LanSchool Air System Requirements
Instructor Devices
The LanSchool Air instructor interface is web-based and only requires a supported web browser. We recommend instructors and admins use the latest version of one of the following browsers:
- Google Chrome
- Mozilla Firefox
- Microsoft Edge (New, Chromium-based version)
- Safari ( on macOS only)
Student Devices
In order to monitor and manage student devices, LanSchool Air requires that an agent and browser extension be installed on student devices. The following device operating systems are supported:
- Chromebooks running ChromeOS 71 or newer
- Windows devices running Windows 7, 8.1, or 10
- Mac devices running 10.13 (High Sierra), 10.14 (Mojave), or 10.15 (Catalina)
For complete deployment instructions, see the LanSchool Air Setup Guide.
Language Support
LanSchool Air instructors and admins can select their preferred language by selecting the 
icon in the toolbar. Selecting a new language will immediately update the language settings for that user. Any future email notification such as account activation or password reset requests will be set to use this preferred language as well. The agent installed on student devices will use the language of the operating system.
LanSchool Air includes translations for the following languages:

Network and Firewall Settings
Bandwidth Recommendations
When monitoring student screens with LanSchool Air, screenshots are sent to the teacher every few seconds. Depending on the size of the thumbnails the teacher is requesting, peak bandwidth usage could reach between 16-32 kbps per student device.
For the best experience, we recommend a teacher have at least a 0.5 Mbps internet connection speed for viewing a class of 30 student devices. If thumbnail images seem to load too slowly, consider switching to Class List View.
Firewall / Proxy Exceptions
In order for students and instructors to reliably access LanSchool Services, ensure that the following websites are allowed through your network firewall, security appliance, proxy, or content filter. All traffic is sent over TCP ports 80 or 443. All communication is secured using TLS.
