Before start talking about DSS or Dynamic Spectrum Sharing, let’s address the problem first and how DSS can solve it. As we know that 5G can support newly released frequency bands for use – such as the C-band (3-5 GHz) and millimeter wave (mmWave) band (24-40 GHz) – are higher than the current 4G frequency […]

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 […]

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 […]

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? 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 […]

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 […]

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 […]

Some friends asked me, Should we have a 5G good data rate when seeing 5G Icon on our phone? Mmmm… My answer should be Yes, However it’s the not right answer as there’re many technical items we need to discuss first before answering this question.  Let’s remember this famous incident/debate from US company AT&T when […]

In June 2018, as 3GPP announced that the standalone (SA) standards have been frozen, the standardization of 5G Core (5GC) is complete. 5G network commercialization has begun and the world-wide mainstream operators are dedicated to 5G network construction. According to 5G deployment options, 5G voice solutions not only include the target solution Voice over New […]

  5G New Radio (NR) 3GPP is defining 5G NR in Release 15, with an initial release for a non-standalone operation scheduled for March 2018 and a full release for a standalone version scheduled for September 2018. 5G New Radio Release 15 Focus: 5G NR Release 15 features: Ability to operate in any frequency band, […]

The Gulf Countries (UAE, Saudi Arabia, Qatar, Kuwait, Bahrain, and Oman) are the front runner in the 5G Race. They started to think of 5G as early as Mid-2019. Use Cases: The main initial two uses cases are eMBB (Mobile) and FWA (Fixed Wireless Access). 5G Spectrum Band: The 5G Spectrum Auction is in two […]
