Recently, there has been considerable interest in new tiered network cellular architectures,
which would likely use many more cell sites than found today. Two major challenges will be i…

The proliferation of internet-connected mobile devices will continue to drive growth in data
traffic in an exponential fashion, forcing network operators to dramatically increase the …

This paper compares three candidate large-scale propagation path loss models for use
over the entire microwave and millimeter-wave (mmWave) radio spectrum: the alpha-beta-…

Wireless data traffic is projected to skyrocket 10 000 fold within the next 20 years. To tackle
this incredible increase in wireless data traffic, a first approach is to further improve spectrally …

This paper presents and compares two candidate large-scale propagation path loss models,
the alpha-beta-gamma (ABG) model and the close-in (CI) free space reference distance …

Multi-antenna technologies such as beamforming and Multiple-Input, Multiple-Output (MIMO)
are anticipated to play a key role in “5G” systems, which are expected to be deployed in the …

This paper presents key parameters including the line-of-sight (LOS) probability, large-scale
path loss, and shadow fading models for the design of future fifth generation (5G) wireless …

There is growing interest in using millimeter wave (mmWave) frequencies for future access
communications based on the enormous amount of available spectrum. To characterize the …

To meet the explosive growth in traffic during the next twenty years, 5G systems using local
area networks need to be developed. These systems will comprise of small cells and will use …

In the past decade, large scale mobile phone data have become available for the study of
human movement patterns. These data hold an immense promise for understanding human …
