  10. 10. LOCATION BASED SERVICES Global positioning system (GPS) • The Global Positioning System (GPS) is www.mastersininnovation.com actually a constellation of 27 Earth- orbiting satellites (24 in operation and three extras in case one fails). • Satellites circle the globe at about 19,300 km, making two complete rotations every day. • The orbits are arranged so that at any time, anywhere on Earth, there are at least four satellites quot;visiblequot; in the sky. • A GPS receiver's job is to locate four or more of these satellites, figure out the distance to each, and use this information to deduce its own location. 20.10.2006 Slide 10
  11. 11. LOCATION BASED SERVICES Global positioning system (GPS) • GPS functionality can be used by www.mastersininnovation.com emergency services and location based services to locate mobile phones • The mobile phone location may also be used to provide location specific information to the mobile phone, such as location specific advertising, or providing service information specific to the phone user's geographic location • Location based games: • search for objects hidden by other geocachers • walking or hiking to natural locations • ....... 20.10.2006 Slide 11
  12. 12. LOCATION BASED SERVICES Global positioning system (GPS) • Accuracy: www.mastersininnovation.com • The receivers do this by measuring the time delay between when the satellite sent the signal and the local time when the signal was received • The location accuracy is anywhere from 1 to 100 meters depending on the type of equipment used 20.10.2006 Slide 12
  13. 13. LOCATION BASED SERVICES www.mastersininnovation.com Mobile positioning 20.10.2006 Slide 13
  14. 14. LOCATION BASED SERVICES Mobile positioning – Cell ID • GSM is the digital radio network for www.mastersininnovation.com mobile telephony and the positioning system takes advantage of the fact that base stations are placed for the best possible coverage • Mobile positioning technologies 1. Terminal (device) based technologies (A-GPS / E-OTD) 2. Network based technologies (E-CID / U-TDOA) 3. Hybrid solutions (combination of 1 & 2) 20.10.2006 Slide 14
  15. 15. LOCATION BASED SERVICES Mobile positioning (A-GPS) • A-GPS (Assisted GPS) www.mastersininnovation.com • Uses an assistance server to cut down the time needed to determine a location using GPS • Useful in urban areas • No indoor coverage 20.10.2006 Slide 15
  16. 16. LOCATION BASED SERVICES Mobile positioning (E-OTD) Enhanced Observed Time Difference www.mastersininnovation.com • A position-location method for GSM networks in which the phone measures the difference in the time of arrival signals from different towers • The phone triangulates its position using signals from the towers • Only works with phones that specifically include E-OTD technology 20.10.2006 Slide 16
  17. 17. LOCATION BASED SERVICES Mobile positioning (E-CID) CID • CID: Cell Identification www.mastersininnovation.com • The accuracy of this method can be as good as a few hundred meters in urban areas, but very poor in suburban areas and rural zones. LB E-CID • E –CID: Enhanced Cell Identification • Higher accuracy by using • TOA (time of arrival) *Cell Global Identity LBS • AOA (angle of arrival) • Neighbouring cells 20.10.2006 Slide 17
  18. 18. LOCATION BASED SERVICES Mobile positioning (U-TDOA) • U-TDOA :Uplink the difference of www.mastersininnovation.com arrival • Method calculates the location of a handset by using the difference in time of arrival of signals at different receivers. • The handset or device could be a standard mobile phone or PDA. • Accuracy is under 50 meters. 20.10.2006 Slide 18
  19. 19. LOCATION BASED SERVICES www.mastersininnovation.com RFID localisation 20.10.2006 Slide 19
  20. 20. LOCATION BASED SERVICES RFID localisation - What is RFID? What is RFID? www.mastersininnovation.com • RFID = Radio Frequency Identification • Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. • An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Chip-based RFID tags contain silicon chips and antennas. Passive tags require no internal power source, whereas active tags require a power source. 20.10.2006 Slide 20
  21. 21. LOCATION BASED SERVICES RFID localisation - tracking The origin of RFID in inventory tracking: www.mastersininnovation.com • Wal-mart has spent millions of dollars since the late 1990s researching the efficiency of RFID systems to replace the bar codes (which have been in use since the early 1970s) • In 1999, with the help of scientist of the Massachusetts Institute of Technology (MIT), a consortium of companies formed the Auto-ID center – a center for continued research into the nature and use of radio frequeny identification. 20.10.2006 Slide 21
  22. 22. LOCATION BASED SERVICES RFID localisation - Electronic Product Code Tracking Goods with EPC : www.mastersininnovation.com • EPC = Electronic Product Code (Developed at MIT’s Audio center in 2000) • EPC is modern day replacement for the Universal Product Code (UPC) • A tag embedded EPC number is unique to the Tag • The EPC protocol is universal to all EPC compliant systems and serve two specific functions: • Telling how data is to be stored on the tag – numbering scheme • Determining how tag and readers communicate – air interface protocol 20.10.2006 Slide 22
