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

In air interface, BTS, burst, cell site analysis, CSA, GSM, handover, logical channel, physical channel, student, TDMA
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

GSM Normal Burst Power/Time Template
On tháng 6 20, 2014
In 147 bits, 3GPP TS 05.05, call duration, GSM, normal burst, speed of radio signals
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
