Long Term Evolution (LTE)Technology OverviewLong Term Evolution (LTE) will ensure the competitiveness
of UMTS for the next ten years and beyond by providing a
high-data rate, low-latency and packet-optimized system.
Also known as E-UTRA (Evolved Universal Terrestrial Radio
Access), LTE is part of 3GPP Release 8 specifications. The
innovations that LTE brings to the UMTS world include:
❙ New multiple access schemes for both LTE FDD and TD-LTE
❙ Scalable bandwidth up to 20 MHz
❙ MIMO antenna technology
❙ New data and control channels
❙ New network and protocol architecture
❙ Specific test and measurement challenges
Commercial LTE networks have been launched world-
wide, starting with the first network in Sweden in Decem-
ber 2009. 3GPP Release 9 features added further enhance-
ments to LTE. The 3GPP candidate technology submission for
IMT-Advanced, developed as LTE Release 10 and beyond, has
been accepted as a 4G technology. Known as LTE-Advanced,
it complies with or exceeds the ITU established criteria in all
aspects.
Rohde & Schwarz is the right partner for making your
LTE products happen. Our test solutions were the first
on the market and since then have evolved to a full
product portfolio from a single-source supplier, covering
applications from R & D to conformance.
