1 Introduction to Bluetooth Kirsten Matheus The idea behind Bluetooth The problems when trying to realize the idea The solutions used in Bluetooth How well the solutions work

2 he Idea Behind Bluetooth iversal, short range cable replacement upports speech and data and can be used (almost) worldwide without the need of an infrastructure digital camera car laptop printer mobile phone GSM digital pen headset mobile phone etc. Seite

3 luetooth has to Function in the harsh conditions of the wireless transmission medium Widely used Only with many BT products there is the choice to connect freely as you like Compatible So that the connections may be independent of manufacturer Seite

4 easures to Ensure Distribution: Specification by industrial consortium Ericsson, IBM, Intel, Nokia and Toshiba founded the BT SIG in 1998 Fast because few partners mean fewer opinion that have to be agreed upon Open to be used by anyone No fees for key patents Technical side comparably cheap to realise Chip price today under 5$US Placed in unlicenced frequency band (ISM at 2.4GHz) Almost worldwide deployment without the need to pay licence fees Seite

5 easures to Ensure Compatability: Qualification procedure for every BT product Specific profiles for each application Generic Access Profile TCS-BIN-based Profiles Service Discovery Application Profile Cordless Phone Profile Intercom Profile Serial Port Profile Dial-up Networking Profile Fax Profile Generic Object Exchange Profile File Transfer Profile Headset Profile Object Push Profile LAN Access Profile Synchronization Profile Seite

7 echnical Data Organized in packets access code 72 header 54 payload GFSK modulated data at 1Mbps (1bit ^ = 1symbol) 79 carriers of 1MHz 1mW transmit power (100mW optional) slave 1 slave 3 Master/Slave concept (piconets) Organizes the piconet of up to 7 slaves Determines the hop sequence of FH/TDD-scheme master slave 2 Seite

8 DD/FH Channel f f f f M t S 1 t S 2 Slot = 625 µ s t Frame = 1.25 ms Seite

9 CL Packets (for Data) (A)symmetric, asynchronous services Because data allows no bit errors, ARQ scheme Polling scheme for slaves Quality of data link: Burst requires retransmission Retransmitted bursts are counted in the burst failure rate BFR Causes delay Payload can be used with optional FEC coding (rate 2/3) Up to 10% packet retransmissions ok Seite

10 CL Packet Types short packets are less sensitive to interference have a smaller transmission rate Seite

11 CO Packets (for Speech) Symmetric, synchronous services Speech allows no delay Slot reservation at fixed intervalls Speech quality: Burst is replaced with a 01 bit pattern Replaced bursts are counted in the frame erasure rate FER Distorts the voice Payload (incl. bit errors) is forwarded to the CVSD decoder Bursts with too many bit errors are counted in the unsat. payload rate UPR Causes crackling noise ACL: Up to 10% packet retransmissions ok Payload can be used with optional FEC coding Combined in the unsat. burst rate FER+UPR=UBR 1-2% average UBR per link unacceptable Seite

12 CO Packet Types! HV1 causes three times and HV2 causes 1.5 times! more interference than HV3 but only their! payloads receives more protection Seite

13 acket Types in Overview Type FEC symmetric asymmetric traffic DM1 2/ kbit/s kbit/s kbit/s DM3 2/ kbit/s kbit/s 54.4 kbit/s DM5 2/ kbit/s kbit/s 36.3 kbit/s DH kbit/s kbit/s kbit/s DH kbit/s kbit/s 86.4 kbit/s DH kbit/s kbit/s 57.6 kbit/s HV1 1/3 64 kbit/s HV2 2/3 64 kbit/s HV3-64 kbit/s Speech Data Seite

15 nterference Robustness To interfere with each other different devices have to be used: In the same location At the same time } Depends on user scenario On the same frequency Depends on specification Other Bluetooth piconets Microwave ovens IEEE b WLAN other Seite

16 nterference Robustness slave 3 master master slave 3 slave 1 slave 2 slave 1 slave 2 not like cellular systems blocking, adjacent channel effects hit or miss (interference) Seite

17 nterference in Cellular Systems MT 1 BS MT 2 MT 3 MT 3 BS MT 2 BS MT 1 MT 2 MT 1 MT 1 MT 1 BS BS MT 3 MT 3 MT 1 BS MT 2 MT 2 MT 2 Minimum distance to next co-channel interferer Seite

18 erformance in Case of luetooth interference Radio Network Simulations (in MATLAB) Many simultaneous BT connections Propagation Model Distant dependent fading Shadowing Multipath fading Traffic Models Www-traffic (av.generated data 33.2kbps) Positioning Model 10m by 20m room Uniform distribution of masters Slaves at av. 2m to master in 2-dim Gaussian distribution Seite

19 erformance in Case of luetooth Interference (contd) Average throughput [bits/s] Number of concurrent WWW-sessions At 100 concurrent WWW-sessions only 5% throughput degradation Seite

20 erformance in Case of icrowave Oven Interference Interference of microwave oven depends on: Type (residential or commercial) Oven brand Oven load Position of the receiver towards the oven (in front of window worst radiation) Distance between receiver and oven Seite

21 erformance in Case of icrowave Oven Interference (contd) Seite

22 erformance in Case of icrowave Oven Interference (contd) 9ms (of 20ms mains power cycle) Seite

23 erformance in Case of icrowave Oven Interference (contd) Simulation Parameters: Distance of BT to microwave oven Distance between BT units As expected: The closer the Bluetooth units to each other and the further away they are from the microwave oven the better Data (ACL) transmission is uncritical Speech (SCO) transmission Not critical in PAN environments Degradations will occur only at unfavourable distance ratios Even then the degradation is smooth and Comprehensibility remains Seite

24 erformance in Case of EEE b Interference 02.11b SSS 2MHz 00mW main lobe Bluetooth FH 79x1MHz 1mW first -60 side lobe first side lobe -70 second side lobe and rest -80 second side lobe and rest Cen ter 2.44 GHz 8 MHz/ Span 80 MHz In principle overlap, actual impact (of b on BT or of BT on b) depends on location of units Seite
