It is a number that defines the frequency hopping algorithm, and can vary from 0 to 63, ie there are 64 hopping algorithms to be used in GSM. If HSN is greater than zero, then frequencies vary pseudo-randomly.

In our example, the MA List is small - just three frequencies. It is the frequency that TRX uses so get hopping. However, the best way - and always recommended - is to use network planning tools suitable for this purpose, as the AFP, from Optimi, or Ultima Forte, from Scheme. Based on this matrix, along with other algorithms, it allow a better design of parameters based on such critical conditions in traffic load and access.

According to characteristics of each sector, they then provide the final planning, including the possibility of simulations. For example, in two hopping sequences, if we have the same HSN and different MAIO, we guarantee that they never overlap, or in other words, are orthogonal. This conclusion is somewhat more complex to see, and is due to feature pseudo randomly from HSN. Otherwise, just understand that it is why we say that the Frequency Hopping somehow averages the interference across the network.
