  22. 22. Network PlanningFrequency Planning (BaseBand 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 = 3RF Strategy 18/8/00•

  26. 26. Network Planning Comparison between BFH and SFH (II)Baseband Frequency Hopping (BFH) Synthesised Frequency Hopping (SFH)Number of TRXs must be equal to the More hopping frequencies than installednumber of assigned frequencies -> low TRXs may be used -> maximum hoppinghopping gains for e.g. 2 TRX cells gains at moderate costNon-hopping frequency plan can be used New frequency plan with tighter re-use should be generated for hopping gainsTypically, re-use is not extremely tight and Tight (5..9) to extremely tight re-use (1x3,frequencies are used at hard blocking limits 1x1) can be achieved by fractional load on used frequenciese.g. 40% gain over no FH in same plan e.g. 100% capacity gain with new frequency plan over no FH in original plan (no PC or DTX yet!)TPU1 can be used TPU2 must be used RF Strategy 18/8/00
  27. 27. Network Planning Comparison between BFH and SFH (III)Baseband Frequency Hopping (BFH) Synthesised Frequency Hopping (SFH)Low insertion losses by filter combining DUCOM insertion losses ok up to 4:1High number of TRXs can be combined Higher insertion losses from HYCOMHopping over BCCH can be used -> hopping Hopping over BCCH cannot be usedgains for TCHs and SDCCH on TRX0 SDCCH can be allocated on non BCCH TRXs onlyFrequency re-planning required for new TRX New TRX can be added in a cell withoutin a cell frequency re-planningFaulty TRX causes cell reconfiguration with Faulty TRX only drops calls on that TRX, noloss of all TCHs, since all hopping TCHs are cell reconfiguration requiredaffected An anchor frequency for the no-FH case must be assigned to each TRX. RF Strategy 18/8/00
  28. 28. Network PlanningFrequency Hopping• Advantages – Interference averaging – frequency diversity – achieve additional capacity with the same quality in the network (or nearly)• Implementations – SFH – BFH • Advantage: • Advantages: – can hop over more freq. Than no. of TRX’s (1/1 or 1/3 reuse) – Ca n use filter • Disadvantages: combiner – BCCH carrier can not hop – can not use Filter conbiner – BCCH carrier can hop • Disadvantage – 1 TRX per freq.

  29. 29. Network PlanningConcentric Cells PrincipleNetwork Layout cell splitting: "inner" and "outer" area - outer channels usable by inner area high frequency reuse in inner areas, e.g. - cluster 3x3 for outer area - cluster 1x3 for inner area one BCCH carrier for both areas one antenna system for both areas handover between inner and outer area: - due to level - due to distance and level - due to CIR (Intellig. Underlay Overlay)RF Strategy 18/8/00

  31. 31. Network PlanningAdaptive 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)RF Strategy 18/8/00
  32. 32. Network PlanningAdaptive 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 gainRF Strategy 18/8/00
