2 The Family Target environment: communication of personal devices working together Short range Low power Low cost Small number of devices Four Standards IEEE Bluetooth IEEE Interoperability IEEE High Data Rate WPAN IEEE Low Data Rate WPAN (ZigBee) 2

3 What is Bluetooth? It is a universal radio standard for adhoc wireless connectivity with the following characteristics: Low cost of Bluetooth modules Short range (10m) Low power consumption Operates license free at 2.45 GHz Used for voice and data transmission (1Mb/s gross data rate) 3

4 What is Bluetooth? Bluetooth History Ericsson started a research project on Bluetooth in 1994 Bluetooth SIG (Special Interest Group) was founded in Version 1.1 of consumer products was released to the market in 2001 Development until 2017 SIG hosts 30,000 member companies Bluetooth can be found in 90% of all mobile devices More than 2.5 billion products shipped annually 4

5 What is Bluetooth? Strange name? Named after 10 th century Viking King (Harald Blatand, A.K.A., Bluetooth) The king had peacefully united all the tiny island kingdoms of Denmark, Southern Sweden and Southern Norway in one country Bluetooth was named after him since it was designed as a low-cost radio technology to unite or collect all different types of devices to effectively work as one 5

6 Bluetooth Characteristics 2.4 GHz ISM band, 79 RF channels, 1 MHz carrier spacing Channel 0: 2402 MHz channel 78: 2480 MHz G-FSK modulation (Gaussian Frequency Shift Keying), mw transmit power FHSS and TDD Frequency hopping with 1600 hops/s Hopping sequence in a pseudo random fashion, determined by a master Time division duplex for send/receive separation 6

7 Bluetooth Characteristics Voice link SCO (Synchronous Connection Oriented) FEC (forward error correction), no retransmission, 64 kbit/s duplex, point-to-point, circuit switched Data link ACL (Asynchronous Connectionless) Asynchronous, fast acknowledge, point-to-multipoint, packet switched Topology Overlapping piconets (stars) forming a scatternet 7

8 What is a Piconet? Collection of devices connected in an ad hoc fashion One unit acts as master and the others as slaves for the lifetime of the piconet The master is the unit that establishes the piconet Master determines hopping pattern, slaves have to synchronize Each piconet has a unique hopping pattern Participation in a piconet = synchronization to hopping sequence 8

9 What is a Piconet? Each piconet has one master and up to 7 simultaneous slaves ( >200 could be parked) If more than 7 devices are to be connected, extra devices will be put into low power mode (Parked) When a parked device wants to actively participate in the network it does so by exchanging roles with the least active device Nodes in Standby mode have their radio switched-off 9

10 Forming a Piconet Any two or more device can form a piconet where the device establishing the piconet becomes the master Master sends its clock and device ID to the slaves Hopping pattern determined by the device ID Phase is determined by the clock of the master Addressing: Active Member Address (AMA, 3 bit) Parked Member Address (PMA, 8 bit) 10

11 Scatternet Scatternet = group of piconets Device can participate multiple piconets Jumping between hopping sequences of the different piconets Before leaving a device informs the current master that it will be unavailable for a certain amount of time A device can be a slave in one piconet and master of another 11

14 Bluetooth Radio Layer Uses license free 2.4 GHz 1600 hopes per second 79 hop carriers with 1 MHz spacing Use three Power classes Class 1 maximum power of 100mW and min power of 1 mw Power control is mandatory Class 2 maximum power of 2.5 mw and min power of 0.25 mw 10 m typical range Power control optional Class 3 Maximum power is 1 mw 14

16 Bluetooth Baseband Access code Needed for timing, synchronization, and pioneer identification It may represent special codes during paging (device access code) and inquiry Synchronization field is derived from the lower 24 bits of an address If access code is used for channel access it is derived from the master 48 bit address In case paging the LAP (Linear Address Pointer) of the paged device is used For discovery a special LAP is used access code packet header payload 68(72) bits 4 64 (4) preamble sync. (trailer) bits AM address type flow ARQN SEQN HEC 16

17 Bluetooth Baseband Packet Header 1/3-FEC, active member address (broadcast + 7 slaves), link type, alternating bit ARQ/SEQ, checksum 68(72) bits access code packet header payload 4 64 (4) preamble sync. (trailer) bits AM address type flow ARQN SEQN HEC 17

18 Bluetooth Baseband Link Types Polling-based TDD packet transmission 625µs slots, master polls slaves SCO (Synchronous Connection Oriented) Voice Periodic single slot packet assignment, 64 kbit/s full-duplex, point-to-point ACL (Asynchronous Connectionless) Data Variable packet size (1, 3, 5 slots), asymmetric bandwidth, point-to-multipoint MASTER SCO ACL SCO ACL SCO ACL SCO ACL f 0 f 6 f 8 f 12 f 4 f 20 f 14 f 18 SLAVE 1 f 1 f 7 f 9 f 13 f 19 SLAVE 2 f 5 f 21 f 17 18

Each SCO carries voice at 64 Kbit/s and 0,2/3 or 1/3 FEC 20
