Telecommunications company Ligga is set to improve bandwidth and accelerate 5G deployment in its territory. To do just that, the Brazilian telco is launching a proof of concept with smart luminaires by Omniflow® that will host small cells and also bring other business opportunities for the telco. In this video we interview Vitor Menezes, Director of Regulatory and Institutional Affairs at Ligga, and Pedro Ruão, CEO of Omniflow, to discuss the project, why Ligga chose this smart attachment instead of just a regular small cell, and what other sources of revenue this project could bring to the telco.

Podcast 59: TADSummit Innovators, Tim Panton, Pipe, There's no such thing as #5G https://lnkd.in/dnVMPvAg Tim Panton is the co-founder of pi.pe, and a TADSummit and TADHack regular. The last time we talked was about the peer-to-peer baby monitor technology pi.pe licensed to a baby monitor company. The learning from that product is customers are not that concerned about the security and privacy of their baby monitors. Tim pointed to the success of the cloud providers in giving the illusion of security and privacy. The story is also complex as consumers need to understand how the product is inherently secure and private. Plus we've all become numb to yet another security breach from a large consumer brand. We've even become numb to the spamming and scamming of the elderly resulting in many loosing their life savings. Back to more uplifting topics. Tim's been working on an #RTC (Real Time Communications) project with racing cars, providing low latency 2 way video communications for driver training across many circuits around the world. Some of his learnings are, drivers do not talk that much, and the big one, there is no such thing as 5G! What Tim means by that is 4G is always required for 5G to work, unless it's standalone, 5G is a bag of technologies, frequencies with variable capabilities, and he's never come across 5G Standalone, yet. And currently 5G appears optimized for YouTube streaming, not low latency communications. One of the reasons Tim uses 5G rather than 4G is the additional capacity gives enough headroom for video to work reliably for a car travelling at 250 kmph. Tim targets 350 ms latency, he runs his own WebRTC stack which gives him lots of control for fine tuning performance. While driver training for race cars is a high value niche, he's also looking at other vertical applications such as remote supervision for drones and 'autonomous' cars. Another interesting niche is ensuring betting events have as close as possible to in-person experience so betting is fair. He's not looking for funding, rather partners that can use his close to real-time communications technology to solve regulatory or business operations issues. Tim also highlights he uses a tourist SIM for this application, the cost per MB for #IoT is orders of magnitude too high. I've heard this from numerous IoT innovators. Matthew D.

#5G is a disruptive driver that will be at the center of innovation and economic and social development of countries over the next decade. Last week, head of Ericsson Portugal, Juan Olivera Urquijo, attended the 33rd national APDC Congress in Portugal. In his keynote, he called on national and European political and business decision-makers to: 💡 Address the delay in the rollout of 5G in Portugal and Europe compared to other regions; 💡 Industrialize through a strong commitment to technology and innovation; 💡 Increase technology penetration in the 27 EU states; 💡 Change existing regulatory positions in light of a too fragmented market. Also, in an article published in Jornal de Negócios (content in Portuguese), Juan Olivera reinforces Ericsson's position on these issues and calls on Europe to take measures to avoid becoming irrelevant in the current context. https://lnkd.in/eYMDhHWT

Nokia is proposing #InLine L1 acceleration that increases the efficiency and overall performance of the #vDU, helping to close the performance gap and make Open RAN a reality. 📗Hardware acceleration technology is a critical element in Open RAN/Cloud RAN/vRAN performance as a critical factor has been the performance of layer 1 computations within the virtualized Distributed Unit (vDU) of the Open RAN architecture. 📗There is another approach called #look_aside which leverages a layer 1 accelerator to conduct #only a subset of layer 1 functions, specifically for Forward Error Correction (FEC). As per Dell Technologies, The look-aside approach creates a lot of inefficient back-and-forth communications between the server’s central processing unit (CPU) and the FEC accelerator card. 📗In addition, since the FEC accelerator card #only does a subset of layer 1 processes, the server CPU must process some of the layer 1 computations, which it is #not optimized to handle. 📗As per Dell, the look-aside approach is a primary cause for the performance gap between traditional RAN and Open RAN systems.

