With this overview, we wish to assist
you in selecting the ideal remote
communication solution for your
application. Consider the advantages and
costs that the various systems involve and
opt for a solution that is ideally suited to
your requirements.
Wired
systems
Various communication methods are
available for data transmission to
remote or widespread networks or for
monitoring machines all over the world.
The transmission methods involved are as
individually structured as the applications
are different.

What is GPRS/EDGE/3G?
Mobile phone services that transmit TCP/IP-based data packets via the
mobile phone network. These services encompass the third mobile
phone generation (3G) standards, such as UMTS, HSPA, GPRS, and
EDGE, that operate in the GSM network. They divide data into small
packets and subsequently send it, a process that is dubbed packet
switching. The volume-dependent billing of IP data packets reduces the
transmission costs, the reason being that it is only necessary to pay for
the quantity of data that was actually sent and/or received.
What is SMS?
SMS (Short Message Service) is a service for transmitting text messages
in GSM networks. The text messages can contain up to 160 characters
and be used for alarm generation and the transmission of status
information.
What is GSM?
GSM (Global System for Mobile Communications) is a standard for
digital mobile phone networks that is used in more than 200 countries.
The following four frequencies are used worldwide: 850 MHz,
900 MHz, 1800 MHz, and 1900 MHz. GSM data connections to
telephone numbers featuring speeds of up to 14,400 bit are billed
according to connection duration.

What is an analog fixed-line network?
Worldwide data connections can be implemented with the aid of
the public telephone network. A dial-up connection is established
in accordance with international standards. Carrier sequences
serve the purpose of synchronizing the two modems in this regard.
The maximum performance of such a full duplex - point-to-point connection is 33.6 kbps.
What is ADSL?
ADSL (Asymmetric Digital Subscriber Line) is a transmission method
for a broadband Internet connection via a normal telephone line in the
public telephone network. Depending on the ADSL standard that is
used (ADSL/ADSL2/ADSL2+ according to Annex A or B), transmission
speeds of up to 25 Mbps are possible.
• Annex A (in most countries): DSL operation in parallel with analog
telephony (PSTN/Public Switched Telephone Network)
• Annex B (Germany and neighboring countries) DSL operation in
parallel with digital telephony (ISDN/Integrated Services Digital Network)
What is SHDSL?
SHDSL (Symmetric Digital Subscriber-Line) is a DSL access technology
via a two-wire cable. Data can be transmitted at up to 30 Mbps in both
directions. Distances of up to 20 km are possible.

What is Trusted Wireless?
Trusted Wireless 2.0 is a wireless technology that has been especially
developed for industrial applications. The FHSS method is used for band
spreading, which guarantees a high degree of immunity to interference.
The adjustable data rate of the wireless interface enables the data
rate to be adapted to the requirements of the relevant application.
Trusted Wireless features large ranges (typically up to 5 km), the
cyclical transmission of small, non-time-critical signal packets, and good
diagnostics.
What is WLAN?
WLAN (Wireless Local Area Network) refers to a local wireless
network with a data rate of up to 54 Mbps. Since WLAN systems
integrate well in IT networks, they are ideal for mobile operation
and monitoring, as well as data acquisition. Protocol-transparent
transmission allows communication with mobile controllers.
What is Bluetooth?
Bluetooth is a standard for wireless communication over short
distances involving up to seven devices. Bluetooth uses the 2.4 GHz
ISM band as a transmission medium. This frequency band is available
free of charge throughout the world without any need for a license.
A frequency jump method is used to establish robustness vis-à-vis
disturbances.
