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:

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!
