Offline Education Solutions That Work Without the Internet
An offline-first digital learning solution for system integrators and project companies delivering NGO, government and rural school projects. Teach anywhere — no internet, no problem. We design the solution and supply the hardware; you deliver it on the ground.
Challenges We Solve
Offline education projects fail on logistics, not lesson plans. Here is what we engineer around so you can deliver.
No internet connectivity
A local content server delivers every lesson, video and quiz over a local network — nothing depends on the cloud.
Unreliable electricity
Low-power devices plus battery backup keep classes running through outages and off-grid, solar or generator sites.
Limited on-site IT support
Pre-configured devices, MDM and remote support mean teachers can run the classroom without an IT team on site.
Difficult content distribution
Load content once onto the server; tablets sync locally, and updates ride in automatically whenever a connection appears.
Multi-school deployment
A repeatable template — mobile lab or whole-school — scales from one classroom to a district or ministry rollout.
Teacher digital readiness
A simple, unified launcher and setup guidance lower the learning curve for first-time digital teachers.
Built for Places the Internet Hasn't Reached
This solution sells one thing above all — deliverability. Real learning, in real conditions, with or without a network.
Works Fully Offline
A local content server delivers lessons over a local network — no internet connection required to teach.
Low Infrastructure
Low-power devices and battery backup. Designed to run where power and connectivity are limited.
You Control the Content
Built on Kolibri. Load your own curriculum and local-language materials. We give the platform; you keep the content.
Ready to Deploy
Built from proven hardware — tablets, charging carts, access points — so projects ship and scale fast.

How an Offline Classroom Actually Works
No internet reaches the devices. A local content server hosts everything, and tablets connect to it over a local network — fully self-contained.
(Kolibri host)
(no internet)
(class set)
(store & charge)
The content server hosts all lessons locally — no internet is needed for students to learn, stream video, or take quizzes.
When a connection is available, the server syncs new content and student progress — then works offline again.
The access point needs a PoE switch (802.3af/at), supplied by the system integrator — not in the Tralltech BOM.
Designed for low-power, limited-grid sites. Power — mains, solar or generator — is arranged on site by the integrator.

T-PWRFrequently Asked Questions
Can students really learn without any internet connection?
Yes. A local content server hosts all lessons, videos and quizzes, and tablets connect to it over a local Wi-Fi network. No internet is required for daily teaching. When a connection is occasionally available, the server syncs new content and student progress, then continues working offline.
What software runs the offline learning platform?
The solution is built on Kolibri, an open-source offline learning platform. You load your own curriculum and local-language materials onto the content server. We provide the platform and setup guidance; you keep full control of the educational content.
What equipment do I need for an offline classroom?
At minimum you need a local content server, a set of student tablets, and a wireless access point to create the local network. A charging-and-storage cart and battery backup are recommended for daily use and power resilience, and an interactive flat panel can be added as a shared front-of-class screen. The equipment checklist above shows what is required and what is optional, and we build the full BOM for your project.
How many students can one content server support?
A single content server comfortably supports a full class set connecting over the local network at the same time. For a whole school, a higher-capacity server (T-SRV-EDU-PRO) and additional access points let multiple classrooms stream content simultaneously. We size the server and network to your student numbers as part of the solution design.
Can teachers track student progress without internet?
Yes. Kolibri records each student's activity and quiz results on the local content server, so teachers can review progress entirely offline. When a connection is occasionally available, that data can sync centrally, then the system returns to working offline.
What languages and curricula does the offline platform support?
The platform is content-agnostic. You load your own curriculum, local-language lessons and approved materials onto the content server, so it can match any national curriculum or local language. We provide the platform and loading guidance; you keep full control of the educational content.
Do you sell directly to NGOs and governments, or through system integrators?
We work exclusively through system integrators and project companies delivering NGO, government and education projects. We never contact your end clients directly, and an NDA is available on request. The project, the relationship, and the margin all stay with you.
How does this solution handle sites with unreliable power?
The devices are low-power and support battery backup, so they are designed for limited-grid environments. The power source itself — mains, solar or generator — is arranged on site by the system integrator according to local conditions.
Can I start with one mobile classroom and scale up later?
Yes. The Level 1 Mobile Lab equips a single class set with a content server, tablets, charging cart and access point. You can add more access points, tablets and a higher-capacity server to grow toward a whole-school deployment.
Can you provide OEM branding on the devices?
Yes. Our own brand is the default, but OEM and ODM branding is available so you can deliver tablets and equipment under your own brand. Because we never contact your end client, the brand and the relationship stay yours.
How long does delivery take?
Lead time depends on the configuration and order size. We ship a discounted sample within about three business days and provide a documented production and dispatch schedule for the full order, so you can plan installation and your tender timeline. Freight, customs clearance and on-site installation are handled on your side as the local integrator.
Do you provide documentation we can submit in a tender?
Yes. We provide offline architecture diagrams, complete BOMs, and technical documentation ready for you to put your name on and submit to an NGO, ministry or tender.
