Propagation path loss model for different wall material for LTE indoor environment

This project is to study and investigate propagation path loss model for different wall material to introduce in LTE indoor environment. The project used four frequencies of Long Term Evolution (LTE) frequency bands such 850 MHz, 1800 MHz, 2300 MHz and 2600 MHz proposed for femtocell application in Malaysia. This project focused on indoor environment because most of the time user spent their daily life in indoor area more than outdoor. Moreover the indoor environment it had greater propagation path loss then outdoor because effected by number material wall and type material wall. Thus main indoor femto channel model formula for this project used 3GPP TR36.841 that frequency carrier was 2000 MHz. Main purpose of this project is to investigate the effect of different walls material such brick, concrete, glass and plasterboard with the number wall material which 1, 2, 3 and no number of wall layers toward the propagation path loss with different distance user equipment (LIE) from Home eNobe B (HeNB) in 2 section. Section 1 the HeNB placed on corridor while section 2 HeNB placed in the house area study room. The different wall’s thickness of wall such brick is 0.1778m, concrete is 0.2032m, glass is 0.0127m and plasterboard is 0.0762m that usually used in building structure also gave significant effected to the wireless signal when it passed through the building. Additional, the college Delima UiTMPP at 2nd floor used to represent the design building structure for this study to compare with model 3GPP TR 36.814 indoor femto channel. Then from four frequency chosen for this project, the lowest frequency band was 850 MHz and 2600MHz for the higher frequency band to optimize the performance indoor femto channel model. Moreover the glass was the best material for this propagation path loss model because produce lowest path loss in indoor environment at collage Delima UiTMPP 2nd floor.
