The measurement system consisted of a spectrum analyzer and a log-periodic antenna. Non-line-of-sight (NLOS) propagation (in furnished rooms) was investigated. All the measurement sites mentioned in this paper are located in the Division of Information Technology at Universiti Putra Malaysia. The furnished rooms mentioned above were a teaching laboratory and a computer laboratory. The measured path losses were compared with the results obtained using deterministic models, namely the geometrical optics model and the uniform theory of diffraction model with the aid of image theory. The predicted results showed good agreement with the measured data for the NLOS environment, with an absolute mean error that ranged between 1.61 and 3.07 dB. 2014-03-20T07:03:09Z 2014-03-20T07:03:09Z 2013-08 Article Wireless Personal Communications, vol. 71(3), 2013, pages 2197-2213 0929-6212 http://link.springer.com/article/10.1007%2Fs11277-012-0931-9 http://dspace.unimap.edu.my:80/dspace/handle/123456789/32912 en Springer Science+Business Media New York |
