Apr 29, 2010 - Rohde & Schwarz, an active
member of the 3GPP consortium, has
assembled a package of informative material
about the latest developments of
LTE-Advanced. The introductive material about
LTE enhancements together with first test
solutions make it easy to gain an
understanding of LTE Release 10 and later.
While initial LTE networks have been
commercially launched, further enhancements
are gaining importance in order to comply with
the IMT-Advanced requirements specified by
the International Telephone Union (ITU).
Enhancements include the downlink and uplink
path as well as further novelties related to the
transmission technology, which are described
in application note 1MA169 and are also
outlined on a poster.
IMT-Advanced represents a true 4th generation
system. It determines data rates of 100 Mbit/s
for high mobility and 1 Gbit/s for low mobility to
support advanced services and applications.
3GPP proposes LTE from Release 10 (i.e.
LTE-Advanced) on as a candidate technology
for IMT-Advanced, to provide operators running
LTE networks with an evolutionary path toward
a true 4G system. Although a rollout of
LTE-Advanced is at least five years away,
power amplifier manufacturers can already
consider the requirements and are now looking
for signal generation and analysis solutions.
Rohde & Schwarz test solutions for LTE were
the first on the market and have since evolved
into a full product portfolio. The modular and
highly flexible solutions can easily be extended
to cover LTE Advanced test requirements.
Early test requirements such as carrier
aggregation can be implemented with Rohde &
Schwarz signal generators and analyzers. For a
detailed description of the test instrument
settings, see application note 1MA166 below.

The trend toward mobility cannot be stopped. In
addition to the well-established cellular mobile
radio standards, numerous complementary
technologies based on radio frequency have
evolved. This includes wireless connectivity
standards such as Bluetooth® and WLAN that
pave the way for personal device-device
connectivity, navigation standards such as
GPS, etc.
The increasing popularity of the wireless world
requires that the different standards work hand
in hand, interference-free...
