With Google's Chromecast media content such as movies, photos, apps, smartphone display etc. can be perfectly streamed on the television at home. The Google Chromecast is plugged into the HDMI port of the TV and then integrated via WLAN in your home network.
Now you may ask:
Can I even without a Wi-Fi network operate the Google Chromecast at home?
The answer is: Yes and no
Because the Google Chromecast requires an Internet connection via Wi-Fi for the first time setup. Here the latest firmware will be downloaded and installed on the Chromecast. Then the Chromecast can also be operated without a Wi-Fi network. Therefore the so-called guest mode is integrated, which enables the possibility to stream content from a smartphone to your TV.
