UMTS Long Term Evolution, LTE, is the technology of choice for the majority of network operators worldwide for providing mobile
broadband data and high-speed internet access to their subscriber base. Due to the high commitment LTE is the innovation platform
for the wireless industry for the next decade.
This class will provide the basics of this fascinating technology. After attending this course you will have an understanding of
OFDM-principles including SC-FDMA as the transmission scheme of choice for the LTE uplink. Multiple antenna technology (MIMO),
a fundamental part of LTE, will be explained as well as its impact on the design of device and network architecture. We’ll give a quick
introduction into the evolution of this technology including future upgrades of LTE features like multimedia broadcast, location based
services and increasing bandwidth through carrier aggregation.
The second part of the course will provide an overview including practical examples and exercises on how to test a LTE-capable device
while performing standardized RF measurements such as power, signal quality, spectrum and receiver sensitivity. We’ll address how
to automate these measurements in a simple and cost-effective way. We will introduce application based testing by demonstrating
end-to-end (E2E), throughput and application testing using the Rohde & Schwarz R&S®CMW500 Wideband Radio Communication
Tester. Examples of application tests are voice over LTE, VoLTE or Video over LTE.

This tutorial has been designed for audiences with a need to understand the LTE technology basics in very simple terms. This tutorial will give you enough understanding on LTE technology from where you can take yourself at higher level of expertise.
PLNOG 17 - Piotr Gruszczyński - Mobile Fronthaul - ewolucja (a może i rewoluc...PROIDEA
Fronthaul jest rozwijającą się koncepcją, która spowoduje drastyczne wzrost zapotrzebowania na pasmo transmisyjne w sieciach mobilnych, skalą znacznie przewyższajacą to co znamy z wymagań dla Mobile Backhaul. Założenia dla LTE Advanced oraz 5G oraz wirtualizacja kolejnych funkcji już skutkują intensywnymi pracami jak dostarczyć odpowiednie przpustowość do stacji bazowych sieci mobilnych - tych których jeszcze nie ma na rynku.
This presentation is for the people who are interested in mobile release and specifications announced by 3GPP every year, presentation cover all release up to release 12.
Objective is to include the brief insight on 5G network architecture and standard progress, Accumulated it from different paper/journal, vendor’s white paper and different blog.
