Conclusion  
Introduction:


  “Mobile phone” a common sound now a day in our life and a hidden thread for our life 

which about we are really unconscious and careless. Now a days mobile phone become a part of 

fashion. By this way consciously or unconsciously we destroy ourselves. We will shocked if we 

heard that a cell phone can destroy our brain, badly damaged our heart, can destroy our family 

happiness, destroy our social status. Cell phone is just like rats which destroy the home where it 

lives. But it’s very important that we need to think about mobile phone for second time. 

   
  Cell phone is a radioactive device. Base-station and a mobile phone always radiate radiation  

and some of the radio frequency is responsible for skin cancer. Cell phone technology uses 

smaller wave length’s frequencies and which frequency is so high and this type of high 

frequency can cause heart attack. Widespread use of cell phone is having several negative effects

on our society in the physical, mental, economical and social level.


  For the availability of cell phone any one can buy a cell phone whether he or she needs it or  

not. That’s why communication with each other has become so easier and phone friendship, 

phone affair (Relationship between a girl and boy), extra marital affair has become common in 

the society life. And result of this type of phone relationship or mobile relationship is very 

dangerous and sometimes it can take one’s life. Mobile phone is creating unstable, unreliable, 

and problematic social relationship. For the criminal’s cell phone is a bless of god because the 

communication with the gang members has become easier. Threats through mobile phone has 

now become very common.


  We are familiar with the idea of sound teasing girls through mobile phone. To protect our 

women society from the disturbance of unwanted mobile calls our cell phone service providers 

are promoting new services with new style with new business policy that is so called “call block”

service. It’s really a big social problem for us but we are totally unconcerned about it. The cell 

phone service providers are showing that they are doing lots of social works and if they can they 

will sacrifice themselves for mankind but they are creating a social problem and they are totally 

careless about it. Not only that but also they are doing business with this self creating social 

problem. And this type of service is too much expensive with respect to our economical status. 

And they affect us economically. From the above statement we can say that they are so selfish 

and they can do anything for their profit. And they hide the information that cell phone 

radiation is adversely affects our health. Even though cell phone has many advantages but we 

have to think about the disadvantages otherwise we will loose a peaceful society.
Cell phone & how its works :


  Cell phone is radio frequency device and it is also responsible for radiation. It’s a 

wireless system and it is use various frequencies to communicate. Frequencies are responsible 

for radiation and microwave oven is example of this type of radiation.





BASIC COMPONENT OF MOBILE PHONE :



1. Mobile station(MS)

2. base station or access point(BS=BTS+BSC)

3. mobile switching center (MSC)


 
Picture 1 : basic diagram of cell phone system.


FREQUENCY USED BY CELL PHONE SYSTEM :


  The radio spectrum, 3 KHz- 300 GHz, is divided into eight frequency bands, from VLF 

(Very Low Frequency) to EHF (Extremely High Frequency) . Low frequencies bounce on the 

earth surface and in the atmosphere and can reach very far – to other countries or continents. 

High frequencies, above ~ 3 GHz are sensitive to shadowing and need line of sight (compare 

with radio links). The cellular systems use frequencies around 1 GHz in the UHF (Ultra High 

Frequency) band and that is high enough to get the right cell size and low enough to have 

frequencies that can go through and bounce on buildings.

Physical effects of cell phone :


Effects on brain :


  A cell phone radiation is very dangerous and it can cook your brain within 65 minute and it is 

proved by two russian journalist. Vladimir Lagovski and Andrei Moiseynko from 

Komsomolskaya Pravda Newspaper in Moscow decided to learn first-hand how harmful cell 

phones are. There is no magic in cooking with your cell phone. The secret is in the radio waves

that the cell phone radiates.

The journalist created a simple microwave structure as shown in the picture.

  They called from one cell phone to the other and both phones are on talking mode. They 

placed a tape recorder next to phones to imitate sounds of speaking so the phones would stay 

on . 

After,

15 minutes: The egg became slightly warm.

