Mobile data rate is never at its peak in the history and it won’t be sufficient anytime soon in near future. GPRS, EDGE, 3G, HSDPA, HSPA+, LTE or LTE-Advanced none of these technology will ever will make the data hungry mobile devices happy. Why because it’s a never-ending story. I was watching a football world cup qualifier match two days (more ..)
LTE was developed to work in a wide frequency ranges as well as in many band groups. Many of the LTE frequency bands are used by existing cellular technologies in the other hand others are new as other users are re allocated spectrum elsewhere. This is the main advantage of LTE in terms of usage but when it comes to (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 ..)
