To do this, the city will roll out smart solutions to everyday problems that affect the well-being of its citizens with a view toward revitalizing its economy, reducing its resource consumption and better maintaining its infrastructure. One such solution Hong Kong is looking into is whether drones or sensors can monitor its aging infrastructure continuously and signal when maintenance needs to be done. Yet another involves using remote sensors to monitor air pollution and waste bins for a cleaner, greener city. Cities have long dealt with the problems of preserving key resources, maintaining infrastructure and promoting the safety of their citizens. Smart devices automate and streamline the process of solving these problems, offering infinite opportunities to lower operational costs and stay competitive. 5G AND FIBER A mere five years from now, nearly 30 billion sensors will be deployed across the globe with the goal of automating and managing essential city functions, according to the International Data Corporation. To support this astronomical growth in bandwidth needs, smart cities of the future will depend on the deployment of 5G mobile connectivity and strong fiber backbones. 5G is the long-awaited, next- generation model of mobile networks, promising blistering speeds, near-zero latency and as much as 1,000 times the bandwidth of current mobile connectivity. It will make possible a future of smarter, safer cities. At least in cities, 5G will use high- frequency waves in the millimeter spectrum. Millimeter-spectrum waves are capable of carrying much more information than the spectrum used for 4G wireless, but they do not travel as far. To overcome this hurdle, telecom companies will transition from large cell towers to small cell sites – which may be deployed at streetlights – each covering a range of about 250 meters. ough 5G small cells will drastically increase the speeds and quality of experience of mobile connectivity, they will be responsible for carrying data only those last 250 meters – data will make most of its journey along the wireline network. In fact, 90 percent of all internet traffic will still travel along the wireline network, even in a 5G mobile network. To realize the theoretical speeds of 5G mobile networks, cities must continue to invest in deploying strong fiber backbones. Although copper can be used – and worked well for 2G and 3G speeds – legacy copper-based mobile backhauls are already stressed at 4G speeds and are simply insufficient for 5G. Fiber beats copper in almost every attribute important to networking: speed, reliability, security and scalability. Fiber can carry 10-gigabit signals more than 12 miles before speed drops off, and copper can carry 1 Gbps signals only 300 feet. Fiber is also much more secure and has nearly 6,000 times the bandwidth capabilities of copper. e speeds fiber backbones provide are limited only by the equipment transceiving data, meaning fiber infrastructure has virtually limitless scalability as technology continues to improve. at's why cities across the world continue to invest capital in fiber. More than $144 billion will be spent through 2019 on fiber-related expenses, according to a report from the International Telecommunication Union. Cities such as London, Barcelona and even Louisville have already begun experimenting with the potential of IoT devices to improve the efficiency of internal processes and enhance the quality of life for their citizens, using fiber to ensure the strongest, most reliable connections. ose that lay a strong fiber foundation today will be the cities that reap the greatest benefits from the transition to 5G and a smarter, safer future. v Diane Bloemker is a sales representative for Arch Fiber Networks, a fiber optic development company.
