Current Research: Modeling Mobile Wireless Communication

Since the end of 2010, more mobile devices have been sold each year than stationary personal computers.  The general public is addicted to instant access using mobile communication for business coordination and personal communication. More importantly, First Responders continuously move at an incident site requiring them to communicate via mobile wireless networks. Furthermore, all mobile device users inside a building often have problems in communicating to devices outside that building due to weakened radio signals caused by building materials. In some instances loss of wireless network (WLAN or Cellphone) connectivity is merely an inconvenience.  In other instances, it may cause loss of life.

 

The Federal Communications Commission continues to reallocate frequencies to mobile device use. Consequently, our communication may be more impacted by the effects of modern building materials. We can reduce the impact by improved models of the effects of building materials on our mobile connection inside buildings. My modeling is based on empirical field findings as well as measurements of the attenuation of building materials on radio waves at different frequencies to provide enhanced, experimental modeling results.

 

The current research has three major parts.  Part I implements in software, a propagation model from the United States National Institute of Standards and Technology (NIST) to simulate radio wave propagation path loss during a scenario of mobile communication with WLANs. NIST data from 2009 and 2010 and data collected by Dr. Boggs in 2012, and 2013 were the basis for modifying the original NIST experimental propagation model.  Additional data were collected in May 2017. Version X1.0 of this experimental software is available as of September 2018. Part II is an ongoing effort to collect transmission coefficients at specific frequencies for modern building materials. Part III is an effort to provide education in this sub-area of wireless communications through writing, presenting and publishing technical papers. The first white paper can be downloaded Here
