Mobile Technology

 

    Over the years we have seen that Mobiles have became an indispensible part our life.

    Starting from  general mobile  function such as calling and ending messages it has

    also played an important role in humans life of staying updated about latest news with

    one click using Touchscreen, Paying daily household bills, watching videos, 

    listening to songs , making videos and more

   In this article we are going to  understand about Mobile Technology and its different

   features.

 

  What is Mobile  Technology ? 

   Mobile Technology  is a  type of electronic portable  device which is used for

   cellular  communications, send and receive  messages, access social media

   platforms,discover  places  and  information, entertainment,shopping etc

   Mobile technology consists of  portable  two  way  communication device,

   computing  device and  the  networking  technology  that  connects them  

   Some of Mobile technology  devices  are  as  follows:

      1. Laptops and Tablets

      2. Smartphones

      3  Global  Positioning  Devices 

   

  Platforms on which Mobile Technology is based!

   There  are  two very Basic Technologies   on which Mobile Technology:

     GSM: Global System for Mobile Communications

     CDMA: Code Divison Multiple Access

   so let us undertsand in detail about GSM and CDMA:

     GSM: GSM or Global System for Mobile Communications  main characteristics

                 is that its is SIM specific meaning that the phone number si linked to the 

                 SIM card  so when you are switching the device all you need to do  is 

                 fetch out the SIM card and insert it into another device.    

                 All the information of the user are embedded in the  SIM card which 

                 the user is using 

                 The GSM association is an International association founded in 1987

                 with the goal  of developing and extending the GSM wireless standard.

                 GSM network uses TDMA(Time Division Multiple Access Technology)

                 which assigns time slots to multiple    conversations teams.alternating

                 them is sequence and  and switching between each conversations in

                 very small time slots.

                 Almost 80  -90%  of the world  populations  uses  GSM .It has

                 roaming accessibilities and uses GPRS which provides lower bandwidth

 

     CDMA: CDMA or  Code Division Multiple access  is a handset based standard

                   with a phone number linked to the specific device.if  you want  to 

                   upgrade with a another phone you would have to get in touch with

                   network carrier , de activate the old device and activate the new one.

                   CDMA networks layer digitized call over  one another, assigning unique

                   codes to differentiate  between them.Every call data is enclosed  with a 

                    different key and the calls are then transmitted at the same time.

                    each receiver have a unique key to  split the combined signals into

                    unique call.

                    CDMA uses EVDO which provides higher data bandwidth hence it has

                    faster transmission rate.

 

       GSM and CDMA are both  unique technologies. GSM technologies forms the basis 

       of 2G mobile phones whereas CDMA technology forms the basis for 3G mobile

       phones. Its upon the discretion of the user to use either GSM or CDMA.
