Cellular Phone Forum / General / Bluetooth / October 2007Using a Class 1 headset with Class 2 cell phone
Given: Class 1 Bluetooth headset has a range of 100 meters. Given: Class 2 cell phone has a range of 10 meters. Query: Will the Class 2 cell phone's range also extend to 100 meters when paired with the Class 1 headset? I know that signal clarity will increase due to the boosted signal, but what happens when you put the phone down on the goal line of a football field and start walking away to the 50 yard line? Will the signal drop beyond the 10 meter specification of the Class 2 cell phone? Second query: How does one identify the Bluetooth class of one's Bluetooth-enabled cell phone? My Verizon rep directed me to Samsung for my phone, but the tech support rep couldn't "see that information on her screen." Third query: If one does indeed require a Class 1 cell phone in order to take advantage of the full range of the Class 1 headset, then there must be Class 1 cell phones currently available in the market. Yet, it is not easy to find out from most phone manufacturers about the class. I'm interested to hear the responses... mikesbaker2002@yahoo.com > Given: Class 1 Bluetooth headset has a range of 100 meters. > [quoted text clipped - 7 lines] > Will the signal drop beyond the 10 meter specification of the > Class 2 cell phone? Yes. The range is limited by the class 2 device. You'll probably gain a little extra distance using it in combination with a class 1 device, but it'll be very much closer to 10 metres than to 100. > Second query: How does one identify the Bluetooth class of > one's Bluetooth-enabled cell phone?

Other than that, it's by experimentation, although I've found a lot of variability in the actual range of class 2 devices. My old Siemens phone works happily at over 30 metres to a standard class 1 device, whereas the Sony-Ericsson is much closer to the specified 10 metres. > Third query: If one does indeed require a Class 1 cell phone > in order to take advantage of the full range of the Class 1 > headset, then there must be Class 1 cell phones currently > available in the market. I'm not aware of any class 1 mobile phones. Class 2 devices are more commonly used in industrial applications or for creating local networks. > Yet, it is not easy to find out from most phone manufacturers > about the class.

I find I get noticeably greater distance between my class 1 Parani SD100 Bluetooth RS232 adapter and class 2 phones by fitting the SD100 with the optional dipole antenna (advertised as 400 metres between 2 similarly equipped units).

I haven't read it with my own eyes, but apparently the new Blackjack, Palm Treo, and the Moto SLVR have Class 1 radios.

Of course, this means those of us who *must* have a 100M range BT headset will essentially be "wearing" a cell phone with a 100 mW radio right on their head, thus soaking up plenty of RF goodies. I liken this to folks who refuse to wear motorcycle helmets by saying "I prefer to let evolution take its course." >>>>> "mb" == mikesbaker <mikesbaker2002@yahoo.com> writes: mb> Given: Class 1 Bluetooth headset has a range of 100 meters. mb> Given: Class 2 cell phone has a range of 10 meters. Whoa! Where did you get a Class 1 BT headset?? That would be great for use with Skype: Class 1 BT dongle on your PC, make the connection at the PC then free to wander the house with the BT headset.
