function path_loss_in_db = pathloss(frequency N_ch distance)
% === Path loss model based on measurement results in a hospital room ===
% frequency: frequency bands ( 1: 400MHz 2: 600MHz 3: 900MHz 4: 2450MHz 5:UWB)
% N_ch: # of path loss realizations
% distance: distance between Tx and Rx in mm

% a and b: parameters in linear fitting
% sigma_s: standard deviation of a Normal distribution
