Location based advertisement system with voice announcement system

1. Location based advertisement system with voice announcement system
Abstract
Aim:-the aim of the project to construct a system using GPS voice circuit that can
identify its current location and based on that it announces the advertisement
assigned for that location automatically. Also the project has a provision of
dynamically storing location along with the current location coordinates display
on LCD.
Location based advertising (LBA) is new form of marketing communication
that uses location tracking technology to target consumer with location specific
advertising on their mobile devices. LBA refers to market control information
specifically tailored for the place where user access an advertising medium,
imagine if a tourist is in Hyderabad with friends and are looking for a restaurant;
he can just use this device to locate the hotels in nearby location.
This project consist of location identification device called GPS receiver and
LCD for displaying the current location coordinates and voice based
advertisement. The GPS receiver gets the current location in the form of latitude
and longitude and this information is given to microcontroller. Microcontroller
process this data and compare the location information with the existing location
store. Upon finding the location in the database it make the voice based
advertisement triggered from voice circuit. The microcontroller is programmed
using embedded C language.
Introduction
Over the next few years there is likely to be a dramatic increase in services for the general public
which are based on knowing your location. A mobile phone handset is a device on which it will
be possible to request the location of the nearest place and be provided with alerts that we reach
that place.
The rapid advancements in information technology and wireless communication nowadays it is
very necessary for everyone to be updated about current affairs such as mobile phones, news,

2. stock markets, sporting events, etc. Mobile phones have been trend lately. Corporate as well as
Consumer products are increasingly geared towards mobility and Location Based Services. This
is where our study focuses on the ability of mobile devices which provides software solutions
which are location sensitive.
Location based services are information and entertainment services accessible with mobile
devices through mobile network and utilizing the ability to make use of the geographical position
of the mobile device. Mobile devices send and receive radio signals with any number of cell site
base stations fitted with microwave antennas. These sites are usually mounted on a tower, pole or
building, located throughout populated areas, then connected to a cabled communication network
and switching system.
Literature review
A Location-Based Service (LBS) is an information or entertainment service accessible with
mobile devices through the mobile network and utilizing the ability to make use of the
geographical position of the mobile device.
LBS can be used in a variety of contexts, such as health, indoor object search, entertainment,
work, personal life, etc.
LBS include services to identify a location of a person or object, such as discovering the nearest
banking cash machine or the whereabouts of a friend or employee. LBS include parcel tracking
and vehicle tracking services. LBS can include mobile commerce when taking the form of
coupons or advertising directed at customers based on their current location. They include
personalized weather services and even location-based games. They are an example of
telecommunication convergence.
Location-based services offer many opportunities. For the mobile user, some examples of
location-based services are
ion of a sale on gas or warning of a traffic jam.

3. A big advantage is that mobile users don't have to manually specify ZIP codes or other location
identifiers to use location-based services.
For the carrier, location-based services provide value add by enabling services such as
Resource tracking with dynamic distribution
Taxis, service people, rental equipment, doctors, fleet scheduling
Resource tracking
Objects without privacy controls, using passive sensors or RF tags, such as packages and train
boxcars
Finding someone or something
Person by skill (doctor), business directory, navigation, weather, traffic, room schedules, stolen
phone, emergency 911
Proximity based notification (push or pull)
Objective
The big problem in LBS system is to accurately find the position of the user. Here are some of
the traditional methods and locating methods.
GSM Localization
GSM localization is the second option. Finding the location of a mobile device in relation to its
cell site is another way to find out the location of an object or a person. It relies on various means
of multilateration of the signal from cell sites serving a mobile phone. The geographical position
of the device is found out through various techniques like time difference of arrival (TDOA) or
Enhanced Observed Time Difference (E-OTD).
Near LBS (NLBS)
Another example is Near LBS (NLBS), in which local-range technologies such as Bluetooth,
WLAN, infrared and/or RFID/Near Field Communication technologies are used to match
devices to nearby services. This application allows a person to access information based on their
surroundings; especially suitable for using inside closed premises, restricted/ regional areas.
Control Plane Locating
Sometimes referred to as positioning, with control plane locating the service provider gets the
location based on the radio signal delay of the closest cell-phone towers (for phones without GPS
features) which can be quite slow as it uses the 'voice control' channel. In the UK, networks do
not use trilateration; LBS services use a single base station, with a 'radius' of inaccuracy, to
determine a phone's location. This technique was the basis of the E-911 mandate and is still used

4. to locate cellphones as a safety measure. Newer phones and PDAs typically have an integrated
A-GPS chip.
In order to provide a successful LBS technology the following factors must be met:
dinates accuracy requirements that are determined by the relevant service;
Methodology
This project consist of location identification device called GPS receiver and LCD
for displaying the current location coordinates and voice based advertisement.
The GPS receiver gets the current location in the form of latitude and longitude
and this information is given to microcontroller. Microcontroller process this data
and compare the location information with the existing location store. Upon
finding the location in the database it make the voice based advertisement
triggered from voice circuit. The microcontroller is programmed using embedded
C language

7. 3) LCD
LCD (Liquid Crystal Display) screen is an electronic display module and find a wide range of applications.
A 16x2 LCD display is very basic module and is very commonly used in various devices and circuits.
These modules are preferred over seven segments and other multi segment LEDs. The reasons being:
LCDs are economical; easily programmable; have no limitation of displaying special & even custom
characters (unlike in seven segments), animations and so on.
A 16x2 LCD means it can display 16 characters per line and there are 2 such lines. In this LCD each
character is displayed in 5x7 pixel matrix. This LCD has two registers, namely, Command and Data.
The command register stores the command instructions given to the LCD. A command is an instruction
given to LCD to do a predefined task like initializing it, clearing its screen, setting the cursor position,
controlling display etc. The data register stores the data to be displayed on the LCD. The data is the
ASCII value of the character to be displayed on the LCD. Click to learn more about internal structure of

GPS
1) The Global Positioning System (GPS) is a U.S. owned utility. It provides users with
positioning, navigation, and timing (PNT) services. The Global Positioning System
(GPS) is actually a constellation of 27 Earth-orbiting satellites (24 in operation and
three extras in case one fails).The orbits are arranged so that at anytime, anywhere on
Earth, there are at least four satellites "visible" in the sky.A GPS receiver's job is to
locate four or more of these satellites, figure out the distance to each, and use this
information to deduce its own location.
2) Working of GPS
3)

9. 4) Global Positioning System satellites transmit signals to equipment on the ground. GPS
receivers passively receive satellite signals; they do not transmit. GPS receivers require
an unobstructed view of the sky, so they are used only outdoors and they often do not
perform well within forested areas or near tall buildings. GPS operations depend on a
very accurate time reference, which is provided by atomic clocks at the U.S. Naval
Observatory. Each GPS satellite has atomic clocks on board.
5) A GPS receiver "knows" the location of the satellites, because that information is
included in satellite transmissions. By estimating how far away a satellite is, the
receiver also "knows" it is located somewhere on the surface of an imaginary sphere
centered at the satellite. It then determines the sizes of several spheres, one for each
satellite. The receiver is located where these spheres intersect.
6) Latitude & Longitude
