Treat this.
The technical specification of Bluetooth
Please show the highest transfer rate of 723 kbps
Range of 65 - 328 feet, by all
The class of that particular device. Speed is a
Percentage of what is provided by wireless standards,
So, it's obvious that Bluetooth will not do it
It poses a threat to the exchange of wireless networks.
