ATIS Webinar on '5G Standards Developments in 3GPP Release 16 and Beyond'

3GPP Organizational Partner, ATIS (Alliance for Telecommunications Industry Solutions), recently delivered a webinar (video & slides below) titled "5G Standards Developments in 3GPP Release 16 and Beyond". 

3GPP News details:

An expert panel brings you up-to-speed on the current state of 5G standardization. The webinar delivers a broad overview of 3GPP's work and introduces some of the key technology elements. It is suitable for people in technical roles and technical executives who want to understand the current state of 5G standardization.

In Release 16, 3GPP delivered important updates to 5G specifications to broaden their range of commercial applications and improve the efficiency of networks. 3GPP is now further enhancing 5G in Release 17 and starting to plan Release 18. This webinar provides an up-to-date view of the completed 3GPP Release 16 work with a particular focus on how the work is expanding capabilities of 5G and enhancing the technical performance of the mobile system. It also looks ahead to future 3GPP deliverables and their use cases.

What about 5G Network Architecture Option 4 (a.k.a. NE-DC) ?

You heard the news about Standalone (SA) 5G network(s)? T-Mobile USA announced this week that "T-Mobile is the first operator in the world to launch a commercial nationwide standalone 5G network". Nationwide is the key word here. Back in February, the Saudi operator STC announced that "stc - Kuwait first to launch 5G E2E SA network in MENA". We will see a lot more announcements about SA 5G this year.


I blogged in detail about the 5G Network Architecture options in this post earlier here. There we looked at the different options in details and typical migration path between the options. Whenever any operator / vendor talks about SA 5G today, they are talking about Option 2. That was back in 2018. Since then, many of the options have lost momentum.

As we all know, the current 5G networks are Non-Standalone or NSA. They are also known as Option 3 or EN-DC. The next evolution is Standalone of SA deployment. It is also known as Option 2. Right now, not many operators or vendors are talking about other options.



While some of the operators have toned down asking for Option 7 (NGEN-DC) & 4 (NE-DC) support, others haven't. Deutsche Telekom is one such operator.


In a webinar on the topic 'The Journey to Standalone 5G' back in March (available on demand here - for DT part, jump to 39 minutes point), Peter Stevens, Principal Engineer, Mobile Access, Deutsche Telekom UK discussed why DT views Option 4 as important for them. In fact if you look at the picture above, you see that they even refer to Option 4 as SA.


One of the motivations from RAN point of view is that because many UEs are not accepting low-low LTE-NR band combinations. So if an operator decided to go with nationwide SA, they have to make the cell sizes smaller than they have to be. This can create coverage gaps with 5G SA. Of course many of the newer features work far better with 5G core (5GC) so option 4 will provide speed benefits of Option 3 NSA without the limitations of 4G EPC.


Standalone without Option 4 can reduce data rates as you can see in the picture above and explained in another of our posts here.


Finally, this last picture summaries the alternatives to Option 4, Dynamic Spectrum Sharing (DSS) or fallback to NSA when 5GC services are not needed. As the slide says, neither of these options is considered a good mainstream alternative to Option 4.

Let me know your thoughts about this in the comments below.

5G Remote Surgery and Telehealth Solutions


One of the most controversial 5G use cases is the remote surgery. In this post I want to quickly look at the history and what is possible. Before I go to that, here is a short summary video that I am embedding upfront.



As far as I can recall, Ericsson was the first vendor that started talking about remote surgery. This is a tweet from back in 2017.


Huawei didn't want to be far behind so they did one at MWC Shanghai in 2018. Their tweet with video is embedded below.


In January 2019, South China Morning Post (SCMP) showed a video of a remote surgery on an animal. While the video and the article didn't provide many details, I am assuming this was done by Huawei as detailed here. The video of the surgery below.



This was followed by Mobile World Congress 2019 demo where a doctor used 5G to direct surgery live from a stage at MWC to Hospital Clinic Barcelona over 3 miles away. The team of doctors was removing a cancerous tumor from a patient's colon. This video from that is embedded below.



Vodafone New Zealand had a silly remote surgery of a dog video but looks like they have removed it.  Nothing can beat this Telecom Italia ad embedded below.



There are some realistic use cases. One of them being that with 5G the number of cables / wires in a hospital can be reduced saving on the disinfection.
NTT Docomo showcased 5G Mobile SCOT (Smart Cyber Operating Theater) which is an Innovative solution to enable advanced medical treatment in diverse environments. You can read more details here.

