Summary: As wireless communications have become ever more important, access to wireless spectrum has become increasingly difficult. The so-called “spectrum crunch” describes a situation in which there is not enough spectrum available to support all of the networks and devices desired. As a result, a critical capability of wireless devices is the ability to share the spectrum they use with other devices, be they communications devices or not. For example, one class of critical spectrum user is the radar system for weather forecasting, navigation, and defense.
This ability to share spectrum with other users has both regulatory and non-regulatory aspects. From a regulatory perspective, there are rules designating how a wireless system needs to behave in order to protect critical operations, or fairly share the spectrum with other users. Beyond regulation, however, there is freedom of operation, and some devices will make better choices in the presence of wireless interference than will others. Network operators need a way to test the performance of devices in the presence of interference, both to understand their ability to support regulatory requirements, and to understand what kinds of choices they are designed to make.
We will provide an overview of the spectrum sharing landscape, including DFS/radar requirements, new regulatory regimes such as CBRS in the US, and industry-driven activities such as the cellular/Wi-Fi co-existence test plan for LTE-U. In addition, we will discuss how devices that operate under these various conditions can be tested to understand their performance.
Bio: Leigh M. Chinitz is CTO of OctoScope. Prior to joining octoScope, Leigh was the CTO at Casa Systems with a focus on wireless strategy for both Wi-Fi and small cell technologies. He joined Casa from Cisco where he was a Solutions Architect in in the Service Provider Wi-Fi Advanced Services team with a focus on the solution architectures for service providers looking to deploy Wi-Fi networks. Before that he was a solutions architect for a UMTS femtocell company, a solutions architect for a CDMA femtocell company, CTO for a Wi-Fi company, and a systems technology researcher for Motorola, where his work in areas including CDMA networks, push-to-talk, wireless system simulations and digital TV resulted in several patent awards. He was later was responsible for coordinating Motorola’s participation in FCC proceedings. He has worked in wireless and data communications since 1993, addressing areas such as macrocellular network design and simulation, femtocell network architecture, and Wi-Fi solution design. His areas of focus include wireless network simulation and design, overall solutions architecture, business development, and policy and regulation.
He is the holder of 20 US patents, an experienced speaker at industry conferences, and a participant in IEEE, TIA, and ITU standards activities.
