摘要: Road coverage will be a key issue for the success of connected car applications. In this work, comprehensive analysis radio signal strength fluctuations on roads in Long Term Evolution (LTE) system is presented. For purpose, measurement campaign based drive tests was carried out to assess levels that can expected ordinary by normal in-car terminals country European Union. Measurements were collected 1,000 km road 2 vehicles covering same route. By comparing level samples at geographical location, taken slightly different times, statistical model derived. Then, impact factors (e.g., shadowing, environment, handover, etc.) received from serving cell assessed. Results show large deviations (up 23 dB) are observed location.