  23. 23. LOCATION BASED SERVICES RFID localisation - Electronic Product Code • Why an EPC code doesn’t contain more information: www.mastersininnovation.com 1. Security: Like a car license plate, every car has its own license plate but you need to have access to a database to find out who owns the car, where the owner lives and other private information. The same applied to EPC; it points to a file in a database, so this information stays secure. 2. Cost: Delivering a very low cost tag was one of the primary goals of the Auto-ID Center. Memory on an IC is one of the drivers for the cost. 20.10.2006 Slide 23
  24. 24. LOCATION BASED SERVICES RFID localisation - The basic physics of RFID 1. RFID reader www.mastersininnovation.com 2. The Tag (active or passive – technologies antennas) 3. Frequency – Air Protocol 20.10.2006 Slide 24
  25. 25. LOCATION BASED SERVICES RFID localisation - Main operating frequency www.mastersininnovation.com 20.10.2006 Slide 25
  26. 26. LOCATION BASED SERVICES RFID localisation - Technical Challenges On the surface, the technology is very straightforward, but there are a number of very interesting features, limitations and weaknesses of the systems: www.mastersininnovation.com • Frequency, Power & The range of a reader/tag pair is determined by the frequency Range of transmission and the power transmitted by the reader. • The RFspectrum is tightly controlled and heavily used. • UHF support ranges around 20feet -30 • HF support range to 2 feet s up • Interference from Devices are subject to many sources of interference. • Materials and RF Readers typically cannot penetrate metals or liquids. Devices • Interference also comes from other RF devices like bar codescanners, cordless phones, wa lkie-talkies, wireless networks,and security systems. • Multiple Reads The RF wave from a reader triggers transmission in all tags within range. • Reader must contend with multiple simultaneous signals and multiple transmissions from each tag. 20.10.2006 Slide 26
  27. 27. LOCATION BASED SERVICES RFID localisation - Technical Challenges • Accuracy of Reads Fully loaded pallets have a readrate of 66% • Cases on stocking carts 90% www.mastersininnovation.com • Conveyor belts 95%, • Trash compactors 98%. • Triangulation Identifying the location of a specific tag requires triangulation from multiple readers that are placed in very specific patterns. • A large number of readers are required to provide locations in a large area. • Speed of reading Cases move through distribution center at 8 MPH. • Readers must correctly identify a product at this pace. • Hacking Hackers can read tag data anywhere, anytime. • For active tags, hackers may also be able to write and overwrite data on the tags. • Encryption • Data fusion In a tag-dense environment (like an Airbus A380), a reader will receive a large number of reads in a single scan. • This will create a need for data fusion algorithms within the computers receiving the data. • Competing Tag Some environments will contain a number of tags from different Environments manufacturers and systems. 20.10.2006 Slide 27
  28. 28. LOCATION BASED SERVICES RFID localisation + Wifi • Active tag including WLAN. www.mastersininnovation.com • Conventional idea would be to use something like Zigbee. • WiFi -> absurd for this type of job: • far too power-hungry (most power- hungry of all short range wireless technologies) • far too difficult to integrate into a LAN which means all the complications of setting up network addresses, IP authentication, and so on • But WiFi is available in most places. 20.10.2006 Slide 28
  29. 29. LOCATION BASED SERVICES RFID localisation + Wifi • Solution power problem: tags have to pop up www.mastersininnovation.com every now and again and say quot;here I amquot; • Powered by standard AA batteries will position and track any asset equipped with a tag. • Items that move around a lot (like wheelchairs) can be set to send a signal more often than items that are relatively stationary (like heart monitors). • They don't go into sleep mode -> they completely shut off when not transmitting. They're only associated for the few seconds that they transmit. 20.10.2006 Slide 29
  30. 30. LOCATION BASED SERVICES www.mastersininnovation.com Tracking algorithm 20.10.2006 Slide 30
  31. 31. LOCATION BASED SERVICES Tracking algorithm – Kalman Filter Kalman filter invented in www.mastersininnovation.com 1960 by R. E. Kalman Problem: • System state cannot be measured directly • Need to estimate “optimally” from measurements 20.10.2006 Slide 31
  32. 32. LOCATION BASED SERVICES Tracking algorithm – Kalman Filter www.mastersininnovation.com y • Lost on the 1-dimensional line • Position – y(t) • Assume Gaussian distributed measurements 20.10.2006 Slide 32
