**Abstract**

Field inspection process of the cellular network infrastructures is an important step during Radio Network Optimization. It allows the collection of all physical data of needed relays to efficiently optimize the network performances. The humanbased performed inspection is initiated after the raise of a set of issues. The initiated operation is intended to resolve the cited issues as the errors in physical parameters extraction of relays, human safety issues as burns and falls, etc. This work revolves around an assembly and configuration of quadrotor drones in telecommunication relays inspections because of their easiest construction and their rapidly services. The user of the realized UAV can control and initiate the operation so intuitive thanks to its graphic control interface.
