Mobile Allocation Index Offset

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. Mwio Hopping plan differs from the conventional fixed frequency plan.

The problem with this scheme is in peak hours there may be more hits.

Thane Stn V1 6. Further details regarding FHI planning are discussed later in the document. Three hopping groups are used in 3 sites, one per site. This is very useful to identify the change in any of the areas and the cause. More on the FH due to a new tutorial. Tools for simulation and drive test: BCCH carrier is very important for logging on to the network or staying in the network.

What is HSN and MAIO in GSM? – telecomHall

However it is not possible to plan Mumbai network in 12 considering the terrain. Plan for 1 x 1 plan.

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. If 15 frequencies are to be used for hopping, then every cell will have all 15 frequencies in the MA list.

Also it was observed that for files of size KB, the data transmission takes at a speed of 8KB to 8. Addition of Site e. No problems found 3. Frequency Hopping is able to take the advantage due to frequency selective nature of fading to decrease the number of errors and at the same time they are temporally spread.

It was decided to go for 1 x 1 after 1 x 3 implementation. This page was last edited on 14 Aprilat The results are dependent on the traffic loading carried during the drive and also on the quality of BCCH or the hopping carriers.

Summary of problems observed after 1 x 3 implementation: It is possible to assign 64 different HSNs. The goal here is not to teach HSN and MAIO planning, since this task involves many possible configurations and scenarios, which would escape the scope of our tutorial.

HSN is set to 0 — This is the case i cyclic hopping.

Never the data is transferred at KB. If there is degradation in quality the downlink or uplink power increases. Call success rate will depend on the cleanliness of BCCH carriers. The plan depends upon the type of Frequency Hopping system used. JP Road V2 – both 4.

However quality of hopping carriers improves than before.

This reduction may get compensated due to improvement in quality of hopping carriers improvement in TCH assignment success rate.
