Does 4G LTE use MIMO?
Does 4G LTE use MIMO?
MIMO, Multiple Input Multiple Output is a technology that was introduced into many wireless communications systems including 4G LTE to improve the signal performance. Using multiple antennas, LTE MIMO is able to utilise the multiple path propagation that exists to provide improvements in signal performance.
What are the new functionalities of LTE A?
The main new functionalities introduced in LTE-Advanced are Carrier Aggregation (CA), enhanced use of multi-antenna techniques and support for Relay Nodes (RN).
How does MIMO work in LTE?
One of the tools in the LTE toolbox of radio features is Multiple Input Multiple Output (MIMO) antennas. MIMO enables radio systems to achieve significant performance gains by using multiple antennas at their transmitters and receivers.
What is maximum LTE speed?
Verizon 4G LTE wireless broadband is 10 times faster than 3G — able to handle download speeds between 5 and 12 Mbps (Megabits per second) and upload speeds between 2 and 5 Mbps, with peak download speeds approaching 50 Mbps.
What are 3GPP releases?
3GPP uses a system of parallel “Releases” which provide developers with a stable platform for the implementation of features at a given point and then allow for the addition of new functionality in subsequent Releases.
What is the 3GPP specification?
The term “3GPP specification” covers all GSM (including GPRS and EDGE), W-CDMA (including HSPA), LTE (including LTE-Advanced and LTE-Advanced Pro) and 5G specifications. Revised versions of many of these specifications are produced up to four times a year following the quarterly TSG plenary meetings. The table below leads to information about:
What is release 8 of the LTE specification?
Release 8 was frozen in December 2008 and this has been the basis for the first wave of LTE equipment. LTE specifications are very stable, with the added benefit of enhancements having been introduced in all subsequent 3GPP Releases.
What does the 3GPP 36 series cover?
The 3GPP 36 series of specifications, covers the “Evolved Universal Terrestrial Radio Access (E-UTRA)”. See also – the technologies page on LTE-Advanced, which describes the work beyond LTE Release 8/9.
Why did 3GPP choose a multicarrier approach for multiple access?
To achieve high radio spectral efficiency as well as enable efficient scheduling in both time and frequency domain, a multicarrier approach for multiple access was chosen by 3GPP.
