When mobile has been selected successfully the mobile now will start reselection tasks. Perform Cell reselection measurement first Mobile will continuously make measurements on its neighboring cells (as indicated by the BA list) to initiate cell reselection if necessary. At least 5 measurement sample per neighboring cell is needed. A running average of the received … Read more
The development of the simulator that will be implemented can be classified in two phases. The first phase is the development of a simulator, capable for the investigation of the typical handover procedure. The second phase will include the implementation of the LAH algorithm that will consider the location of the user. Simulations that will … Read more
Effect in Cell Coverage Area In coverage limited cells the frequency hopping may increase the cell coverage area because of the frequency diversity gain, but since the BCCH time slot doesn’t hop, the increased coverage area is relevant only for the ongoing calls that have been successfully established and are allocated a hopping TCH. According … Read more
Drive test is simply test of coverage for radiating BTS . from drive test you can imagine BTS coverage boundary and foot print of bad coverage and good coverage.lets understand dt basic. Drive Test Plan Each drive route should be marked on a detailed road map showing the exact route to be driven. These maps … Read more
To protect the logical channels from transmission errors introduced by the radio path, many different coding schemes are used. The diagram below illustrates the coding process for speech, control and data channels; the sequence is very complex. The coding and interleaving schemes depend on the type of logical channel to be encoded. All logical channels … Read more
