Mobile phones can either be a blessing or a curse; this is determined by the way in which they are used. Since the late 1990's there has been an increasing amount of concern over whether mobile phones can cause some types of cancer or infertility in men. The first mobile phone was invented by the American scientist, Martin Cooper, in 1973. Martin Cooper was an executive and researcher at Motorola who are today a major mobile phone producing company. The design of the first mobile phone was very different to the way the mobile phones of today look and operate. Mobile phones were introduced into society in the mid 1980's in parts of Northern Europe. Countries such as Finland and Switzerland, Japan and the USA launched the first cellular networks which meant that any mobile phone connected to that network could communicate with each other. Now, nearly all countries are connected to at least one network, such as O2, Orange or Vodafone. This means that two mobile phones, for example one in the UK and one in Hong Kong, can wirelessly communicate with each other by sending and receiving radio signals to and from each other via a network. ..
