The LTE frequency bands in 3GPP standards are divided into paired bands and unpaired bands. Some of the bands are presently used by other technologies and LTE can coexist with the legacy technologies. In the best case in Europe there is over 600MHz of spectrum available for the mobile operators when including the 800, 900, 1800, 2100 and 2600MHz Frequency (more ..)
The Long-Term Evolution (LTE) is often called “4G”, but many also claim that LTE release 10, also known to as LTE-Advanced, is the true 4G evolution step, with the first release of LTE ( Release 8 ) then being labeled as “3.9G”.
This ongoing race of increasing sequence numbers of mobile system generations is in fact just a matter of labels. What is essential is the actual system capabilities and how they have advanced.
The evolution of 3G systems into 4G is powered by the creation and growth of new services for mobile devices, and is enabled by advancement of the technology available for mobile systems.
Either you are a 3G, LTE or LTE Advanced developer or a tester you will definitely love to have these free study materials and Webcast CDs from Agilent. If you do not know about Agilent, it is one of the biggest wireless test equipments manufacturer in the world.
Agilent is specialized in range of products staring from Oscilloscopes, Protocol Analyzers, Network Analyzers, Bit Error Ratio Test Solutions, EMI/EMC, Phase Noise, Physical Layer Test Systems and many other important test and debugging products.
Non Voice Emergency Service (NOVES ) allows the UE to use other media and communication types other than voice and GTT during an IMS emergency session when the network supports IMS emergency service and the UE also supports other media or communication types.
In case of Emergency session over IMS, Emergency sessions should be prioritized over non-emergency sessions by the system.
In this part the main focus on different use cases where MDT can be applied.
Minimization of Drive Test (MDT) specifies different ways to improve network efficiency by using UE measurement logs. The logs collection in UE can be periodic or event triggered (e.g Radio Link Failures).
To make the MDT process more efficient and provide adequate results, different use cases are defined.
Wireless network is one of the most complex system and to make sure that the Network is working as per the standards and serving the users optimally, the telecom operators perform drive tests. These tests are carried out for different reasons, some times to optimize the network and some other times to debug certain issues in a particular area. The (more ..)
