Responsibilities: Data collection and simulation. Provide the Radio Network design data and simulation result as the customer requires, such as the antenna high, tilt, azimuth, coverage result etc. Perform link budget, design criteria and traffic analysis Good understanding of antenna theory (aperture, gain, beam width, dipole vs.
isotropic), antenna performance (return loss, impedance matching, etc.), and engineering tools (spectrum analyzer, site master, etc.). Make the evaluation of the Mobile Network and provide the expansion plan Monitoring and optimize the Network KPIs to assure it reach the target value. Such as the Drop call rate, Call setup success rate etc.
Analyse the Drive test result and find the Network Problems with the Post process tools Analyse the system features and parameters to optimize the network performance KPIs Provide Optimization solutions and suggestion to improve the network quality Qualification: Proficient knowledge of mobile communication and principles of GSM/CDMA/WCDMA/LTE products, signaling flow and protocols, electromagnetic theory, radio transmission, antenna system etc. Comprehensive understanding of Radio frequency channel environment (fast fading, slow fading, time dispersion, scattering, diffraction, wavelength/frequency dependence, etc.) and proper prediction model selection (Okomura, Hata, COST231, etc.) and their key parameters calibration for various frequencies Good knowledge at Mobile system topology and system parameters of at least one of the main technologies (GSM/GPRS, EDGE, WCDMA,LTE etc.). Related planning and optimization work experience on 2G, 3G, 4G is preferred Fluent in English is mandatory, ability to speak Danish is preferred
