ClassIn online class, a one-to-many live interactive teaching platform created by Yiou Education, allows you to take classes with hotspots, because hotspots are mobile phone networks, so you can take classes with hotspots.

Mobile phone hotspot, also known as personal hotspot, can also be called WIFI hotspot, which is the function of sharing data traffic in smart phones. Turn on personal hotspot when data traffic is turned on, and the mobile phone will become a mobile wireless router, which can provide wireless data traffic for tablets and laptops. When we work outdoors and there is no wireless data nearby, we can provide wireless data in this way to solve the problem of outdoor work.
