Multi Band Cell in GSM

Multi Band Cell makes it possible to mix transceivers from different frequency bands in one cell.BCCH only have to be reserved in one of the frequency bands.For the radio network this will enable both increased capacity and savings in operation and maintenance cost.
Capacity increase

BenefitsIncreased radio network capacity (Trunking efficiency).Improved radio network quality, because fewer neighbors-cells means that terminals will find the best handover candidate more often.Reduced cost for radio network handling, as there will be significantly fewer cells.

Higher spectrum utilisation
   –Freeing BCCH frequencies   –By pushing traffic to OL subcell

Reduced number of physical cells   –Transparent frequency band   –Less network complexityFewer neighbor relations & Another TS for TCH

Dynamic Overlaid/Underlaid Subcell 

EnhancementDynamic Overlaid/Underlaid Subcell is enhanced so that subcell load distribution is possible to initiate also in the overlaid subcell.

Benefit>Less Radio Network congestion>Greater flexibility in handling Multi Band Cell and Half Rate in the network




Multi Band Cell

EnhancementMulti Band Cell is enhanced to improve the handover performance in multiband cells. Thelocating accuracy for connections using the non-BCCH frequency is enhanced. BenefitImproved Radio Network performance (handover)Easier parameter handling
