Definitions Reference Cell The cell to which you are allocating neighbours
Possible Neighbours The cells that fulfil the requirements to be neighbours
Intra-technology Neighbours The cells defined as neighbours that use the same technology as the reference cell E.g., UMTS-UMTS, GSM-GSM, LTE-LTE
Inter-technology Neighbours The cells defined as neighbours that use a technology other than the reference cell technology E.g., UMTS-GSM, UMTS-LTE, GSM-LTE

Planning Intra-technology Neighbours (6/11) UMTS Technology – Intra-carrier Neighbours Overlapping Criterion % min covered area is defined by the formula : (SA ∩ SB) / SA where : SA is the best server area of cell A. Cell A is the first one in the AS SB is the area where cell B can enter the as of cell A

Planning Intra-technology Neighbours (7/11) UMTS Technology – Inter-carrier Neighbours Overlapping Criterion (carrier saturation) % min covered area is defined by the formula : (SA ∩ SB) / SB where : SA is the best server area (on carrier 1) + handoff area of cell A SB is the best server area of cell B (on carrier 2)
Best Ec/Io for A - Ec/Io margin Confidential – Do not share without prior permission

Planning Intra-technology Neighbours (8/11) UMTS Technology – Inter-carrier Neighbours Overlapping Criterion (out of carrier coverage) % min covered area is defined by the formula : (SA ∩ SB) / SB where : SA is the coverage area of A + Ec/Io margin (and best server on carrier 1) SB is the best server area of cell B (on carrier 2) B best server area
