Multi Band Cell

Description of Multi band
§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

§GSM900 4/4/4 Erlang @GoS2% 57.8
§GSM1800 2/2/2 Erlang @GoS2% 24.6
§Total Capacity: 6/6/6 Erlang @GoS2% 104.1



Why Multi Band Cell?
Benefits
§Increased 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 complexity
§Fewer neighbor relations
§Another TS for TCH

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

Benefit
üLess Radio Network congestion
üGreater flexibility in handling Multi Band Cell and Half Rate in the network

Multi Band Cell
Enhancement

Multi Band Cell is enhanced to improve the handover performance in multiband cells. The
locating accuracy for connections using the non-BCCH frequency is enhanced. 
Benefit
üImproved Radio Network performance (handover)
üEasier parameter handling
