The advent of mobile telecommunication has no doubt been an improvement in every facet of life as it has solved the nagging communication problems that have existed for decades especially in developing countries. It is an unparalleled fact that communication, effective communication is a veritable tool that ensures success in family, business, religion etc. when telephone was invented by Alexander Graham bell in 1874, the whole world was agog considering its awesome nature.

The world never knew that it was a tip of the iceberg when eventually mobile telecommunication was invented as a result of advanced researches on the work of Guglielmo Marconi (1874-1937), an Italian scientist that first proved that radio waves can travel across the Atlantic. Since then, the radio waves become the precursor that synthesizes other products of technological importance. It is as a result of this advancement in research that we have several other communication technologies that were branded uniquely some of these include; Bluetooth technology that works based on radio wave and other communication means that work based on emission and reception of radio wave. Mobile telecommunication is also identified in this light. Mobile telephony has actually been in existence in developed and some developing countries. It actually becomes operable in Nigeria when the license was approved for a telecommunication giant in the year 2001.

What followed was the erection of masts in the vicinities both commercial and residential areas. Urban areas especially are more much more involved as everywhere is dotted with high-rising masts belonging to one telecommunication giants or the other. Shortly after this period, there were raised eyebrows about the medical aftermath of these ‘death at alert’. It was reported that there are severe dangerous medical implications and side effects that are injurious to good health. It has been submitted that the telecommunication giant should have employed other means which are friendlier to health and environment than these masts which have been known to emit radiations that are carcinogenic. The reason there are less uproar as regards this in Nigeria, is because most people that live especially very closely to these masts are ignorant. They may not really understand the health implications.

It is therefore in my opinion that, the combined efforts of everyone in the society, coupled with that of appropriate regulatory bodies can help make the situation better. Individuals especially in developing countries like Nigeria should also be more enlightened that everything is not about money or business as usual! It is therefore high-time we stopped the telecommunication companies from giving us a paltry sum of money in exchange for our sound health. The question still remains rhetorically that, are there no other methods to provide these services apart from the masts?

History of Mobile Phones

The Electromagnet was invented in 1825 by William Sturgeon, a British electrician. This was followed by the invention of the electric telegraph by Samuel Morse that transmit electrical signal over wires and is translated to message. The Telephone, a device that could transmit speech electrically was invented by Alexander Graham Bell in 1876.

Radio technology began as wireless telegraphy in 1866 by Mahlon Loomis, an American dentist. The Radio, a two way communication device developed from the permanent installations in vehicles to bag phones and the backpacked walkie talkie developed by Motorola in 1940s to hand held two way Handie talkie (HT) It was the size of a man’s forearm.The telephone and Radio technologies combined to bring Radio Telephone.Radio telephone appeared in Europe in1926.

Soon, it was realized that when mobile phones are connected to smaller and lower powered base stations arranged in cellular pattern and with frequency reuse there is an increase in the number of people who can talk at a time i.e an increase in the traffic capacity.This was how the cellular phone started in 1947. The electronics of cell phones was developed by Richard H. Frenkiel and Joel S. Enjel of Bell lab in the 1960s.

Most phones were analog in the 1980s. They are mostly digital now with ease of signaling,lower level of interference and increased capacity.

GSM (Mobile System for Mobile communication)

Lack of standardization for the various systems developed resulted in compatibility problems especially with the development of Radio technology. To address this problems, GSM, a standardization group was established in 1982 to create a common European mobile telephone standard that would formulate specifications for a pan European mobile cellular Radio system. It was hoped then that other countries would join the partnership.

FURTHER DEVELOPMENTS.

1G (First generation) These were analog, used for voice calls only.

2G (Second generation):These were digital, provided caller identity, text messaging, avoid interference and drop calls and could handle a large number of calls.

2.5G Between 2G and 3G. Provided faster services than 2G and can access the internet.

3G Suitable for high speed data application, traditional voice calls, provide navigational maps, web browsing, fax, paging, email, video conferencing, multimedia, TV streaming.
