Spectrum Considerations For 5G Key Spectrum Considerations for 5G: Introduction 5G is the future of wireless and it will deliver significant benefits to consumers and many sectors of the economy through the deployment of ultra-fast, highly reliable, scalable, and very low latency networks.1 Spectrum is the essential ingredient in 5G networks and ensuring sufficient access to enough and the right kinds of spectrum is a national priority.2 This paper identifies key technical considerations for policymakers as they proceed with on delivering spectrum bands already identified for next-generation wireless use, and in identifying and allocating additional bands in the near term. For the U.S. to unlock the enormous promise of 5G, policymakers should focus on these key spectrum characteristics in unleashing significant new allocations of low-, mid-, and high-band spectrum: Benefits of 5G Include: 100x faster • Licensed, exclusive-use spectrum • Flexible-use rights • Prioritization of cleared spectrum • Wide channels of contiguous spectrum to enable very high speeds, efficient performance, and multiple antenna technology, and • Use of globally harmonized bands, which enables global scale and roaming. This paper explores each of these considerations in more detail to explain 5G technology, spectrum characteristics, technology enablers, and ecosystem considerations needed to unlock the benefits of 5G. With a continued focus on carefully crafted spectrum policy, the U.S. can expand upon initial 5G launches and announcements and provide robust 5G networks that American businesses and consumers can utilize for connectivity, productivity, and innovation. 100x more connections 5x more responsiveness 2 What is 5G? Tomorrow’s 5G networks will surpass the capabilities of today’s networks. These networks will offer unparalleled speeds (up to 100x faster than 4G LTE) and enable real-time connections with improved responsiveness (more than 5x more responsive), thereby supporting entirely new services, applications, and a massive increase of Internet of Things (IoT) devices (more than 100x the current number of devices).3 Up to 100x Faster Each successive generation of wireless technology leapfrogs the capabilities of the prior generation, often in dramatic ways. We witnessed these leaps between 2G and 3G, between 3G and 4G, and we will see them realized in the next leap to 5G. The most tangible change between generations of technology is a significant increase in network speed.4 5G will be no exception.5 While 4G LTE networks are fast, 5G networks will be much faster. With wide channels of mid- and high-band spectrum along with innovations like massive multiple-input and multiple-output (massive MIMO) antennas, 5G technology, with its new modulation, will enable consumers to reach speeds up to 100 times faster than 4G networks, at potentially 10-20 Gigabit/second (Gbps) peak speeds.6 This data throughput enhancement will enable more rapid downloads (files that would take several minutes to download will take mere seconds), faster access to ultra-high definition video content (including 4K and 8K video), and more immersive experiences in every industry, including healthcare, energy, transportation, law enforcement, e-commerce, logistics, and education, among others.7 5x More Responsive Today, 4G LTE latency rates—the technical term for the delay between your request for data and when your mobile device receives it—are low, roughly 10 milliseconds over-the-air; 50 milliseconds end-to-end.8 5G latency rates will be five to ten times lower—or as low as a few milliseconds over-the-air.9 This reduction 3 in latency will enable near real-time consumer wireless experiences not possible today, unlocking or enhancing services and applications such as vehicle safety and collision avoidance, augmented and virtual reality, and real-time medical applications such as remote medical appointments.10 For example, autonomous vehicles will be one of the transformative societal changes enabled by 5G networks.11 The National Highway Traffic Safety Administration reported the following statistics for the U.S. in 2016: • • • • 7,277,000 police-reported traffic crashes 37,461 traffic fatalities 3,144,000 people injured The economic cost of all traffic crashes for the last reporting year of 2010 was $242 billion.12 A responsive, reliable, and high-capacity 5G system, will transform every aspect of the transportation experience, including allowing v
