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 […]

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 […]

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 […]

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 […]

The core of mobility management in 5G NR is very similar to the one in 4G LTE. As specified by 3GPP Rel. 15, mobility in mobile networks is divided into RRC_IDLE mobility, RRC_INACTIVE mobility, and RRC_CONNECTED mobility. RRC_IDLE and RRC_INACTIVE state in which UE does not have any established RRC connection. RRC_CONNECTED means that UE […]
