The tutorial will the stage for the rest of the conference sessions by providing regulatory history, case studies, and background information on millimeter wave. Topics will include jurisdictional, legal, technical, and rulemaking decisions that brought us to where we are today and identification of critical remaining issues in these areas.

Currently, millimeter wave frequencies have high-speed data applications, via backhaul. This panel will focus on mobile examples of mmWave applications, technology, and engineering challenges beyond 5G of mobile backhaul implementations. It will explore the current technologies and their corresponding challenges to determine what new approaches are required to expand capabilities within the millimeter wave community.
Moderator: Todd Martin, Shared Spectrum Company
3GPP is the global initiative for mobile broadband standards. In this panel, 3GPP participants discuss the challenges—and benefits—of standardization of mmWave technologies. They will discuss specific features like initial access, radio protocol architecture, channel coding, multicarrier issues, and connecting to legacy technologies. These features are different for each radio technology, adding to the standardization challenge.

A key aspect of fifth generation (5G) cellular communication lies with the millimeter-wave (mmWave) spectrum to meet the growing demand for greater capacity, denser networks, and lower latencies.Many challenges ahead meet the designer of this new 5G mmWave-spectrum cellular communication systems.One fundamental challenge is the quantification of the mmWave radio propagation in urban micro, outdoor-to-indoor building penetration, stadium, data backhaul, over-the-air testing and other emerging scenarios.Further, at mmWave frequencies and for wide modulation bandwidth of the signals, the hardware performance becomes increasingly non-ideal.Sampling circuits operating at the state-of-the-art speeds, may introduce distortion including quantization noise, nonlinearity, and imbalance (if interleaved).Other components such as amplifiers or frequency converters may also distort a transmitter or receiver response.During this session, panel researchers from industry, academia, and government discuss these challenges by exchanging ideas, methodologies, modeling and channel propagation measurements.

Millimeter-waves, with their associated promise of massive bandwidths and potential for network densification, have been heralded as the solution for the exponentially growing hunger for high-speed data and greater system capacity. Despite nearly two decades of research and development, mm-wave end user devices are still prohibitively expensive. Moreover, mm-wave system design and planning have introduced new engineering challenges that are only just beginning to be addressed. This panel will explore the system-level challenges associated with deploying a mm-wave network, as well as techniques that could extend the usefulness of below 5 GHz system. It will also address significant design challenges at mm-wave frequencies.
