Section B Question 2Satellite communications
and LBS

• Why Satellite technology is better?
• Satellite signal, whilst having to penetrate the
  atmosphere, designed to be focused in the zone of
  delivery. Mobile signals propagate out from
  antenna just a few feet off the ground, they have
  much denser air to penetrate from the outset and
  of course the transmission frequency means the
  speed is less likely to be affected by the signal
  loss factors we considered at the beginning of
  the module
