Fast and strong Wi-Fi in the entire house
Many households need to solve problems with Wi-Fi connection quality even when they have a sufficiently fast connection. That is why we have created a super efficient modem O2 Smart Box, which will cover your entire house with a signal. Seven Wi-Fi aerials will take care of high-speed data transfers without any variations in performance. The Smart Wi-Fi function chooses the most suitable broadcasting frequency (2.4 and 5 GHz) so that you do not get disturbed by your neighbors’ signal.
Watch HD quality videos without waiting
Before you watch your favorite video on your monitor, it often needs to travel incredible distances. Servers can be as far as 1,000 kilometers away. This decreases its uploading speed and it can sometimes get jammed. That’s why we have saved majority of videos from the most viewed websites directly in our network and thus we have increased your way to them.
How to check the uploading speed and video quality
1) Play the YouTube video below. In the bottom right-hand corner click on the settings wheel icon and switch the video to HD quality (ideally 1080p).
2) Check how quickly the video uploads and if it plays without jamming.
3) Right click on the video. Choose the "Statistics for experts" icon and check the following parameters:
- Buffer Health is a very important value. It tells you how the video is uploading and how many seconds of the video you have downloaded ahead of time. The higher the value, the better. If the buffer is getting close to a zero, your video will jam.
- Connection Speed shows how quickly the video uploaded. Nevertheless, this is not the connection speed.
- Dropped Frames informs you about your connection or modem errors. The fewer there are, the better your video watching experience is.
Security and other benefits of a smart household
O2 Smart Box is not just a super efficient modem. You can connect your door or window sensors, fire detectors, smart outlets or movement detector to it. Simply install a mobile app to your phone and you will become the ruler of your smart household. What does it look like is entirely up to you. For starters we will give you a door sensor worth CZK 999 for free with your k O2 Smart Box.
