Introduction Video

The E-Lins H820Q Series 4G WiFi Router is a compact, ruggedized 3G/4G/LTE and Dual Band Wi-Fi (2.4Ghz + 5Ghz) networking solution designed for mission-critical connectivity in the most challenging environments. It is qualified for M2M (Machine to Machine), IoT (Internet of Things) and In-Vehicle applications.

With an extensive list of safety and hardening certifications, the H820Q 4G WiFi Router is engineered to protect against extreme temperatures, humidity, shocks, vibrations, dust, reverse polarity, and transient voltage, which is widely used in more than twenty industrial fields, such as CCTV security surveillance, vehicle, Telemetry, vending machines, power control, AMR, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other areas.

Highlights

Supports LTE Advanced with SIM-based auto-carrier selection; Cellular/WAN RJ45/WiFi client failover and Load Balance (Bandwidth link bonding); Cloud-managed (with NMS network management system), TR-069, Web management, SMS, SSH/Telnet/Command, SNMP; Dual-band, dual concurrent WiFi (802.11 a/b/g/n/ac, 2.4Ghz + 5Ghz); Certified 3G/4G/LTE enterprise/industrial grade internal modems; Built-in transient and reverse polarity voltage protection; 5–40V DC voltage input range (5-60V DC option), Dual Power Inputs / Power Failover; GPS / GNSS support; Multi-carrier 4G LTE support with SIM card slot; Supports Ethernet (T1, DSL, Cable, MetroE), WiFi as WAN, and Metro WiFi; Ruggedized to ensure always-on connectivity; Create real-time alerts to monitor uptime; Offer secure, guest WiFi to passengers; Advanced security, VPN, and stateful firewall to protect sensitive data; Robust Metal Case is ruggedized for vibration, shock, provide IP30 protection; Desktop, Wall-mount and Din-rail mount of installation;

To further enhance the wireless M2M and IoT reliability, the H820Q 4G WiFi Router 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 H820Q 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 H820Q 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 H820Q 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

Industrial design, 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 H820Q SIM card WiFi router 4G 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

Dual Band or Tri band Concurrent WiFi with Wave2 and MU-MIMO

The H820Q SIM card WiFi router 4G built-in 2.4GHz Wi-Fi default. Option 2.4Ghz + 5GHz dual band or tri band WiFi with concurrent data transmission to achieve high powerful WiFi performance. Also it supports high gain WiFi module including 802.11AC Wave2 and MU-MIMO technology for installation and replacement to meet different WiFi requirement.

With multi radios, H820Q gets 2~3 times number of served clients comparing to normal single radio.

With multi data stream, H820Q gets 3~4 times data bandwidth comparing to normal single data stream.

With MU-MIMO technology, H820Q gets 2~3 times data bandwidthand and number of served clientscomparing to normal single radio single data stream.

H820Q SIM card WiFi router 4G supports high gain WiFi replacement to meet different applications.

VPN Safety and Securiy

Offer 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 Input

The H820Q 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 H820Q 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.
