This document discusses recent advances in communication technology, including GPS, Google Maps, ad hoc wireless networking for vehicles, car communities to share traffic information, localized car navigation systems, using radio signals to track stolen vehicles, and naval communication systems. The key advantages are more accurate positioning, real-time traffic updates, emergency response coordination, location-based services on the road, and secure naval communications. Future communication may involve controlling devices with eye movements or even just thinking.

2. INTRODUCTION
“Passing information from one to another and
understanding each other is called
Communication”.
Alexandra Graham Bell the method of
communication technology has developed at
an alarming rate.

3. Communication Development
 Telephone
 Television
 Internet(3G&4G)
 Satellite

4. General positioning system
The latest communication system is “General
positioning system”.
It shows an individual position with pinpoint
accuracy
It shows the directions
Understand the movement of the Earth itself.
Also understand when earthquake might
happen.

5. Google Maps
Google maps provides panoramic views
from position along many streets in the world.

6. Google map…
 It shows your position.
 To get directions from one place to other place.
 In the driving situation, it shows approximation
path.
 It also shows the paths in river.

7. Ad Hoc Wireless Networking Technology
This communication technology used
to communicate vehicles .Attention is now
focused on cars that “talk” and cars that “warn”.
This is very usefull to control traffic and
accidents.

8. Car Communities
 Multiple police cars can form a community.
 Similarly ambulances rushing to a tragic site
could also form an community.
 And also fire-engines.

9. Localized ITS car navigation
 To achieve a driving safety and comfort.
 Drivers on the highway is the need to change few lanes on the
higher prior to exit.

10. Essential elements here are
 Speed
 Distance from the existing point
 Which lane the car is currently residing
 Density of neighboring cars and their speed…
etc
By detecting the presence and speed of
neighboring vehicles in the localized region

11. Car traffic flow and congestion control
When an earthquake occurred and a part
of highway was broken on coming vehicles would
be put to halt.
The alert information hop-to-hop back to vehicles.

12. Traffic control….
After being information such vehicles should
slow down and might seek alternate routes to exit the
highway.
So as to avoid further traffic congestion.

13. ITS Ad Hoc service Architecture
This could allow vehicles to pickup
information concerning services available at
shop and retails that are located along the roads
and highways.

14. Service architecture….
Vehicles can still received the
advertised information.
The advantages here include the real
time propagation of sales and services
information and ability to locate the shop
quickly.

15. Localized tracking of stolen cars
In Japan that vehicles will be equipped
with some embedded device. That will emit a
unique and register identifier.
In this way the local police station can
be alerted, it also simplify the work of the local
police.

16. Digital Software Radio

17. Software defined radio….
 This enables the subsequent additions of new
wave forms or functions via software download.
 This can allows e-mails, faxes or TCP/IP service
on the internet or in military intranet via radio.

18. NAVAL communication
Now a days secure and protected radio
communication especially at sea are more
important than ever.

19. NAVAL communication….
This is protected against data loss
and ensures 100% redundancy as well as
secure and error-free storage of all
information.

20. Another advantages
 Movie from satellite
 Satellite television
 Control to things in your home
 Fast and free transitions

21. Conclusion
The way of developing
communication technology methods and ways
might change and expand in way the we never
thought possible.
In future , only movement of
hands, eyes and even by just thinking it.
