performing the ray tracing analysis on each of the plurality of split regions based on the condition and the map data;
identifying whether an error between a result of the ray tracing analysis on each of the plurality of split regions and a preset result is within a threshold;
performing communication simulation on the analytical region based on the result of the ray tracing analysis, in case that the error is within the threshold,

wherein the ray tracing analysis is performed using a mmWave frequency band, and
wherein the communication simulation is performed for the network design.

2. The method of claim 1 ,
wherein the condition for the ray tracing analysis is associated with at least one parameter of ray spacing, reflection, diffraction, or transmission in a ray tracing (RT), and
wherein a computation speed of the ray tracing analysis is improved based on the at least one parameter.

3. The method of claim 1 , wherein splitting the analytical region is performed further based on information on at least one of a transmission speed, a transmission capacity, a transmission distance, a bandwidth, a modulation and coding scheme (MCS), a number of antennas, an antenna gain, a number of RF chains, transmission power for each RF chain, effective isotropic radiated power (EIRP), a noise figure (NF) or sensitivity which is an index indicative of performance of a transmitter or receiver.

4. The method of claim 1 , further comprising determining a transmission candidate location and a reception candidate location within the analytical region using the map data,
wherein the transmission candidate location is determined based on information on at least one of a beam width of a transmitter, an installation height of the transmitter, whether a transmitter is to be down tilted, a range of the down tilting of the transmitter, a road width, or a deployment of buildings.

5. The method of claim 1 , further comprising determining a transmission candidate location and a reception candidate location within the analytical region using the map data,
wherein the reception candidate location is determined based on at least one of information indicative of a local characteristic of the analytical region or information indicative of a deployment scenario of the analytical region.

6. The method of claim 1 , further comprising transmitting the result of the ray tracing analysis to a base station positioned in the analytical region, the base station communicating with a terminal based on the result of the ray tracing analysis.
