Abstract
Description
Since the introduction of cellular analogue phone in 1985 (first generation mobile phone),
there has been a continuous improvement from the first generation to digital secondgeneration
to 2.5 generation and now the third-generation. The ground is also being
prepared for the fourth-generation mobile phone. Mobile technology has transformed our
lives in ways that might have seemed unimaginable some years ago and yet we are still
witnessing more transformations and many more are yet to come. This paper examines the
concept of cellular communication, the development of mobile phones, the features in the
past, the current trends and what to the future holds in general and specifically for Nigeria.
The cost implications of the various generations over the previous ones to the end users are
also discussed
