Inssider signal1/29/2024 (Keep in mind that like the Richter Scale, the dB scale is not linear, but rather logarithmic. Right: WiFi signals going through objects and building materials. Different physical obstacles (and the material that they’re made out of) cause different amounts of loss. Two things cause a low signal strength condition: distance and physical obstacles such as walls and doors. Low signal strength = a low connected rate which creates low throughput over WiFi. Although these modulation methods keep devices connected to the network and passing data, it absolutely slows down speeds as the simpler modulations trade throughput for robustness. In order to keep communication going, WiFi has mechanisms built into it that simplifies the modulation so it’s more robust while dealing with weak transmissions. Relocating or adding wireless access points should be considered.Īs signal strength diminishes, it becomes more difficult for wireless packets to make it to and from wireless stations. For applications like Voice-Over WiFi, vendors recommend -67 dBm as a minimum. A good rule of thumb is that you at least need -80 dBm for any sort of usable connection. What to do: Measure signal strength with inSSIDer Office in the areas you need connectivity. In WiFi, of course this is no different, if there is no signal or very weak signal at the location you need, connectivity is impossible. This concept is obvious, especially since all of us carry mobile phones in our pockets-you’ve got to have signal coverage in order to pass data over the wireless network. Below are some common wireless problems that can be discovered and remedied by using inSSIDer Office. Some of which cannot be overcome by simply buying new WiFi equipment. Slow speeds and connectivity issues can be caused by a number of different unseen variables. Wireless can seem like a mystery, but that’s mostly because it’s invisible.
