There have been many examples of poor rate control algorithms loose in the wild (in both popular AP's and common client devices) that do not actually achieve this monotonic performance, especially when subject to unexpected environmental inputs or certain radio degradations. The physical layer data rate selection algorithm is critical to achieving the monotonically increasing relationship shown here up to saturation. Variability in the environment and in the radios themselves makes real-world wireless throughput a random variable that can only be assessed accurately via statistical methods. All of the details (especially the scale) of this graph are highly dependent on the capabilities of the transmitting radio, the receiving radio and the environment. In fact, at some point (usually a few cm away from the AP) you can eventually run into a signal strength so high that the receiver's front-end is unable to process it, at which point throughput will drop precipitously. (One gross oversimplification is to think of different MCS as being somewhat like different gears on a bike or car.) Once there is sufficient signal strength to operate reliably in the maximum supported MCS rate, additional signal strength does not produce additional throughput gains. The super detailed, professional and technical diagram below shows a typical relationship for any modern wireless system with adaptive modulation: The data transfer speed increases up to a point as signal strength increases since higher signal strengths enable the use of higher PHY (PHYsical layer data) rates, also known as MCS (Modulation and Coding Scheme) in modern Wi-Fi. How does Wi-Fi signal strength relate to data transfer speed?Īll other factors (of which there are many) being equal, stronger signal strength is correlated with higher data transfer speeds, with a couple of exceptions and assuming an optimal physical layer data rate selection algorithm. So here's a good, fairly simple explanation from one of our rocket-scientist founders, Bill Kish, that should help clarify things. The answer, like all answers to WI-Fi questions, can be difficult to get a grip on. One question we constantly get is this: Does a stronger Wi-fi signal always imply faster webpage loading and downloads? If your signal is poor or very poor, this can be caused by the distance between the router and your Ring device, the layout of your home, or interference caused by other devices (TV's, game systems, etc.) or materials in your home such as stucco, brick, metal, large mirrors or glass doors.The relationship between Wi-Fi signal strength and the speed at which data can be transferred over that signal is something that is essential to understand when it comes to Wi-Fi performance. On the Device Health screen, look at your Signal Strength under the Network section.Tap on the Ring device you would like to test.Tap on the three lines on the top left of the screen.To check the strength of your wifi signal, do the following: Signal strength is just as important as speed when it comes to transmitting a video image from your Ring device to your Ring app. If your internet speeds are good, you may still have an issue with the strength of the signal between your router and the Ring device. Poor Connection Between Your Router and Your Ring device If your speeds are much slower than that, you might try moving your router closer to your Ring device or (if necessary) calling your internet service provider to discuss getting faster internet speeds. The blue number in the second column is the upload speed.Īs a general rule, most Ring devices function best when upload and download speeds are around 2 Mbps or greater. The green number in the first column is the download speed. After the test is done, look at the small table under the gauge.Click on the Start button in the center of the gauge to start the test.Open a Web browser on your mobile device and go to Bandwidth Place.Bring your mobile device to the area where your Ring device is installed.To test your internet speed, do the following: That's why it's important to test your internet speed in the area around your Ring device. If either or both of those functions are too slow, your Ring app won't be able to process data from your Ring devices fast enough. "Internet speed" in this context of your Ring devices is the measure of how fast your wireless network uploads and downloads data. Read the following article to learn more about running a connectivity test. You can run a connectivity test when you set up a new device to check the strength of your signal. Since every element of your system uses wifi to communicate with every other element of your system, it’s important to get as strong a signal as possible. One of the most important measurements in your Ring security network is the strength of your wifi signal.
