Time Synchronization is Critical in 5G Open RAN Network
February 20, 2023

In order to meet the 5G network timing requirements, there is a significant challenge. The challenge is 5G performance requirements driving precise timing needs from cloud to edge. The legacy proprietary solutions rely on high-cost, purpose-built appliances, and specialized network interface cards. 5G deployments demand high timing synchronization across the network and affordable infrastructure costs. […]

What is 5G Security Edge Protection Proxy (SEPP)?
January 12, 2023

The Security Edge Protection Proxy (SEPP) is a proxy that sits at the perimeter of the PLMN network and enables secured communication between inter-PLMN network messages. It protects the home network and acts as a security gateway. Located at the edge of the network, it polices connections between the home network and the visited networks. […]

Are 5G and WiFi6E Friends or Competitors?
January 10, 2023

When it comes to questioning, Are 5G and WiFi6E friends or competitors, I prefer to answer “They Should be Friends” 5G (cellular technology) and Wi-Fi 6E (wireless LAN) use similar technical methodologies to provide high-end user experiences. Both 5G and Wi-Fi 6E are the latest versions of their respective technologies. Two common approaches being used […]

As per Statista, The number of global unique mobile subscribers is expected to grow by 160 million from 5.7 billion subscribers in 2020 to 5.86 billion in 2025 and this massive data growth means more expectations regarding the data speed, capacity, and customer experience.   4G technology provides the network architecture to transmit huge amounts […]

5G is Not Hazardous To Your Health
September 26, 2022

All generations of mobile phone technology, including 5G, take the same familiar underlying approach. A mobile network consists of a nationwide grid of cell sites. These sites feature transmitters that generate radio waves, which are received by a mobile phone’s antenna.  The radio waves generated by mobile networks, TV stations, and radio stations are not […]

3GPP Architecture for 5G NR
September 21, 2022

As per 3GPP, The gNB is divided into two logical functions: the CU and DU. The DU is the baseband unit in a 5G RAN. It handles layer 1 and layer 2 processing and fulfills critical functions such as coding/decoding, scheduling, MIMO processing, and beamforming. It makes sub-millisecond decisions about allocating radio resources within a […]
