Broadcast Radio Head for Direct‑to‑Mobile (D2M) Broadcast

Reduced Congestion and improved Spectrum efficiency for Content Delivery
Broadcast Radio Head (BRH) is a next generation Digital Terrestrial Transmission (DTT) solution designed to deliver Direct to Mobile (D2M) broadcast content with high efficiency and uniform coverage. BRH enables scalable and spectrum efficient broadcast delivery for mobile, automotive, and portable devices.

BRH is deployed using a Low Power Low Tower (LPLT) or cellularized broadcast architecture, creating a uniform field strength across coverage areas. LPLT based BRH deployments can also supplement conventional High Power High Tower (HPHT) broadcast networks when deployed in Single Frequency Network (SFN) mode, enabling flexible hybrid broadcast topologies.

Designed for ubiquitous coverage, the Broadcast Radio Head delivers high quality broadcast signals to mobile devices without relying on cellular broadband or Wi Fi connectivity. BRH helps reduce congestion on mobile networks by offloading high viewership content from unicast cellular delivery to broadcast networks.

It supports modern broadcast network requirements, including SFN and MFN deployment topologies, precise GPS based location and time synchronization, and STL TP support for ATSC 3.0. Centralized Element Management System (EMS) support enables remote monitoring and software upgrades, ensuring operational simplicity and future ready deployments.

Open-Integrated DU/CU:

Our DU/CU solution is based on our unique Software Defined Radio (SDR) architecture which provides customers an open and dynamic vRAN platform that not only provides functional flexibility but also optimizes the TCO. This platform is the result of deep expertise in designing DSP based RAN platform. The open fronthaul interface, Control & Management Software is designed as per ORAN standard providing plug and play interoperability with 3rd party Distributed Units (DUs).

5G RU:

This is an ORAN based 5G NR Radio Unit. The solution includes support for various bands specially the low and mid bands like Band 71, 29 and 40. It can be customized for other bands as well.
The solution incorporates a unique front haul compression technique to reduce op-ex for operators
