5G+ and 5GA Icon (Pictogram) in New Smartphones

As 5G matures, new icons are appearing on smartphones to distinguish faster or more advanced connections. Some of the latest 5G smartphones around the world have started showing new icons such as 5G+ and 5GA. Interestingly, in Japan these are referred to as pictograms.

A long time ago, we looked at how Swisscom described its 5G rollout as 5G-wide and 5G-fast. Today, Swisscom uses the 5G+ icon to represent what it previously called 5G-fast. In its annual report, Swisscom explained:

5G (and 5G+) is the latest generation of mobile technology. Compared to 3G and 4G, it provides even more capacity, very short response times, and higher bandwidths. 5G technology plays a major role in supporting the digitalisation of the Swiss economy and industry. Swisscom differentiates between 5G-fast (narrower coverage up to 2 Gbit/s and more) and 5G-wide (Switzerland-wide 5G coverage with up to 1 Gbit/s). 5G-fast is also known as 5G+. Both variants are more efficient than their predecessor technologies with respect to energy consumption and use of electromagnetic fields.

Japan has only recently transitioned to using 5G+. A Google-translated page from NTT Docomo explains it as follows:

In areas where 5G communication is possible, the RAT display on standby will be "5G." On the other hand, during communication, the RAT display will be "5G+" for 5G communication using wideband 5G frequencies (3.7 GHz, 4.5 GHz, 28 GHz), "5G" for 5G communication using 4G frequencies, and "4G+" for LTE communication.

There are also footnotes clarifying that the display depends on the device, the bands supported, and the area of use.

From this, my understanding is that in newer devices the 5G+ icon is primarily used to indicate speed and capability, regardless of whether the connection is Standalone (SA) or Non-Standalone (NSA) 5G. KDDI is following the same approach, as explained on its own support pages.

Last year we looked at what iPhone icons meant. In iOS 18, 5G+ indicated that the phone was connected to mmWave. In iOS 19 this hasn’t really changed, although I have been told that it depends on the operator whether they choose to display 5G+ when the device is camped on higher-speed mid-band 5G.

Samsung Galaxy smartphones display two or three types of icons, as shown in the picture at the top. While the meanings are not entirely clear, Samsung’s user guide for Android 15 explains them as:

• Filled square: “5G network connected”, which I interpret as being connected to a 5G Standalone network.
• Transparent or outlined square: “LTE network connected in LTE network that includes the 5G network.”, which I interpret as 5G NSA.  
• I did not find a reference to the unboxed 5G icon in this manual.

Finally, the OnePlus 13 in India has started displaying the 5GA icon. Since Jio only operates a 5G Standalone network, it is possible they have upgraded the network and device to use the Release 18 ASN with some new features. This allows them to market it as 5G-Advanced, thereby justifying the 5GA icon.

If you have noticed something different in your country or region, or have another interpretation, I would love to hear more.

Mobile Network Infrastructure Sharing in Japan over Electric Power Infrastructure

On the 3G4G Small Cells Blog, I have written about the Autralian operator Telstra trialing small cells on Tasmania’s power poles to fix mobile black spots. This looks like a similar initiative in Japan but at a much larger scale.

KDDI have an announcement in Japanese here but Rakuten has one in English:

TEPCO (Tokyo Electric Power COmpany) Power Grid, Incorporated, KDDI CORPORATION, SoftBank Corp. and Rakuten Mobile Network, Inc. announced that the four companies have reached an agreement to collaborate on trials of base station site and equipment sharing utilizing TEPCO PG’s utility poles and other electric power infrastructure, ahead of the introduction of 5th generation mobile communications systems (5G) in Japan. The trials are due to be begin in the first half of FY2019.

5G utilizes high frequency bands in order to enable higher speeds and greater capacity. As a result, the number of base stations required for 5G is expected to be larger than for 4G. The growing number of base stations not only creates difficulties in securing installation locations, but also calls for consideration on the impact too many antennas and other equipment might have on the landscape.

TEPCO PG has been working together with KDDI to explore the shared utilization of utility poles and other electric power infrastructure and base station equipment between mobile network operators, and as preparations are now complete, the companies are set to begin the trials using actual equipment.

The trials, which SoftBank and Rakuten Mobile Network are also set to join, aim to verify the feasibility of location and equipment sharing between mobile network operators. Specifically, the trials will evaluate the equipment, layout, workability, serviceability and the level of radio interference resulting from sharing the antenna for base station installations on utility poles. There are also plans to expand the number of companies participating in the trials to include other organizations planning to utilize 5G in the future.

Sharing utility poles among a number of mobile network operators makes it possible to flexibly build out base stations in urban areas and rapidly launch services in rural areas. It is also expected to address the issue of securing locations for base stations and lowers the impact of base station equipment on the landscape.

Through the trials, TEPCO PG, KDDI, SoftBank and Rakuten Mobile Network aim to reduce the infrastructure construction costs and contribute to the smooth nationwide introduction of 5G.

5G Architecture Options for Deployments?

I have blogged earlier about the multiple 5G Architecture options that are available (see Deutsche Telekom's presentation & 3G4G video). So I have been wondering what options will be deployed in real networks and when.

The 3GPP webinar highlighted that Option-3 would be the initial focus, followed by Option 2.

Last year AT&T had proposed the following 4 approaches as in the picture above. Recall that Option 1 is the current LTE radio connected to EPC.

ZTE favours Deployment option 2 as can be seen in the slide above

Huawei is favoring Option 3, followed by Option 7 or 2 (& 5)

Going back to the original KDDI presentation, they prefer Option 3, followed by Option 7.

If you are an operator, vendor, analyst, researcher, or anyone with an opinion, what options do you prefer?

KDDI Vision on FMBC (Fixed Mobile Broadband Convergence)

The following is from KDDI Annual report which is available to download here.


FMC (Fixed and Mobile Convergence) enables a variety of services and contents anywhere, any time, regardless of different communication methods and access means, be it fixed or mobile. KDDI’s next-generation infrastructure concept, “Ultra 3G,” takes this convergence one step further, to FMBC (Fixed Mobile and Broadcast Convergence). This is an area where only KDDI, which has various access lines, can pursue potentials.

The following is an article and half from the same report on FMBC:
