PROTOTYPES

INFORMATION

5G-MAG is gathering together developers working on open source code projects with an application to the media industry. High-quality open source platforms permit to advance on assessing 5G technologies on the laboratory and in the best case on the field before COTS equipment is ready for acquisition and use.

An informal group has been established to foster collaboration among developers of such solutions.

Open Broadcast Edge Cache Appliance - OBECA

OBECA is an open-source platform to:

  • receive 5G Broadcast (5G BC) in dedicated mode, i.e., using 100 % downlink capacity (also known as EnTV/FeMBMS in 3GPP Rel.14 and LTE-based 5G Terrestrial Broadcast in 3GPP Rel.16) with 3, 5, 6*, 7*, 8* and 10 MHz channel bandwidth

  • combine 5G Broadcast with mobile broadband, process and cache for common applications of broadcasters

  • develop interactive applications and proof-of-concepts for hybrid distribution scenarios for broadcasters

 

The OBECA platform development was initiated by the Austrian Broadcasting Services (ORS Group) in mid-2020 and first released in April 2021. Developments continue and broadcasters, app developers and other 5G broadcast enthusiasts are invited to contribute to the platform.

OBECA is built as a modular platform to later migrate modules to mobile devices in the growing 5G ecosystem.

General information about the OBECA project and other 5G Broadcast activities can be found on the homepage of the Austrian Broadcasting Services.

Technically advanced users can find all information about source code, installation, sample files, hardware requirements etc. on the Github wiki page.

In case you have any questions, need support or want to contribute to the project, please contact obeca@ors.at.

 

OPEN AIR INTERFACE

Based on OpenAirInterface, the "fembms-enb-ue" branch currently offers an implementation of the eNodeB and UE of the further evolved multimedia broadcast multicast service (FeMBMS), which in the version of the LTE eMBMS standard that offers a receive-only mode for downlink only broadcast transmissions. Specified under 3GPP Rel.14, several modifications were made to enhance the system architecture and media formats flexibility for content providers, broadcasters and mobile network operators.

Key 3GPP eMBMS radio interface enhancements, critical to enable large area single-frequency network (SFN) operation, were introduced in 3GPP TS 36.211, TS 36.212 and TS 36.213 and now included in the code.
 

What can be configured?​

  • eMBMS Mixed-cell broadcast/unicast FDD for both RFSIM (simulation) and USRP on-boarding.

  • FeMBMS Dedicated-cell broadcast for both RFSIM (simulation) and USRP on-boarding.

How to do it?

A recent Wiki provides the necessary steps for the instalation of the OAI modules (ENB, MCE, MME and UE): https://gitlab.eurecom.fr/oai/openairinterface5g/-/wikis/fembms

Docker files of the different components are also available for download.

A simple test for end-to-end video streaming is also provided so that the solution can be tested with real content.
