The difference between 4G Industrial Router and 4G DTU is explained in Detail
4G industrial router and 4G DTU both realize the
wireless network data transmission function, and the differences between them
are mainly from the use method, appearance interface and application
environment, etc. Today, we will introduce some differences between 4G router
and 4G DTU.
Different methods of use:
4G industrial router:
The 4G router can convert Ethernet and fieldbus
communication protocols. It only needs to set the IP address specified by the
4G router in the terminal device as the gateway. If the specified IP address
(or the specified IP address segment) is not set, the communication function
cannot be realized.
4 g DTU:
The main purpose of 4G DTU is to realize dial-up
rather than a real gateway. For example, 4G DTU can be used as a new network
device after the dialing process of the access terminal device is completed,
and the terminal device address can be used as the binding address of 4G DTU.
Different application environments:
4G router: usually with VPN/APN function, with
private network encryption, in addition, the industrial 4G router with WIFI
function is suitable for outdoor WIFI wireless signal coverage projects and
similar public transport WIFI and shopping mall WIFI sharing projects.
4G DTU: the transmission distance of field terminals
is relatively scattered and the data communication rate is relatively high, so
the real-time performance of 4G DTU can meet the requirements of most
industrial fields and is usually used for data acquisition and monitoring
system. For example, the charging pile remote monitoring system, environmental
monitoring system, real-time monitoring of energy consumption, monitoring and
application of dam water conservancy projects, etc.
Different network interfaces:
4 g router: provides one network interface of data
access, terminal equipment needs only the IP address of the mouth to the 4 g
router in the network as a gateway to the IP address of the terminal device
must use specified or specify the IP address in the address period, 4 g router
to and specify the IP address of the server host or server host IP address
sections for data exchange, and all the other 4 g router is not set between the
address of the can't communicate.
4 g DTU
4 g DTU: DTU data access in general also provides a
serial port or network interface, but their use is used to dial, not used to do
in the true sense of the gateway, such as serial interface 4 g DTU after
completion of the access terminal dial-up, 4 g DTU as terminal equipment of a
new network equipment, terminal equipment address using the new network
equipment binding address; However, 4G DTU of network interface is similar to
ADSL of telecommunication to connect to the Internet, which generally requires
the device to complete a dial-up action.
Different anti-interference of server network:
When using 4G router, the data
transmission must comply with the preset regulations, otherwise, the correct
communication cannot be carried out, reducing the possibility of unnecessary
network traffic; at the same time, according to the sent serial number and
other key processing, to ensure that the server data will not be replay or
retransmission.
4G DTU does not carry out relevant filtering during
data transmission, so other machines can directly send some illegal information
to the device terminal through the network. Meanwhile, 4G DTU increases
unnecessary network traffic. At the same time, the data is not processed
accordingly, which may lead to the replay or retransmission of wireless data,
which will lead to the abnormity of the system, thus causing potential security
risks.
The E-Lins Technology H685 series 4G router
with Ethernet is a compact, ruggedized 3G/4G/LTE cellular 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. Super mini size suitable for embedding
applications.
In addition to the robustness, reliability, security,
friendly-using, the H685 4G router with Ethernet is competent to be engineered
