If your Wi-Fi signal is this strong, you’re likely very close to the access point. -30 dBm – This is the strongest Wi-Fi signal.You’re unlikely to face any buffering and lags, and your download and upload speeds should be quite fast. -50 dBm – This is a stronger signal, and you’ll have faster internet speeds.You can perform all activities that require an internet connection. -70 dBm – This signal strength only supports very low-connection internet activities such as opening emails.You might be able to connect to the network, but you won’t be able to access any internet services. -80 dBm – This signal strength is highly unreliable.With this value, you won’t even be able to connect to the Wi-Fi network. -90 dBm – This is the weakest Wi-Fi signal strength.This way, if this parameter name is "Roaming Agresiveness" for me make no sense it don´t have a "value" to define when/how the roaming decision will be made. I understand that in the past the roaming behavior was not so importante because most of the people put their laptops in "standby mode" to move, but thinking about tablets, this is another history. This IEEE standard make the wireless network send the RSSI information to mobile device to reduce active scans and save battery and give the information that it is necessary to make the roaming(access point) choice. Recently, Microsft anounced the Windows 10 now Support IEEE 802.11k. For Apples and Android devices, the roaming decision is made when the RSSI reach -70 dBm and/or SNR reach 20/25. My wifi environment today is compound by three kind of devices: Laptops (most of them), Smartphones, Tablets and old VoIP phones. In my Wifi Environment Design with Intel Wifi Network Interface Cards, I need to know how the roaming decision is made. In a Wifi environment, it is normal to base the roaming decision in a RSSI (Received Signal Strenght Indication) or/and SNR (Signal-to-Noise Ratio). Learn about Wi-Fi Roaming Aggressiveness Wi-Fi Client Adapter Connection and Roaming Behavior Advanced Intel® Wireless Adapter Settings Here are some advisories about this topic: If you require this type of information, we advise you to check with the Computer Manufacturer Support. We do not have specific dBm values for roaming to take place. If any degradation occurs, it tries to find and roam to a better access point. Highest: Your Wi-Fi client continuously tracks the link quality. Medium: Balanced setting between not roaming and performance. Only significant link quality degradation causes it to roam to another access point. Lowest: Your wireless client will not roam. The options available for Roaming aggressiveness as defined as follows: A very famous one used by many people is the inSSIDer* - *Please understand that this link is being offered for your convenience and should not be viewed as an endorsement by Intel of the content, products, or services offered there. There are third-party tools that can help you track the signal strength. 90 dBm - Aproaching or drowning in the noise floor. In this case, packet delivery may be unreliable. 80 dBm - Minimum signal strength for basic connectivity. 70 dBm - Minimum signal strength for reliable packet delivery such as E-mail, web. 67 dBm - Minimum signal strength for applications that require very reliable, timely packet delivery such as VoIP/VoWIFI, streaming video.and the like. *Not typical or desirable in the real world. The client can only be a few feet from the AP (Access Point) to achieve this. 30 dBm - Max achievable signal strength. It is important to keep this in mind when setting signal strength requirements. Look at this example: A 3 dBm gain means twice the signal strength while 3 dBm loss may represent half of the expected signal strength. What applications will be used, for example: VoIP and/or VoWiFi system.and the like.Īs you know, WiFi is generally measured with dBm which is not an absolute value, being logarithmic instead. The transmit output power of the It is hard to tell which one is better as there are many factors you need to consider in order to place the APs (Access Points) such as:Ĥ.
