Tech Updates

Cell typesGSM reports, as far back as 20 years ago, distinguished three kinds of cells as the growth in GSM installations massively increased following popularity as a preferred digital cellular network: large cells, small (mini) cells and micro cells. The main difference between these kind of cells lay in the cell range, the antenna installation site, and the propagation model applying to each

Students learning Cell Site Analysis (CSA) are eventually faced with having to communicate to other non-technical people various technical aspects of the transmission technology that is the subject of the student's work. Sometimes this means finding visual ways to present a technical statement. Below are some visual suggestions that may help.GSM mobile telephones transmit and receive information

The image (below) is of the power/time template to illustrate a GSM Normal Burst (GSM05.01/05.02). A single burst when transmitted may contain up to 114-bits of useful speech data. Given the speed at which GSM radio signals traverse the ether calculated in micro-seconds to be received at a destination handset and processed by that handset in milli-seconds and converted into audible speech within

Joe Hoy from Forensic Analytics joins us this month at Cell Site Analysis blog to outline the purpose and content for his forthcoming book regarding  RFPS (Radio Frequency Propagation Survey).What is your background, Joe?"I am a telecoms engineer and trainer with 27 years of industry experience. For the last 17 years I have concentrated on telecoms training, specialising in cellular technologies

A fundamental and vital goal of any mobile communication network is to maintain communications between the network and the mobile station (MS), whether the MS is dwelling in an area or on the move. To assist the aims and objectives GSM is commonly known to use 'Handover' for which there is a specific GSM standard TS03.09 [cf W-CDMA see 3GPP TS23.009].The assumption being made for these cause

GPRS CSA http://cellsiteanalysis.blogspot.co.uk/2013/11/gprs-csa.html

There are often forum discussions about GPRS (general packet radio switching) and how to conduct CSA (cell site analysis). Given that GPRS is expected to form a basic data service across GSM/WCDMA/LTE it is always worth starting at the beginning with GSM/GPRS as GPRS has numerous influences on GSM that have evolved for today's mobile networks.As the old adage goes "time and tide wait for no man"

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