25 minutes: The egg became very warm.

40 minutes: The egg became very hot.

65 minutes: The egg was cooked. (As you can see.)

Effects on body :


  Cell Phones use electromagnetic radiation(EMR) in the microwave range, which is depending 

on the cell phone network system (i.e. CDMA, GSM, 3G, TDMA, etc.). Some cell phone 

transmit a regular transmission for polling information to the nearest cell site. In this case, we 

would be getting exposed to some low level radiation. 


  Mobile phones transmit using radio frequency radiation (RFR). It is Depending on the 

network this can range between 800MHz and 3GHz. These are radio frequencies located within 

the electromagnetic spectrum. X-rays which are known to cause cancer and ionizing radiation are 

also within the electromagnetic spectrum and some researchers believe this should be harmful to 

human health.


  Cell phone uses microwave to communicate with base station to mobile switching center. 

These microwave is used to cook food e.g. Microwave oven. It’s true that in our city base 

stations are situated on our top of the building i.e. on our head. Those base stations are harmful 

and harming us just likes slow poisoning. The thing to keep in mind is that radio frequency (RF) 

transmissions are dangerous. it is well documented that high levels of RF are DANGEROUS! 

Cell phones transmit at much lower energy levels, but their consistent and prolonged use may 

well have a cumulative effect. High levels of RFR can cause health effects through heating the

human body (thermal effects), resulting in headaches and possibly other symptoms.


  Economical effect of cell phone :


  Economically cell phone affects us in two way directly and indirectly. The cell phone service 

provider make mobile phone and SIM card price cheaper and call rate is highest. People buy a 

cell phone because of cheapest price but when one buy a mobile then he is fallen in trap and

he is starting calling and chatting and unconsciously invite an extra cost. 
   

  The profit of cell phone service provider companies is too much. Grameen phone earn  

revenue 5440 core for year 2008. it is really big amount in respect to our economical status. And 

we just use this large amount of money only for talking. It’s true that we are unconsciously 

wasting our money.













Social effects of cell phone :


Effects on human behavior :



  Cell phone is dramatically affects our behavior. Slowly it changes our daily life’s common 

attitudes. Sometime its makes us lire. And it is really a common scenery for us that lying through 

cell phone. Sometimes I m also utilize this beneficial use of cell phone. For example if any one 

get money from the x and calling x for asking money. Person x will receive the call but he will 

lie if he has no money. Person x will say that I m not at home or I m very far from home even 

though he is at home. Now I narrate a true story one of friends. One day we all fix a program that 

we all go for out of Dhaka for a day. One of my friends said that he won’t be able to go with us 

because of sickness. All of we feel very sorrow for him and we cancel our tour and we decide to 

go to his home. After reaching at his home we were really shocked that he was quite well and he 

was lying because he had fixed a date with his girl friend. He says than his girl friend makes this 

date last night suddenly that’s why he was lie through mobile phone. Its true that a mobile phone 

is useful device but it makes us lire. We know that “lie is mother of evil”. But this mobile phone 

makes us lire unconsciously. Sometimes boy friend is telling lie with his girl friend through 

mobile phone and girls are also telling lie with her boy friend. It is happening because we can’t 

judge truth through mobile phone. And I have seen a drama where the writer show how and 

when a boy saying lie with his girlfriend. (Houseful)






Criminal activities:


  Mobile phone is a bless for the criminals. Mobile phone make the whole world in our hand. It 

makes the large distance a little one. And that’s why criminals can communicate with their gang 

members easily and they don’t need to take any risk to meet with all the gang members. And

we heard that criminals are continuing their criminal activities from abroad through mobile

phone. They threat the businessman or their target through mobile phone to pay them large

amount of money. I have seen it one of the daily news paper. I have really shocked that the cell

phone operator are not careful about this criminal activities. I have get this information from a

CNG owner MR RIJVI AHMMED, he said that when a CNG is theft then the thief demand large

amount of money to return the CNG but the money should have to pay through mobile phone i.e.

