The document discusses M2M equipment and an industrial 4G router. It provides an overview of M2M communication protocols and applications. It then describes the features of an industrial 4G router, including multi-carrier cellular and WiFi support, cloud management, GPS, serial ports, I/O ports, security features, and ruggedized casing. Finally, it lists several IoT industry applications for the 4G router such as finance, transportation, public security, utilities, industry, and more.

1. Overview – M2M Equipment’s Manufacturer
M2M is an abbreviation of Machine-to-Machine/Man. It is a kind of networked
application and service centered on the intelligent interaction of machine terminals.
The M2M protocol specifies the communication protocols that human-machine
interactions need to comply with. With the development of science and technology,
more and more devices have communication and networking capabilities, and
network everything has gradually become a reality. Communication between people
needs a more intuitive, exquisite interface and richer multimedia content, and M2M
communication needs to establish a unified and standardized communication
interface and standardized transmission content. In addition, but in a broad sense,
M2M can represent the connection and communication between machine to
machine, man to machine, machine to man, and mobile to machine. It covers all the
technologies and means of establishing a communication link between people,
machines and systems. The development of M2M of M2M application market is
rapidly growing worldwide. With the deepening of related technologies including
communications equipment and management software, the cost of M2M products
will decline, and M2M services will gradually mature.

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

2. 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
More Highlights
Industrial Design. Robust and Working in Wide Range Temperature
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.
Built-in Industrial Modem Module and SIM Card Slot
The 4G Router 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.
VPN Safety and Securiy
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.

3. Dual Power or Tri Power Input
The 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.
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.
