History
Why mobile development?
● it pays well● it’s a future● it’s more interesting than building regular
applications
Internet of ThingsInternet of things or IoT is a network of connected computing devices. Complexity of devices varies from simple sensors, to advanced computing devices with UI and high processing capabilities.
Scale of IoT20141.4 billions mobile device 1.5 billion computers
20208 billions connected devices20 - 700 billion IoT devices!

Windows Developer Program for IoT.
WatchKit● Framework designed to create apps for iWatch● Introduced two days ago● Currently requires presence of an iPhone to run
third-party apps. Fully native applications will be available next year.
● Watchkit Apps can be divided into three groups○ Apps - applications with full UI○ Notifications○ Glances - supplemental way for the user to view
important information from your app
IOS TOOLS AND DEMO
iBeaconiBeacon is a name of technology that is enabling new location awareness possibilities for estimation of proximity to a beacon [1] .
Leveraging Bluetooth Low Energy (BLE), a device with iBeacon technology can be used to establish a region around an object. This allows an iOS device to determine when it has entered or left the region, along with an estimated proximity.

1. User enters the beacon’s region2. App recognizes it and starts
approximating it’s distance from/to the beacon
3. app identifies iBeacon, it’s proximity and displays data related to it
iBeacon Use CasesRetailContextualized deals:based on time, location, clientMonitoring Shopping Behaviorstoring and analyzing data about customer’s behaviorIndoor Mapping
EducationContextual learning can be used in libraries, art museums, scavenger hunts, student orientation
HealthcareIdentifying location of patient, doctor.
Home AutomationDetecting user’s location
Social/DatingDetecting users with the same preferences nearby
HospitalityAutomated check in
Proximity and rangeApple Identifies four different proximities defined as CLProximity enumeration type
enum CLProximity : Int { case Unknown case Immediate case Near case Far}Unknown - Location unknown, out of range
Immediate - immediate vicinity most likely right next to the beacon (few inches)
Near - relatively close to beacon (few meters)
Far - relatively close to beacon (more than 10 meters)
Standard beacons have an approximate range of 70 meters. Long range beacons can reach up to 450 meters.
iBeacon AdvertisementEach iBeacon device transmits advertisement with the following fields, that help to identify location of the beacon:
Field Size Description
UUID 16 bytes Most generic, can be used for iBeacons used by app
Major 2 bytes Specifies iBeacon subregion
Minor 2 bytes Further subdivision

Supported HardwareAny device capable of connecting with BLE is capable of interacting with the iBeaconsApple:● iPad Mini or later● iPhone 4s or later● iPod Touch 4th generation or later● iPad 3rd generation or later● Mac Book Air, Mac Book Pro, Mac Pro with BLE
Android● Google Nexus 4,5,7,10● Samsung Galaxy
iBeacon is in almost 200 Million devices around us
Where to get the iBeacon Hardware ?
● Estimote● Gimbail● Kontakt.ioand...Apple! Each device with BLE can serve as a iBeacon
