WLS-5000 Applied Electromagnetics Wireless Telecommunications Lab-10 Indoor / Outdoor Path Loss Calculator 1 Lab Report Prepared By Name: ________________________ Name: ________________________ Student ID: ____________________ Student ID: ____________________ 2 Objectives Learning how empirical path loss models are developed. Implementing a path loss predicting calculator for indoor and outdoor transmission environments. 3 Materials Computer with MS Excel (will be provided in the lab) 4 Information Propagation has many components such as refraction, diffraction, reflection, scattering and multi-path fading. Due to the complexity involved with modelling the propagation environments, empirical path loss predicting models have been developed based on field data and measurements. The path loss models are generally mathematical functions that take inputs or variables describing the environment parameters and calculate the estimated total path loss based on these variables as an output. With the advancement in mobile technologies and the growing need for reliable connectivity and wireless network capacity, indoor base stations are increasingly becoming an important service offering by network providers. In this lab, we will use the International Telecommunication Union’s (ITU) radio propagation model that estimates the path loss inside a residential or commercial space (i.e. a room, a space divided by walls or floors). Using ITU’s model and MS Excel, we will build an Indoor Path Loss Calculator. We will also practice and build a path loss calculator based on the Hata- Okumura model. 5 Pre-lab Assignment Review the class notes on RF Signal Propagation. Review the ITU’s indoor path loss model in the following link: https://www.itu.int/dms_pubrec/itu-r/rec/p/R-REC-P.1238-0-199705-S!!PDF-E.pdf 6 Experiment Procedure Humber College Institute of Technology and Advanced Learning
WLS-5000 Applied Electromagnetics Wireless Telecommunications 6.1 Part-A: Indoor Path Loss Calculator 1. Review the ITU’s indoor path loss model in the following link: https://www.itu.int/dms_pubrec/itu-r/rec/p/R-REC-P.1238-0-199705-S!!PDF-E.pdf 2. Using the provided formulas and tables, create a path loss calculator in MS Excel as shown in Figure 1. Please build your calculator to take the inputs/variables and calculate the total indoor path loss based on the inputs. Note : Please assume for this lab, we will ignore the shadow and fading effects. Figure 1: Indoor path loss calculator example. 3. Using your calculator, find the values for the following scenarios: (a) (b) (c) (d) 4. Please attach your calculator file or screen shots with your submission. 6.2 Part-B: Outdoor Path Loss Calculator (Using Okumura-Hata Model) 1.
