AVN General Signal for RSSI Article

Way 1: How Can RSSI Affect Your WiFi Network

RSSI is the measurement of the WiFi connection power of either the device connected to our router or access point.  On the flip side your Access Point or Router also measures RSSI.  RSSI can be displayed by either your device connected to your WiFi network or your Router and/or Access Point measurement of the same.  What gets confusing is that this measurement comes in two ranges.  From 0 to 100 being the best or from 0 being the best to -100 being the worst.  Every manufacturer has their own way of measuring this.  Netgear measures this from 0 to -100.  Of course getting to 0 is ultimately impossible but the closer you get the stronger the signal.  Keep in mind Bluetooth also uses RSSI for the same reasons WiFi uses it.  It’s a standardization of Signal Strength.

Way 2: What does RSSI Stand For?

RSSI stands for Received Signal Strength Indicator.  This is a measurement of the strength of a radio signal received by a wireless device, such as a mobile phone, a WiFi Access Point, or a Router.  This will include a Bluetooth device as well as Bluetooth is wireless and uses the same Signal Strength Indicator.

Way 3: What does RSSI Stand For?

RSSI values is often used as a reference for determining the quality of the signal and the distance between the transmitter and receiver.  An example for a WiFi network would be the higher the RSSI value indicates the stronger or better the signal would be which would increase network performance.  While lower RSSI values indicate lower weaker signals it would affect the same WiFi network in the exact opposite way degrading the network performance.

Way4: Why is RSSI Important?

As this is a metric to note the RSSI or “Signal Strength” of the two communicating devices, it shows the quality of the strength of the signal.  Interference, noise and other electro-magnetic noise would also affect RSSI, but the measurement of the RSSI takes all of this to account.   Your RSSI is directly correlated to the network performance of the devices your measuring.

Way 5: The Origin Of RSSI.

The origin of RSSI can be simply traced back to the early days of radio communications when engineers needed a way to measure the strength of radio signals.  In those days, signal strength was measured using a device called a field strength meter, which was typically a portable device that could be carried around to different location to measure signal strength.

With the advent of digital wireless communication, RSSI became an important parameter for measuring signal strength in mobile devices.  Today, almost all wireless devices, including WiFi Routers, Bluetooth device, and mobile phones use RSSI to measure signal strength.  RSSI is typically measured in (Db) decibels, with higher values indicating stronger signals.

Way 6: In a Wonderful AVN Conclusion to RSSI:

In any wireless signal you must be able to see its strength.  Especially for Drones, WiFi, Long Range Autonomous Vehicles, etc.  Without knowing your RSSI you will eventually loose signal strength and loose potentially a lot of $$$.  Your Cell Phone will show RSSI in your WiFi setting where it shows your connection to the router or Access Point.  Just keep in mind the closer you are the higher better RSSI will be.  OR better yet, see how your RSSI is standing on the same point and connect to another router or Access Point to see the strength of said Access Point.  Not all Access Points have the same power outputs.  They are ALL created differently.  It’s a good tool for you to have to see how strong your connection is.  Of course we can go into a lot more detail here, however I think a this is a great overview explain what RSSI is and how it can help you.

I truly hoped this helped you understand RSSI.  IF you have any questions, please feel free to ask.  I will be happy to answer.  This is a very fun topic for me because this is how I test differences between different chipsets of routers and Access Points.  Firmware also.
