I think 5G technology needs to introduced. but its still under in development state: Top 5 challenges in the telecommunication industry in 2019 Telcos have to decentralize the purchasing and decision power, both internally and externally, because of the essential agile reconfiguration of the cloud. With the availability of new technologies, the variety and quality of services from telecom companies and internet service providers (ISP) are increasing, profit margins are decreasing, and the lines between telecom companies and technology vendors are blurring. Hence, telcos have to take a fresh look at the level of ICT innovation and adapt their organization to digital transformation by creating strong cross-functional interfaces and by seeking tools for maintaining organizational flexibility. With millions of subscribers, a variety of new products, bundled and customized solutions, the operational support services like service configuration, order fulfillment, customer care, and billing are becoming increasingly complex. Hence, the cost of handling these operations require resources and different tools, thus, increasing the financial overhead. Telecommunication providers need to upgrade their IT and connectivity infrastructure and focus on providing data and voice services that are high quality, reliable, and affordable. Security of the networks has become a major priority for the telcos and they are facing challenges with the emergence of new threats that are powered by new technologies. So, a number of operational and technical innovations are needed to meet customer expectations of complete system security from network till the device level. 5. One more challenge waiting in the wings for telcos and ISPs is the impact of Internet of Things (IoT) that is leading to explosive growth in the connected devices. This growth is generating billions and trillions of new data sources and thus, it is expected that this growth will push the data to be handled by networks to zettabytes per year
