PUSR has launched the USR-G806-A industrial 4G LTE cellular Wi-Fi router. With its all-scenario coverage capability, industrial-grade reliability, and rich functional configurations, it has become the preferred solution in the fields of industrial IoT, smart cities, and remote monitoring in the US market.
1. What is the USR-G806-A? - The Definer of US Cellular Wi-Fi Routers
The USR-G806-A is a 4G LTE cellular Wi-Fi router specifically designed for industrial environments in the US region. Its core function is to provide multi-link redundant communication capabilities for devices by integrating a 4G/3G cellular network module, a Wi-Fi wireless local area network (WLAN), and dual Ethernet interfaces. The product features a metal casing (IP30 protection rating) and supports operation in a wide temperature range from -20°C to 70°C, adapting to harsh environments such as high humidity and strong electromagnetic interference. It can operate stably in scenarios such as outdoor surveillance, industrial automation, and traffic management.
Product Positioning: The "Communication Hub" of US Industrial IoT
The USR-G806-A is not positioned as an ordinary home router but rather as an edge communication gateway for industrial IoT (IIoT). It undertakes key tasks such as device data collection, remote transmission, protocol conversion, and security protection. Its design philosophy revolves around "high reliability, low latency, and easy management." It supports global mainstream operator networks (full 2G/3G/4G frequency band coverage) and is compatible with the frequency bands of operators in North America, such as AT&T, Verizon, and T-Mobile (e.g., FDD-LTE Band 2/4/12, WCDMA Band 2/4/5), ensuring seamless coverage in the US mainland and remote areas.
2. Why is it Called a "US Cellular Wi-Fi Router"? - Deep Adaptation to North American Communication Standards
The term "US Cellular" directly highlights the product's regional adaptability and communication standard compatibility. The USR-G806-A has become synonymous with cellular Wi-Fi routers in the US market through the following technical characteristics:
2.1 Full Coverage of North American Frequency Bands
The product supports FDD-LTE Band 2/4/12 and WCDMA Band 2/4/5, covering the 4G/3G network frequency bands of mainstream US operators (AT&T, Verizon, T-Mobile). For example, Band 12 (700MHz) is Verizon's core low-frequency band in rural areas of the US, and the cellular Wi-Fi router USR-G806-A can ensure a stable connection in remote regions.
2.2 Operator-Grade Certification and Compliance
The product has passed US FCC certification and complies with electromagnetic compatibility (EMC) and safety standards in North America (such as UL certification). It can be directly deployed in scenarios with stringent compliance requirements, such as bank ATMs and smart parcel lockers. In addition, it supports APN/VPDN private network card functions, meeting the needs of enterprise-level users for data isolation and secure access.
2.3 Localized Services and Technical Support
PUSR has established warehousing and technical support centers in the US, providing 7×24-hour technical response and rapid spare parts replacement services to ensure users have no worries during use.
3. Functions and Advantages: The "Hexagonal Warrior" of Industrial-Grade Communication
The functional design of the cellular Wi-Fi router USR-G806-A is centered around the core needs of industrial scenarios, forming differentiated advantages of "high reliability, high security, easy management, and low cost."
3.1 Multi-Link Redundancy and Automatic Switching
Dual Ethernet Interfaces: It supports one WAN port (connecting to a wired network) and one LAN port (connecting to local devices), which can be configured in "primary-backup link" or "load balancing" modes. When the 4G network or wired network is interrupted, the router automatically switches to the backup link to ensure zero interruption of data transmission.
VPN Tunnel Detection: It supports mainstream VPN protocols such as PPTP, L2TP, IPSec, OpenVPN, and GRE and has tunnel health monitoring functions. If the VPN connection is abnormal, the router can automatically reconnect or switch to a backup tunnel to ensure the security of remote access.
Multi-Level Link Detection: Through technologies such as hardware watchdogs, heartbeat detection, and ICMP probing, it monitors the network status in real time. If a link failure is detected, the router will trigger automatic redialing or rebooting, with a recovery time of less than 30 seconds.
3.2 Industrial-Grade Hardware Design
Wide Temperature Operating Range: The operating temperature ranges from -20°C to 70°C, and the storage temperature ranges from -40°C to 75°C, adapting to extreme environments in northern cold regions (such as Alaska) or southern high-temperature regions (such as Texas) of the US.
High Protection Rating: The metal casing (IP30) is dustproof and can withstand minor collisions. Its anti-electromagnetic interference capability meets the IEC 61000-4-3 standard, ensuring stable operation in strong electromagnetic environments such as substations and factories.
Low Power Consumption Design: The operating voltage is DC 5~36V, with an average current of 120mA (DC12V). It supports solar power supply systems and is suitable for outdoor scenarios without mains power access (such as environmental monitoring stations and agricultural irrigation equipment).
3.3 Data Security and Privacy Protection
Firewall Functions: It supports NAT, access control lists (ACLs), DDoS defense, IP-MAC binding, etc., which can block illegal access requests and protect the security of internal network devices.
VPN Encrypted Transmission: Through AES 256-bit encryption algorithms, it ensures the confidentiality of data during transmission over the public network, meeting the stringent requirements of industries such as finance and healthcare for data privacy.
SIM Card Management: It supports APN automatic detection, SIM card information display, and private network SIM card binding to prevent SIM card theft or misinsertion.
3.4 Intelligent Management and Operation and Maintenance
Remote Management Platform: It supports SSH, WEB, TELNET, and PUSR cloud platform management. Users can monitor the router status, configure network parameters, and upgrade firmware in real time through PCs or mobile apps.
Traffic Control and Alarms: It can set data traffic thresholds and automatically send alarm emails or text messages when the traffic exceeds the limit, avoiding additional costs due to traffic overruns.
Log Audit Function: It records device operation logs, network connection logs, and security event logs, facilitating post-event tracing and compliance auditing.
