Failover, Load Balancing and Link Bonding of 4G Router External Antenna

To further enhance the wireless M2M and IoT reliability, the H685 4G router with Ethernet provides multi-connection for get different applications.

1) Failover

With this using, usually you can get one SIM Cards from the mobile network, get one xDSL modem line and WiFi AP (conneced to Internet or Private Networks). Set the main line, backup lines for failover application. Once the main line is failed, the H685 switches to backup line smoothly, which makes the communication stable and reliable. .

2) Load Balancing and Link Bonding

Being a 4G Load Balancing Router, the H685 can utilise the embedded 4G module, the RJ45 WAN and WiFi Client connections all at the same time and share these WAN connections with the LAN users.

With channel link bonding, the H685 4G router makes two or more links are combined for redundancy or increased throughput. Channel bonding is differentiated from load balancing in that load balancing divides traffic between network interfaces on per network socket (OSI model layer 4) basis, while channel bonding implies a division of traffic between physical interfaces at a lower level, either per packet (OSI model Layer 3) or a data link (OSI model Layer 2) basis.

E-Lins has a better industrial design

Industrial Design. Rubust and Working in Wide Range Temperature

H685 4G router with Ethernet is industrial designed, excellent function to ensure 7x24h running in stability and reliability;

Wide range power input with dual types of input supported; Alloy-metal case, IP30 protection standard;

Quality industrial grade casing provides robust and reliable 4G router for installation in many different environments and operating temperature of -35 Celcius to +75 Celcius.

With Multi-Powerful-Features

Built-in Industrial Modem Module and SIM Card Slot

The H685 can built-in industrial class radio modem module to provide rubust and reliable cellular network communications. With SIM Card Slot, users can insert a SIM to dialup 2G/3G/4G networks directly.

Rich Interface

VPN Safety and Securiy

H685 4G router external antenna offers more VPN safety application schemes, data transmission reach to financial grade standard E-Lins wireless routers support APN/VPDN private networks, also including various VPN access such as IPSEC, PPTP, L2TP, GRE,OPENVPN, DMVPN, etc. including the function of VPN client and server. Add one more channel of encryption communication under the base of special network can fully guarantee the safety and accuracy of data of dealing and management.

Dual Power or Tri Power Input

The H685 smart 4G Router supports wide voltage range of 5V to 40V DC (option up to 60V DC) and has two power inputs so if the primary power fails then the modem will automatically use the second power supply without link downtime.

Three Types of Installation (Din-rail, wall-mount, Desktop)

GNSS / GPS is supported

Multi-management

Supporting Web GUI, Telnet SSH Command, SMS, TR-069, SNMP, and NMS (E-Lins Network Management System), users can manage and control the H685 4G router external antenna easily and flexibly.

All E-Lins communication terminals can be connected to the E-Lins remote managing and controlling platform (NMS), which brings the generous devices scattering in different areas to carry out concentrate monitor, configuration, updated, diagnose, maintenance, manage and control. Highly reduce the maintenance costing in the operator, integrator, devise supplier etc, increase the managing efficiency.

Industrial Applications

  • Remote data monitoring & control (SCADA / telemetry)
  • CCTV & security surveillance backhaul
  • AMR automatic meter reading — water, gas, oil flow
  • Power station & distribution network supervision
  • POS terminals, ATM & vending machines
  • Traffic signal & street lamp monitoring
  • Fleet management & vehicle diagnostics
  • Hydrologic / weather station data acquisition
  • Telecom base-station equipment supervision

Always-Online Failover

Cellular, wired WAN and Wi-Fi client back each other up automatically. When one link drops, traffic switches in seconds — your SCADA polling never notices.

Serial DTU for Legacy Devices

Optional RS232/RS485 port bridges Modbus RTU meters and decades-old controllers onto IP networks. No forklift upgrade — the serial device just gains a 4G link.

Full VPN Suite On Board

IPsec, L2TP, PPTP and GRE tunnels terminate directly on the router. Site data reaches your platform encrypted, without extra security appliances.

Built for Outdoor Cabinets

Wide-temperature components, enhanced ventilation and a compact metal body fit cramped street cabinets and survive them. Rated for −35 °C cold starts to +75 °C summer heat.

Self-Healing Watchdog

A hardware watchdog plus multi-layer link detection restarts frozen links before anyone calls you. Unattended sites keep working for years, not weeks.

Fleet Management via NMS

Every H685T reports signal, traffic and status to E-Lins NMS cloud. Push configs and firmware to one unit or ten thousand — from a single dashboard.
