It is used to predict the propagation loss for a wide range of environments, whereas, the Friis free space model is restricted to unobstructed clear path between the transmitter and the receiver. CDMA Channel Model. For example, the channel model cannot support various modeling requirements for new applications of 5G [4]. In the O2I scenario, the outdoor macro-cell BS is mounted above rooftop levels of surrounding buildings. A propagation loss model can be "chained" to another one, making a list. For example and if we consider the UMa model for Line Of Sight (LOS) case, the path loss formula is given as following : Path loss =28.0+22*log10⁡ (d)+20 log10⁡ ( fc) ………………… (2) One important example is the recently developed 3D-urban micro (UMi) and 3D-urban macro (UMa) channel models for LTE [1]. simulation tests that are based on a 3D multi-ellipsoidal propagation model (MPM) [29-31]. For the UMa, UMi and Indoor-O￿ce scenarios we support both the default and the optional NLOS propagation mod-els, and the latter is selected by setting the OptionalNlos attribute to true. • Aggregation of the traffic flows bitrates: to estimate the total link or node capacity. Examples demonstrate addition of propagation channel effects to model 3GPP pedestrian (EPA), vehicular (EVA), urban (ETU), high-speed train (HST), MIMO fading, and moving propagation scenarios. For each of these conditions, it defines different parameters for mean propagation path loss, macroscopic fading, and microscopic fading.
