NFC: Near Field Communication


What is NFC

  • NFC or Near Field Communication is a short range high frequencywirelesscommunicationtechnology

  • A radio communication is establishedbytouchingtwodevices or keepingthem in a proximity of a few centimeters up to 10 cm

  • Allowscommunicationbetween

    • Twopowered (active) devices

    • Onepoweredandone non selfpowered (passive) device

  • Share promotional commercial

  • NFC enabledVending Machine

Benefits of NFC

  • NFC is compatible with existing passive RFID infrastructures unlike Bluetooth.

  • NFC is slow, uses less power and less setup time compared to Bluetooth

  • Uses Short range secured channel for communication which prevents hackers from snooping information during data transfer.


Benefits of NFC

  • Easy to setup andincorporatewith compatible existing systems

    • No special software needed

    • No manual configurationandsettingsneeded

    • No search and pair procedure needed.


Limitations of NFC

  • NFC’s maximum data transfer rate is slower than that of Bluetooth 4.0.

  • Short distance action is a major drawback of NFC


iBeacon/ Beacon / BLE


iBeaCon (iOS + BeaCon)

  • Beacontechintroducedby Apple

  • An extremely accurate locating system

  • Runs on Bluetooth Low Energy (BLE)

  • Push notification system based on location

  • When the device is nearbyanybeacon content, therewillbe a push notification in the device


iBeacon Features

  • Included in Bluetooth 4.0+

  • Geo-fence

  • Peer-to-Peer, WPAN

  • Low power consumption

  • Low cost

  • Multi Vendor interoperability


iBeacon:Multiple points Communication


Some iBeacon examples


Proximity and Microlocation


iBeacon: Benefits

  • Low cost & Low Energy

  • P2P and star network support

  • Wider range than NFC


iBeacon: Limitations

  • Not approved for secured financial transactions

  • Conflicts with different Beacon points is still not handled

  • Turn location monitoring all the time

  • Requires recharging the active device

  • Practical transfer rate is below 100 kb/s

  • iBeacon needs power source.


Beacon in Commercial use

  • Paypal Beacon


Zigbee: PAN, Mesh Network, Ad-hoc digital radio networks


Zigbee: Features

  • Low costand Low Energy

  • Meshnetwork PAN

  • Cantransmit data over long range

  • Operates in the industrial, scientific and medical (ISM) radio bands: 868 MHz in Europe, 915 MHz


Zigbee: Benefits

  • Can not act as bothBeaconand Non-Beacon Mode

  • Remote Sensingand control


Zigbee: Limitations

  • Very low bandwidth

  • Practical range is too low 10-meter range. In comparison the specification is up to 100m

  • ANT+ is the wireless technology that allows your monitoring devices to talk to each other. Leading brands design ANT+ into top products to ensure that you get the data you want -  when and where you want it. Fundamentally, ANT+ gives you the simplest, most expandable and most reliable user experience possible.

  • ANT+ stands for interoperability which means that ANT+ products from multiple brands work together. Plus, because devices are compatible, you can always add to or update your monitoring system.

Ant+: What is Ant+


Ant+: Device Profile

ANT+ devices use the ANT+ network key to access the ANT+ network, and they implement at least one of the ANT+ device profiles.

How NFC Works

Initiator

Target

Reader peak-detects the amplititude modulated

two loop antennas create air-core communication

Receive sufficient energy and starts clocking its data that connected at coils input

Reader continiously generates as RF carrier sine wave at 13,56 MHz

Shunting the coil causes a momentary fluctuation


NFC: Overview


Features of NFC

  • NFC is an extention of Radio frequency Identification (RFID) technology that combines the interface of a smartcard and a reader into a single device.

  • It operates within gobal unlicensed radio frequency band of 13,56MHz with a bandwidth of 14KHz.

  • Supported data rates 106,212 and 424 Kbit/s

  • Setup time is < 0,1 sec

  • Able to receive and transmit data at the same time This solves the problem of recovering data corruption during transmission .

iBeacon - Technical background

  • iBeacon are tinylowcost, low energy, batteryoperatedwireless transmitter

  • iBeacon broadcast small data packet per second using BLE

  • iBeaconenabled Apps are notifiedwhen the mobile device moves in or out of the range of iBeaconusinggeo-location (micro-location) andcontextualinteraction

  • Proximityto a specificiBeaconcan trigger someappfunctionalitytoperform a specific action on a specific mobile device at an exact specific time and in a specificlocation

  • If Apps canconnectto the Net thisinteractioncanbe taken to next stage
