RRC Measurements Cheat Sheet

RRC Measurements Cheat Sheet (FDD) is a one page help guide. Cheat sheets are useful when debugging an issue or testing a test cases and you just need a quick look instead of going into the specification.

In this document we have recorded all the RRC measurements and the meaning of those events. Please let us know what you think about this.

If you have similar help sheet/cheat sheet which you have created and you want to share please send to us (contact@3glteinfo.com). We will publish those through 3glteinfo.

LTE Resources: Free System Posters


It is always good to have some technology resources. The best way to learn a new technology is to look the overall architecture first, like the end to end communication interfaces, protocols involved, radio interface technology involved, etc. After knowing the overall system architecture one can start going into details of system nodes.

LTE is the latest technology to look into. So these are some of the most useful resources to start learning about LTE. All these posters are free, so you do not have to pay anything.


Free PDF Posters

LTE Poster from Alcatel Lucent

Alcatel Lucent are one of the top network solution provider. The LTE poster from Alcatel Lucent provides some details about bearer architecture, LTE security system, inter-networking of LTE with other 3GPP (UMTS and GSM) and non-3GPP systems. It also provides some basic information about different important nodes in the LTE systems like UE, eNodeB, Serving Gateway(S-GW), Home Subscriber Server (HSS), PDN Gateway (P-GW), etc.

LTE Poster from Nethawk

Nethawk is a simulator and analyzer company. The system poster from nethawk shows all the nodes in the system (LTE, UTRAN, GSM, Femtocell, PSTN network, CoreNetwork). It also gives the names of the protocols on different interfaces.
