How do I remove static noise from bluetooth speakers?
Try connecting the speaker to a music source using a stereo audio cable plugged into the Line In Audio socket of the speaker and the headphone socket of a mobile phone (for example).If there is no noise, there may be a problem with the Bluetooth connection. Remove any pairing connections stored in the speaker and also the Bluetooth device (e.g. phone) (see previous answer to you with User Guide link) then re-pair with the Bluetooth source and see if it is still noisy.If it is still noisy, remove the Bluetooth connection 'stored in the speaker and try pairing with a different Bluetooth device, (ensure that the 1st Bluetooth device has the Bluetooth turned off) and see if the noise is still present.If there is noise when using both the Bluetooth and the stereo cable there is a problem within the speaker. There are a lot of things in a powered speaker which, if faulty, can produce unwanted noise and it would have to be opened so that it could be checked to see what is causing the problemYou can do these following stepsStep 1The best and most reliable method for reducing interference is to move the Bluetooth device (the smartphone, the tablet, etc.) closer to the wireless speaker. The further the distance between the device and the speaker, the more interference you are going to get.Step 2Try re-pairing the device with the speaker. Turn off the speaker, and shut off the Bluetooth on your phone or tablet for a few minutes. Turn the speaker back on and re-enable Bluetooth on your device. Finally, reconnect the two devices.Step 3If simple re-pairing doesn’t work, try to use the speaker with a different Bluetooth device. The interference/sound quality issue could be a problem with your mobile device and/or your mobile network service.Step 4Most Bluetooth speakers will give you some option to reset the factory settings. You will have to do research on your specific speaker product to do this, either by looking it up online or reading the owner’s manual.RecapNone of these steps are guaranteed to solve the interference problem you’ve been having with your Bluetooth speaker and your mobile devices. However, all have solved sound quality issues for Bluetooth speaker users at one point or another, so they’re all worth trying if you want to solve the problem.you check out these links alsohttps://www.eevblog.com/forum/beginners/bluetooth-module-noise-issue/
Do floor tiles block/decrease WiFi signals?
TL;DR - yes they do reduce the signal strengthHow much depends on what they’re made of. Most tile is like glass, as far as RF properties go. So there’s a reflection going into and out of the medium with a different dielectric constant (just like light reflecting off a glass window). Then there’s also the actual dissipative loss - most tile isn’t all that bad. It’s not like salt water or human body tissue ( 5–10 dB/cm at WiFi frequencies). 10dB/meter would be a lot.The dominant factor is the reflections at the surfaces - a reflection of 90% isn’t unusual, with only 10% heading on through ( a 10dB loss), and then another similar reflection coming out the other side (another 10 dB loss)There are some particularly lossy materials - I don’t know that I’d want to try and send a signal through flooring designed to be conductive (e.g. for ESD protection). And in a raised floor room, the tiles often have a metal framework or structure, so they are rigid enough.
How do I stop my bluetooth headphones from interfering with my WIFI signal?
If you knew how to measure interference you should've known how to prevent it.But anyway, assuming that you've made an assumption, you can always try the following:Move the WiFi access point farther from your Bluetooth devices. Typically Bluetooth devices have a range of 10 meters so that should be enough.Break and re-establish pairing. It might just help.Change the WiFi channel of your access point. However, this may cause overlaps with your neighbors' access points.If none of the above works, I recommend hiring services from a local professional.Hope this helps.
How does a WIFI signal strength affect the GPS location?
Rachit Srivastava correctly mentioned that WiFi is not directly used in location approximation on phones. But, android phones are known to use Google's WiFi access point database to improve location approximation. Apple's iPhone also have this feature.Whenever your location sharing is turned ON on your android phone, it continuously scans for WiFi networks in vicinity (Even when your phone WiFi is shown to be off. Yup. Refer to 3rd link in provided in the end) and report it to Google. Now, google has SSID information for that area (all WiFi SSIDs seen) and longitude/latitude (location service is on). Google use this info to provide more accurate location to user later. Next time when user will try to use any location service based app, your android will listen to SSIDs available and send those to Google (along with A-GPS). As google already have that information, after correlating it (neighboring SSIDs and other factors), it will help phone to improve accuracy even if you are indoors.Related links:Improve the accuracy of your location Why is location accuracy improved when wi-fi is enabled?

Can walls interfere on a WiFi signal?
You bet. If your RSSI is -67 dBm, replacing drywall with a concrete wall of a certain thickness could decrease the RSSI to -78 dBm and increase packet loss. Walls can absorb, deflect, or duplicate signals, depending on their materials. Which is also why putting a router on a metal shelf is a terrible idea.
Is it better to have your stereo volume all the way up, or your Bluetooth phone volume all the way up, or a 50/50 split?
I am so thankful for you to ask this question. There IS a certain amount of distortion in the BT signal and I shall elaborate on that.Android OS running on most of tablets and non-apple smart phones uses the setting called Volume Control for MEDIA to affect Bluetooth volume from 0 to 60%. As soon as you reach above 60% on the Volume slider on your Android portable device, the SIGNAL ITSELF will become distorted, since you are no longer sending the original digital audio along with an information at which volume it should be played by the BT device, you are ACTUALLY MANIPULATING/AMPLIFYING the digital signal. And as many of you know, amplifying a digital audio signal past -0 dB will result in so called CLIPPING - a situation, where a normal original clear sound-wave gets distorted, because its parts with the highest amplitude get amplified beyond the digitally set limit. The amplitudes get squashed, squared off and a clear sinusoidal sound wave will become a rectangular or saw wave, which makes the audio distorted and hummed.Long story short: Keep your portable device’s volume for Bluetooth broadcast at 50/60% for clear signal.AndAmplify the clear signal to your liking by turning the volume knob in your car/on your Bluetooth speaker etc.Just to clarify, the reason for Android OS to use this two-step amplification, which actually distorts audio is, that originally, BT was designed for voice. And if you absolutely need to understand the other person and NEED their voice louder, you just do not care about the quality anymore. You pay the price of distorting the signal somewhat, because in return, you get the information from the speaker on the other side of the phone line...
