Technical perspective - Faster Connection
The Faster Inquiry functionality is based on a removed/shortened random back off and also a new Inter-
laced Inquiry Scan scheme.
The Faster Page functionality is based on Interlaced Page Scan.

User Perspective - Quality of Service
Small changes to the BT1.1 spec regarding Quality of Service make a large difference.
Allowing all QoS parameters to be communicated over HCI to the link manager enables efficient band-
width management. Here after a short list of user perspectives:
1) Flush timeout: enables time-bounded traffic such as video streaming to become more robust when the
channel degrades. It sets the maximum delay of an L2CAP frame. It does not enable multiple streams
in one piconet, or heavy data transfer at the same time.
2) Simple latency control: allows the Host to set the poll interval. This provides support for HID devices
mixed with other traffic in the piconet.

All the provided values are specified over the operational conditions (VDD and temperature) according to
the Bluetooth 1.1 and 1.2 specifications unless otherwise specified.
GENERAL SPECIFICATION
7.1
To be compliant with the Bluetooth norm, an external RF filter is required to provide minimum -17dB of
attenuation in the band: 30MHz - 2000MHz and 3000MHz - 12.75GHz. All specifications below are given
at pin level and over temperature unless otherwise specified.
