Performance of mmWave Channel Model on 28 GHz Frequency Based on Temperature Effect in Wonosobo City

5G technology is predicted to use high frequency, where high frequency presents a new challenge, namely the problem of wave propagation attenuation which is influenced by natural conditions such as temperature, barometric, rainfall, and humidity. The difference in the shape of the earth's contours and natural conditions in each region requires research to find the most appropriate channel model for use in that area. The channel model is obtained based on a representative value from the simulation results of the Power Delay Profile (PDP) using the New York University Simulation (NYUSIM) channel simulator. Evaluation of work in research using a frequency of 28 GHz, QPSK modulation, 200 MHz bandwidth and CPOFDM as multiple access. The results showed that the comparison of the 5G channel model obtained the blackout probability of lE-04 at a maximum temperature of 30.4 degrees celsius and a minimum temperature of 18.0 degrees celsius so that the Eb/N0 required for half coding rate was 15.352 dB and 15.122 dB, three-quarter coding rate was 16.625 dB and 16.329 dB and the coding rate one is 17.711 dB and 17.487 dB. Judging from these results, it can be seen that temperature affects the performance of the 5G communication system in Wonosobo City.
