Google Chromecast: Can You Connect Directly to Phone without Router? Casting YT, Photos

Hi.
I do not know in what department to write, whether telephones or televisions or what ... ?
Help the old man I saw something like "Google Chromecast" on the Internet and I would like to buy something to cast a picture (e.g. YT or photos) on the TV from my phone. Everywhere in the configuration shown they say that you choose your network name and password. I would like to connect it in a place where I do not have internet? I mean, I don't have a router there. Is it possible to connect "Chromecast" directly to the phone?

of course it is possible! Too much to describe so I recommend you go to ytube there a little faster it will be explained.
"How to use ChromeCast without WiFi"
"HOW TO CONNECT CHROMECAST USING ONLY ONE SMARTPHONE"
"How to Setup Chromecast With TV Using Your Phone" etc etc. you will find many examples!

best regards

I do not know if I understood English correctly but you need to do a mobile hot spot or a router from your phone. The problem is that I would like to connect via chromecast to the TV with a tablet that does not have 3G and it is not possible to make a mobile router. That is why I asked if it is possible to connect as if ad hoc directly to the chromecast with the wifi module itself without internet.

Hello. I hook up to the question, the problem is that I want to connect to the chromecast device without using any router, using only one phone, the data transmission of this phone is to be used as the internet source. I have no idea how this system can work without wifi or thehering from a second device, so I am asking for a lopological explanation of exactly how to do it.
