Cell splitting — purpose?
Increase capacity by subdividing cells.
Cell splitting — power adjustment?
Reduce transmit power to maintain SIR.
Cell splitting — effect on number of cells?
Quadruples when halving cell radius.
Sectoring — purpose?
Reduce interference using directional antennas.
Sectoring — sectors per cell?
Typically 3 (120°) or 6 (60°).
Channel partitioning — within sectors?
Channels are allocated to specific sectors.
Sectoring — interference impact?
Significantly reduces co-channel interference.
Coverage zone approach — key feature?
Zones linked via high-speed links, localized base station radiation.
Microzone — main benefit?
Reduces interference, localizes radiation, increases capacity.
Microcell — typical radius?
Approximately half of original cell radius.
Microcell — power use?
Lower transmit power than larger cells.
Antenna down tilting — purpose?
Limit coverage area and interference.
Interference reduction — method?
Sectoring and localization confine signals, reduce overlap.
Handoff management — intra-cell?
Handled locally via sectoring or micro zones.
Micro zone — channel retention?
Mobiles retain same channel across zones.
Channel reuse — core idea?
Reuse same frequencies in separated cells to increase capacity.
