Phone antenna??

[Platinum White]

When my cell phone is synchronized to SYNC does my cell phone operate through an antenna powered by SYNC or does it use the phones antenna? A dealers service advisor said SYNC has its own antenna.

I was just wondering which it is.

Your cell phone must connect directly to your cell phone provider using the appropriate transmission format which varies from manufacturer and provider (GSM for AT&T, CDMA for Verizon, etc..), which makes sure it's your phone based on the cell phone ID.

 

Sync then connects to your cell phone with Bluetooth, which most all phones have today. Sync's only wireless connection is this Bluetooth. When SYNC connects through your phone, you are charged by your cell phone provider just like you dialed the numbers yourself. Bluetooth is really just like a remote for your phone.

 

The Bluetooth antennae is very small and embedded in your phone, and another is buried in the car somewhere for SYNC to talk to your phone. So yes, SYNC has its own antennae, a Bluetooth antennae that talks to your phone. And your phone talks to your cell provider.

 

Your car also has an antennae for FM, satellite radio, GPS, etc.. But this antennae is for the dedicated radio or satellite signals to those devices, and separate from SYNC, even though SYNC may control these devices.

 

In contrast, GM's OnStar indeed has a separate independent cell phone connection in each car. But it's nothing to do with your personal cell phone or your cell phone account.
