This paper involves the design and implementation of cell phone detection mobile robot. This is applicable in examination halls, private conferences and meeting rooms in which the using of cell phones is highly restricted. The robot is able to detect the presence of unauthorized communications by active phones and then distort them. The detection process is achieved by implementing an electrical circuit for sensing undesirable signals and using NodeMCU for interfacing the robot with a main computer unit. The main computer unit is used as a controlling platform in terms of mobile robot navigation as well as detection and jamming activating. This is accomplished by creating a graphical control panel programmed using a special HTML script. In this work, the cell phone detection mobile robot has been applied in an examination hall to simulate real educational environment. The robot has detected active calls by cell phones with a circle diameter of 1.2 meter and then jammed them directly. The whole area has been covered for detection and jamming by roaming the robot wirelessly via the remote main computer. Different voltage measurements for different detection distances have been recorded.

Cellular network planning is an essential stage that precedes implementation phase. The planning performance is widely dependent on the terrestrial features of the environment where a network is planned to be implemented in. This work involves the cellular planning of three networks applied in two cities, namely Baghdad and Shaqlawa, with different terrains. Two networks are planned in a flat terrain (Baghdad city) using universal mobile telecommunications system (UMTS) and long term evolution (LTE) technologies and one network is designed in a hilly terrain (Shaqlawa city) utilizing UMTS technology. In this study, several calculation themes are applied to evaluate the performance of the proposed planning such as coverage, power level, carrier to interference ratio, best server and elevation calculations. Also, some clients and points are positioned across networks to measure power levels, interference and coverage at different locations more precisely. The measurements show that the UMTS networks cover an area of 63.62 km2 compared with 81 km2 coverage area in the LTE network with different quality of service graduating from quadrature amplitude modulation (QAM16) and quadrature phase shift keying (QPSK) to voice services. In addition, comparisons between the networks are discussed and enhancement suggestions are presented in this paper.