NEW 6G LOGO I see today on the 3GPP website that the new 6G logo has been approved https://lnkd.in/d_pFnHuy The continuous search for improvement, the relevant technological challenges, the involvement of many actors including Standardization Bodies, Vendors, Operators, Vertical Markets for effective interoperability between Network Elements of which we all enjoy the advantages in the world of Mobile Telecommunications are some of the reasons that make me love the world of telecommunications. However, I would say that it is undeniable that after the peak of hype relating to 5G, the period of disillusionment with this technology is taking hold and the shape of the Hype Cycle is risking being at its minimum value. The reasons for this discouragement are the delays in some of the promises of this technology and one of the reasons, in my opinion, was the delay in the implementation of SA (Standalone) solutions, the lack of an effective and effective Network Slicing e2e (also this is not possible in the case of 5G NSA), an energy efficiency that is still not satisfactory and other reasons. It is true that 5G advanced (3GPP Rel.18) introduces notable improvements but it is undeniable that outside the esoteric world of experts there may be the temptation to wait for 6G which should probably come out as specifications in Rel.21, which means end of 2028 and commercially in 2030. In my opinion it will therefore be appropriate to highlight the advantages of 6G but pointing out that not all (and indeed a small part) will be present from the beginning and that now we still need to focus on 5G and 5G advanced which at least until 2035 will be the actual technology in the field and mature enough to appreciate his abilities. What do you think? And post scriptum, I like the 6G logo, more than that of 5G and LTE, more modern, with a reference to the infinity symbol which makes it very dynamic. #6G #5G #3GPP

VoLTE Roaming is still an unclear topic from an urgency perspective. If we look at this insight from Kaleido Intelligence, we can realize that the VoLTE agreement (inbound or outbound) is still #SLOW. Only 175 operators in 80 countries launched VoLTE roaming till Q2 2023. 📗 The growth of #5G has put pressure on MNOs to free up the current spectrum so it can be dedicated to supporting this new network deployment. So older networks like 2G and 3G are being phased out to reallocate spectrum and save costs associated with equipment and resources. However! 📃 We can understand the risk of shutting down these older technologies like #customer_satisfaction from non-VoLTE devices, especially for the roamers. At least the roamer should find the connectivity that matches his device capabilities. 📃 Another point is that this will have an impact on many operators’ roaming business, potentially resulting in a loss of #revenue for those that drop 2G/3G support, and even a lack of efficiency and security on the IoT support side of this equation, as some companies continue to utilize older networks. 📗Going to 5G NSA and SA, the roaming topic is non-mature! 📃 5G Roaming, 5G NSA roaming is available in 60+ international markets, with the first set of 5G SA roaming commercial agreements expected in 2024.

5G Network Performance Monitoring with KPI xApp In this video we showcase the deployment of a KPI monitoring xApp on a complete 5G setup featuring a Core, simulated gNB, UE, and Near RT RIC. We begin by installing SWIG, a versatile compiler for integrating C/C++ with languages like Python, Java, and Ruby, among others. After building the SWIG binaries, we configure our environment checking for compatible GCC versions and Docker Compose versions. For this deployment we used 5G Core and RAN repository from OpenAirInterface. We then compiled and installed the FlexRIC module, essential for handling E2AP and KPM encoding. After the Near RT RIC was deployed, E2 setup request was initiated. Finally, the KPI monitoring xApp was activated, successfully exchanging traffic between the UE and network, confirming smooth connectivity and monitoring. This setup is a step towards enhancing 5G network performance monitoring with real-time insights.

