How many Cell Sites and Base Stations Worldwide?

I wrote a blog post on this topic nearly three years back on the Operator Watch Blog here. That post is very handy as every few months someone or other asks me about this number. Here is a slightly updated number, though I am not confident on its accuracy. 

Gabriel Brown, analyst at Heavy Reading shares this chart above in the annual online Open RAN Digital Symposium. Based on the chart above, there are 7 million physical sites and 10 million logical sites. As there are many sites hosting infrastructure from multiple operators, the number of logical sites are more than the number of physical sites.

Again, most of the sites have distributed RAN (D-RAN) so there may be one or more base stations (baseband unit or BBU) and each base station can serve one or more radios. See links at the bottom for tutorials on these topics.

China Tower had nearly 2.1 million telecom towers installed with 3.36m tower tenants at end of 2022. An MIIT minister said that China's operators will deploy 600k 5G base stations in 2023, taking total to 2.9m.

The number of 5G radios in India just crossed 100,000 according to latest data released by the Department of Telecommunications. A base station generally manages multiple radios so not sure how many base stations would be there for 5G and even for older Gs.

In South Korea, according to the Ministry of Science and ICT and the mobile communication industry, as of December 2021, had 460,000 5G wireless stations of which, base stations accounted for 94% of the total, or 430,000 units, while repeaters only accounted for 30,000 units, or 6%.

Light Reading reported in September 2022 that there are nearly 419,000 cell sites across the US, according to the newest figures from CTIA. 

China and USA are roughly the same size so you can see how China is ensuring their mobile networks provide the best QoE. It should also be noted that the population of China is over four times that of the USA. On the other hand, India and China have the same population but India is one third the size of China roughly.

Different Types of RAN Architectures - Distributed, Centralized & Cloud


I come across a question relating to the different type of RAN architectures once per month on an average. Even though we have covered the topic as part of some or the other tutorial, we decided to do a dedicated tutorial on this.

The video and slides are embedded below

As always, feedback and comments welcome.

5G New Radio Standards and other Presentations


A recent Cambridge Wireless event 'Radio technology for 5G – making it work' was an excellent event where all speakers delivered an interesting and insightful presentation. These presentations are all available to view and download for everyone for a limited time here.

I blogged about the base station antennas last week but there are other couple of presentations that stood out for me.


The first was an excellent presentation from Sylvia Lu from u-Blox, also my fellow CW Board Member. Her talk covered variety of topics including IoT, IIoT, LTE-V2X and Cellular positioning, including 5G NR Positioning Trend. The presentation is embedded below and available to download from Slideshare





The other presentation on 5G NR was one from Yinan Qi of Samsung R&D. His presentation looked at variety of topics, mainly Layer 1 including Massive MIMO, Beamforming, Beam Management, Bandwidth Part, Reference Signals, Phase noise, etc. His presentation is embedded below and can be downloaded from SlideShare.

Base Station Antenna Considerations for 5G

I first mentioned Quintel in this blog three years back for their innovations in 4T8R/8T8R antennas. Since then they have been going strength to strength.


I heard David Barker, CTO of Quintel at Cambridge Wireless event titled "Radio technology for 5G – making it work" talking about the antennas consideration for 5G. There are quite a few important areas in this presentation for consideration. The presentation is embedded below:

#CWHeritage Talk: The History of Synchronization in Digital Cellular Networks


CW (a.k.a. Cambridge Wireless) held a very interesting event titled 'Time for Telecoms' at the Science Museum in London. I managed to record this one talk by Prof. Andy Sutton, who has also kindly shared slides and some other papers that he mentions in his presentation. You can also see the tweets from the event on Twitter.

The video playlist and the presentation is embedded below.






The papers referred to in the presentation/video available as follows:
