Nokia today announced that DISH has selected Nokia’s NetGuard solution to assist with securing the United States’ first cloud-native, Open RAN-based 5G wireless network. This partnership will enable DISH to safeguard 5G network slices, which will be provisioned to support enterprise and wholesale customers.
Each 5G network slice can extend from the device through the radio, access, transport and core networks to each application server, and every path can be isolated and secured. Nokia’s NetGuard Security suite will be deployed within a cloud-native environment to provide security services through slice-specific Service Level Agreements (SLAs).
DISH is deploying NetGuard to support the security orchestration, automation and response capabilities needed to rapidly scale its network and intelligently assess and resolve cyber incidents with minimal manual intervention.
DISH will support new business models with network slicing for both enterprise and wholesale customers. Nokia’s NetGuard security operations enable DISH to efficiently and accurately respond to evolving security threats using automated tools, extended analytics, integrated collaboration processes and an optimized user experience.
Chief Network Officer, DISH, Marc Rouanne said: “Secure network slicing is a key differentiator of DISH’s 5G network, and as we deliver these capabilities to our customers, we will provide a new level of security for their services. Nokia delivers a suite of security tools needed to help our customers unleash the power of network slicing, giving them the security, speed and control they require for their businesses.”
Cloud and Network Services President at Nokia, Raghav Sahgal said: “Nokia is pleased to have been selected by DISH to secure its products and services. We recognize DISH’s need to support its network assets and customers in a fully secure way. Nokia´s NetGuard security operations solutions are built for the new 5G architecture and to meet the performance demands of DISH’s cloud-native network.”
Deutsche Telekom, Cosmote and Ericsson look beyond 100GHz to boost 5G backhaul capacity
As 5G deployments scale up, so does the need for capacity. Communications service providers need additional spectrum to expand the reach of their 5G services. Ericsson has partnered with Deutsche Telekom and Cosmote to trial and test an answer to the challenge – using W-band as 5G backhaul spectrum.
In trials at Deutsche Telekom’s Mobile Backhaul Service Center in Cosmote headquarters, Athens, the partners successfully proved the viability of frequency bands beyond 100GHz, such as W-band, for multi-gigabit wireless backhaul capacities for 5G and 6G.
5G’s increasing capacity demands also apply to transport. Just as radio access networks are starting to use higher frequencies such as 26GHz and 28GHz to allow more capacity, wireless backhaul is also looking into the possibility of higher frequencies with broader channels to enable greater capacities. Wireless backhaul currently uses frequency bands from 4GHz to 80GHz to support 5G transport requirements.
The joint field trial demonstrated for the first time a W-band wireless hop over a 1.5km range with telecom grade availability using pre-commercial equipment. This W-band hop was installed parallel with a 1.5km E-band hop, to show that the W-band has a similar long-term performance to E-band. The trial recorded speeds of 5.7Gbps over the 1.5km distance and topped10Gbps over 1km hops.
The result proved that W-band (92GHz -114GHz) can perform on the same level as the E-band (70/80GHz), which is currently the only frequency band supporting 10Gbps wireless backhaul capacities for 4G and 5G. The W-band is expected to add more untapped spectrum needed for high-capacity wireless transport.
Vice President 5G Solutions, Access & Home Networks, Deutsche Telekom, Dr. Konstantinos Chalkiotis says: “The evolution towards future-proof, cost-efficient and high-capacity wireless backhaul networks will play an important role to accommodate growing traffic demand, increased site location (including small and pico cells) and extend 5G services in the future. The results of our innovation trial with Ericsson confirm the feasibility of using higher frequency bands with wider channels as another solution in our portfolio to deliver high capacity and high performance backhaul for our customers in the 5G era. We hope soon to see those solutions brought into real production in a cost-efficient manner.”
Ericsson, Deutsche Telekom and Cosmote have a long history of joint innovation spanning 3G, 4G, 5G mobile and wireless backhaul networks. Ericsson has been researching technology for high-capacity radios above the 70/80GHz band for more than a decade.
Research Manager, Microwave Systems, Ericsson, Jonas Hansryd says: “Ericsson has a proud history of innovation with Deutsche Telekom. Two years ago, we showed for the first time the possibility to transport more than 100Gbps over a kilometer distance using millimeter wave bands. In our latest joint project, we continue on that path showing the ability to evolve today’s wireless transport by supporting additional, high-capacity backhaul spectrum for 5G and future 6G.”
Spectrum availability is critical for reliable and wider 5G deployment, ensuring that the benefits of the latest technology reaches more people. 5G-enabled use cases are expected to not only enhance mobile broadband services for consumers but also speed up digital transformation and automation technologies across industries such as healthcare, manufacturing, public safety, and transportation.
