As it turns out, the ubiquitous wireless technology’s name has nothing to do with being blue or tooth-like in appearance and has everything to do with medieval Scandinavia. Harald Bluetooth was the Viking king of Denmark between 958 and 970. King Harald was famous for uniting parts of Denmark and Norway into one nation and converting the Danes to Christianity. So, what does a turn-of-the-last-millennium Viking king have to do with wireless communication? He was a uniter! So his name was given to the wireless link that unites and connects so many devices together. The Bluetooth logo is also a combination of “H” and “B” , the initials of Harald Bluetooth written in the ancient letters (runes) used by vikings (picture below)
So I'm using my Personal Hotspot from my iPhone to get internet connectivity on my iMac and MacBook Air. I can do so either through Wifi or Bluetooth. My wifi tends to not want to connect "automatically" without turning the on/off switch a couple times on the Personal Hotspot (wifi) so I just connected via Bluetooth hoping I can bypass all this connection lag. Next question though is .... Is Bluetooth slower than Wifi? or vice-versa? Just curious if anyone on here knew for sure or could explain it. Thx in advance.
Guest posted a topic in Tesla Motors's TopicsAs we originally reported, Tesla has confirmed that accessing and starting the Model 3 can be done through the use of a keycard but also through one’s smartphone. The Silicon Valley electric car company has ditched the ubiquitous Tesla key fob in the Model 3 for a pair of near-field communication (NFC) keycards that can be used for accessing the car. The cards are embedded with a tiny chip that acts as a digital signature for the vehicle. Since NFC technology generally has a limited transmission range of roughly 4-inches, Model 3 owners will be required to tap the B-pillar to unlock the door, followed by a tap between the front seats to start the car. This would explain why Tesla SVP of Engineering Doug Field was seen placing the keycard inside Model 3’s front cupholders. Tesla has also incorporated a digital key that’s transmitted through a driver’s smartphone using Bluetooth LE, a low energy standard for Bluetooth that’s supported by most smartphones. Unlike Tesla’s current keyless entry system that requires drivers to access a sequence of buttons on its mobile app, Model 3 will use a unique bluetooth signal from your phone to unlock the car as you approach it, and start it when you get inside. The decision to do away with the Tesla key fob that’s currently being used in the Model S and Model X is seen as a move that allows the company to further cut costs on Model 3 production, and reduce complexity wherever possible. We’ve published the full specification list for Model 3 which includes itemized upgrade pricing for its long range 310 mile option. Source
