Long Term Evolution (LTE) Networks


is 3GPP’s Long Term Evolution (LTE) plan
for current UMTS/HSPA based 3GPP
networks. LTE promises to dramatically
increase data rates with flexibility in channel sizes. Additionally, it
is based on completely All
-
IP flat network architecture to reduc
e
latency, operation costs. This course is designed as technical course
that discusses details of LTE radio interface as well as network
architecture. The network operations of LTE networks such as cell
acquisition, session setup and mobility are explained
. LTE networks
interoperability with 3GPP and non
-
3GPP networks is an important
aspect of LTE deployment. The course covers LTE interworking
with 3GPP and non
-
3GPP networks.
In particular, the course covers
the following important topics

(not exhaustive)
:



Describe major features of next generation wireless

networks



Sketch LTE network architecture and its major components



Sketch Evolved UTRAN network architecture and its major
components



List major features of OFDMA based air interface (E
-
UTRA)



Describe m
ajor features of downlink OFDMA air interface



Describe major features of uplink SC
-
FDMA air interface



Describe major radio functions such as cell acquisition,
radio resource management and handovers



List channels in downlink/uplink and their functions



Des
cribe interworking scenarios with 3GPP networks



Describe interworking scenarios with non
-
3GPP networks
such as 1xEV
-
DO

At the end of the course
, students will be able to define

LTE
network architecture, its radio interface and key functions.


Intended Au
dience

This is a technical course
for LTE

networks. As such, it is suitable
for engineering groups in manufacturers and operators. This
course is suitable for the following audience

This course is suitable for the following audience



R&D groups, network a
rchitects and test groups involved in
design and development and deployment of LTE networks
