Jim Young, Senior Vice President & Chief Operating Officer, Crown Castle

Evolving Wireless infrastructure Architecture in the United States

Abstract: Demand for wireless broadband data continues to increase at rates that challenge wireless carriers ability to develop networks to support that demand. Traditional tower based networks, when combined with additional spectrum assets can help relieve network congestion, but are insufficient to maintain the quality of service customers expect. Network architectures utilizing fiber based small cell components are bridging the capacity gap. Centralized Radio Access Node (CRAN), WiFi, Carrier Aggregation and video compression technologies will all be used to meet data demand needs. Discussion will provide a broad survey of these solutions as well as insight into current deployments in the U.S.

Bio: Jim Young was appointed Chief Operating Officer of Crown Castle in February 2009. Prior to this appointment, he served as President, US Tower Operations from October 2005. He is responsible for the management of all operational groups including the four Areas, Property Management, Operations, Service Delivery, Performance Improvement, Information Technology, and National Site Development. With more than 21 years of experience in the telecom industry, Mr. Young has served in several key capacities for various organizations. Prior to joining Crown Castle, he served as the Northeast Region Vice President of Network Operations for Sprint/Nextel, before that spending several years with GTE in a variety of leadership positions across multiple disciplines.

A New Approach to Providing Quality of Resilience Classes

Abstract: There is an increasing need for supporting services with high resilience requirements over future communications networks. For example, public safety emergency calls, networked medical systems and smart power grid communications. From a service provider’s perspective, there is a need to support classes of quality of resilience (QoR) in a fashion similar to quality of service classes. The basic concept is to categorize traffic into classes and provide different levels of availability and fault protection for each class. The goal of providing QoR classes is to just meet availability requirements without over-engineering the network. In this talk, we introduce a novel method for providing QoR classes that simplifies the network design and achieves both high resilience and differentiation. Our approach, utilizes the spine concept of embedding a sub-network at the physical layer with comparatively high availability link and node values. This lays a foundation for differentiation between multiple classes of flows. Then, cross layer mapping and spine-aware routing are performed in a way that transfers this differentiation capability to the upper layer network and flows. We provide two joint routing-mapping optimization formulations and evaluate their performance in a multilayer scenario showing the advantages of our approach.
