In an era in which wireless networks connect everything from factory automation to field sensors, one thing has become acutely clear — connectivity alone is insufficient. What organizations truly require is secured, verifiable, and controlled access to their private networks — and that’s exactly what Connectivity with SIM Authentication in DG505G delivers, ensuring seamless and secure network access across devices.
The onset of industrial IoT, smart utilities, and remote operations has shifted data security to the network edge — where devices intersect with the real world. This is precisely the arena where Horizon’s USB Dongle DG505G excels.
Horizon’s DG505G 5G USB Dongle, which uses SIM-based authentication, provides secure, high-speed connections to laptops, edge devices, and gateways — rendering each connection trusted and traceable.
Why SIM-Based authentication matters in modern networks
As companies move towards private LTE and 5G networks, network security has become a necessity. Conventional Wi-Fi or open cellular connectivity is just not secure enough to address the high-security requirements of such critical industries as energy, utilities, and oil & gas. Enter SIM-based authentication — the foundation of mobile identity. Every SIM is a digital key that only grants authorised users and devices access to the network.
In contrast to passwords or static settings, SIM credentials are safely stored in the chip and cannot be tampered with or copied. This hardware-based identity management provides a closed-loop communication setting, wherein every device is identified, authenticated, and encrypted prior to data exchange.
DG505G: Small form factor, Enterprise-class security
The Horizon DG505G may appear small enough to be a USB dongle, but it’s an industrial-grade CBRS modem in there, designed to power high-performance access to private LTE and 5G networks. It accomplishes this through Band 48 spectrum and SIM-based authentication to provide unbridled control over access.
Plugged directly into a computer, IoT controller, or industrial gateway, the DG505G converts it immediately into a secure, high-speed LTE/5G terminal — no setup or software agony necessary.
Key Benefits
- Plug-and-Play Installation: Simple connection to private LTE or 5G networks.
- Secure SIM-Based Connectivity: Only authorised SIMs can connect, minimising intrusion risk.
- Enterprise-Class Encryption: LTE and 5G protocols are supported with layers of added security.
- Rugged Reliability: Built to withstand industrial and field environments with dependable performance.
- Flexible Deployment: Gets along with Horizon gateways, CPEs, and private networks.
How SIM-Based authentication protects data
Security in modern networks relies on trust at every point — device, identity, and data. Horizon’s DG505G upholds this chain of trust through SIM-based authentication, which verifies each connection prior to transmitting data.
Here’s how it works in action:
1. Unique device identity:
Every SIM card plugged into the DG505G has a unique subscriber identity that is identified by the private LTE/5G core. It bars unauthorised or cloned devices from snooping in.
2. Mutual authentication:
The identity of each other is verified by the device and network when connected via the DG505G — building mutual trust prior to creating a session.
3. Encrypted transmission:
Upon authentication, everything is encrypted automatically by LTE/5G security mechanisms such as AES and IPsec, guaranteeing the confidentiality and integrity of data.
4. Automatic session renewal:
In case of loss of a session or when a device moves between the cells of a network, automatic reauthentication occurs without requiring user intervention — with a seamless yet secure connection.
These mechanisms altogether remove human misconfiguration mistakes, limit spoofing chances, and impose zero-trust network access policies.
Secure by design — Inside and out
The DG505G is not just an edge device — it’s a gateway to safe digital operations. It’s constructed from industrial-grade materials that operate consistently through the toughest conditions — from isolated oil production sites to utility substations and field monitoring stations.
It’s designed to support enterprise network security requirements, too, with encrypted interfaces and secure boot procedures that secure firmware and data.
Key Features
- Rendering of CBRS and Private LTE Network Support
- Enhanced Security Features for Data Flow Encryption
- Industrial-Grade Toughness for Harsh Environments
- Simple Plug-and-Play Installation through USB Interface

The outcome is an industrial-grade secure enterprise CBRS solution with simplicity.
DG505G in action: Secure connectivity across every industry
1. Utilities and grid infrastructure
Utility networks need always-on, end-to-end encrypted communication channels from field units to control systems. DG505G is a Private LTE gateway for utilities, authenticating every connection with SIM-based authentication and providing unbroken data transmission across large geographic areas.
2. Oil & gas and energy
Field engineers and monitoring equipment working in challenging or remote environments are supported by the rugged enterprise CBRS router feature of the DG505G. Its secure, SIM-verified connection safeguards against interference and data spilling even within solitary networks.
3. Smart infrastructure and IoT
For IoT devices like gateways, meters, and weather sensors, the high-performance CBRS modem for IoT provides secure, authenticated communication. Each device connected through DG505G is a trusted one in the network — unauthorised access becomes all but impossible.
4. Industrial automation
Industrial CBRS LTE/5G routers used in factories and industrial equipment utilise the DG505G as a rugged, plug-and-play modem for equipment testing, remote monitoring, and telemetry. Its compact size and USB connectivity make it well-suited for small systems.
SIM-Based security vs traditional authentication
Unlike systems that rely on software credentials or shared network keys, SIM-based security builds authentication directly into hardware. This approach delivers several critical advantages:
- Feature Traditional Authentication SIM-Based Authentication
- Identity Management Software or user credentials , Unique SIM hardware ID
- Data Protection Password-based encryption LTE/5G-level encryption
- Access Control User-managed Network-managed, tamper-proof
- Set up Process Manual configuration Plug-and-play verification
- Scalability Limited : Automatically scalable across devices
This is why Horizon’s DG505G is trusted by organisations that operate in mission-critical, high-security environments, where a single unauthorised connection could compromise entire operations.
Private networks, Public confidence
DG505G is engineered specifically for CBRS (Citizens Broadband Radio Service) — shared spectrum that allows organisations to roll out private LTE or 5G networks.
Through the integration of Band 48 high-reliability routing features with SIM-based authentication, Horizon enables enterprises to create stand-alone, highly secure wireless infrastructures that don’t rely on traditional carriers.
DG505G private networks can establish their own security groups, user groups, and access policies. All devices on the network are authenticated using their SIM, providing end-to-end visibility and control of who and what is present on the network.
The horizon approach to network security
Security is not an afterthought at Horizon but a starting point. All products, from routers to dongles, are built upon multi-layer protection and zero-trust approaches.
The DG505G is a great example of this approach by adding security at the hardware, software, and network levels:
- Hardware Layer: Secure SIM based on hardware and chip-level encryption.
- Software Layer: Firmware signed and verified prior to activation.
- Network Layer: LTE/5G encryption, mutual authentication, and session-based trust refresh.
Through these layers, combining, the DG505G allows organisations to construct networks that are not just connected, but secure against today’s sophisticated cyber threats.
