What Happens If There Ever Mobile ChickMobile , the most common gadget in the present era , regarded as the greatest gift to mankind . Can you ever imagine a life without this device ? No wonder if the cell phone has become an indispensable part of our lives .Of course , the origin of this interesting gadget use. Ranging
from large devices such as arm length and weight of a person for an
ultra- thin handset and techno -savvy , mobile phones have certainly
covered much so far .Well , the idea of finding the phone and how it was created ? To get answers to these questions , we need to travel back over a century !Origins - Telephone and Radio CommunicationAlexander Graham Bell - 1876Obviously , it all starts with basic telephony . In 1876 , Alexander Graham Bell was the first to patent the telephone technology . Phone technology that may be developed by using equipment that is really designed for the telegraph .Where when you want the call to be connected with the help of a designated operator .The
first pillar of the mobile phone is supported when Charles Stevenson
creates radio communications in the early 1890s for communication with
offshore lighthouse . After that , Marconi succeeded in sending a signal over a distance of 2 km in 1894 .Phone calls without Cables - A successful foundation embodied wireless phone .Reginald Fessenden - 1900It
was on December 23, 1900 , on the outskirts of Washington DC , Reginald
Fessenden accomplished a feat that is worthy of note : He made the
first wireless phone to transmit the human voice over the radio waves
transmit radio signals from one tower to another tower .In this way provide a strong foundation for the concept of mobile and radio networks . In 1906 , Fessenden 's first music broadcast over the radio .Merging Technologies Phone Radio - 1908Although
mobile phones can be seen as a new technology these days , the idea was
actually first conceived in 1908 , said that because the phone is
actually a high-tech radio .In 1908 , a man named Nathan B. Stubblefield
who live in Murray , Kentucky to apply U.S. Patent 887,357 for a
wireless phone , she actually apply only to telephone the radio patent .
However , by doing this , it is only intended to create a phone that can operate with a data set .It was in 1926 that connects the Executive Trains Berlin and Hamburg using a radio telephone technology for the first time . Radio telephone is also used in aircraft and for the safety of air traffic . In addition, the German tanks utilize these devices during the Second World War .Dau band radio is the ancestor of the phone . They are also known as mobile rigs and fixed on a police car , taxi , and ambulance before the invention of cell phones . As a mobile radio that is connected to the telephone network , one can not call directly to another radio . Gradually, the technology is gaining immense popularity among the mobile radio users .The new version of the mobile radio has been entered for cigarette lighters and is known as the cell phone bag . The gadget is still in the vehicle and used as a portable two-way radio .The presence of Walkie Talkie - 1940In 1940 , Motorola came up with new developments in radio and as a result of two -way , walkie talkie born . Big, bold and operated by Battrey , but this device soon find its way to be used in the U.S. military .Interventions of Sound Mobile Theory - 1947A major breakthrough in the history of mobile phones when it comes to mobile phone base station appears . In
1947 , engineers from Bell Laboratories , which is part of AT & T
at that time , to develop base stations for mobile phones . In the same year , William Rae Young and Douglas H. Ring of hexagonal cells develop for this phone . But an engineer , Porter of Bell Labs , proposed cell tower at the corner position hexagon , not the center . He
also argues for a directional antenna for transmitting or receiving
signals in three directions , namely , into the adjacent hexagon cells .The proposed design allows for a low-power transmitter to carry calls across the network . In
addition when a caller moves from one tower to broadcast radius of
another without any interruption and assistance from the operator . However , although the theory has been illustrated , the technology to make it happen less . It is estimated that it would take more than 10 years for the development of next !Use of Radio Telephone By Civil SocietyWhen
the world is waiting eagerly for further developments in mobile
technology , companies such as AT & T gives some customers the
opportunity to use the radio telephone .But
only a couple of calls that can be performed on the system at a time ,
the caller must wait for another conversation to be able to make calls
and the main disadvantage is that it may not have a private conversation
.In addition , the phone is too expensive and weighs up to 80 pounds ! Obviously , it was very expensive at that time .MTA - Automated Phone Systems - 1956In
1956 , the Company successfully spawned Ericsson's first cellular
telephone system is completely automatic called the MTA in Sweden . The device is operated automatically , however , because of the weight , he failed to defend the interests of the old user .Well , of course people will not be interested - it weighs 40 kg ! Then in 1965 , an upgraded and lighter version of the same phone introduced . This is known as MTB and menggunakansinyal DTMF .Wearable Mobile Phones - 1957Kupriyanovich Leonid , a Russian engineer , developed the experimental model of wearable mobile phone in Moscow in 1957 . The device is operated with the help of a base station . Kupriyanovich has previously developed - LK 1 , a radio telephone .The battery life of mobile wearable created lasted for nearly 20-30 hours . It weighs about 3 pounds and working within 20 to 30 km from the base station . In
the same year , a young engineer patented mobile phone and comes with
pocket versions of the phone that weighs only 0.5 kg , the weight is
still too time broo ..Further developments in the field of Mobile - 1967In 1966 , an automated phone called RAT - 0.5 was developed in Bulgaria .1967 to witness further developments in the field of mobile phones . From there later on decided that every mobile phone will be served by one station ( provider ) forever .Then in 1970 , another engineer named E. Ames Joel created automatically call hand -operated technology - off . This allows phones that are in the area covered can make a call without losing the conversation . This is probably the first time when a mobile user can use the device without any interruption and without operator assistance .Birth of Mobile Portable - 1960In 1960 , Bell Labs developed a technology that can support the design of mobile networks proposed by Young . However
, AT & T requested permission from the Federal Communications
Commission , FCC , to develop a mobile network in 1971 . They are trying to win the competition in 1973 with their competitors .The competitor is Martin Cooper who is an executive with Motorola . Cooper led a team that designed the first practical mobile phone , resembles the one that we use today .This
is known as the Motorola DynaTAC , a small device : that is 9 inches
long , 5 inches wide and weighs 2.5 ponds and contains approximately 30
circuit board in it . With
a charging time of about 10 hours , 35 minutes of talk time , the phone
gives a comfortable experience for the user speaks .We could dial , listen and talk on the phone , but the one thing missing - Screen !Cooper decided to make the first cell phone call that professional rival Joel Engel, Bell Labs .
Zero Generation Mobile Network - long before there is a 3G and 4GAnother important development in the history of the mobile phone has been registered with the successful launch ARP network in Finland . Perhaps , it is the beginning of a commercial mobile phone and the mobile network is known as the Zero Generation .Evolution of Mobile PhonesLike the days went by , more and more innovations are made and mobile technologies is rapidly increasing . With the introduction of the Global System for Mobile communications , the radio spectrum can be used effectively .This technology provides good sound quality and international roaming facilities combined with compatibility with the ISDN system .Fore , to cover remote areas where ISDN , GSM and mobile phones can not offer , a satellite phone is introduced . And stations for satellite phones built geostationary satellites . And this time , there is no place on the planet that is untouched by phone .Overall, the phone is very sophisticated radio and if not for the constant effort and progress for more than a century , this technology would not exist .Whatever we send with any sophisticated OS , with the latest series though phone is just a radio .
