The MULF2 will be delivered directly to the car manufacturer. MULF2 is manufactured for BMW AG. BMW AG is responsible for the correct installation of the MULF2. This document is a guide for the correct use of the MULF2. 3 Power supply Normal operation voltage of the MULF2 is 9V – 16V. The nominal supply current of the MULF2 is 180 mA at 14V. The MULF2 may only be operated on a fused power supply. The recommended fuse is a 10A Type. 4 Antenna The MULF2 has an external antenna connector. The connector is a FAKRA type. Only the following antenna should be connected to the MULF2: • 6 928 461 (BMW part number) This antenna has a gain of 2,1 dBi. It is possible, to connect the antenna via a coax cable. 5 Bluetooth 5.1 Generally Bluetooth operates in the 2.4 GHz ISM (Industrial Scientific Medicine) band at 2.4 GHz. A frequency hop transceiver is applied to combat interference and fading. Modulation is GFSK (Gaussian Frequency Shift Keying) with a BT=0.5. The Modulation index is 0.32. A binary one is represented by a positive frequency deviation, and a binary zero is represented by a negative frequency deviation. The symbol rate is 1 Ms/s. For full duplex transmission, a Time-Division Duplex (TDD) scheme is used. On the channel, information is exchanged through packets. Each packet is transmitted on a different hop frequency. A packet nominally covers a single slot, but can be extended to cover up to five slots. The Bluetooth protocol uses a combination of circuit and packet switching. Slots can be reserved for synchronous packets. Bluetooth can support an asynchronous data channel, up to three simultaneous synchronous voice channels, or a channel which simultaneously supports asynchronous data and synchronous voice. Each voice channel supports a 64 kb/s synchronous (voice) channel in each direction. The asynchronous channel can support maximal 723.2 kb/s asymmetric (and still up to 57.6 kb/s in the return direction), or 433.9 kb/s symmetric.
