IEEE 802.15.4 compliant in-building wireless sensor network
Jędrzej Drozdowicz, Gustaw Mazurek · 2015
An increasing number of wireless networks operate in indoor environments nowadays. In this paper the development of a wireless sensor network with the goal of network flexibility, energy efficiency and versatility is presented. The proposed network supports transmission in 868 MHz or 2.4 GHz frequency bands, in accordance with the IEEE 802.15.4 standard. The performance of the network was tested in both outdoor and indoor environments. The quality of indoor transmission in both frequency bands (868 MHz and 2.4 GHz) was experimentally checked and compared to the results from another system operating in the 433 MHz frequency band in the same scenario.