𝗣𝗹𝗶𝗻𝘁𝗿𝗼𝗻 𝘃𝘀. 𝗦𝘂𝗿𝗳 𝗧𝗲𝗹𝗲𝗰𝗼𝗺: 𝗥𝗲𝗴𝘂𝗹𝗮𝘁𝗼𝗿 𝗮𝗽𝗽𝗲𝗮𝗹𝘀 𝗰𝗼𝘂𝗿𝘁 𝗱𝗲𝗰𝗶𝘀𝗶𝗼𝗻 - 𝘁𝗵𝗲 𝘀𝗮𝗴𝗮 𝗰𝗼𝗻𝘁𝗶𝗻𝘂𝗲𝘀 - 𝗻𝗼𝘄 𝗶𝗻 𝗶𝘁𝘀 𝟳𝘁𝗵 𝘆𝗲𝗮𝗿 The case between the mobile virtual network enabler (#MVNE) Plintron and the Brazilian aggregator (#MVNA) and enabler (MVNE), Surf Telecom goes into yet another round. Following an injunction last week from the Federal Court, ordering Brazil's telecom regulator Anatel to grant consent for the minority shareholder Plintron to take control of Surf Telecom, Anatel has decided to file an appeal. Anatel's reason for denying Plintron to take control of Surf are risks to business continuity and that ultimately the consumer will be harmed. You can read much more about Surf vs. Plintron here: https://lnkd.in/gnYcNQrB In its appeal, Anatel presents two arguments. Firstly, it recalls that Plintron shut down the platform in 2020, affecting Surf's #MVNO partners and subscribers, including the Post office MVNO. “For eleven days, an institution of the greatest importance for Brazil, the Post Office, had restrictions on the services provided. In addition thousands of consumers were harmed at the height of the Covid-19 pandemic," writes the prosecutor in the appeal. The agency justifies its refusal to agree to change control of Surf with the argument that this would put Brazilian consumers at risk. The second argument is that the Federal Regional Court can't force it to grant consent, and that this would represent an invasion of jurisdiction. “It is up to the Judiciary to control administrative acts in terms of legality (…) In the case at hand, however, an invasion of the powers of the Regulatory Agency is claimed, as the Judiciary would be directly interfering in regulation which is the responsibility of Anatel, under the terms of the Federal Constitution”. It is worth noticing that the case between Plintron Holdings, based in Singapore, and the Brazilian company Maresias Participações (controlling company of Surf) has been in litigation for seven years, with decisions going left and right. It now seems that the next step could be the Supreme Federal Court. Surf has more than 50 MVNO partners operating in Brazil and has just launched its own MVNO service in the U.S last week. https://lnkd.in/gGZMcMZb

Court overturns injunction obtained by Plintron against the MVNA/MVNE Surf - to prevent "irreparable damage" until a definitive decision is made The Sao Paulo Court of Justice has suspended the effects of the arbitration award that allowed the Singaporean company Plintron to take control of the Brazilian mobile virtual network aggregator (#MVNA) and enabler (#MVNE) Surf Telecom, after an appeal by SURF Telecom. To justify the decision, the judge cited "the risk of irreparable damage resulting from the losses that would be caused, especially given the reported risk of transfer of corporate control of the appellant Surf, with an impact on consumers and the national telecommunications system". The judgment, however, is not definitive. It seeks to avoid damages until the case has its merits analyzed by the Court. The suspension of the arbitration award is valid until the admissibility examination of the claim or until its judgment, in case the appeal is admitted. Plintron is also required to present counter arguments to the special appeal filed by Surf. In addition, Surf Telecom is seeking the reversal of the arbitration decision that gave Plintron rights over the company. The operator argues that the result of the arbitration went beyond the limits of what could be decided there, in particular, by increasing the number of shares in the company and diluting one of the third-party shareholders. The measure would not be authorized by the Investment Agreement and diluted the shareholding of Surf Group Holdings Limited (SGHL). The failure to recognize SGHL as an independent party, is also considered as a potential offense. https://lnkd.in/gUmGZtER
