Understanding RAN 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 […]
Benchmarking O-RAN performance O-RAN was big news last year, and a recent announcement from the O-RAN Alliance – one of the main bodies encouraging open RAN innovation, highlights the importance of benchmarking and testing in helping operators and others develop and get value from Open RAN deployments. Recently, the O-RAN Alliance launched a Minimal Viable […]
By combining SASE and Zero Trust, you can consistently apply and enforce security performance policies across your entire network—and give consumers the security and performance they expect. Gartner coined the term “SASE” (Secure Access Service Edge) less than two years ago, before anyone had heard of “COVID-19.” At that time, Gartner described SASE as a […]
VIAVI recently participated in, and was a Gold sponsor of, the High Speed Networking event held by LIGHTWAVE and the Broadband Technology Report. During the event, experts from VIAVI participated in several webcasts that are now available to stream for free. Before you view either, you will have to register (for free). Once you register, […]
VIAVI is pleased to announced that CRN®, a brand of The Channel Company, has named three VIAVI leaders Katy Farney, Maribel Ortiz, and Carol Ann McKeown, to the highly respected Women of the Channel list for 2021. This annual list recognizes the unique strengths, vision and achievements of female leaders in the IT channel. The […]
Network capacity planning is an ongoing process that involves continually assessing network utilization, traffic volumes, and traffic type to identify shortcomings like performance chokepoints that can affect the end-user’s experience. Without investing in capacity planning measures, organizations risk decreased employee productivity from degraded network performance, Service-Level Agreements not being met, and ultimately a poor experience […]
Advanced Upstream Blog Series Introduction In the Advanced Upstream blog series we will explore how cable operators have traditionally managed upstream bandwidth capacity planning, how market dynamics and technical innovation are driving changes, and where things are likely headed in the coming years. In this entry we will lay the groundwork for discussion of the […]
Fiber optic cables are becoming more and more important in our daily lives. They are used to transmit large amounts of information in a short period, and we strongly rely on them to maintain a reliable network connection. However, many things could potentially slow down the transmission of data, such as contaminated connectors and congested […]
If you would like a more in-depth review of what the path forward with 800G pluggable optics may look like may we suggest watching Preparing the Way for 800G: 100G Electrical and 800G Pluggable Optics. —————————————————————————————————————————————————————————————– The creation of the 800G ecosystem has begun. Alpha samples of 800G OSFP modules have been demonstrated and we […]
C-band and the role it plays in 5G Midband (or C-band) is considered the “waterfront property” of RF spectrum for 5G. It offers the best compromise between RF coverage and RF bandwidth. Per ITU’s minimum technical requirements to meet the IMT-2020 criteria for eMBB, at least 100 MHz of bandwidth will be required. For a […]
