6 FUNCTIONAL DESCRIPTION

6.1 Baseband

– WLAN coexistence. See also 7.12. WLAN.

6.1.1 Baseband 1.1 Features

The baseband is based on Ericsson Technology Licensing Baseband Core (EBC) and it is compliant with

the Bluetooth specification 1.1:

– Point to multipoint (up to 7 Slaves)

– Asynchronous Connection Less (ACL) link support giving data rates up to 721 kbps

– Synchronous Connection Oriented (SCO) link with support for 2 voice channels over the air interface.

– Flexible voice format to host and over the air (CVSD, PCM 13/16 bits, A-law, µ-law)

– HW support for packet types: DM1, 3, 5; DH1, 3, 5; HV1, 3; DV

– Scatternet capabilities (Master in one piconet and Slave in the other one; Slave in two piconets). All

scatternet v.1.1 errata supported.

– Ciphering support up to 128 bits key

– Paging modes R0, R1, R2

– Channel Quality Driven Data Rate

– Full Bluetooth software stack available

– Low-level link controller

6.1.2 Baseband 1.2 Features

The baseband part is also compliant with the Bluetooth specification 1.2:

– Extended SCO (eSCO) links: supports EV3 and EV5 packets. See also 7.6. eSCO.

– Adaptive Frequency Hopping (AFH): hopping kernel, channel assessment as Master and as Slave. See

also 7.7. AFH.

– Faster Connection: Interlaced scan for Page and Inquiry scan, answer FHS at first reception, RSSI used

to limit range. See also 7.8. Faster Connection.

– QoS Flush. See also 7.9. QoS.

– Synchronization: the local and the master BT clock are available via HCI commands for synchronization

of parallel applications on different slaves.

– L2CAP Flow & Error control

– LMP Improvements

– LMP SCO handling

– Parameter Ranges update
