SOLiD BARS™
DAS

System Overview

Preliminary Revision P0.1

SOLiD BARS™ is an advanced in-building solution that enhances cellular signals and provides reliable multi-operator coverage for up to four mobile operators. It is designed to comply with applicable regional regulatory requirements, potentially eliminating the need for retransmission agreements, and supports up to forty (40) remote units from a single head-end using up to four (4) hubs. The system includes an Echo Cancellation System (ECS) for stable performance and is managed through the SOLiD BARS™ EMS Portal, with on-site access via the LocalGUI.

Low Total Cost

SOLiD BARS is designed to meet licence‑exempt regulatory requirements across global markets, ensuring compliance while maintaining high performance, reliability, and ease of deployment.

Ethernet cabling helps reduce installation complexity and commissioning time.

The head-end and hubs each support up to eight (8) remote units, reducing the need for additional head-end and donor equipment.

**Easy Setup (Installation & Commissioning)**

A single Ethernet cable per remote unit helps reduce cabling requirements.
Power-over-Ethernet (PoE) supports flexible remote unit placement.
Automatic commissioning helps reduce configuration errors and on-site visits.
Echo Cancellation System (ECS) helps prevent signal oscillation.
Donor antenna positioning can be verified via the LocalGUI (where applicable).
Uplink inactive (sleep) mode supports compliance with applicable regulatory requirements.

**Multi-MNOs & Multi-Bands**

Supports up to four mobile operators in a single system.
Supports multiple frequency bands per mobile operator to accommodate diverse deployment environments.
Each mobile operator is processed independently to improve isolation and overall system performance.

Web-based System

Provides a web-based interface for simplified commissioning.
The SOLiD BARS™ EMS Portal enables continuous monitoring and system optimisation.

Advanced Network Management

Supports SNMP v2c/v3 for monitoring and alarm reporting.

Enables integration with external network management systems (NMS).

Head-end Unit (HE)

Head-end Unit (HE)

The BARS head-end unit (HE) is the core of the system. It receives and digitises signals from up to four mobile operators, then delivers data and power to remote units (RUs) via

dedicated Ethernet cables. The HE extends its coverage by supporting up to 40 RUs simultaneously.

Hub Unit

The HUB unit serves as a distribution component within the BARS system. It transmits data from the HE up to 10 km using an SFP module and connects to up to eight remote units (RUs).

Remote Unit (RU)

Remote Unit (RU)

The BARS Remote Unit (RU) extends the limited coverage of the head-end unit (HE). It receives cellular signals directly from the HE or through a HUB, converts them into RF ( radio frequency) signals, amplifies them, and transmits them through its RF port.

Commercial Properties

Is your Network keeping up with demand?

Fibre optic networks connecting buildings, which once promised endless room for growth, are becoming exhausted by the flood of new wireless data services and cellular traffic from Distributed Antenna System (DAS) deployments. Solving fibre exhaustion by pulling additional fibre lines or leasing dark fibre is expensive and delays ROI.
