The Mobile Wireless Standard Of The 5Th Generation - Siemens SIMATIC NET System Manual

Basics of communication with Industrial Ethernet
1.6 Industrial Wireless Control
LTE (3.9G)
LTE stands for Long Term Evolution and is known as the 3.9G standard because it does not
completely implement the 4G specification of the ITU-T standard. It supports six different
bandwidths between 1.4 and 24 MHz and allows transmission rates up to 300 Mbps. The
maximum data rate is only achieved when using 4x4 MIMO (multiple antenna technology).
The high transmission rate and IP-based packet switching allow the transfer of language via
TCP/IP ("Voice over IP"). In industrial applications, it facilitates maintenance via smartphone
or tablet.
LTE Advanced (4G)
LTE Advanced or also 4G is a protocol extension fro LTE. It provides transmission rates up
to 1000 Mbps and is downward compatible to LTE. The high data transmission rate allows
real-time access. A further advantage is a higher number of users that can be active at the
same time.

The mobile wireless standard of the 5th generation

Properties and goals
The new 5G standard offers significant improvements in the following fields compared to the
previous standards:
● Data transmission rates and width of the frequency spectrum
This property is referred to as Enhanced Mobile Broadband (eMBB).
● Device density per unit of area
The scenario Massive Machine-Type Communication (mMTC) is of great importance for
industrial applications, both for the Internet of Things and in the process industry.
● High reliability and low latency
The designation Ultra-reliable low-latency communications (URLLC) has established itself
for this requirement.
The individual 5G functions are being implemented in stages: eMMB is planned for Release
15, mMTC and URLLC for Releases 16 and 17.