There are lots of other things going on. Here is a short list:
  • April 2020: Because of Coronavirus COVID-19, NT Times has an article on Telemedicine Arrives in the U.K.: ‘10 Years of Change in One Week’ - even though this does not involve 5G, it just shows that we are moving in that direction.
  • February 2020: 5G-aided remote CT scans used to diagnose COVID-19 patients in China (link)
  • February 2020: Verizon teamed with Emory Healthcare to test new 5G use cases for the medical industry at the latter’s Innovation Hub in Atlanta, in a bid to discover how the technology can be used to improve patient care. The collaboration will explore applications including connected ambulances; remote physical therapy; medical imaging; and use of AR and VR for training. (link)
  • February 2020: Vodafone 5G Healthcare – Conference & Experience Day (link)
  • November 2019: TIM enables first live remote-surgery consultation using 5G immersive reality (link)
  • October 2019: Along with a hospital in Malaga, Telef├│nica has presented what it claims is the first expert assistance system for medical interventions that runs on 5G. (link and video)
  • September 2019: Mobile Future Forward 2019 - World's First Remote VR Surgery Demo conducted on Sept 4th, 2019 in Seattle by Chetan Sharma, James Youngquist, Evie Powell, Nissim Hadar, David Colmenares, and Gabe Jones. (link)

Finally, a nice video on Benefits of 5G for Healthcare Technology by T-Mobile

Mobile Voice Communications is neither Dying, nor Dead!

If you have been following the mobile industry for a long time, you could be forgiven for thinking that voice communications is dead. This 2013 article for example talks about the impending death of voice and this 2018 article talks about how smartphones have killed the art of conversation. These are just examples and I have read many similar articles in the last 5-10 years.

The thing is that a lot of unnecessary calls became SMS and messages once the price of SMS and data went down. Similarly, voice ceased to be a differentiator in many markets so they started offering unlimited voice and/or SMS locally. This does not necessarily solve my requirements for international calling so I moved on to Viber, WeChat and WhatsApp.

The annual TeleGeography Report and Database update (just released) estimates that international over-the-top (OTT) voice traffic reached 1 trillion minutes in 2019, compared to just 432 billion minutes of international carrier traffic.

Anyway, with the lockdown in many countries because of coronavirus COVID-19, people have re-discovered the use of voice communications again. While I prefer having meetings on the internet, sometimes it's just simpler to call using your phone. A friend discovered that while she has some 40 GB data allowance that was generally more than enough, working from home means that she is having to use her device as a hotspot that is using up all her data. Switching from OTT calling to unlimited voice calling in her package means that she doesn't have to worry about voice calls eating her data package.

She is not alone. Operators all over are reporting the rise in voice communications:

  • 27 Mar 2020 - O2 UK reported, "Since March 16th we have seen approximately 57% more voice traffic at the busiest point of the day. Typically voice traffic increases 5% year on year, and in a week we have experienced an increase of voice traffic comparable to nine years of regular demand." (link)
  • 26 Mar 2020 - Official numbers reported by CTIA from Verizon, AT&T, T-Mobile, Sprint and U.S. Cellular stated that mobile voice traffic was up 24.3% while mobile data traffic was up 9.2% (see photo above - link)
  • 24 Mar 2020 - Telenor Norwar tweeted, "Traffic has increased sharply since the coronary smith was seriously registered in this country. 50% increase in mobile voice, 25% increase in mobile data and 30-40% increase in fixed broadband"
  • 24 Mar 2020 - T-Mobile USA released some interesting stats including gaming, etc. With regards to voice, their announcement said, "People are talking and texting more. Messaging is up dramatically, with a 26% increase in SMS (texting) and a 77% increase in MMS (pictures, multi-party texts, etc.). And, the amount of time people spend on calls has increased 17% nationwide." (link)
  • 20 Mar 2020 - Telia in Denmark reported, "Thursday, March 12, the volume of speech in the network thus increased by 24% compared to the day before. Over the weekend 50% more was spoken - obviously due to a need to gain status on family and friends in the new situation. In the past working week, about 60% more has been spoken on the phone than on a normal week in March." (translated from original)
Is voice important for an operator? Probably not very much in the developed markets where users pay a good amount for data packages. In developing countries, voice is still a good source of revenue. At the TIP summit last year, Malaysian telecom giant Axiata said that ""every gigabyte costs about $1.40 to manufacture...generates only 80 cents in revenue...The 2G voice business currently funds any losses". This is not a long term sustainable model for these operators.


