Wideband mobile propagation measurements at 3.7 GHz in an urban environment

WiMAX urban coverage based on the Lee model and the Deygout diffraction method

“…For the case of WiMAX links, the practical frequency band considered is 3.5 GHz, which dictates other standard conditions. To the best of the knowledge, there are three reports in the open literature concerning to path loss measurements in urban areas at the 3.5 GHz band [13][14][15]. From these, the results obtained by Walden and Rowsell on highly built-up urban areas of United Kingdom [13] are taken into account here as a base for the standard conditions used in the Lee model.…”

“…From these, the results obtained by Walden and Rowsell on highly built-up urban areas of United Kingdom [13] are taken into account here as a base for the standard conditions used in the Lee model. This paper is considered provided that, in average, the scenarios where the measurements were carried out, could be some similar to the case of the down town of Mexico City; in addition, all the parameters needed to make up the standard conditions are available in [13] (whereas the work of Porter et al [14], for instance, present only a partial set of values at all). Then, the parameters used by Walden and Rowsell for the 3.5 GHz measurements campaign reported in [13], and used here as standard conditions was mounted at m 28 over the ground.…”

Experimental BER Performance Evolution of Equalizations and Matched Filter Bounds for Single-Carrier WiMax Radio in 3.5 GHz

“…The studies have measured excess delay spread of the channel in 3.5 GHz region for indoor and outdoor applications [9,10,11]. One of the earlier work on evaluating BER performance by experimental channel measurements was done by Takai for multipath resistive modulation methods and his work involves with measuring excess delay spread, obtaining BER performances experimentally and comparisons by the simulation results [12].…”

Peer-to-peer urban channel characterization for military UHF band

“…Seidel [49] performed his measurement in suburban area of Stuttgart at 900MHz and obtained the path loss exponent of 2.8 with shadowing variation of 9.6dB. Porter [50] also reported n value of 3.2 and value of 9.5 dB in urban channel at frequency of 3.7GHz. Range of 7dB-11dB for shadowing standard deviation has been reported in many research works.…”
