Understanding -90 Noise in Wi-Fi
What is -90 Noise?
-90 noise, also known as -90 dB or -90 Hz, is a type of electromagnetic interference (EMI) that can be a significant issue for wireless networks. It is a low-frequency noise that falls within the range of 0.1 to 10 Hz, which is below the range of human hearing.
Causes of -90 Noise
-90 noise can be caused by a variety of factors, including:
- Electrical equipment: Power lines, transformers, and other electrical equipment can generate -90 noise.
- Industrial processes: Industrial processes such as manufacturing, mining, and construction can also generate -90 noise.
- Transportation: Vehicles, trains, and airplanes can also generate -90 noise.
- Natural sources: Natural sources such as thunderstorms and earthquakes can also generate -90 noise.
Effects of -90 Noise on Wi-Fi
-90 noise can have a significant impact on wireless networks, including:
- Interference: -90 noise can cause interference with wireless signals, leading to dropped connections, slow speeds, and poor performance.
- Latency: -90 noise can also cause latency, which is the delay between when a packet is sent and when it is received.
- Packet loss: -90 noise can cause packet loss, which is the loss of packets in transit.
- Network instability: -90 noise can cause network instability, including crashes and freezes.
Signs of -90 Noise
-90 noise can be difficult to detect, but there are some signs that may indicate its presence:
- Intermittent connectivity issues: If you experience intermittent connectivity issues, such as dropped connections or slow speeds, it may be due to -90 noise.
- Latency: If you experience latency, such as a delay between when a packet is sent and when it is received, it may be due to -90 noise.
- Packet loss: If you experience packet loss, such as missing packets in transit, it may be due to -90 noise.
- Network instability: If you experience network instability, such as crashes or freezes, it may be due to -90 noise.
How to Reduce -90 Noise
Reducing -90 noise can be achieved through a combination of hardware and software solutions. Here are some steps you can take:
- Use a high-quality antenna: Using a high-quality antenna can help to reduce -90 noise.
- Use a Wi-Fi range extender: Using a Wi-Fi range extender can help to extend the range of your wireless network and reduce -90 noise.
- Use a Wi-Fi analyzer: Using a Wi-Fi analyzer can help to identify the source of -90 noise and take steps to reduce it.
- Upgrade to a Wi-Fi 6 router: Upgrading to a Wi-Fi 6 router can help to reduce -90 noise.
