Enabling unlimited IP content delivery

5G Broadcast meets Broadband

Nakolos develops products and solutions for content providers and broadcast network operators to utilize the combination of 5G Broadcast and Broadband on Android mobile devices.

The core technology consists of a lightweight middleware which enables Android apps to benefit from the advantages from 5G Broadcast which is seamlessly integrated with the existing broadband connection, e.g. Wifi or 5G.

A cloud-based control system monitors the current load of content in specific areas and based on the previously set thresholds automatically provisons the 5G Broadcast reception.

Use Cases

Seamless Switching
Seamless switching between 5G Broadcast and broadband.

Uninterrupted content streaming anytime, anywhere.

More info …

The seamless switching functionality of the Nakolos Middleware guarantees an uninterrupted viewing experience anytime, anywhere.

If the user leaves the broadband reception and 5G Broadcast is available in that area the Nakolos middleware will seamlessly switch the stream to 5G Broadcast without the user noticing and vice versa.
The Nakolos middleware allows content providers an easy integration of 5G Broadcast into their OTT app without a high implementation effort.

Broadcast on Demand
Reduction of content delivery costs by using 5G Broadcast.

5G Broadcast provisioning based on consumption reports and thresholds.

More info …

Based on consumption reports delivered by the middleware to the Nakolos backend, content providers can reduce their content delivery costs by using free 5G Broadcast capacities of Broadcast Network Operators on demand. The content provider easily can setup a threshold when its more cost efficient to use 5G Broadcast than streaming via CDN.
For example Nakolos monitors the content demand in a specific area, if the threshold is reached it enables 5G Broadcast in that area. Most of the users will automatically switch from CDN to 5G Broadcast reception (using the Nakolos seamless switching functionality).

Low Latency for live events
Seamless switching with low latency for your live event.

Latencies even below one second enable an immersive experience for your audience.

More info …

With the support of low latency for live events the Nakolos middleware provides an elegant solution to enable high resolution low latency streams within a crowded audience e.g., during a Formula 1 race, soccer or at concerts and festivals.
With the use of a local Nakolos 5G Broadcast distribution setup, the live stream experience of the consumers will be improved with latency below one second.


Dynamic Provisioning

Based on the available data, Nakolos can decide whether and which services should be dynamically provisioned.

Easy Integration

Nakolos consists of a lightweight, single-line integrable software solution for your mobile app and a cloud-based backend.

Switching Logic

Nakolos is able to switch seamlessly between 5G BC and CDN when exiting/entering a 5G BC environment or by instruction from the controller.

Streaming Protocols

Nakolos supports the latest streaming protocols such as HLS, DASH, CMAF and more.

Getting started

Test environment
