5G NR Synchronization Signal Block (SSB)
November 22, 2020

In previous cellular technologies (LTE, LTE-M, NB-IoT), cell-specific synchronization and reference signals were used. Always-on reference signals were spread over the entire spectrum for precise channel estimation. 5G NR is a completely new approach regarding cell-specific signals. 5G NR only broadcasts a minimum amount of cell-specific signals with a known sequence that can be measured […]

Why do MNOs need to shift to DSS?
November 8, 2020

DSS: Dynamic Spectrum Sharing DSS technology has been introduced by the industry to enable 5G services to be delivered in LTE networks to accelerate the availability of 5G services. Traditionally mobile network operators had two main options to deploy new cellular technologies, as follows: Spectrum re-farming, which re-uses the spectrum licensed by mobile operators migrating […]

What is the difference between vRAN and Open RAN?
October 25, 2020

The mobile industry is currently discussing Virtualized RAN (vRAN) and Open RAN, but it is vital to distinguish between these two concepts because they represent different approaches. These two initiatives serve different purposes that may often overlap. From a high-level perspective, the two initiatives are described below • vRAN These networks decouple software from hardware […]

5G Uplink Challenge!
October 21, 2020

One of the big challenges nowadays in 5G technology is the Uplink or UL. Historically, most mobile network traffic has been on the downlink since users have long craved high data speeds to download their favorite videos. With the new normal, and the increase in video conferencing, the uplink traffic increase by up to 40 percent, putting a significant strain on the uplink as per […]

What is the importance of the “Virtualization”?
July 2, 2020

Introduction Simply put, virtualization is an idea whose time has come. The term virtualization broadly describes the separation of a resource or request for a service from the underlying physical delivery of that service. With virtual memory, for example, computer software gains access to more memory than is physically installed, via the background swapping of […]
