With the governments strongly support and promotion, IOT (Internet of Things) has become popular in our life nowadays. In order to build China national IOT application technology, in this paper, IOT application architecture based on Beidou navigation system is presented and analyzed in detail. And the IOT network layer, which consists of wireless sensor network, cellular mobile communication network and Beidou navigation system, is mainly expounded. This architecture not only expands coverage area of IOT, but also enhances reliability and economical efficiency of the whole IOT system. Thereby, it can bring more new applications in IOT field.

This study presents the optimization of signal coverage area in third generation WCDMA technology of mobile communication networks, aim at improving signal coverage area or overcoming the presence dead zone in mobile communication network. Various parameters that affect Signal coverage area in mobile communication network were determined. Optimization mathematical model based on Lagrange mathematical method was developed in line with the necessary parameters and characteristics. The developed mathematical model was simulated using MATLAB and Wolfram Mathematical Software using data obtain from mobile communication Network ‘A’ at Asaba, Delta State. The obtained data were number of duplex channels, frequency, load capacity of the base station, interference, distance power received, power transmitted etc. The result obtain are the critical points with fade-off of the radio signal. The coverage area indicates a non-linear function, therefore to minimize threshold parameter such as interference; pathloss and power received values will increase as the coverage area of the base station increases.
