Deploying, maintaining and upgrading to LTE specifications are top enter- prise priorities, bringing with them a number of challenges to keep LTE networks operating effectively and efficiently. With data speed hundreds of times greater than its 3G predecessor and extended capacity and battery life, today's LTE devices are putting greater power at the fingertips of wireless cus- tomers. We all know that once that bar is raised, you must be able to consistently meet those ris- ing customer expectations. Success in today's communications landscape means continually focusing on the highest quality experience for wireless users. Optimizing LTE Performance While 2G and 3G networks were primarily voice systems, LTE is primarily a data system that can deliver the full multimedia experience to users, which means new considerations when it comes to selecting, installing and maintain- ing equipment. Ensuring clear communication signals to increasing numbers of users over ex- panding geographic areas is key to maintaining user satisfaction. The challenge is even more complex in an environment in which equipment is constantly evolving to take advantage of new and existing locations. For LTE to deliver its full potential, deployment and maintenance require precise engineering and experienced insight to overcome some of the unique challenges posed by LTE, including the following: Because optimal LTE performance requires a higher signal-to-noise-ratio (SNR) than any technology, noise can present a major obstacle to a smoothly operating LTE network. Caused largely by disruptive signals within a radio channel, noise is typically more difficult to isolate and mediate than interference. LTE performance is significantly impacted by any kind of interference, so the network's signal-to-noise-plus-interference ratio must be higher than any previous technology. Interference is more prevalent in urban and suburban areas and can be caused by a number of factors, including nearby electrical equipment or poorly installed or Prepare Now For IP Network Transitions Submitted by UTC For many years we have heard about the cord cutters who have disconnected their traditional phone service to rely exclusively on their mobile phones. At the majority of businesses, Voice over Internet Protocol (VoIP) phone systems based on IP Centrex and hosted IP PBX services have displaced the once dominant analog Centrex and PBX systems providing Plain Old Telephone Service (POTS). This situation has created such pressure on the incumbent Local Exchange Carriers (LECs or carriers) that they have recently petitioned the Federal Communications Commission (FCC) to allow them to discontinue the traditional time-division multiplex (TDM) network that is based on the two-wire copper loop. Subsequently, the FCC has issued a Notice of Proposed Rulemaking, which "focuses on the technological revolution involving the transition from networks based on time- division multiplexed (TDM) circuit-switched voice services running on copper loops to all-Internet Protocol (IP) multimedia networks using copper, co-axial cable, wireless and fiber as physical infrastructure". Big deal, you say, and how does this affect my utility's telecommunications business? In a most profound way, this is a truly trans- formative event in utility telecommunications. This is an event that is neither optional nor voluntary for utilities. Unfortunately, many utilities are not aware of the impending dis- continuation of the lines at the core of their telecommunications operations. So much so, that utilities can be caught off guard and can be lucky to negotiate a grandfather arrangement with a LEC after it has already received approval from the FCC to discontin- ue the services critical for the utility. The Utilities Telecom Council (UTC) is an international trade group for the information, operations and communications technology professionals in the utility industry. As part of the UTC, the Smart Networks Council (SNC) has created a white paper on the IP Success in today's communications landscape means continually focusing on the highest quality experience for wireless users.
