3. What's The Story??

4. Smart City (1/2)
● Definisi Smart City
Smart City menggunakan teknologi
(utamanya informasi dan komunikasi)
untuk menjadi lebih cerdas dan efisien
dalam penggunaan sumber daya,
menghasilkan penghematan biaya dan
energi, peningkatan layanan dan kualitas
hidup, dan mengurangi economical
footprint - semua yang mendukung inovasi
dan rendah karbon.
● Asal Smart City
Konsep Smart City berawal
saat seluruh dunia sedang
menghadapi salah satu krisis
ekonomi terburuk.
Pada tahun 2008, IBM mulai
bekerja pada konsep 'smatt
city' sebagai bagian dari
inisiatif Smarter Planet.

5. Smart City (2/2)
●
Smart Living
● Smart Building & Home
●
Smart Transportation
● Smart Energy (Renewable generation &
storage, AMI,PQM,PLM,OMS)
● Smart Water Management
●
Smart Waste Management(Recycling of
waste, residual management, Recovery
of waste organics & Energy)
● Smart Education(e-Education)
● Smart Governance(e-
governance)
● Smart Medical Facility(e-
Medical)
● Smart Communications
● Smart Networks
● Environmental Awareness (i.e.
changing weather conditions;
human defined changes)

6. Internet of Things
● The Internet of Things (IoT) is the network of physical objects or "things"
embedded with electronics, software, sensors, and network connectivity, which
enables these objects to collect and exchange data.
● The Internet of Things allows objects to be sensed and controlled remotely across
existing network infrastructure, creating opportunities for more direct integration
between the physical world and computer-based systems, and resulting in
improved efficiency, accuracy and economic benefit.
● Each thing is uniquely identifiable through its embedded computing system but is
able to interoperate within the existing Internet infrastructure.
● Experts estimate that the IoT will consist of almost 50 billion objects by 2020.

8. ● The “conventional” Bluetooth :
– 2.4GHz
– Range: 1m - 100m (10m typical)
– Connection-oriented: audio, file transfer,
networking
– Reasonably fast data rate: 25 Mbps (v3.0)
– Power consumption:
Bluetooth < WiFi < 3G (but still high)

9. &
● Also known as
– Bluetooth v4.0
– Bluetooth Low Energy (BLE)
● Target applications
– Wireless battery-powered sensors eg. heart rate, thermometer, fitness
– Location tracking and information serving eg. iBeacons
● Requirements for target applications
– Low-power
– Low-cost
– Low bandwidth: ~100 kbps
– Low latency: Connectionless (fast setup and teardown of connection in ~10ms)
● How?
– Radio chip off most of the time
– Small packets
● MTU: 20 bytes/packet for application
● Less time transmitting -> less heat -> no need compensatory circuits -> save more power

10. Configuration (1/2)
DEVICE BR/EDR BLE
Pre-4.0 Bluetooth  
4.x Single-Mode (Bluetooth Smart)  
4.x Dual-Mode (Bluetooth Smart Ready)  
BR/EDR (Basic Rate/ Enhance Data Rate or classic Bluetooth)
✔ The wireless standard that has evolved with the Bluetooth Specification since 1.0.
BLE (Bluetooth Low Energy)
✔ The low-power wireless standard introduced with version 4.0 of the specification.
Single-mode (BLE, Bluetooth Smart) device
✔ A device that implements BLE, which can communicate with single-mode and dual-
mode devices, but not with devices supporting BR/EDR only.
Dual-mode (BR/EDR/LE, Bluetooth Smart Ready) device
✔ A device that implements both BR/EDR and BLE, which can communicate with any
Bluetooth device.

12. Broadcast vs Observing
● Broacaster
Sends nonconnectable advertising packets periodically to anyone willing to receive them.
● Observer
Repeatedly scans the preset frequencies to receive any nonconnectable advertising
packets currently being broadcasted.

13. Connections
✔ Central (master)
Repeatedly scans the preset frequencies for connectable advertising packets and, when
suitable, initates a connection. Once the connection is established, the central manages
the timing and initiates the periodical data exchanges.
✔ Peripheral (slave)
A device that sends connectable advertising packets periodically and accepts incoming
connections. Once in an active connection, the peripheral follows the central’s timing
and exchanges data regularly with it.
