The Defense Network of Tomorrow—Today

Enterprise and residential market dynamics, 5G, and the cloud are driving new applications—and creating new revenue opportunities for Communications Service Providers (CSPs). But these emerging use cases are also creating challenges: new traffic patterns, the move to virtualized and distributed applications, and the need for higher bandwidth and lower latency connectivity to end-users. IP/Optical convergence can play a key role in helping CSPs address these, but where does the path to architecture evolution begin? For every CSP, the journey is unique. With Ciena’s solutions, CSPs can start—and build—from their existing networks to evolve to a more streamlined, programmatic infrastructure that can serve as the foundation for innovation in the distributed services and content era.

Traditional LAN infrastructure deployed throughout enterprise and other markets has been highly effective at incorporating the growing domain of Ethernet devices into a unified infrastructure. These systems work best when end users need higher bandwidth and more flexibility across their systems, when user density is high, and when interoperability for future changes is paramount.

By now, everyone has heard the terms desktop virtualization and VDI It seems like we’ve been pounded with marketing propaganda about these technologies from companies like VMware, Citrix® and Microsoft® since 2006. But if desktop virtualization is so good, why are most of the world’s desktops still “old-style” physical desktops and laptops?

Operators are picking up serious momentum when it comes to 5G roll outs. As of December 2021, 487 operators in 145 countries or territories had invested in 5G mobile or fixed wireless networks with 200 of these having launched some level of 5G network coverage. However, there is still a long road ahead when it comes to ensuring that 5G meets its potential and drives maximum ROI. A big stumbling block to overcome will be to ensure comprehensive coverage, in particular, in buildings.

Alongside connectivity and power, a third area – the antenna – needs to be equal attention because of the fundamental impact it has on device performance. The antenna is the means by which an IoT device receives and sends signals to the outside world and therefore is a fundamental element of an IoT device. However, antenna decisions are often neglected until the end of the development process, resulting in unnecessary compromises and sub-optimal siting of antennas that could have been avoided with better planning and design.

Nippon Telegraph and Telephone Public Corporation (NTT) launched the world’s first mobile communication service using a cellular system on December 3, 1979. Since then, the radio access technology for mobile communications has evolved into a new generation system every 10 years. Along with technological development, services have also made progress. In the years from the first generation (1G) to the second generation (2G), the services were mainly voice calls, but finally advanced to simple text messaging.
