Abstract—Various Construction materials cause significant losses when subjected to wireless signals along the path of propagation. A change in the signal strength, losses and user experience occur as a result of the complex composition of the materials. This paper is aimed to find out how 2G (1800MHz) signal is affected when subjected to an enclosure dimension (0.24mx0.20mx0.16m), made of 3 species of timber namely; Chlorophoral excels (Iroko), Afzelia Africans (Apa) and Gosswei Lerodendrin balsamic ferum (Agba); a reflective glass and solid reinforced concrete. This paper study focused on, Received Signal Strength (RSS), Upload and Download speed (Mbps) and Jitter (ms). The steps taken involve finding the penetration loss from the RSS with their respective data representation and drawing fact from the represented data. The result of this work presented that, material C has 46.1%×〖10〗^(-2) increase in indoor signal strength, material E has insignificant change in indoor signal strength, material D, B and A has 1.0%×〖10〗^(-2) decrease, 10.2%×〖10〗^(-2) increase and 16.4%×〖10〗^(-2) increase respectively in indoor received signal strength. The result from QOS parameter– Jitter(ms) are compared for both outdoor and indoor, this relatively showed that material B, C and E will provide improved experience to the user.
