Since there are 5 frequencies in each sector, as per definition of loading factor, there can be only 2 NBCCH carriers equipped on each sector. FER is represented in percentage terms. The MA is a list of hopping frequencies transmitted to a mobile every time it is assigned to a hopping physical channel.

As a result, the decoding and de-interleaving processes can more effectively remove bit errors caused by bursts received whilst on fading frequencies errors will be randomly distributed instead of having long bursts of errors. They transmit dummy burst when BCCH frequency is not in the burst.

Tools for simulation and drive test: It means all the cells in the network use the same frequencies for hopping. Well, first defining MAIO: Home Free calculators Products Tech.

Mobile Allocation Index Offset

But then interference from BCCH 48 must be considered. PH Business Centre 4. Alternatively, for the existing network quality additional capacity can be provided. The problem with this method is that, addition of new site may require frequency replan for the area.

But the BCCH plan for new sites is more difficult. It is very easy to add a ahd in the network. Posted by leopedrini Sunday, February 06, 9: The benefit of selecting these maio is, hopping sequence will start from different frequencies coz of which there ll be a very less chance of facing interference and interference reduction is a important issue to be reduced.

Also there is a plan to reserve these for micro cells.

Mobile Allocation Index Offset – Wikipedia

Please help improve it or discuss these issues on the talk page. This mainly affects stationary or quasi-stationary mobiles. Please help improve the article with a good introductory style.

All the calls suffer from controlled interference but only for short and distant periods of time, not for all the duration of the call. This conclusion is somewhat more complex to see, and is due to feature pseudo randomly from HSN. The HSN is a cell specific parameter.

Mahim Station V1 4. The value of FHI varies between 0 to 3. HSN is set to 0 — This is the case of cyclic hopping.

However there is very less planning involved and so less control over quality problems. Benefits of BBH comparable to SFH can only be obtained by equipping additional hardware in order to include more frequencies in hopping sequence.

HSN allocation to the cells is done in random fashion. Also, please check the max. Due to this there was degradation in call success rate and SD loss factor.

Using very less frequencies for BCCH plan might result in poor quality on BCCH carrier and the advantages of having quality improvement on hopping carriers may be lost. Unsourced material may be challenged and removed.

However it is not possible to plan Mumbai network in 12 considering the terrain.
