Iden%fying Loca%ons Using Mobile Devices
Mobile Device Loca%on Resolvers
• Quick Response Code (QRC)
• Near Field Communica%on (NFC)
• Bluetooth
• WiFi
• GPS
Mobile Device Loca%on -‐ Outdoors
• Global Posi%oning System (GPS) – Satellite based naviga%on system. – Network of 24 satellites. – Typical GPS receiver (i.e.: mobile phone) will have an accuracy of 1-‐5 meters.
– Building construc%on materials significantly degrade the signal quality.
– Not suitable for indoors.
Mobile Device Loca%on -‐ Indoors
• Indoor Posi%oning Systems – Typically use radio waves or magne%c fields. – There is currently no de facto standard. – Wireless Technologies:
• Quick Response Codes (QR Codes) • Near Field Communica%on (NFC) • Bluetooth • WiFi
Quick Response Codes
• Two dimensional barcode. • Provides error correc%on. • Ini%ally used to track parts in vehicle manufacturing.
• Can store up to 4,296 alphanumeric characters.
• Free QR Code genera%ng websites. • Does not accurately indicate loca%on. • Can be scanned from a distance or angle.
Near Field Communica%on (NFC)
• Uses electromagne%c induc%on. • The NFC ini%ator (mobile device) generates an RF field that powers a passive NFC tag (unpowered chip).
• The NFC tag can store between 96 and 4,096 bytes of data and are Read Only.
• When the tag is scanned, an ac%on typically takes place at the mobile device (i.e.: a website is launched, a payment is made, etc.)
Near Field Communica%on (NFC)
• Most Android devices ship with NFC support. – Relevance will support Android NFC in its next release.
• iPhone 6 and iPhone 6 Plus have NFC as well but limited to use with Apple Pay.
• iPad Air 2 and iPad mini 3 only support Apple Pay within apps.
Bluetooth
• Beacons use the Bluetooth Low Energy Standard (BLE). – Different from Bluetooth Classic. – Included in mobile devices with Bluetooth 4.0.
• Transmits a unique signal mul%ple %mes every second which can be received by mobile devices up to 50 meters away.
• Signal strength of the Beacon is related to distance from the Beacon.
• Beacons come in all forms and shapes with diverse chipsets, ba^ery sizes and firmware.
Bluetooth -‐ iBeacon
• iBeacon is Apple’s version of the Bluetooth beacon.
• Supported in ThinManager 8.0. • End user specifies: – Universally Unique Iden%fied (UUID) – Major ID – Minor ID
• The firmware can control Transmit Power and Adver%sing Interval which will impact ba^ery life.
• Some iBeacons have their own iOS app for configura%on.
Bluetooth
• Beacons come in all forms and shapes with diverse chipsets, ba^ery sizes and firmware.
• While most are ba^ery powered, there are some that are externally powered (USB).
WiFi
• A Service Set ID (SSID) uniquely iden%fies a WLAN. • Packets bound for devices within the WLAN need to go to the correct des%na%on.
• The SSID keeps the packets within the correct WLAN even when overlapping WLANs are present.
• With mul%ple access points within each WLAN, there has to be a way to iden%fy each one.
• Basic Service Set Iden%fier (BSSID) is included with all wireless packets.
• BSSID is like a MAC Address for the access point.
Demo – Registering Resolvers
• QR Code • Bluetooth Beacon – Received Signal Strength Indica%on (RSSI) – Use RSSI to determine entry and exit points
• WiFi – Use BSSID (Access Point MAC Address)
• GPS – Establish Loca%on Radius and Al%tude Range
