Wifi & Bluetooth


Recommended Posts

Sorry if this is a topic brought up before, but I have a question regarding using bluetooth and WiFi simultaneously.


On my Note 2, I've noticed that if I'm streaming music to my Jambox, the Wifi connection becomes extremely unstable. Sometimes it disconnects, but it always gives me a much lower throughput (1.8 Mb/s Vs. 25-30) when connected. Once I disable bluetooth it works perfectly fine again. I didn't notice this on my iPhone 5.


Question is this: Does bluetooth operate on 2.4GHz like my wireless router? If so, would it be obvious to deduce that using bluetooth and Wifi at the same time causes interference?


I may just need to invest in a 5Ghz "N" router if need be.

Bluetooth does operate on the 2.4GHz frequency. It also usually uses the same antenna in the device. My semi-educated guess would be that the fact the same antenna is used is causing this issue. It may be an inherent design fault of the antenna/chip used in the device. I haven't noticed a different in WiFi throughput on my GS3, and I have my Pebble constantly paired through BT 24/7.


I also have a 802.11n router, but it only operates at 2.4GHz.

Interesting I wonder if the WiFi signal is weak enough to allow interference to be an issue.


Also wonder if the Exynos SOC in the Note is designed as such that this is problematic vs. the Snapdragon SOC on the GS3

It's just interference, I have had this issue happen to every device I have owned. I run my home network on 5ghz and don't have that issue anymore.

    • What devices should do, and what they actually do, are two very different things! As you've probably heard me mention countless times, many of those screens get information in a proprietary manner directly from the modem; apps like SignalCheck can only get what the OS is reporting. I did find your earlier reports, and as I guessed, the OS was reporting valid signal strength. I will try to figure out a solution.
    • Service mode shows the SIM as having no service, so I would think the device should report that. I believe I sent a diagnostic report a little while back—can you check to see if you have it?
    • Interesting, that doesn't happen on my P7. Can you send me a diagnostic report the next time you see that please? Hopefully the phone isn't actually reporting the -115, that will be tricky.
    • Hey Mike—another dual SIM bug. If one SIM loses service, it doesn’t disappear from the app.  I’ve seen this a couple times—my Dish SIM will lose service (confirmed in service mode), but SCP won’t stop displaying -115 or so. And it logs a data point at that signal every time the location updates.  Along the same lines, I have a custom trigger set up for 313340 (Dish), and the custom trigger keeps firing when this is happening.
