I have one user who has a 7100g and he has been having problems with his wireless mouse for as long as it seems as he has had his BlackBerry. This could be mearly coincidence, but we have been through two top of the line Microsoft wireless keyboards and mice and we have had the same problem.

Are there any known issues with BlackBerry devices interfering with wireless keyboards or mice??

Please help!


Thanks,

Do you have a Bluetooth keyboard or a standard IR keyboard. I have wireless keyboards and mice EVERYWHERE and have never had an issue with the 7100t or the 7290 (or any other BBs for that matter).

We are using the standard IR keyboard and mouse. I have never seen anything like this and at this point I am just grasping at straws.

My 7100g makes all kinds of noise on my speakers when I have messages coming in. I wonder if the RFI is causing the problems?

C'mon - that is the GPRS noise that is being picked up by unshielded speakers. It has nothing to do with wireless mice.

I'm pretty sure that with my limited knowledge of RF, the F being frequency has something to do with it, and as long as your wireless mouse isnt working at band they shouldn't interfere.

However I did hear that UMTS networks can/will run at 2.5ghz, so does my router and cordless phone... that might create a problem? Anyone have any feedback on that?

Tell the user to move his phone away from the mouse.

GSM uses narrowband transmission which will easily interfere with poorly shielded electronics. The phone is actually causing problems with the electronics in the mouse--not interference on the wireless frequency used by the mouse.

I've had GSM devices (and TDMA) interfere with my landline phone, my keyboards, my monitors and other electronics. It can be a pain...

I thought most routers, cordless phones and bluetooth devices operate at 2.4GHz?

They do.

Well after reading this I was using my ibm thinkpad and noticed my cursor going across the screen I moved my BB7520 and it stopped was really kind of weird. I had seen this happen a few times but never put two and two together. I have an ir port on the thinkpad its kind of freaky seeing the cursor statr moving in the middle of the night.

RF is a radio freq. transmition, IR is infared light and limited to line of sight
I don't see how a radio transmition is going to intefere with an IR light.

IR doesn't transmit a radio signal on any band or freq. it simply blinks a light at variable rates and the IR receiver picks up that light and translates it. About the only thing that will intefere with IR is sunlight, glass, and solid walls.

After reading this thread I just had to test it.

I installed a 'Dick Smith' Brand wireless mouse on the desktop and began testing a 7100g and its effect on the cursor.

Testing: email send/receive, PIN to PIN send/receive, Power Off/ON, Wireless Off/On, making/receiving a call, waving it around.

I did manage to get a small downward cursor movement of aproximatly 20 pixels when receiving a PIN to PIN message one time but could not repeat it a second or third time.

Myth Busters?

Well a vast majority of the wireless keyboards and mice out there use RF as their wireless medium NOT IR. So does it make more sense now.

My niece was over here yesterday, so I decided to test this out too. I handed her my BlackBerry 7100t and she started moving with it. It was quite incredible. I took the handheld back and IMMEDIATELY she started crying! I handed it back to her, and then she stopped! It was quite amazing, I swear.

I can speak from experience that my 7510 DOES interfere with my Microsoft Wireless Optical Mouse at home, as well as my Microsoft Wireless Intellimouse Exporer @ the office.

When the 7510 is between the mouse and receiver, both mice move irratically. Solution for me is simple: relocated the USB cable that I sync the blackberry with, so that the unit isn't between the mouse and the receiver

My 7520 did the same thing. I had to upgrade to a Bluetooth setup.

Did upgrading to Bluetooth eliminate your problems for you?

Sure did. I have a Microsoft bluetooth setup at one desk, and a Logitech bluetooth setup at the other. Both work well, though I'm partial to the Logitech.

I have heard some people mention that they have a latency problem with the Bluetooth keyboard and mouse, especially when they step away from the computer for a few minutes and come back. One guy in particular mentioned that it takes him tapping the spacebar a couple of times to get his Bluetooth to "wake up." Could his problem be a particular setting on the devices or is this a known issue with Bluetooth?

I think it may be a problem with GSM850 or iDen which is also in the 800 mhz range. Most mice and keyboards that are not BT use something in that range.
