High-Speed Wi-Fi Hotspot with ICR-1745

Introduction

The ICR-1745 is a compact and cost-effective industrial 5G connectivity gateway designed to provide reliable wireless communication for distributed and remote deployments. Built on future-proof 5G NR technology, it delivers low latency and stable data transmission for applications where real-time connectivity and operational continuity matter. 

With five Gigabit Ethernet ports, digital I/O, and serial interfaces, the ICR-1745 easily connects both IP devices and legacy equipment to modern 5G networks. Integrated VPN support, connection monitoring, and automatic recovery mechanisms help ensure secure and resilient operation, even in unattended or harsh environments. 

Its flexible system-on-module design, combined with the open Linux-based ICR-OS platform, allows customization through scripts, C/C++, or downloadable RouterApps to extend standard firmware functionality. The router is also easy to manage at scale via WebAccess/DMP, a cloudbased platform for device management, provisioning, and monitoring – making it ideal for mass deployment, remote management, and secure VPN access. 

Whether for environmental monitoring, mission-critical machinery, IP surveillance, or providing high-speed Wi-Fi hotspots, the ICR-1745 acts as a versatile building block, supporting a wide range of industrial M2M and IoT applications. The following use cases illustrate how it can be deployed to deliver reliable connectivity, enhanced operational efficiency, and seamless integration into complex networks.

Challenge

Events, remote offices, or temporary sites often require fast and reliable internet access for multiple users simultaneously. Traditional connections may be limited in bandwidth or unstable, resulting in slow performance and frustrated users.

Solution 

The ICR-1745 combines 5G connectivity with Wi-Fi 6 to provide reliable high-speed internet for multiple users. Integrated VPN support, continuous monitoring, and centralized management via WebAccess/DMP allow administrators to configure, monitor, and maintain the network efficiently, even across multiple locations. The router’s robust design ensures stable performance under heavy loads and in diverse deployment environments.

Benefits

 • High-speed internet access for multiple concurrent users

 • Reliable Wi-Fi 6 performance combined with fast 5G uplink

 • Secure network operation and traffic control using VPN and firewall features

 • Centralized hotspot and device management via WebAccess/DMP

Use Scenario

Multiple ICR-1745 routers provide high-speed Wi-Fi in a city park, a public bus, and residential homes. Each router uses 5G for uplink and Wi-Fi 6 for local connectivity. The security layer, including 802.1X Authenticator and Captive Portal, ensures authorized access, while administrators monitor and manage all hotspots centrally via WebAccess/DMP, maintaining fast, stable, and secure network access.
