# Question: How RSSI Is Calculated?

For point-to-(multi)point applications, the optimal RSSI on each end of the wireless link is between -48 dBm and -65 dBm to achieve the highest possible data rates.

….

RSSI measures the strength of a radio signal. Any RSSI value lower than -80 dBm is considered poor signal strength. … But if the wireless client is in very close vicinity to the AP it can receive signals stronger than -50 dBm as well, which is still OK.

## How can I increase my RSSI level?

How to improve wifi signal and strengthTip #1: Move your router to a more centralized location. … Tip #2: Check for equipment that might be causing an interference. … Tip #3: Change your wireless router channel. … Tip #4: Reduce the number of devices using up the bandwidth. … Tip #5: Make a homemade wifi extender.More items…•

Minimum RSSI (Received Signal Strength Indication) is a value that can be configured on the access point (AP) so that a wireless station (STA) is required to meet a minimum signal level, as seen by the AP, to be able to reliably connect/use a particular AP. This is configured on a per AP basis.

## What does RSSI 42 mean?

RSSI Reading Meaning -66 to -90 is critical and will likely cause a loss of functionality or be unable to maintain a usable connection the wifi altogether. -65 to -41 is sufficient. Possible video issues if constantly at -60. -40 or better is virtually no interference and a very strong signal.

## How is signal strength calculated?

Cellular signal strength is measured in decibels (dB), and typically range from -50 dB to -110 dB. … This means that every 3 dB increase doubles the power. For example, -67 dB is twice the power of -70 dB. Every 6 dB will approximately double the coverage distance from antenna (or cell tower).

An RSSI of -55 (minus 55) is a stronger signal than -70 (minus 70). … If measured in negative numbers, a number that is closer to 0 usually means a better signal, a number that is -50 (minus 50) is a pretty good signal, a number of -70 (minus 70) is reasonable while a number that is -100 (minus 100) has no signal at all.

## What is a good RSSI number?

55Yes, an RSSI value of 55 is generally considered to be good enough for most users and online activities. If measured in negative numbers (with 0 meaning the best signal possible and -100 the worst), then the relative quality of a received signal on a device is slightly worse, but still acceptable.
