Like many technologies on the market today, Bluetooth experienced its share of weirdness and wrong information. Are you ready to play Bluetooth: Fact or Fiction? Let's go!
Bluetooth® technology was named after a 10th century Danish King.
Fact! The name Bluetooth comes from the 10th century Danish King Harald Blåtand or Harold Bluetooth in English. King Blåtand helped unite warring factions in parts of what are now Norway, Sweden and Denmark. Similarly, Bluetooth technology was created as an open standard to allow connectivity and collaboration between disparate products and industries.
Bluetooth causes headaches.
Fiction! There is no clear evidence that RF waves cause any harmful health effects. Bluetooth headsets have an SAR (Specific Absorption Rate) value of around .001 watts/kg (less than 1/1000th the SAR limit for cell phones set by the FDA and FCC). You can see specific information on who.int.
Bluetooth was created by Hedy Lamarr, a famous actress and inventor.
Fiction (based on fact)! Hedy Lamarr developed spread spectrum and frequency hopping technology, which is incorporated in modern Bluetooth technology and essential for Adaptive Frequency Hopping, which is what makes Bluetooth a good-neighbor technology and limits interference.

A2DP, GATT, HID and BIP are all important Bluetooth profiles.
Fact! A2DP (Advanced Audio Distribution Profile) makes streaming stereo music possible. GATT (Generic Attribute Profile) allows developers to build unique profiles specific for their applications (Bluetooth fork, anyone?). HID (Human Interface Device Profile) makes your Bluetooth enabled mice and keyboards work effortlessly. BIP (Basic Imaging Profile) allows you to send images between devices (other phones, printers, even picture frames).
Bluetooth was initially conceived as a replacement for RS-232 standard cables.
Fact! But its value, and huge success, came from creating a Personal Area Network (PAN) of devices, from light bulbs to headsets and everything in between.
Verizon was famously sued in 2005 for crippling Bluetooth functionality on one of its most popular phones, the Motorola V710.
Fact! Verizon promoted Bluetooth as a reason to buy the phone and then limited the functionality, resulting in a lot of unhappy customers. Read the whole story here.
Bluetooth has worked with several celebrity sponsors, including Lindsay Lohan and Jim Parsons.
Fiction! While all of these celebs have been quoted talking about how great Bluetooth is, none of them are paid sponsors—even celebrities are delighted by Bluetooth technology. Read “Lindsay Lohan Loves Bluetooth,” and watch the clip from The Big Bang Theory.
