LTE Advanced - Rel. 12 & Rel. 13 specific Enhancements

flip_lte_advanced_rel12-13_specific_enhancements.pngWe are pleased to introduce our new training course
LTE Advanced - Rel. 12 & Rel. 13 specific Enhancements

This course addresses the needs of technical engineering staff who work on the design, test, integration and validation of LTE-Advanced equipment esp. on the UE-side.

The course has been designed to meet specifically the requirements of chipset verification, integration and testing. The course starts out with a description of the most important trends and visions, in the year 2016, namely the upcoming IoT, the increasing level of network virtualization, the migration towards 5G, the engagement between LTE and WiFi through different options like LTE-U, LAA or LWA and, last but not least, the ever increasing level of scope of carrier aggregation.

Following this chapter, the course reviews the most relevant details of LTE from Rel. 8 up to Rel 11. Note that our trainer will tailor the level of detail and the time spent on this chapter depending on the existing knowledge of the course participants. The following two chapters are dedicated to a detailed description of the updates to LTE-A with Rel 12 and Rel 13. In these chapters, we cover the different levels of carrier aggregation enhancements with Rel 12 and 13, e.g. UL-CA, combined FDD/TDD-CA and the related constraints and practical implementation challenges. In this part of the course we also introduce dual connectivity and its specifics for the UE and for the network side as a new way to do intersite carrier aggregation.

With Rel. 12, there is an exciting new market for 3GPP which is public safety, covered by the ProSe-, D2D- and sidelink- related parts of the specifications. We deal with this fascinating new technology and some of its specifics in this part of the course. Following a detailed analysis of various other enhancements like using 256-QAM modulation, the focus of the course changes to MTC and the IoT. We depict, which approach is taken by 3GPP to suit the needs of the IoT in a 3GPP-environment and point to alternative approaches like SigFox and Lora. The most important topics with respect to 3GPP, dealt with in detail are eDRX, PSM, SIM-less operation and the architecture and radio interface of the NB-IOT. Last but not least, the course focus is on LTE-U, LAA and LWA and depicts the pros and cons as well as the specifics of these three different approaches to combine LTE-A and WiFi.

  • Can HSPA+ ever be considered as a 4G technology?
  • What are the main improvements of LTE-Advanced compared to LTE?
  • How does LTE-Advanced meet or even exceed the ITU 4G requirements?
  • What are the business drivers of SON and where can SON help?

will be answered during this course.

Jul 18, 2011: New Training Course "IMS from A-Z - Reloaded"

flip_ims_a-z.jpgWe proudly announce the availability of our new training course
"IMS from A-Z - Reloaded".

We are pleased to introduce our updated training course "IMS from A-Z - Reloaded". This course addresses the needs of everybody who needs to understand the technology and services of the IMS. New sections focus on voice over LTE functionality utilizing an IMS domain and the reasoning for this architecture according to 3GPP Rel. 8. We will also provide an actual deployment status overview for the different rollouts in Europe and North America. The course concludes with the presentation of a real-life implementation of an IMS.

Questions like:

  • Why is IMS becoming an important complement for mobile operator's LTE deployments?
  • What is the deployment status in Europe and North America in combination with LTE?
  • Where is LTE mobility an issue vs static LTE rollouts (settop boxes / DSL replacement and complement)?
  • What are typical IMS-specific applications and services like "See what I see" and how do they work?
  • What are the functions of the different network nodes inside the IMS?
  • What are the differences between different SIP-server types like proxy, B2BUA and SBC?
  • How do real-life implementations of the IMS look like?

will be answered during this course.

Dec 13, 2010: New training course "From LTE to LTE-Advanced"

flip_lte-advanced.jpg We proudly like to announce our new training course
"From LTE to LTE-Advanced".
This course addresses the needs of technical managers, engineers and technicians who are involved in the design, consideration and development of LTE and other 3GPP cellular standards and in particular the evolution from LTE to LTE Advanced.
The course focuses on both sides, UE/Mobile as well as network. We will discuss in detail the changes and enhancements that will be introduced with LTE-Advanced, such as the increase in throughput, Spectral Efficiency, the relationship with LTE, Carrier Aggregation, Coordinated Multipoint Transmission and the use of Relay Nodes.

Questions like:

  • What are the technologies behind the various specification evolutions from 2G to 4G abd what is the current status of the LTE implementations?
  • How does a voice call setup work with LTE, what are the options and what are the benefits of using VoLGA or IMS?
  • How does Intra- and Inter-Band Carrier Aggregation work to obtain the required system bandwidth?

will be answered during this course.

Oct 19, 2010: New training course "LTE - Interworking with WiFi"

flip_lte_interworking-wifi.jpg We are pleased to introduce our new training course
"LTE - Interworking with WiFi".
This course addresses the needs of managers, engineers and technicians who are involved in the design, consideration and development of interworking implementations between LTE and other 3GPP cellular standards on one hand and WiFi on the other hand. In that respect, the course focuses on both sides, UE/Mobile as well as network.

Questions like:

  • Why is there a need for WiFi to interwork with the EPC of 3GPP Rel. 8 and later and what are the different options for network access?
  • How does a voice call setup work with WiFi, what are the options and what are the benefits of using VoLGA or IMS?
  • How is authentication of the terminal being done in case of roaming through WiFi instead of using LTE access?
  • Which roles may the network and the UE take on when it comes to interworking?
  • How is access permission being handled in case of non trusted non 3GPP access networks?

will be answered during this course.
