CLIENT SOFTWARE
RADIUS Client Software
Operator & Administrator Interface for the RADIUS RoIP System
The RADIUS Client for Windows is the primary operator and administrator interface for the RADIUS Radio-over-IP (RoIP) system. It provides a unified graphical user interface (GUI) for interacting with RADIUS Gateways and the RADIUS Distribution Service, enabling mission-critical radio communications across radios, computers, smartphones, and IP devices.
The RADIUS Client is designed to support both day-to-day operator functions and system administration tasks within a single, consistent application.

Designed for Mission-Critical Operations
The RADIUS Client enables administrators to configure radio resources, define channels, and assign permissions, while allowing operators to quickly learn and repeat critical communication functions under operational conditions.
User access to functions and resources is controlled through configurable profiles, ensuring each operator sees only the channels and capabilities required for their role.
RADIUS Graphical User Interface (GUI)
The RADIUS Graphical User Interface is purpose-built to present the controls and resources required for real-world mission-critical communications. The interface combines administrative configuration and live operational control within a single application.
ADMINISTRATIVE CAPABILITIES
Administrators can:
-
Create and manage users
-
Configure radio and IP resources
-
Create channels and cluster groups
-
Assign user profiles and permissions
-
Enable or restrict access based on organizational requirements
OPERATOR CAPABILITIES
Operators can:
-
Monitor assigned channels
-
Transmit to individual resources, channels, or patches
-
Create and manage crossbanded groups
-
View channel membership and system status in real time
Channel-Based Operation
The Channels and Dashboard modules provide a simplified, intuitive operator experience. Operators see only the channels assigned to their user profile, reducing complexity and minimizing the potential for error.

CHANNEL FEATURES
• Push-to-Talk (PTT) per channel
• Select / unselect audio control
• Mixed audio for simultaneous audio streaming
• Left / right audio panning
• Relay-closure compatible push-button PTT
• Assignment of specific channels to specific users
Advanced Crossbanding & Command Functions
The RADIUS Client Command interface provides advanced system control for experienced operators and supervisors.

OPERATOR CAPABILITIES
Operators can:
• Create crossbanded cluster groups
• Build channels by dragging and dropping radio assets
• PTT directly to groups and channels
• Move and organize cluster groups
• Save and load pre-configured groups and channels
• Enable, disable, or rename groups and channels
This supports both planned and dynamic operational scenarios.
Simplified Group Communications
The RADIUS Client builds upon the SyTech RIOS graphical user interface and introduces RIOS Cluster Groups for simplified crossbanding and interoperability.
Cluster Groups may include:
• Physical radios
• Computers and workstations
• Smartphones and mobile clients
• Crew stations and VoIP devices
This enables seamless interoperability among all connected devices within a channel or group.
VoIP & IP Device Integration
The RADIUS Client supports VoIP and IP-based devices as virtual radios within the system. Devices may be configured for multicast or unicast audio and appear as radio resources in the operator interface.
VOIP CAPABILITIES
• Multicast audio support
• Unicast audio support
• Bridging among WAVE, Vocality, and RIOS interfaces
• Configurable Time-To-Live (TTL) settings
Virtual radios may be patched with physical radios for two-way RF/IP communications.
Remote Radio Control
The RADIUS Client supports remote radio control for supported platforms, extending operator control beyond audio transport to radio configuration and management.

REMOTE CONTROL CAPABILITIES
• Remote steering of Motorola O5 control head radios (APX & XTL)
• On-screen access to zone, channel, reset, and programmable buttons
• Motorola accessory interface support via SyTech RCU cable (CAB-00209B)
• Remote control of Harris 117G and 160 radios using on-screen RADIUS KDU
Recording & Playback
RADIUS supports optional recording and playback workflows for operational review and controlled playback scenarios.
