Top 10 posts for 2019


As one would guess, 2019 was dominated by 5G and so was this blog. Surprisingly the most popular post was on Open RAN. Most likely because many people did not understand what the term meant.

People still continue to ask us when we will be changing the 3G4G name. We will change it when 3GPP (whose name is derived from 3G) and/or GSMA (whose name is derived from 2G/GSM) change their name. In short, never!

Here are the posts, from most popular to the tenth most popular, in descending order of popularity

1. A quick tutorial on Open RAN, vRAN & White Box RAN - Feb 2019

2. Displaying 5G Network Status Icon on Smartphones and Other Devices - Feb 2019

3. Prof. Andy Sutton: 5G Radio Access Network Architecture Evolution - Jan 2019

4. Theoretical Throughput Calculation of FDD 5G New Radio (NR) - Feb 2019

5. New 3GPP Release-17 Study Item on NR-Lite (a.k.a. NR-Light) - Aug 2019

6. Slides and Videos from the 1st 6G Wireless Summit - Apr 2019

7. Examples of 5G Use Cases & Applications - May 2019

8. Updated 5G Terminology Presentation - Mar 2019

9. 3GPP 5G Standardization Update post RAN#84 - July 2019

10. Exploiting Possible 5G Vulnerabilities - Oct 2019

Finally, a post from 2018 that continued to perform brilliantly this year

As you can see, 7/10 were on 5G which is probably not a surprise 😉.


In other news, this year I have done a lot more activities on 3G4G sites (thanks to support and encouragement from my current employer, Parallel Wireless). You can see links to all different 3G4G channels on top of the blog. I was also interviewed by TechPlayon and TechTrained (the similarity of name is just a coincidence). I was also named a key 5G influencer for 2017.

Back in 2011, I wrote the 1000th post and asked for your feedback. Here again, I would like to ask for your feedback, either on this post or on any posts. There are check-boxes for you to give instant feedback or you can add your comments in any of the posts.

I also mentioned in 2011 that the 3G4G blog will be touching 1.5 million page view mark, now in 2017 (10 years after the start of this blog), we have crossed over 9.5 million official page views (page views for first 3 years were not counted). Here is a snapshot of the stats for this and the small cells blog.


This has all been possible because of contributions from many individuals who share their presentations, knowledge and support my activities in many different ways. Thank you!

Finally, I can make mistakes too so please feel free to correct me anytime you spot me saying something wrong. I don't mind 😊

1000th Blog post and I want your feedback


I started the 3G4G website 7 years back and in the next few years realised that maintaining website is very time consuming job. As a result I started the blog on the 3G4G website. Its been nearly 4 years since I started blogging. Initially I blogged on the 3G4G website and then moved to blogger. Over the time, the blog has become ever so popular and I regularly keep getting between 40,000 and 50,000 page views per month. In the next few months, I will touch the 1.5 million page views mark.

All this sounds great but I have not seen enough feedback and/or comments from you the readers. Some months back I added the feedback box at the bottom of the posts that you can use to provide me a quick feedback indicating if you found this post useful or not useful and if you would like more like these but I hardly get more than 1 or 2 feedbacks every post. The only one where I got some decent feedback was on the Dilbert post here. In the blog stats that was added last year by blogger, I can see that some of the posts even get good amount of views but not enough feedback. For example LTE-A UE categories has over 7000 views but just 3 very useful feedback. Another one on comparison of HSPA+ and LTE has over 4000 views since last May but the feedback is still not enough.

Over the last few years, a lot of my posts are being copied by others in entirety. Some of these blogs give credit to me but do not link my blog. Some of them do not even give me credit or link to the blog. In fact to stop some of these things, I started putting 'via 3g4g.blogspot.com' in the images and then I realised that some of these blogs, remove this and put the pictures up. Take for instance this post from TelecomDE, this blog post is copied from my blog post here. I created the picture from a presentation and that was from Huawei, so I added the Huawei logo in the picture. As you can see the Huawei picture is there but the 'via 3g4g.blogspot.com' has been removed. There are many instances of such things and I would like to thank some of my blog readers who point me out these things.

With my schedule being already extremely busy, I sometimes spend early mornings or late night, creating new blog posts with the things that are happening or about to happen in the wireless/telecom world. I think my blog covers some unique topics and I always add some useful pictures and images as it is said that 'A picture is worth a thousand words'. I would like to receive feedback from you, dear reader, on if you find this blog useful, how do you find it useful, what things you like most, what things you like least, how do you propose to change it for better.

I do get lots of personal mails from people saying how useful the blog and the website have been for them for Job hunting, etc. So If you found the Blog or the Website useful and you are a Linkedin user, can you please recommend the 3G4G website on Linkedin for me.

I will be deciding in the next few weeks, If I continue blogging and your feedback certainly will help. In the meantime, you can always follow me on Twitter where I am always on lookout for the latest in the field of wireless telecoms.

The silent heroes of the wireless world

Often you will hear about some famous people from certain organisations who speak at conferences and meetings but there are often in the background many people who labour to ensure that reports, documents, presentations and technology are completed without problems.

Last Friday, I met up with some old colleagues who are these silent movers and shakers in our mobile industry. Often behind multiple monitors and pile of documents, these people work on the cutting edge future technologies. It was nice to know that they do read and refer to my blog from time to time and find it useful.

I should also like to mention the people who often mail me to thank me for the blog and the 3g4g website. I do quite often bump into people who know me for my work but dont know me personally. Sometimes they do get a bit surprised because my HQ (humour quotient) is very high. I have a jokelist active since 1999 and even though I dont get enough time to post jokes I do make it a point to keep it alive.

I am fortunate enough to learn a lot from such people, as knowledge is limitless and there is always something everyone can contribute as they may know it much better than others.

So please feel free to say hello to me when you come across me in any conference, presentation, party or even interviews. Its always good to know people.

  • In the quietest month (Dec.), the combined page views were around 75,000
  • The 3G4G blog has page views from 22,000 (Dec) to 35,000 (Oct).
  • The popular pages of the Website are FAQ, LTE and LTE-Advanced.
  • The popular pages of the blog are HSPA+ vs LTE, OFDM/OFDMA Difference and F-DPCH.
