What is the difference between Traditional RAN and Open RAN?
April 16, 2021

Open and virtualized RAN, Open vRAN refers to a disaggregated approach of deploying virtualized mobile networks by using open and interoperable protocols and interfaces, implemented over a common propose hardware in a multi-vendor software environment, allowing increased flexibility over traditional RAN architectures., aiming to provide OPEX and CAPEX savings while fostering innovation. Traditional RAN Protocol […]

What is the difference between 4G Core and 5G Core?
April 15, 2021

In LTE Core Network, all data plane traffic must go through a single node type called Packet Data Network Gateway (P-GW). This centralized architecture is advantageous in terms of operation and management. Yet, it could potentially pose a severe limitation when there is a huge amount of backhaul traffics in 5G. The following figure illustrates […]

Functional Split Options for 5G Networks
April 5, 2021

Functional Split Options for 5G Networks As network architects work to meet the 5G challenges of increased traffic and data flows, a fundamental question is how much intelligence to put near the antenna versus at the DUs or CUs. Mobile Network Operators (MNOs) as well as industry-standards groups, such as the 3GPP, IEEE, Telecom Infra […]

The Importance of RAN Intelligent Controller (RIC) in O-RAN Architecture
April 1, 2021

The main motive for the RAN Intelligent Controller (RIC) is to bring software-defined controllability to RAN to increase system performance as on the path towards 5G, with network densification, and availability of different types of spectrum bands, it is increasingly a more difficult task to optimally allocate radio resources, implement handovers, manage interference, balance load […]

How does O-RAN Alliance Open Telecom Interfaces?
March 14, 2021

The O-RAN Alliance is the main driver of the OpenRAN concept, especially the efforts to standardize interfaces, in addition to the TIP. Founded in 2018 by AT&T, China Mobile, Deutsche Telekom, NTT DOCOMO, and Orange. The O-RAN Alliance’s goal is to foster the development of reference designs and standards such that current and future RANs […]

Function Migration from 4G to 5G
March 10, 2021

5G shouldn’t be seen simply as the next generation of mobile communications. It’s a smart ecosystem that’s ready to catch new innovations and highly customized services. 4G to 5G Interworking 4G LTE and the 5G networks will continue to interwork for a number of years. This is why it’s essential to:  Support a seamless handover […]

Why do MNOs struggle to shift to Open RAN?
March 7, 2021

Why do MNOs struggle to shift to Open RAN? I know many MNOs are struggling to shift their RAN strategy to OpenRAN in their 5G Roadmap due to many reasons like they can not get away from their monolithic supply chain from the big vendors. Also, there’re some interfaces that are still NOT open even if these […]

5G Voice over New Radio (VoNR)
March 3, 2021

VoNR is IMS based voice services that use 5G as the access network (as opposed to LTE and VoLTE) Introduction Voice over New Radio (VoNR) is the IP Multimedia System (IMS) based voice calling services that use the 5G network for its source of Internet Protocol (IP) voice processing. The New Radio network communication is […]

What Drives QoE of a Service?
February 27, 2021

The accurate benchmarking and scoring of networks that cover large geographic areas requires careful consideration of a number of factors. These include the technology used, the extent of coverage offered, mobile device evolution, customer population distribution, network usage, and tariff offerings.  Best QoE [Quailty of Experience] in daily life for a customer guarantees satisfaction and […]

What Determines The Capacity Of A Network?
February 17, 2021

In the early 1900’s two researchers working independently derived a relatively simple equation that serves as a Moore’s Law for the wireless industry: the Shannon- Hartley theorem. This theorem gives an upper bound to the amount of information that can be transmitted over the wireless channel where the individual channel capacity is dependent on only […]

What is RAN Disaggregation?
February 16, 2021

In the cellular network, RAN provides wide-area wireless connectivity to mobile devices. Towards this end, it conducts two fundamental tasks: It converts IP packets to Physical Layer packets suitable for transmission over the time-varying mobile channel using packet and signal processing techniques. It conducts Radio Resource Management (RRM) control to determine how best to use […]
