    Evaluation of Mobile Communications in a Predominantly Rocky Area
    (IEC Annual Review of Communications, 2007) Odinma, A. C.; Anyanwu, A. M.; Adelabu, M. A. K.
    Mobile communication in Nigeria is plagued with unprecedented dropped calls, crosstalk, and service unavailability even when the subscribers are credit-worthy. The reasons for such reprehensible observations are either due to natural causes, inadequate network infrastructure, or poor network design parameters. This paper examines the perturbation of mobile communications to ascertain probable causes. The various causes of impairment are examined. Different scenarios of mobile communications environment are presented. Test runs of the four mobile operators’ behavior from a rocky and non-rocky environment in Nigeria are presented. Finally, analysis of percentage call failures and observations are given.
