There are two basic ways to deploy wireless LAN access points in an indoor scenario:
manual deployment using a site survey based on empirical measurements or planning …

This paper contains measured data for 2.5 and 60 GHz in-building partition loss. Path loss
measurements were recorded using a broadband sliding correlator channel sounder which …

The sliding correlator technique remains one of the most versatile and effective methods for
sounding the radio propagation channel in next-generation wireless systems. Despite their …

The propagation of ultra wideband (UWB) signals in indoor environments is an important
issue with significant impacts on the future direction and scope of the UWB technology and …

The wide harmonized spectrum in the unlicensed 60 GHz band has been considered for
WPAN standardizations. Recently there is also growing interest in the industry to use the …

The wireless spectrum below 6 GHz in the United States, and throughout the world, has
become congested as a result of the widespread use of smartphones and tablets. Wireless …

Despite the rapid development of wireless technology, there has been little application of the
technology to improve railroad crossing safety. We present vehicle-to-railroad channel …