“Flexi load” (MR RIJVI AHMMED. Personal interview. 3 august 2009). The thief demand

money and get money safely through mobile phone but the cell phone service provider doesn’t

take any step to stop this type of criminal activities. But if they wish they can help the police to

catch the criminals within few minutes but they are not as much helpful as much they have to be.

They think about their profit and if a number is active then they will get some money through

this number. This problem is occurred because of availability of cell phone i.e. selling SIM card

without authorized identification. The cell phone service provider is not aware for registering the

SIM card and the government is also careless to apply the rules properly. When the police are

trying to identify the culprit they can’t because of unauthorized or invalid registration. Any one

can buy a cell number without providing any proper identification papers.






Negative Effects on girls :


   
  Mobile phone is creating a new way of disturbing the girls. All of us familiar with that teasing 

girls through mobile phone. Some naughty boys are creating this problem with the help of cell 

phone. Those boys get lots of fun by doing this nasty work. Sometimes girls are threaten by the

 naughty boys when a girl refuse a boy to become his valentine. Then the boy just collects her

cell number and spread it to others and all of us know the other scenery. Mobile phone is 

essential for communication but it is really creating a social problem for the girls.


  We are familiar with the idea of teasing girls through mobile phone and the cell phone service 

provider use this idea for business purpose. To protect our women society from the disturbance 

of unwanted mobile calls our cell phone service providers are promoting new services with new 

style with new business policy that is so called “CALL BLOCK” service. It’s really a big social 

problem for us but we are totally unconcerned about it. The cell phone service provider is just 

doing business and don’t cordial about this problem. They can terminate the cell number and 

warn the owner of the cell number to do not disturb any one again. By this action the bad guys 

will be careful and afraid to do this type of nasty disturbance. The cell phone service providers

are showing that they are doing lots of social works and if they can they will sacrifice

themselves for mankind but they are creating a social problem and they are totally careless about 

it. Not only that but also they are doing business with this social problem. And this type of 

service is too much expensive with respect to our economical status. And they affect us 

economically. From the above statement we can say that they are so selfish and they can do 

anything for their profit. And they hide the information that cell phone radiation is adversely 



affects our health. Even though cell phone has many advantages but we have to think about the 

disadvantages otherwise we will loose a peaceful society.


Creation of undesirable relationship between opposite sexes :


   
  Mobile phone is also responsible for creating extra marital affairs. When a married man or 

woman feel lonely then they want do something that will remove their loneliness. Some times 

they start talking with unknown to remove their loneliness. And after that they become friend 

and then they fallen in love with each other. And it is also true for all unmarried boys and girls. 

Educated and uneducated both societies are victim of this social problem. The cell phone service

providers are promoting new services e.g. “mobile chat” where any one will get new friends and 

this service is too much expensive. Any one can be cheated through this service. Sometimes 

frauds are putting their names to trap a girl or a boy. And I was shocked by seeing this news in 

“The Daily Ittefaq” that a doctor was killed by her boyfriend and she knew that boy through cell 

phone. At first they were unknown and then they became friend without meeting with each 

other and then they fallen in love with each other without seeing or knowing each other properly 

just depending on chatting through mobile phone. And at last the boy killed the girl. So think 

how dangerous it is? There is no advertisement or proper actions to protest this social problem. 

And that’s why this type of problems are increasing. Everyone should active to protest this 

problem specially the government, the social affair organizations and the cell phone service 

providers.


Conclusion :




  Sometimes the essential thing can be harmful for us same as cell phone and we cant go 

without it but we have to be careful about its harmful effects. . From the above discussion we can  

say that service providers are so selfish and they can do anything for their profit. And they hide 

the information that cell phone radiation is adversely affects our health. Even though cell phone 

has many advantages but we have to think about the disadvantages otherwise we will loose a 

peaceful society. Everyone should active to protect this problem specially the government, the 

social affair organizations and the cell phone service providers. We have to think about cell 

phone for second time. We have to be more careful because it is a hidden threat for our life and

for our society.
