Components of a Cellular Network.
Mobile Stations
SIM / eSIM
Voice and Data Communication
Mobile Phones
Cells
Frequency Reuse
Handover
Coverage Area
Defines geographical coverage area
Base Stations
Radio Communication
Signal Transmission
Antennas
Connects to Core Network through Backhaul
Core Network
Authentication
Call and Data Routing
Mobility Management
Mobility Management
Manages authentication, routing and mobility
Mobile phone sends and receives data
CELLULAR NETWORK CONCEPT
Cell Structure
Base station at the center (simplified model)
Mobile stations
Hexagonal cell
Adjacent cells
Cell Cluster
Cluster size (N)
Different frequency groups
Group of adjacent cells
Repeating cluster pattern
Cluster pattern repeats
Groups multiple cells
Frequency Reuse
Improves network capacity
Increases spectral efficiency
Reuse frequencies in separated cells
Interference must be controlled
Reuses frequencies in separated cells
Coverage Area
Signal strength
Overlapping coverage
Region served by a cell
Handover between cells
Supports handover between cells
Each cell has a base station
Divides region into cells
Defines signal coverage region
Depends on signal strength