Funnily I just remembered that in a survey of over 1000 people in the USA regarding what they want from 5G, the third most important thing was "clearer voice quality". If you want to understand how voice quality is measured that see this tweet below


We may keep on seeing a boom in voice traffic as more lockdowns occur and they are even stricter. We will have to wait and see of this habit of talking sticks or it's just for this unusual situation.

Some interesting April Fools' Day 2019 Technology Jokes


This year April Fools' Day wasn't as fun as the last one, even though it was on Monday. Many tech companies that make effort didn't make one this year. In fact Microsoft went even further and banned any public facing April Fools' pranks. Anyway, here are some of the jokes that I found interesting.

Parallel Wireless 7G Vision
This one was important for me as it features me (Yay!) and also enhanced my video editing skills. Grateful to CW (Cambridge Wireless) for being part of it too.

Video is slightly long but funny hopefully



In short, the focus for the next few years will be do design a 7G logo that can explain the vision and connect with people. Did I mention 7GPPPPP?


Google Sssnakes on a map
Google temporarily added a version of the classic game Snakes into its Google Maps app for April Fools’ Day this year.

The company says that the game is rolling out now to iOS and Android users globally today, and that it’ll remain on the app for the rest of the week. It also launched a standalone site to play the game if you don’t have the app.

Jabra Ear bud(dy)


World’s first shared headphone - engineered for shared music moments. The website says:

The headphones come with an ultra-light headband that extends seamlessly to accommodate the perfect fit for every pair of buddies, so you’ll never have to enjoy another music moment alone. The Jabra Earbud(dy)™ comes with a unique Buddy mode that promises a shared music experience that is tailored to suit each person’s preferences. Fans of voice command will be thrilled to know that with just one touch, the Jabra Earbud(dy)™ can connect to dual voice assistant.


T-Mobile Phone BoothE

T-Mobile USA and their CEO John Legere never disappoints. They always come up with something interesting. Here is a video of the prank


From MacRumours:

T-Mobile is again fighting one of the so-called pain points of the wireless industry with the launch of the Phone BoothE, a completely sound-proof and high-tech phone booth that lets T-Mobile customers escape from noisy areas to make their phone calls. Inside the Phone BoothE you can charge your devices, connect to a smart screen called "Magenta Pages" to mirror your smartphone display, and adjust the lighting to take great selfies.

In regards to the name, T-Mobile is taking a shot at AT&T's misleading 5GE label: "The Phone BoothE is an evolution towards the new world of mobility. Like many in the tech and wireless industry today, we decided that by adding an "E" to the name, you would know it's a real technology evolution." 

Although this is an April Fools' Day joke, T-Mobile has actually built the Phone BoothE and deployed them in select locations around New York City, Seattle, and Washington, DC, where anyone will be able to use them. The company on Monday also revealed the T-Mobile Phone BoothE Mobile EditionE, which is more in line with a straightforward April Fools' Day hoax, as it's "literally a magenta cardboard box with a hole in it." 

While the actual site disappeared after April 1, the archived version can be seen here.

X-Ray vision Nokia 9 PureView

The Nokia 9 PureView has plenty of cameras on its back, but did you know that the black sensor isn’t a 3D ToF camera but rather an X-Ray sensor? Can be unlocked with the new Nokia X-Ray app in Play Store


"Digi-U" from Ericsson Digital


Parallel Wireless Adds AMPS (1G) Capabilities to Their Unified ALL G Architecture


From the press release:

Worlds First Fully Virtualized AMPS (vAMPS) to enable Modernization and Cost Savings

Parallel Wireless vAMPS is compatible with: Total Access Communications Systems (TACS) in the U.K.; Nordic Mobile Telephone (NMT) System in Scandinavia; C450 in Germany; and NTT System in Japan, among others, and will allow global operators to modernize their 1G infrastructure. The 1G vAMPS solution is also software upgradable to vD-AMPS, for operators who wish to follow that path.


