Cellular Standard
Cellular technology is commonly referred to by "generation," such as 1G, 2G, and so on, in which 1G is the first
generation analog cellular technology. The primary difference between 2G/2.5G and 3G is the speed at which data is
transferred over the network.

number of key benefits to business.
• Mobility and Increased Efficiency
Adding mobility to your operation, and
improving your ability to connect to remote
access devices can lead to increased
efficiency.
• Wide Transmission Range
Cellular technology allows you to connect to
devices from a wider range of locations. You
can send and receive information at any time
without any limitation.
• Better Security
Since cellular providers use heavily restricted
and well-defined bands for their networks,
cellular signals are considered very secure
and not vulnerable to eavesdropping or signal
interception.
• Cost Effective
In a factory setting, for example, using a
cellular solution can reduce cost and time
required for cabling maintenance and
installation. Cellular technologies also allows
for easier device installation and maintenance.
Cellular Solutions from Moxa
Moxa offers advanced cellular solutions to connect intelligent or
non-intelligent devices to GSM/GPRS networks:
• OnCell G2150I, G2110, and G2110-T cellular modems – The
OnCell G2100 series of cellular modems are designed to
transmit data and short messages (SMS) over GSM/GPRS
mobile networks. The modems can help increase the efficiency
of maintenance and communication of remote serial devices,
independent of operating skill.
• OnCell G3110 and G3150 cellular IP modems – The OnCell
G3100 series of cellular IP modems are designed to connect
non-intelligent devices to GSM/GPRS/EDGE cellular
networks. Each modem comes pre-installed with the TCP/IP
protocol suite to exchange data between the serial device
and cellular TCP/IP network. They also feature a number of
operation modes for easy integration into your applications
without significant change to your software. Supported
operation modes include TCP server, TCP client, Real COM,
and Reverse Real COM.

software to transmit data over the cellular network, even though
the software was originally designed to transmit data over a

versatility, and helps to reduce the total operational cost.
Benefits
Cost
Moxa’s IP modem supports high-speed GPRS, which can be used to establish a reliable, always-on connection.
Since users are charged by the amount of data that is transmitted, this solution can result in lower monthly charges
for remote applications that are not data-intensive.
Security
Standard TCP/IP Architecture
There are three modes that are supported: TCP Server, TCP
Client, and UDP. Whichever mode is used, once a connection is
established, the two sides of the connection can both send and
receive data.
Moxa’s IP modem builds a secure TCP/IP connection using advanced data encryption and authentication
technologies. Users can easily set up the connection without modifying the existing software applications on the
control side.
