Introduction
The ‘smart city’ is the ability to access any
application at anytime from anywhere
Smart Cities should implement
e-health
e-government
e-commerce systems
Cities become “Smarter” with
Object Identification
Network of things
High speed Wireless Network
Monitoring by Sensors
Cities become “Green” with
Low power consumption

RFID Technology
Object Recognition/ tracking system
RFID system consists
transponder (i.e., the tag itself)
transceiver (i.e., the reader)
To track any object it uses an EPC
An EPC is either 64-bit or 96-bit identifier
Header-2 bits
EPC Manager- 21 bits
Object Class- 17 bits
Serial Number-24 bits
H
EPC Manager Object Class

IEEE 802.11b Standard
High speed Wireless Networks or
Wi-Fi
Extension of IEEE 802.11standard
to IEEE802.11b standard
Applies to wireless LANs
Provides 11Mbps to 55Mbps Data
transmission rate
2.4 GHz ISM frequency band

Proposed System
RFID experiencing problem
Vendor Specific
High implementation cost
Local mobility
The proposed System will
Use WNIC instead of Reader
Use IPv6 in RFID system
Use IEEE 802.11 standards, perhaps
better known as WiFi Protocol
A low power transponder IC

Objective
To design a high speed, efficient and low
power tag IC using mapped EPC-IPv6
address for the future green city
To employ IEEE 802.11 standard for
WLAN instead of proprietary standard of
RFID Reader for a smarter city
To develop a Computer Application to
extract data from the tag

Conclusion
By Using the Proposed System
A low power tag IC will be developed to make
the city “Green”
The cost of efficient RFID tagging system for
future smart city will be reduced
Possible to find out the physical location of any
objects, which is one of the prime element of
smart city
Provide Global Mobility
Increased Scalability, Reliability, and Security
for the future “Green” city
