RF Planning Strategy•Frequency Planning

– Use automatic frequency planning tools (FAT tool)

– Set different priorities to different clutter types•Avoid interference in high traffic areas.•“Push interference into low priority areas. E.g.

• achieve additional capacity

• maintaining at the same time the quality or performance in the network

• improve quality at a given traffic load distribution

Network Planning


Frequency Planning (Base Band FH)• Base Band Frequency Hopping / DTX / PC

– 7 reuse feasible for TCH

• Use dedicated band– BCCH 15 frequencies -> 15 reuse (ARFCN 59-73)– TCH 21 frequencies -> 21 frequencies (ARFCN 38-

58)

• Total TCH channels per cell = 21/7 = 3• Maximum configuration (aveg.) 4/4/4

– requires good physical network structure

Network Planning


Comparison between BFH and SFH (II)Baseband Frequency Hopping (BFH) Synthesised Frequency Hopping (SFH)

Number of TRXs must be equal to thenumber of assigned frequencies -> lowhopping gains for e.g. 2 TRX cells

More hopping frequencies than installedTRXs may be used -> maximum hoppinggains at moderate cost

Non-hopping frequency plan can be used New frequency plan with tighter re-use shouldbe generated for hopping gains

Typically, re-use is not extremely tight andfrequencies are used at hard blocking limits

Tight (5..9) to extremely tight re-use (1x3,1x1) can be achieved by fractional load onused frequencies

e.g. 40% gain over no FH in same plan e.g. 100% capacity gain with new frequencyplan over no FH in original plan (no PC orDTX yet!)

TPU1 can be used TPU2 must be used

18/8/00

Network Planning


Comparison between BFH and SFH (III)

Baseband Frequency Hopping (BFH) Synthesised Frequency Hopping (SFH)Low insertion losses by filter combiningHigh number of TRXs can be combined

DUCOM insertion losses ok up to 4:1Higher insertion losses from HYCOM

Hopping over BCCH can be used -> hoppinggains for TCHs and SDCCH on TRX0

Hopping over BCCH cannot be usedSDCCH can be allocated on non BCCHTRXs only

Frequency re-planning required for new TRXin a cell

New TRX can be added in a cell withoutfrequency re-planning

Faulty TRX causes cell reconfiguration withloss of all TCHs, since all hopping TCHs areaffected

Faulty TRX only drops calls on that TRX, nocell reconfiguration required

An anchor frequency for the no-FH case mustbe assigned to each TRX.

18/8/00

Network Planning


Frequency Hopping• Advantages

– Interference averaging– frequency diversity– achieve additional capacity with the same quality

in the network (or nearly)• Implementations– BFH

• Advantages:– Ca n use filter combiner– BCCH carrier can hop

• Disadvantage– 1 TRX per freq. In hopping s

equence

– SFH• Advantage:

– can hop over more freq. Than no . of TRX’s (1 /1 or 1 /3 reuse)

• Disadvantages:– BCCHcar r i er can not hop– can not use Fi l t er conbi ner

18/8/00

Network Planning


Concentric Cells

cell splitting: "inner" and "outer" area

- outer channels usable by inner area

one BCCH carrier for both areas

high frequency reuse in inner areas, e.g.

- cluster 3x3 for outer area

- cluster 1x3 for inner area

handover between inner and outer area:

- due to level

- due to distance and level

- due to CIR (Intellig. Underlay Overlay)

one antenna system for both areas

Comparison with Hierarchical Cells

18/8/00

Network Planning


Adaptive Antennas• Principle (I)

– adaptation of "antenna diagram" to reception condition

– increase of antenna gain and cell radius by small beams

– reduction of interference -> reduction of cluster size -> capacity gain• interfere notching• small beams (less interference received in UL / less

interference spread in DL)

18/8/00

Network Planning


Adaptive Antennas• Principle(II)

– Adaptation:• switching between beams• really adaptive electronic beam forming

– BCCH carrier has to be transmitted within the whole cell

– Space Division Multiple Access SDMA:• multiple usage of one physical channel at

same site additional capacity gain

HCS conclusion micro cells as an flexible method for capacity and coverage

enhancement

for capacity purposes mainly applied in hierarchical cell structures

– implementation by intelligent (speed sensitive) handover

– applicable in multi vendor environment (harmonisation of algorithms?)

efficient handling of close proximity scenarios by micro BTS classes

capacity increase by factor 2 - 3 compared to sectorized small cells

economical realisation for various scenarios by using micro BTSs

– low cost for site, installation and operation

Site acquisition problem for normal BTSs expected to escalade!

Limitation and constrain• With high traffic area -> Adjacent

interference have to accept (if not effect in quality criteria)

• To limit coverage area -> some area will be effected in coverage which have to accept for overall network quality

• TOT limitation• Frequency spectrum for high capacity area
