Load balancing functions can be used with E-Lines's dual-sim router. It can utilise the two embedded 4G modules, the wired WAN and Wi-Fi client connections all at the same time and share these WAN connections with the LAN users. Learn more at http://www.e-lins.com/EN/.

E-Lins 4G Router Load Balancing Between Dual Sim
Load balancing (Load Balance) is a kind of cluster servers or network equipment
technology. Load balancing allocates specific services (such as network services and
traffic) to multiple servers or network devices to improve service processing
capability and ensure high service availability. The basic concepts of load balancing
include real services, real service groups, virtual services, scheduling algorithms, and
persistence. Common load balancing scenarios include SLB and link load balancing.
Based on the existing network structure, load balancing provides a cheap and
effective method to expand the bandwidth of network devices and servers, increase
the throughput, strengthen the network data processing ability, improve the
flexibility and availability of the network. Note that a load balancing device is not a
basic network device but a performance optimization device. For network
applications, load balancing is not necessary at the beginning. When the traffic
volume of network applications continues to increase and a single processing unit
cannot meet the load demand, the network application traffic bottleneck will occur.
Why do you need load balancing?
Take scenes from our own lives. We often have to go to some crowded places, such
as subway stations, train stations, cinemas, banks and so on. Whether buying tickets
or queuing for admission, these places will generally set up multiple service points or
entrances. In most cases, the nearest entrance will be crowded if there is no one to
guide it. The service points or entrances that are far away are much looser. If these
queuing people can be well dispersed to each entrance, it will greatly shorten the
queuing time. Load balancing acts as a coordinator to evenly distribute requests from
these users.
The LB function of the E-Lins router can be used for any two cells, wired WAN or Wi-
Fi client. In addition, only dual modem dual sim routers can support Cell and Cell.
E-Lins dual modem dual sim 4G router also supports sim switch. Only one of the two
modem works and the other one standby. E-Lins routers also support failover
between wan, Wi-Fi, and cells. If LB is enabled, both sim switch and failover must be
turned off.
Industrial design of E-Lins router: rail mounting, gold-plated housing, industrial-grade
high-speed 4G module.

The industrial router is installed with guide rails, and small holes are reserved on the
side to directly hang industrial clips and install them on the guide rails. At the same
time, you can also freely combine the mounting ears for installation, which is
convenient for fixing equipment and reducing transmission interference; the gold-
plated shell improves appearance protection The high-speed industrial-grade 4G
module provides corresponding protection for the harsh environment of severe cold
and high temperature. At the same time, it is equipped with a 32-bit high-
performance processor to transmit high-definition Video, high-definition pictures
and other front-end collection information transmission is more high-speed and
stable.
