signal. The higher the RSSI value (closer to 0), the better (stronger) the signal, and the closer to -100, the worse (weaker) the signal. The RSSI can take values from 0 to -100 dBm. Measured by the receiver in dBm (dBm, decibel relative to 1 milliwatt). The received signal strength indicator (RSSI) is used for measuring the strength of the Wi-Fi signal - it is the total power of the signal received by the receiver. From this information, you can determine the signal strength in different rooms and the range of your Wi-Fi network. With apps like this, you can see a list of nearby Wi-Fi networks, the numbers of the radio channels they are currently using, the signal strength of your router's Wi-Fi network, and the signal strength of neighbouring networks. Walk around your apartment with your mobile device running the app and check the signal strength in different places. Wifi Analyzer from farproc, WiFi Analyzer (open-source) from VREM Software Development, WiFi Analyzer from Zoltán Pallagi. There is a wide range of applications to choose from, e.g. Using modern mobile devices, you can easily determine the level of Wi-Fi signal from the access point in different rooms of the apartment, private house, or office.įor example, take your Android smartphone or tablet and install a special free application to determine free channels and check the quality of Wi-Fi signal reception and strength.
