Wallcharts are handy reference for mobile design

Racal Instruments has devised a set of wallcharts summarising the UMTS layer 1 technical standards as a reference guide for engineers working in mobile communications design and test.

Racal Instruments has devised a set of wallcharts summarising the UMTS layer 1 technical standards as a reference guide for all engineers working on Layer 1 (and higher layers) in mobile communications design and test.

Developed by Robert Robinson, Racal's system technical authority for 3G platform development, the five sheet summary has proved so useful internally that Racal has decided to make it available industry-wide in the form of a wallchart.

The UMTS layer 1 air interface is described in several 3GPP standards documents.

It is often difficult to visualise how all the elements of these standards fit together, or to remember all the details.

The five summary diagrams provide a detailed reference guide showing the complete end-to-end flow of signal processing.

Notes are included to describe the key steps and other important details.

The diagrams can be used by engineers trying to learn and understand the UMTS standard for the first time, or as aide memoir to those already familiar with it.
