1.1 Brief Introduction
ER-701T is a high speed 4G/WAN router. It works in
LTE-TDD/LTE-FDD 4G networks, and can access internet and transfer
video and data with high speed. In LTE-TDD network, in theory the
uplink speed can reach 18Mbps, and downlink speed can reach
61Mbps; and in LTE-FDD network, in theory the uplink speed can
reach 50Mbps, and downlink speed can reach 100Mbps.
ER-701T can use WAN or WIFI network as well: in case cable network
is available, WAN (LAN0) port can be used to access cable network;
and in case WIFI is available, ER-701T can be configured to access
internet via WIFI. 4G, WAN and WIFI are all supported by ER-701T,
this greatly facilitates customer’s project deployment that customers
do not have to choose different devices from different suppliers
because of different network access at the spot. This can not only save
procurement cost, but also reduce maintenance effort for the projects.
Comparing with eTung’s MR-900T 4G router, ER-701T has extended 4
Ethernet interfaces, and can connect 4 PCs via Ethernet cable at the
same time. Thus when customers have multiple PCs at the spot that
need to access the internet, they do not have to deploy additional hub
or wireless communication devices. This can reduce device
procurement cost and maintenance cost as well.

ER-701T has WIFI AP functionality as well, and supports 802.11b/g/n
protocol. In theory the highest speed can be 150Mbps. Either mobile
phones, PCs or other devices that has WIFI functionality, can bind
Er-701T’s WIFI access point and share Internet access via ER-701T.
This greatly extends the number of devices that can connect with
ER-701T at the same time. Meanwhile, with ER-701T’s WIFI and
extended Ethernet interfaces, customers can build a small local area
network, and all devices that connect to ER-701T via WIFI or physical
Ethernet cable are in the same local area network, and can
communicate each other freely.
ER-701T has built-in WEB configuration interface, and is easy to use.
ER-701T supports static routing, DMZ host, port forwarding and VPN,
and has performance tuning function for high speed wireless
applications as well. It can work stably and reliably in unattended
environment.
ER-701T can connect quickly with web camera, video server, PLC and
IPC, and transfer data from the customer device that connects with
ER-701T to a host in the internet, so as to transfer data remotely and
transparently. ER-701T can be widely used in industries such as
banking, road transportation, power system, environment protection
and industrial controlling.

Attention: in practice, it is suggested to use both master and slave antennas
at the same time; and if only one antenna is in use, it must connect to master
antenna interface.

1.5 Working Mechanism
Figure 1-14: ER-701T working mechanism
PC connects to one of ER-701T’s LAN interfaces with a cross cable.
After power on it dials via 4G wireless network (or: connects with WAN
cable network or WIFI) and connects to the internet, then PCs can
share the internet via ER-701T, and access the application server. At
the same time, using ER-701T’s WIFI functionality, PCs (or other
devices that support WIFI) can connect to ER-701T’s WIFI access
point, instead of connecting with Ethernet cable, to share the Internet
access.
Meanwhile, ER-701T can be used to build remote virtual LAN with VPN,
monitor video remotely, and publish programs remotely on LED color
screens, etc.
