Book Description
Modern day cellular mobile networks use Massive MIMO technology to extend range and service multiple devices within a cell. This has brought tremendous improvements in the high peak data rates that can be handled. Nevertheless, one of the characteristics of this technology is large variations in the quality of service dependent on where the end user is located in any given cell. This becomes increasingly problematic when we are creating a society where wireless access is supposed to be ubiquitous. When payments, navigation, entertainment, and control of autonomous vehicles are all relying on wireless connectivity the primary goal for future mobile networks should not be to increase the peak rates, but the rates that can be guaranteed to the vast majority of the locations in the geographical coverage area. The cellular network architecture was not designed for high-rate data services but for low-rate voice services, thus it is time to look beyond the cellular paradigm and make a clean-slate network design that can reach the performance requirements of the future. This monograph considers the cell-free network architecture that is designed to reach the aforementioned goal of uniformly high data rates everywhere. The authors introduce the concept of a cell-free network before laying out the foundations of what is required to design and build such a network. They cover the foundations of channel estimation, signal processing, pilot assignment, dynamic cooperation cluster formation, power optimization, fronthaul signaling, and spectral efficiency evaluation in uplink and downlink under different degrees of cooperation among the access points and arbitrary linear combining and precoding. This monograph provides the reader with all the fundamental information required to design and build the next generation mobile networks without being hindered by the inherent restrictions of modern cellular-based technology.

Book Description
A guided tour of the physical Internet, as seen on, above, and below the city’s streets What does the Internet look like? It’s the single most essentail aspect of modern life, and yet, for many of us, the Internet looks like an open browser, or the black mirrors of our phones and computers. But in Networks of New York, Ingrid Burrington lifts our eyes from our screens to the streets, showing us that the Internet is everywhere around us, all the time—we just have to know where to look. Using New York as her point of reference and more than fifty color illustrations as her map, Burrington takes us on a tour of the urban network: She decodes spray-painted sidewalk markings, reveals the history behind cryptic manhole covers, shuffles us past subway cameras and giant carrier hotels, and peppers our journey with background stories about the NYPD's surveillance apparatus, twentieth-century telecommunication monopolies, high frequency trading on Wall Street, and the downtown building that houses the offices of both Google and the FBI's Joint Terrorism Task Force. From a rising star in the field of tech jounalism, Networks of New York is a smart, funny, and beautifully designed guide to the endlessly fascinating networks of urban Internet infrastructure. The Internet, Burrington shows us, is hiding in plain sight.
