Radios are Everywhere

Radio signals are used in a huge variety of applications.  In fact the radio spectrum, which starts at only 500kHz extends to almost 500 GHz and is completley filled with different services.  Things from submarine to satellite communications; mobile phone to wireless broadcasts, clothing tabs to aircraft navigation, all use the radio spectrum.  We use these services every day, maybe without fully realising the challenges that are overcome to deliver them. 

Also, in recent year the advent of digital technology has triggered a revolution in the design of radio systems, opening up new posssibilities for cooperation, communications and control in an even wider range of applicaitons. So if you think that radio systems is an established technology, think again.  It has in fact never been more dynamic and revolutionary.  It is the key in much of the technological innovation that is driving the modern economy and the experienced staff at RSD have lived through and gained experience from this tremendous revolution..

Consider that the number of radio receivers and particularly transmitters has mushroomed in recent years.  Forty years ago most people owned a few radio recievers and only governements and big organisations used transmitters.  In contrast,  today most people own more than 10 transmitters and receivers each.  If that seems an exageration, take a moment to think about it.  Remember, not just the 1 or 2 traditional broadcast radio and television receivers in the house; it includes phones, wifi and bluetooth as well. There are radios are in cars, there are 2 or 3 in each mobile phone as well as each wireless router,  laptop computer and tablet. Then consider the ever growing number of 'things'  that now include radio connectivity,  digital assistants, streaming audio devices, car and home security systems and more.  if you have been counting your devices, 10 is almost certainly an underestimate!
