5G Top-10 Misconceptions


Here is a video we did a few weeks back to clear the misconceptions about 5G. The list above summarizes the topics covered.



The video is nearly 29 minutes long. If you prefer a shorter version or are bored of hearing me ðŸ˜œ then a summary version (just over 3 minutes) is in 3G4G tweet below.


The slides can be downloaded from our Slideshare channel as always.

As always, we love your feedback, even when you strongly disagree.

5G NR Radio Protocols Overview


3GPP held a workshop on 5G NR submission towards IMT-2020 last week. You can access all the agenda, documents, etc. on the 3GPP website here. You can also get a combined version of all presentations from the 3G4G website here. I also wrote a slightly detailed article on this workshop on 3G4G website here.

The following is nice overview of the 5G Radio Interface protocol as defined by 3GPP in NR Rel.15 by Sudeep Palat, Intel. The document was submitted to the 3GPP workshop on ITU submission in Brussels on Oct 24, 2018.



The presentation discusses NR radio interface architecture and protocols for control and user plane; covering RRC, SDAP, PDCP, RLC and MAC, focussing on differences and performance benefits compared to LTE.  RRC states and state transitions with reduced transition delays are also discussed.

Telefonica, Mayutel, Facebook & Parallel Wireless: Connecting the Unconnected in Peru (#InternetParaTodos)


Back in summer I wrote about how Telefonica and Parallel Wireless(*) are on a mission to connect 100 Million Unconnected and then followed it by a blog post with information from Patrick Lopez, VP Networks Innovation @ Telefonica about how Telefonica is using Big Data, Machine Learning (ML) and Artificial Intelligence (AI) to Connect the Unconnected.

In the Facebook TIP Summit last month, Roger Greene, Rural Access Lead, Connectivity Ecosystem Programs, Facebook talked to Juan Campillo, Internet Para Todos Lead, Telefónica & Omar Tupayachi, Founder & CEO, Mayutel about how they are connecting the unconnected. The discussion embedded below, starts with a very nice video about how connectivity is making a difference in Peru. In fact that video inspired me to do this post 😊.

Mayutel was described as Peru's first rural operator. It was founded in 2015 and works in over 150 areas. It has 25 employees.

During the discussion some interesting points were discussed like planning, the reason its important is that if you dont do proper planning and analytics, you can use small cells instead of macros and vice versa. Also, some solutions are worth trying in the field as its only when deployed, it can be tested in real-world scenarios.

Connectivity is very important for the rural people in Peru, like every other country. Approximately 4 million Peruvians have only got access to 2G technology. It would help if they have access to have 3G & 4G too. It not only helps connect the people on the move to their loved ones back home, it also helps small businesses who reply on messaging group communications to solve their issues and ask for help & advice.
Due to the Open RAN approach, the cost of deployment has reduced by 50-70%. Mayutel mentioned that they were able to deploy a site at 1/10th the cost it would normally take. This was all thanks to the open approach where their engineers can learn how to deploy the complete solution. It was vital to use local help not only in terms of knowledge but also in terms of manpower.

There were some good lessons and learning but in the end for this to scale more operators need to become part of the Telecom Infra Project and make this successfully happen.




Here is another video from Parallel Wireless on their deployments in Peru.
