Cellular technology is one of the fastest and on going growing telecommunication industry of the world; it may easily be one of those industries which may never suffer from economics of the world. Even today millions of users are subscribing to different mobile networks in the world.
There are numerous mobile communication technologies which makes growth of cellular industry to this extend one of the technology which is by far the best and most widely used in mobile communication is GSM, GSM stands for Global System for Mobile Communications.
Old Mobile Communication Technologies.
Early in 1980’s there were few mobile communication technologies like AMPS, Advance Mobile Phone Service, TACS, Total Access Communication Systems and NMT, Nordic Mobile Technology. AMPS were widely used in North America which was later adopted by many other countries world wide. TACS was deployed in United kingdom where as NMT was implemented in Nordic countries.
Evolution of Mobile Communication Technologies
Communication technologies mentioned above had many limitations which had to be over come for the growth of the industry. Each country had deployed their own set of standards for communications which was making impossible to go beyond boundaries. All the systems and services were limited with in the country in which system is deployed and no services were available to be hired from even neighbored countries. Do you this problem mobile equipment manufactures markets were limited to the operating system and no hardware was compatible to the OS of other communication technologies. Because of these limitations and boundaries communication for longer distances were either impossible or were very expensive, there were no concepts of International roaming do you limitations of the systems, no international calls were possible using these technologies.
Unlike today, in back days telephonic systems were analog, the biggest challenge faced by analog systems was inability to cope with the growing needs of telecommunication industry with cost efficiency. This challenge brought evolution in this industry and need for digital technology was realized. In result to introduction of digital communication over analog system better receptions of signals were experienced, low level of interference, integration, transmission, switching and improved levels to meet the needs of current telecommunication industry challenges.
Mobile Internet Communication Technologies
There are number of mobile communication technologies which have been developed ever since from analog days,, every now and then new technology is released to cope with telephonic industry demands. Currently we have following mobile and internet communication technologies adopted by different mobile companies in different parts of the world.
