FUTURE-PROOFING 5G ARCHITECTURE WITH OPEN-RAN

Article | May 19, 2021

The RAN (Radio Access Network) architecture for mobile networks includes a remote radio unit (RRU) located at the top of a cell tower, which communicates with a baseband unit (BBU) at the base of the tower. The hardware and communication interfaces are owned by a specific vendor, and its software-driven functionality is tightly coupled within the hardware. Traditionally, this has worked well for mobile network operators (MNOs). However, there are several drawbacks to consider – for instance, upgrading or changing the wireless network demands physical hardware replacements throughout the network, which is cost-inefficient, labor-intensive, and time-consuming. Furthermore, the equipment and interfaces that connect the hardware are owned by the vendors that originally supplied them, which locks MNOs into existing relationships with them.

How to keep 5G data secure with software probes

Article | May 19, 2021

Enhanced security and privacy are cornerstones of 5G Core, but service providers still need to be able to capture quality, actionable data to secure the end-customer experience. Specifically, I’m referring to the data needed to perform troubleshooting, monitoring, customer care and analytics for marketing campaigns. But can this be done in 5G Core using traditional probing methods, without breaching security? The 3GPP standardization for 5G considers enhanced security to be an essential network component. Imagine, for a moment, that we live in a world where it’s common for open heart surgery to be conducted remotely, and I’m sure you’ll agree. The need for a secure, reliable network has resulted in the introduction of a new Service Based Architecture (SBA) that utilizes encrypted interfaces between network functions (NFs). Traffic between network functions is deployed in a cloud native 5G Core Kubernetes node and will not be visible outside the cluster, meaning traditional probing solutions are unsustainable.

AT&T expands its 5G network to 22 new cities and introduces mmWave 5G+ in some markets

Article | May 19, 2021

5G on mmWave frequencies is the fastest offering, but it has pretty severe range limitations. This is the same 5G technology that Verizon is using, and it requires customers to be in very specific locations to connect to it. But when you can get it, AT&T promises speeds up to 2Gbps. Only the Galaxy S20+ and Galaxy S20 Ultra support mmWave on AT&T and not the carrier’s variant of the Galaxy Note 10+ 5G. The company’s mmWave network, which they are calling “5G+,” is available in 35 cities. Last month, AT&T expanded its coverage of sub-6GHz 5G to more cities. This week, they are adding 22 more markets to the list, bringing the total number up to 80. Those markets include:

Security in digital banking is all about convenience and trust

Article | May 19, 2021

The increasing use of mobile applications and digital payment services has not only paved the way for new banking models, but also highlighted the importance of user experience in digital banking. Banking applications are now developed completely on cloud, support multiple platforms, and use AI/ML extensively. Security, a critical aspect of digital banking, has transformed with innovative capabilities like self-service identity verification, passwordless access, risk-based multi-factor authentication (MFA), behavioral analytics, and encryption capabilities. The underlying reason for developing the above-mentioned capabilities is to provide consumers with a secure banking experience, where they can access their financial data without fear and conduct transactions with ease. For the bank employee, it is all about working with the latest digital services and securely accessing them from anywhere. It is important to understand that user experience, be it consumer or workforce, is all about providing convenience and establishing trust. Only then can a financial institution remain ahead of the competition.
