IBM Internet of Things
Scenario’s
Collect data form all Bluetooth Devices and beacons around via node.js
using a Raspberry Pi or a notebook with Bluetooth Low Energy (BLE)
Send notification when Beacon is within a Range of the Raspberry Pi
(E.g. send sms when one is back from a run using fitbit for example)
Use Raspberry Pi by as a Beacon
Beacon Roaming between 2 gateways

Type
WIFI Grid Locationing Will provide actual (x,y) coordinate of phone Margin of error: 5-10 Meters + variables
WIFI Proximity Provides (x,y) coordinate of the SENSOR that detects you. Margin of error: 2-5 Meters + variables: Dependent on
proximity setting
Beacon/BLE Only provides beacon ID. Server maps that to beacon
location. Margin of error: 1-2 Meters depending on beacon used
and configuration
Small Cell Will provide actual (x,y) coordinate of phone Margin of error: 5-10 Meters + variables
Magnetic Resonance Require no specialized hardware & quite accurate Dependent on establishing a hard location & fingerprinting
of site
SLAM (simultaneous localization and mapping) No hardware required Leverages sensors on the device Used in conjunction w/other sensors