Truphone foldable SIM (F-SIM) for Foldable Smartphones

F-SIM – the foldable SIM – designed especially for the new foldable smartphones and tablets demonstrated at this February’s MWC Barcelona, including Huawei’s Mate X and Samsung’s Galaxy Fold.

Widely tipped as the next generation in SIM technology, the foldable SIM works on minute hinges that allow it to fold smaller than any previous SIM form factor. Made specifically for foldable phones and other devices, Truphone’s latest innovation fulfils on its broader brand promise to engineer better connections between things, people and business—anywhere in the world.

The F-SIM comes in ‘steel grey’ and, for only £5 more, ‘hot pink’. Pricing structures vary depending on data, storage, roaming charges and device model.

Minimum Bandwidth Requirement for 5G Non-Standalone (NSA) Deployment

I was attending the IEEE 5G World Forum live-stream, courtesy of IEEE Tv and happen to hear Egil Gronstad, Senior Director of Technology Development and Strategy at T-Mobile USA. He said that they will be building a nationwide 5G network that will initially be based on 600 MHz band.


During the Q&A, Egil mentioned that because of the way the USA has different markets, on average they have 31 MHz of 600 MHz (Band 71). The minimum is 20 MHz and the maximum is 50 MHz.

So I started wondering how would they launch 4G & 5G in the same band for nationwide coverage? They have a good video on their 5G vision but that is of course probably going to come few years down the line.

In simple terms, they will first deploy what is known as Option 3 or EN-DC. If you want a quick refresher on different options, you may want to jump to my tutorial on this topic at 3G4G here.

The Master Node (recall dual connectivity for LTE, Release-12. See here) is an eNodeB. As with any LTE node, it can take bandwidths from 1.4 MHz to 20 MHz. So the minimum bandwidth for LTE node is 1.4 MHz.

The Secondary Node is a gNodeB. Looking at 3GPP TS 38.101-1, Table 5.3.5-1 Channel bandwidths for each NR band, I can see that for band 71


NR band / SCS / UE Channel bandwidth
NR Band
SCS
kHz
5 MHz
101,2 MHz
152 MHz
202 MHz
252 MHz
30 MHz
40 MHz
50 MHz
60 MHz
80 MHz
90 MHz
100 MHz
n71
15
Yes
Yes
Yes
Yes








30

Yes
Yes
Yes








60













The minimum bandwidth is 5MHz. Of course this is paired spectrum for FDD band but the point I am making here is that you need just 6.4 MHz minimum to be able to support the Non-Standalone 5G option.

I am sure you can guess that the speeds will not really be 5G speeds with this amount of bandwidth but I am looking forward to all these kind of complaints in the initial phase of 5G network rollout.

I dont know what bandwidths T-Mobile will be using but we will see at least 10MHz of NR in case where the total spectrum is 20 MHz and 20 MHz of NR where the total spectrum is 50 MHz.

If you look at the earlier requirements list, the number being thrown about for bandwidth was 100 MHz for below 6 GHz and up to 1 GHz bandwidth for spectrum above 6 GHz. Don't think there was a hard and fast requirement though.

Happy to hear your thoughts.

Gigabit LTE?


Last year Qualcomm announced the X16 LTE modem that was capable of up to 1Gbps, category 16 in DL and Cat 13 (150 Mbps) in UL. See my last post on UE categories here.


Early January, it announced Snapdragon 835 at CES that looks impressive. Android central says "On the connectivity side of things, there's the Snapdragon X16 LTE modem, which enables Category 16 LTE download speeds that go up to one gigabit per second. For uploads, there's a Category 13 modem that lets you upload at 150MB/sec. For Wi-Fi, Qualcomm is offering an integrated 2x2 802.11ac Wave-2 solution along with an 802.11ad multi-gigabit Wi-Fi module that tops out at 4.6Gb/sec. The 835 will consume up to 60% less power while on Wi-Fi."

Technology purists would know that LTE, which is widely referred to as 4G, was in fact pre-4G or as some preferred to call it, 3.9G. New UE categories were introduced in Rel-10 to make LTE into LTE-Advanced with top speeds of 3Gbps. This way, the ITU requirements for a technology to be considered 4G (IMT-Advanced) was satisfied.


LTE-A was already Gigabit capable in theory but in practice we had been seeing peak speeds of up to 600Mbps until recently. With this off my chest, lets look at what announcements are being made. Before that, you may want to revisit what 4.5G or LTE-Advanced Pro is here.

