So for the past 2 or so hours I've been trying to determine how far Bluetooth 3.0 can reach, in terms of distance. I know this isn't a CPU specific question but I'm hoping someone might have a general idea. I'm trying to pair a Bluetooth item that I will be wearing, a heart monitor, to my phone which may be up to 40-50 yards (45-50m) away. It will be in an indoor setting, open, no walls or other obstructions. There might be other cell phones around though. I've found the wave lengths and the distances for Bluetooth 1 and 2, but as far as Bluetooth 3.o, I've only came across wave lengths and speeds. Any input would be greatly appreciated, or even if you could point me in the right direction i don't' mind doing some research. I'm really striking out with my search terms.
What I'm trying to do.
I'm playing indoor soccer and would like to wear a heart monitor on me. I've found one that I can pair to my phone via Bluetooth and then have my results on hand using various compatible apps. The idea is that if I'm wearing the monitor, I can leave my phone in my bag on the sidelines and it'll hopefully collect data throughout the game. An indoor field is roughly 200ft long (67ft or 60M). I can have my bag, or even the phone, at roughly midfield.
Roughly how far can Bluetooth 3.0 reach, distance wise, with no walls or obstructions?
Thank you in advance for any suggestions or help.
