Location based services
• Location-based services (LBS) are applications that leverage the user's physical location to provide an enhanced service or experience.
• Location awareness can be used, for example, for navigation and mapping, workforce tracking, finding points of interest, and getting weather information.
• It presents a compelling new business opportunity for application developers, operators and content producers. Location awareness differentiates mobile applications from traditional PC and wired Internet services.

Global positioning system (GPS)
• The Global Positioning System (GPS) is 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 "visible" 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.

• Accuracy:• 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

RFID localisation - What is RFID?What is RFID?• 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.

RFID localisation - tracking
The origin of RFID in inventory tracking:• 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.

RFID localisation - Electronic Product Code
Tracking Goods with EPC :• 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

RFID localisation - Electronic Product Code
• Why an EPC code doesn’t contain more information: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.

RFID localisation - Technical ChallengesOn the surface, the technology is very straightforward, but there are a number ofvery interesting features, limitations and weaknesses of the systems:
Frequency, Power &Range
• The range of a reader/tag pair is determined by the frequency of transmission and the power transmitted by the reader.
• The RFspectrum is tightly controlled and heavily used. • UHF support ranges around 20-30 feet• HF support ranges up to 2 feet
Interference fromMaterials and RFDevices
• Devices are subject to many sources of interference. • Readers typically cannot penetrate metals or liquids. • Interference also comes from other RF devices like bar
codescanners, cordless phones, walkie-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.

RFID localisation - Technical ChallengesAccuracy of Reads • Fully loaded pallets have a readrate of 66%
• Cases on stocking carts 90% • 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 Environments
• Some environments will contain a number of tags from different manufacturers and systems.

RFID localisation + Wifi
• Active tag including WLAN. • 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 LANwhich means all the complications of setting up network addresses, IP authentication, and so on
• But WiFi is available in most places.

RFID localisation + Wifi
• Solution power problem: tags have to pop up every now and again and say "here I am"
• 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.

Near Field communication
• Consumers are seeking easier ways to interact with their immediate environment and to enable easy communication between their electronic devices.
• NFC are getting their own notoriety as a unique technology, however, they are really just a specific type of RFID that uses the high band of the spectrum (most often 13.56 MHz).
• In addition to the different band, it uses a different form of communication that has an impact on the usable range.
• NFC is all via magnetic waves and has an inverse sixth power (1/r6) relationship with range, which explains why the range is only a few inches because the power to wake up and communicates with the tag diminishes very quickly.
• Simply by bringing two NFC-enabled devices close together, they automatically initiate network communications without requiring the user to configure the setup.

Touch and ConfirmApplications such as mobile payment where the user has to confirm the interaction by entering a password or just accepting the transaction.
Touch and ConnectLinking two NFC-enabled devices to enable peer to peer transfer of data such as downloading music, exchanging images or synchronizing address books.
Touch and ExploreNFC devices may offer more than one possible function. The consumer will be able to explore a device's capabilities to find out which functionalities and services are offered.
