Cellular Transmission Technology

Cellular Transmission Technology
Here are two test sheets identifying a range of cellular transmission technologies for CSA beginners and practitioners. It requires going through the charts to identify the accuracy of the information recorded in them and identify the relevant mobile network operators. It means researching not simply at the mobile network operators' websites, but researching the standards, etc etc etc.

Cellular Transmission Technology

Here are two test sheets identifying a range of cellular transmission technologies for CSA beginners and practitioners. It requires going through the charts to identify the accuracy of the information recorded in them and identify the relevant mobile network operators. It means researching not simply at the mobile network operators' websites, but researching the standards, etc etc etc.

A key aim and objective with CSA is to remember to start out being as thorough as you possibily can and create a very, very long list of all the elements you expect identified and what information you expect to be revealed from the elements and what has actually been revealed from the other side in evidence.

When visiting the discussion various forums discussions can often refer to a technical point but the relevant and specific cellular transmission technology is not identified. The problem this creates is quite often reference to mobile communication 'commands' and 'responses' can be transferred between cellular transmission technology. To assist with these complexities the cellular transmission technology test sheets 1 and 2 identify researched information and you have to find out whether all the information and supporting information is accurate or not. The sense of achievement is guaranteed in the finding out as opposed to confirming to the world look what I know. Have a go and see how much you think you know - what have you got to lose.

Special thanks for all the help from the superb information made available by various sources but not limited to the following organisation GSMA, 3GPP/2, TIA/EIA; Regulatory bodies; the various mobile network operators around the world; Alcatel, Andrew, Anite, Anritsu, Ericsson, Huawei, Jaybeam, Kathrein, Nec, Nokia, Nortel, Siemens, Zapp.

MTEB CSA Fundamentals Training

The MTEB has received an increase in the number of enquiries about fundamental (core) training in Cell Site Analysis.

It could be useful for readers to be reminded in brief, scoping CSA requires applying a wide-ranging methodology incorporated in the investigation and analysis of mobile device activity and mobile communications. That means a CSA participant needs to understand:

- the science operating behind and underpinning CSA
- identifying forensic stepping stones for CSA
- evidence produced for CSA
- reporting on the findings from the conducted CSA.

None of the MTEB subject headers (below) on the course for each of the sections takes precedence over another as all topic elements in the course requires the investigator/examiner/expert to:

- constantly balance and accommodate all of the investigation elements and lines of enquiry
- correlate constants vis-a-vis ambiguities and determine the findings in each of the topics and confirm what the combined findings mean from all topics when aggregrated
- findings should support and cooroborate / deny and disprove the investigation outcome set out in the engaging party's instructions.

(U)ICC/(U)SIM Script Commands and Responses

The discussion under (U)ICC/(U)SIM Script Commands and Responses is one of a number that will appear to assist Diploma students with their course work.

(U)ICC/(U)SIM Script Commands and Responses

(U)ICC/(U)SIM 3F00 7F10 6F4A

3GPP UICC/USIM script selecting Master File, Dedicated File and Elementary File

GSM ICC/SIM script selecting Master File, Dedicated File and Elementary File

Reason for script test : defining an examination procedure to isolate and test a single elementary file; determine the EF's status, file structure, coding etc; conrroborate the ability of the (U)ICC/(U)SIM to action responses from commands sent to card; provide corroborating evidence of commands sent to the card to demonstrate evidential integrity (transparency of practices and procedures); testing the examination card reader is functioning correctly; QA procedures. 

Script examination tool used : USIM Commander - http://www.quantaq.com/usimcommander.htm

Relevant Core Diplomas:-

Aims : MTEB Diploma for Mobile Evidence QA and Evidence Handling - Mobile Telephone Diploma Core CQAE1

Objectives : Device Maintenance and Calibration; Examination Procedure

Aims :  MTEB Diploma for SIM and USIM Technology Examination - Mobile Telephone
Diploma Core CSUT2

Objectives : Your understanding of roles and responsibilities and the importance of
appropriate practices and procedures for SIM and USIM Technology
Examination for acquiring evidence.

Reference Standards :
GSM11.11/3GPP TS51.011/3GPP TS31.102,
GSM11.12,
GSM11.17/3GPP TS51.017/3GPP TS31.120/3GPP TS31.121/3GPP TS31.122,
GSM11.18/3GPP31.101,

EU MTEB Diploma Student Note : Remember to check with ETSI Standards e.g. TS102.221 etc

US MTEB Diploma Student Note : Diploma Students remember to check e.g. C.S0065-0 v1.0, C.S0074-0 v1.0, C.S0074-A v1.0, N.S0009-0 v1.0, S.R0095-0 v1.0 etc

Generically speaking, apart from GSMA and 3GPP, there is also 3GPP2 which also includes ARIB, CCSA, TIA TTA, TTC that all have conditions that can impact/influence results on (U)ICC/(U)SIM.

The discussion under (U)ICC/(U)SIM Script Commands and Responses is one of a number that will appear here to assist Diploma students with their course work.
