  1. Cellular Networks: Past, Present, and Future • This article discusses the history, present state, and future of cellular radio networks. • some examples of mobile communication systems currently in use are: • Paging • Communication Satellites • Cellular Radio Networks • Personal Handy Phone • Mobile Radio

  2. History of Cellular • In 1946, the first car-based telephone was set up in St. Louis, Missouri, USA. • This used a half duplex system. • In the 1960s, the system was improved to a two-channel system, called the improved mobile telephone system (IMTS)

  3. Present Day • Cellular radio is the fastest growing segment of the communications industry. • Current cellular radio systems are in their second generation (2G). • The third generation of cellular systems (3G systems) will allow different systems to interoperate in order to attain global roaming across different cellular radio networks.

  4. How does it work • A cellular telephone or any other device that can connect to a cellular radio network will be referred to as a mobile station. • A cellular network consists of both land and radio based sections. Such a network is commonly referred to as a PLMN - public land mobile network.

  5. A cellular System

  6. Other explanations • The site also explains about protocols used ,Radio Resource management, mobility management, communication management and also radio link overview. • It gives all the details with appropriate figures.

  7. The Future • Cellular networks are incrementally upgraded to provide better data transmission capabilities. • Cellular networks are becoming high speed data networks. • Industry is working on speeding up the development of mobile communication technologies. The ideal communication system where both voice and data services can be delivered regardless of location, network, or terminal may be in the near future.

  8. Relationship to Networking • Cellular phones are one of the mostly used networking systems to communicate with other people from any place and it uses all the networking devices like protocols etc for transmitting the messages from one end to the other.

  9. About the site • This site overall provides minute details about how the cellular phone started and how it is at present and how it will be in future. Also it gives minute details about the messages are transmitted from one end to the other. It also gives some of the useful links to have better information regarding this.

  10. Cellular Phone-Use • Cellular phone is used by any person to communicate with each other and this is mostly used device which is easy to keep track of about the people and also used to communicate the important messages and also mostly used by business people even during the journey.So it makes life easy for people as they can communicate even though they are traveling.

  11. Conclusion • Thus this has given the basic information about mobile phones and how they will be in future. • Some other sites that gives more information are: • http://www.doc.ic.ac.uk/~nd/surprise_96/journal/vol4/vk5/report.html • http://web.media.mit.edu/~niloy/bookmark.html
