Resumo(s)
This paper presents an enhanced methodology in order to introduce redundancy requirements in the Low-Power Wide-Area (LPWA) networks radio planning for Internet-of-Things (IoT). The Jake's Curves were extended, allowing to compute new log-normal fading margins which traduce combined coverage and redundancy requirements. The methodology was applied developing a LPWA SIGFOX network simulator for a typical urban environment. The double and triple redundancy requirement produced a 10 dB increase in the log-normal fading margin, reducing the cell range to one half, which roughly quadruples the site density. In fact, assuring redundancy enhances the networks's quality of experience, but strongly increases the network investment in base-station equipment and site acquisition. This new approach allowed to compute new site grids and to introduce the concept of assisted planning for IoT networks, where the most suitable candidates among a site list will be automatically chosen, avoiding the inefficient and ineffective trial and error method in radio planning.
