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
Antenna Configuration