  • Qualcomm, Telstra, Ericsson and NETGEAR Announce World’s First Gigabit Class LTE Mobile Device and Gigabit-Ready Network. Gigabit Class LTE download speeds are achieved through a combination of 3x carrier aggregation, 4x4 MIMO on two aggregated carriers plus 2x2 MIMO on the third carrier, and 256-QAM higher order modulation. 
  • TIM in Italy is the first in Europe to launch 4.5G up to 500 Mbps in Rome, Palermo and Sanremo
  • Telenet in partnership with ZTE have achieved a download speed of 1.3 Gbps during a demonstration of the ZTE 4.5G new technology. That's four times faster than 4G's maximum download speed. Telenet is the first in Europe to reach this speed in real-life circumstances. 4.5G ZTE technology uses 4x4 MIMO beaming, 3-carrier aggregation, and a QAM 256 modulation.
  • AT&T said, "The continued deployment of our 4G LTE-Advanced network remains essential to laying the foundation for our evolution to 5G. In fact, we expect to begin reaching peak theoretical speeds of up to 1 Gbps at some cell sites in 2017. We will continue to densify our wireless network this year through the deployment of small cells and the use of technologies like carrier aggregation, which increases peak data speeds. We’re currently deploying three-way carrier aggregation in select areas, and plan to introduce four-way carrier aggregation as well as LTE-License Assisted Access (LAA) this year."
  • T-Mobile USA nearly reached a Gigabit and here is what they say, "we reached nearly 1 Gbps (979 Mbps) on our LTE network in our lab thanks to a combination of three carrier aggregation, 4x4 MIMO and 256 QAM (and an un-released handset)."
  • The other US operator Sprint expects to unveil some of its work with 256-QAM and massive MIMO on Sprint’s licensed spectrum that pushes the 1 gbps speed boundary. It’s unclear whether this will include an actual deployment of the technology

So we are going to see a lot of higher speed LTE this year and yes we can call it Gigabit LTE but lets not forget that the criteria for a technology to be real '4G' was that it should be able to do 1Gbps in both DL and UL. Sadly, the UL part is still not going Gigabit anytime soon.

Some interesting April Fools' Day 2016 Technology Jokes

When I posted April Fools' jokes on the blog last couple of years (see 2014 & 2015) , they seem to be very popular so I thought its worth posting them this year too. If I missed any interesting ones, please add in comments.


The one I really liked best is the Samsung Internet of Trousers (IoT) featuring:

Wi-Fly: Gone are the days of unnoticed, unzipped trouser zippers upon exiting the restroom. Should your fly remain open for more than three minutes, the ZipARTIK module will send a series of notifications to your smartphone to save you from further embarrassment.

Get Up! Alert: Using pressure sensors, Samsung’s intelligent trousers detect prolonged periods of inactivity and send notifications to ‘get up off of that thing’ at least once an hour. Should you remain seated for more than three hours, devices embedded in each of the rear pockets send mild electrical shocks to provide extra motivation.

Keep-Your-Pants-On Mode: Sometimes it’s easy to get carried away with the moment. The Samsung Bio-Processor in your pants checks your bio-data including your heart rate and perspiration level. If these indicators get too high, Samsung’s trousers will send you subtle notifications as a reminder of the importance of keeping your cool.

Fridge Lock: If the tension around your waist gets too high, the embedded ARTIK chip module will send signals to your refrigerator to prevent you from overeating. The fridge door lock can then only be deactivated with consent from a designated person such as your mother or significant other.



Microsoft has an MS-DOS mobile in mind for this day. I wont be surprised if a real product like this does become popular with older generation. I personally wouldn't mind an MS-DOS app on my mobile. Here is a video:





It would have been strange if we didnt have a Robot for a joke. Domino's have introduced the Domimaker. Here's how it works:





T-Mobile USA is not shy pulling punches on its rivals with the Binge On data plan where it lets people view certain video channels without using up their data. Here is the video and more details on mashable.



Samsung ExoKinetic helps your phone self-charge

Google had quite a few pranks as always. I will ignore 'mic drop' which backfired and caused them headache.

Google Express has a new delivery mechanism, just for the April Fool's day. (There has to be one drone idea)





Google Cardboard Plastic is an interesting one too. Here is the video:


Finally, its the Google Fiber Teleportation.



Other interesting ones:
