LTE came into picture sometime back but still the worldwide deployment did not catch up as expected. Starting from the first quarter of 2012 many network operators already showed their interest to deploy LTE in near future. According to the latest GSA report: 338 operators are investing in LTE in 101 countries 280 operator commitments in 90 countries 58 pre-commitment (more ..)
While going through latest changes in 3GPP I found out that this new feature “Non-Voice Emergency Services”. It is potentially a big and important feature in next generation mobile networks which are mostly IP driven. So what is Non-Voice Emergency Services? Traditionally all the emergency services were over voice (CS) interface, but instead it is better to have a alternative (more ..)
Long-Term Evolution (LTE) allows operators to use new and wider spectrum and complements 3G networks with higher data rates, lower latency and a flat, IP-based architecture. To further improve the broadband user experience in a ubiquitous and cost-effective manner, 3GPP has been working on various aspects of the LTE Advanced standard. Since radio link performance is fast approaching theoretical limits (more ..)
Machine-type communication (MTC) is a form of data communication which involves one or more entities that do not necessarily need human interaction. For MTC communication the following communication scenarios can be identified: MTC Devices communicating with one or more MTC Server Communication scenario with MTC devices communicating with MTC server. MTC server is located in the operator domain. Communication scenario (more ..)
The principles of PLMN selection in [amazon_link id=”012385489X” target=”_blank” ]E-UTRA[/amazon_link] are based on the 3GPP PLMN selection principles. Cell selection is required on transition from EMM_DETACHED to EMM-REGISTERED and from ECM-IDLE or ECM-CONNECTED. Cell selection The UE NAS layer identifies a selected PLMN and equivalent PLMNs The NAS can control the RAT(s) in which the cell selection should be performed, (more ..)
Did you ever struggle to read the 3GPP LTE and LTE Advanced from the standards directly? Some time its very hard to go through many specifications to find out simple things. As the 3GPP specifications are interlinked together and contents tons of information it is always good to follow a book. Because LTE and LTE Advanced is the technology which (more ..)
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 ..)
