Finland: A country with only Unlimited Data Plans

I was listening to Elisa couple of weeks back, at 5G World Summit. One of the things that surprised me was that Elisa offered unlimited data plans but the price varied based on the maximum speeds possible. The same approach was going to continue with 5G. When 5G data speeds would improve, new packages will be added with the improved speeds.

"There's no revenue upside with unlimited mobile data", say operators with bucket plans. Funny then that the all-unlimited Finnish MNOs @ElisaOyj @teliafinland @DNA_fi all had increasing ARPU in 2018 - in contrast to almost all mature market operators solely offering buckets.

Tefficient has pointed out multiple times that even though all operators in Finland offer unlimited data plans, their ARPU has increased in 2018. This is in contrast to the other mature markets, even though they may not be offering unlimited data plans.

"Finnish operators that executed ‘unlimited everything’ strategies were the undisputed champions of the 4G era" #Rewheel https://t.co/APZXMXj7EH

Same thing was pointed out by Rewheel research that highlighted in their May 2019 report that, "Finnish operators that executed ‘unlimited everything’ strategies were the undisputed champions of the 4G era"

A mashable article pointed out that "5G will be crazy fast, but it'll be worthless without unlimited data". This is very true.

When people talk about 8K video over 5G, most of them don't realise that it would consume roughly 7-10 GB data per hour on 8K video.

Mobile operators should start thinking about how they can offer unlimited data plans, especially if they keep touting applications that are going to use loads of data. As you can see from the tweet above, a 1 hour 8K video streaming would roughly use between 7 - 10 GB of data.

Let me know your thoughts.

Case Study: LTE for real time news gathering by Sky News

Back in May, I had the pleasure of listening to a talk by Richard Pattison from Sky News where he talked about how they have managed to start replacing their Satellite trucks (which are extremely expensive to own and run) with the new solutions using LTE.

One of the advantage of LTE over 3G/HSPA+ is that the uplink is as good as the downlink which wasn't really the case in earlier generations. What this means is that you can use your phone to do a live video call and use that for broadcasting of real time information. The Sky News Tech team has some interesting tweets on this.

An example of the video quality could be seen from this clip here:

The Dejero App is an interesting one that can allow bonding of Cellular + WiFi and provide a combined data rate.

I was having a discussion yesterday on Twitter because we term this bonded cellular and WiFi as 4.5G. There are many proprietary solutions available for using them together but the standardised one is coming in standards soon.

Sky news have managed to set up new standards by having 12 feeds simultaneously broadcasting  (all based on Iphones and Ipads) during the European elections.



All this has been possible due to an amazing 4G network by EE and being able to negotiate a 500GB (0.5TB) data package.

In case you've ever wondered, this is what 500GB of mobile data looks like... #EE #4GEE pic.twitter.com/7v27RncK

Anyway, you can read the complete paper below:

Mobile Video Offload using Wi-Fi is the only solution in the coming years

A very interesting infographic from Skyfire some months back highlighted some very valid issues about Video on mobiles.

Personally, I do watch quite a bit of video on my phone and tablet but only when connected using Wi-Fi. Occasionally when I am out, if someone sends me video clip on Whatsapp or some link to watch Video on youtube, I do try and see it. Most of the time the quality is too disappointing. It could be because my operator has been rated as the worst operator in UK. Anyway, as the infographic above suggests, there needs to be some kind of an optimisation done to make sure that end users are happy. OR, the users cn offload to Wi-Fi when possible to get a better experience.

This is one of the main reasons why operators are actively considering offloading to Wi-Fi and have carrier WiFi solutions in place. The standards are actively working in the same direction. Two of my recent posts on the topic of 'roaming using ANDSF' and 'challenges with seamless cellular/Wi-Fi handover' have been quite popular.

Recently I attended a webinar on the topic of 'Video Offload'. While the webinar reinforced my beliefs about why offload should be done, it did teach me a thing or two (like when is a Hotspot called a Homespot - see here). The presentation and the Video is embedded below. Before that, I want to show the result of a poll conducted during the webinar where the people present (and I would imagine there were quite a few people) were asked about how they think MNO will approach the WiFi solution in their network. Result as follows:

Here is the presentation:

Video Offload -Six trends you NEED to understand! from Zahid Ghadialy

Here is the video of the event:

Adaptive Video Streaming: Principles, Improvements and Innovation

An Interdigital presentation from last year explains the principle of adaptive streaming very well for those who would not know how it worked.

This process of adaptation could be improved based on the quality of coverage at any particular time.

Interdigital are proposing a further enhancement of improving the adaptation further based on the User behaviour. If for example the user is far away then the quality need not be great on the device. On the other hand if the user is very close-by, the quality should be as good as it can get. They have explained it in a whitepaper for whoever is interested here.

A video showing this method is embedded below:

Data Consumed by Different Streaming Applications

Interesting table from the 4G Americas presentation about data consumption by different streaming apps. With LTE getting deployed and tablets becoming popular, I wont be surprised to see 1GB allowance consumed in couple of days. In a blog post on Verizon Wireless website earlier they had mentioned that 4GB data bucket will be minimum that is needed. In the end I think we may all stick with the trusted and reliable WiFi for thats fast and free!
