Wi-Fi assistantor WiFi Assist, is a function implemented by the company Apple Lossless Audio CODEC (ALAC), for its iPhone and iPads, giving us the opportunity to use the fastest internet connections in our terminals.
I have already explained how the Wi-Fi Assistance system works iOS 9, he automatically deactivating it Wi-Fi when the signal has a low value and automatically activating a data connection to give us the opportunity to surf the Internet in much better conditions.
Practically, Wi-Fi assistant it will automatically switch from Wi-Fi to 3G or 4G when you surf the Internet if your Wi-Fi connection is no longer stable or the Internet browsing speed is reduced, all without warning you at one point or another of this change.
I noticed this functionality a WiFi Assist today while surfing the internet at a considerable distance from my Wi-Fi HotSpot and the signal was not as strong, but instead of maintaining the Wi-Fi connection, iOS 9 it switched to 4G immediately, although the Wi-Fi signal fluctuates between 2 and 3 dashes.
Wi-Fi assistance and how you could stay without a lot of money
The change was made in the summer without any prior warning and I only noticed it when I raised my eyes to the upper part of an internet page and the 4G indicator for the GSM connection of my terminal came to my attention.
Normally for surfing the Internet this shouldn't be a very big problem, but in the case of streaming video clips via YouTube, or viewing online TV stations, things could become extremely complicated for many.
Why am I saying this? Well, because at some point the internet connection will switch from Wi-Fi to 3G or 4G without you knowing, especially if you view something in fullscreen mode and additional data traffic will be generated in the subscription, or it will be consumed the existing one.
In this idea, I recommend you to use Wi-Fi Assist, Wi-Fi Assistance, only if you are 100% sure that the eventual generation of a large Internet traffic is not a problem.
