Why and How BSIC Planning in GSM

Why and How BSIC Planning in GSM Why BSIC Planning in GSM ? Because when tight frequency planning required or we have very limited frequency to plan then to reduce Mobile confusion about cell id BSIC used to identify cell id after BCCH. lets understand How BSIC Planning in GSM? In addition to the assignment of frequency … Read more

How Interference Diversity in GSM?

Interference is dependent on time, frequency and mobile location. Without frequency hopping, some cell planning margins must be incorporated so that sufficient service quality can still be provided in an interfered situation. By changing frequency on every TDMA frame, a mobile only experiences interference on a particular frequency once in a number of hops. Similarly, … Read more

Comparison between Multi layer Reuse and 1*3 in GSM

Multi-layer reuse pattern is a gradual process for TCH frequency planning. In other words, the reuse is rather loose in TCH1 layer and it is quite close in the last TCH layer .The reason for this pattern is that base band hopping is used in the Multi-layer reuse pattern. When there are rather few frequency … Read more

Frequency Planning Steps for GSM

Frequency Planning is possible by manually or automatic.At initial stage of new RF Network automatic frequency planned and then after for optimization based on KPI manual frequency planing done. Manual Frequency Planing Steps The steps to be followed in manual frequency planning are: Calculating the frequency reuse distance theoretically. Determining the cell repeat pattern Planning … Read more
