3G

By: Manasvi   Mehta
What is 3G?
• 3G is the third generation of wireless technologies.
  It comes with enhancements over previous wireless
  technologies, like high-speed
  transmission, advanced multimedia access and
  global roaming.
• 3G is mostly used with mobile phones and handsets
  as a means to connect the phone to the Internet or
  other IP networks in order to make voice and video
  calls, to download and upload data and to surf the
  net.
How 3G works?
• 3G-enabled devices – including phones and laptops
  – work by sending and receiving radio signals to and
  from base stations (sometimes known as ‘masts’).
  Base stations link individual phones into the rest of
  the mobile and landline networks.
• Base stations are low power radio transmitters and
  need to be located in the areas they are intended to
  serve. They provide coverage to a geographical area
  known as a cell. These cells need to overlap to
  enable seamless coverage and to ensure a user
  does not lose connection to the network when on
  the move.
Birth of 3G
• The first pre-commercial trial network with 3G was
  launched by NTT DoCoMo in Japan in the Tokyo
  region in May 2001. NTT DoCoMo launched the first
  commercial 3G network on October 1, 2001, using
  the WCDMA technology.

Faster & Better
What is next? 4G?
• Yes! 4G technology is the fourth level of wireless
  technology . The first generation of wireless
  technology available, 1G, refers to the analog signal
  used by cellular towers. 2G technology upgraded
  the analog signal to digital and allowed the inclusion
  of sending texts across the network. 3G technology
  made use of electromagnetic wavelengths, known
  as spectrum, to broadcast a wireless broadband
  signal that allowed users to access the Internet and
  download applications . 4G technology upgrades
  further to faster information transfer
  times, heightened security and greater information
  exchange abilities.
