 ly automated mobile phone system for vehicles had been launched in Sweden 
 by TeliaSonera and Ericsson in 1956. Named MTA (Mobile Telephone system A)
 . This was the first time calls could be made and received in the car whil
 e using the public telephone network. Before 1973\, mobile telephones were
  limited to phones installed in cars and other vehicles.\n\nIn 1947\, an e
 ngineer at Bell Labs named William Rae Young proposed that radio towers ar
 ranged in a hexagonal pattern could support a telephone network. Young wor
 ked under another engineer named D.H. Ring. Young's design allowed for low
 -power transmitters to carry calls across the network. It also accounted f
 or handoffs\, which is when a caller moves from one tower's broadcast radi
 us to another. But though the theory was sound\, the technology to make it
  happen was lacking. It would take more than 10 years for the next develop
 ment.\n\nBy the 1960s\, Bell Labs engineers Richard Frenkiel and Joel Enge
 l developed the technology to support Young's design of a cellular network
 . But as AT&T sought permission from the Federal Communications Commission
  (FCC) to develop a cellular network\, Motorola (their competitor) made th
 e bold move in 1973 of making the first cellular based phone call.\n\nBy 1
 981\, the first generation of mobile telephone systems known as Nordic Mob
 ile Telephone System emerged in Sweden and Norway. Osten Makitalo\, who is
  know as the father of the mobile telephone\, said “NMT was the first mode
 rn telephone system\, the mother of all mobile telephones. Everything afte
 r that are actually just copies.” Initial NMT phones were designed to moun
 t in the trunk of a car\, with a keyboard/display unit at the drivers seat
 . \n\nAlthough Cooper and his colleagues had filed a patent for a 'radio t
 elephone system' in October of 1973\, the DynaTAC 8000X phone did not beco

 le telephone that could connect to the telephone network without the assis
 tance of a mobile operator and was portable for the user to carry about.  
 It cost about $4\,000 to purchase.\n
