r central SON CHAPTER 2 SELF-ORGANIZING NETWORKS IN LTE DEPLOYMENT Benefit of Cell Outage Compensation There are three advantages to cell outage compensation procedures: Minimizes the damage and downtime until the faulty cell is repaired. Repair activity can be postponed or planned, as the impact will not be that high due to cell outage compensation. This will result in reduced maintenance costs (e.g., no permanent on-call service, smaller stocks of spare parts, combining of trips). Cell outage compensation is extremely useful and critical in places where the frequency of faults is higher. Summary This chapter provided a brief introduction to SON and its benefits and provided an overview of SON and its architecture, deployment aspects, and some of its major features. The following chapter talks in length about the deployment, business, and economic challenges that the fourth generation of mobile telecommunications technology is surrounded by. CHAPTER 3 Deployment Challenges in Evolving 4G Experienced network operators will often agree that every deployment of any technology is a unique experience. Veteran players in the telecom field often have stories to swap when it comes to relating their experiences with the deployment of solutions in the field. For development organizations, design wins might indicate revenues to be enjoyed, but successful deployments are the real crowns to be worn with pride and bragged about in competitive environments. So what it is about deployments that make them such celebrated events upon completion yet such daunting tasks to undertake? There are a variety of reasons for this. Many times, there tend to be problems inherent in the technology itself. The practical aspects of running a business in a highly competitive regulated environment like telecom lead to many other challenges. A critical part of network and service planning rests upon user profiles (i.e., how the users and their usage patterns are projected). The changing nature of real-world users and their usage patterns pose a c
