2. Introduction
 An accurate and transparent attendance marking system is of
utmost importance in educational institutions as well as businesses.
 In today’s fast-moving world, the main drawback in traditional
attendance systems is its tediousness, and manual effort that the
user has to put in.
 This project will enable us to automate the process of marking
attendance of students in a college, using Wi-Fi Positioning
Systems.
 The primary motivation for this project is the need for automation
that would reduce the time and efforts required for this
monotonous job.

3. Problem Statement
 To create a system that can automate the process of
marking attendance by using the technology of Wi-Fi
Positioning System.
 To reduce human effort and increase efficiency of
attendance marking process and reduce chances of
fraudulent activities.

4. Existing Systems
 Traditional Roll Call & Manual Marking
 Mechanical Punch Clocks
 Time Cards
 Proximity Card
 Biometrics

5. Proposed System
 WiPAt removes all discrepancies of existing systems.
 This system is highly cost effective as compared to
magnetic card and biometric systems.
 The tedious manual effort in roll call system and
mechanical punch clock is reduced by full automation.

7. Key Concepts
1. Trilateration:
 Trilateration is the process
of determining relative
locations of a device by
measuring the radial
distance using the received
signal from three different
points.

8. 2. RSSI (dBm) :
 Received Signal Strength
Indicator is the measurement of
the power present in a received
radio signal. This strength is
represented in percentage or
dBm. The corresponding db
values can be easily converted
into distance.
 db = 0 db : 100% quality
db = -100 db : 0% quality
(approximately)

18. Applications of WiPAt
 Efficient attendance system in educational
institutions to analyze student attendance statistics.
 Fraud-proof attendance system in business offices
which will ensure higher employee productivity.

19. Benefits
 Reduced time and efforts
 Reduced errors
 Reduced costs
 Eliminates paperwork
 Increased productivity.
 Central database (easy
access)
 Decreased burden on one
person
 Increased security

20. Challenges
• Fraudulent practices may
still persist in minute
loopholes.
• Power supply for system
and routers needs to be
optimized.
• Device battery usage
optimization required.
• Feasibility issues on large
scale.

21. Future Scope
• Wi-Fi Positioning System is a technology with
tremendous scope for the future.
1. Device/Person Tracking
2. 3-D Positioning
3. Vehicle tracking
4. Crowd Handling
5. Augmented Reality
6. Improved GPS accuracy
7. Security and Theft Detection

22. Conclusion
• WiPAt is a very human friendly attendance system with
highly efficient technology and algorithms.
• This system, after a few feasibility tests, can be officially
used in colleges where traditional unproductive systems
are still in practice.
