• Reference years 2018, 2022, 2026, 2030.
Area classification:
• Rural Macro (0–149 inhabitants/km
2 )
• Suburban Macro (150–299 inhabitants/km
2 )
• Urban Macro (300–2499 inhabitants/km
2 )
• Urban Micro (>2500 inhabitants/km
2 ).
Network scenario:
• Existing 2G/3G/4G networks in Germany (statistical data)
• New 2.0 and 3.5 GHz spectrum antenna sites on existing locations with FWA
application primarily
• New 2.0 and 3.5 GHz implementation as Non-Stand-Alone (NSA) with deployment option 3 (3GPP).
Functional units:
• Data rate per area type (Mbps/km
2 )
• Data rate per user type (Mbps/UE/CPE)
• Distinction of data and signalling traffic.
15.4.2 Components—Network Architecture
In this step, the basic (communication) channel model similar to a process flow
model is created. The channel model emulates a real network architecture of a certain
technology generation, its interfaces and network elements. The channel model forms
the central axis or the middle level of the inventory model.
The channel model (network architecture) covers horizontally the essential hardware devices along the network layers starting from radio access network (RAN) with
individual antenna sites (base stations), over an optical transport network (OTN) all
the way to the mobile core network (MCN). The main hardware of these network
layers are aggregated as follows:
Radio Access Network (RAN):
• Antenna Array Unit (AAU)
• Radio Frequency Unit (RFU)
• Base Band Unit (BBU).
Optical Transport Network (OTN)
• Optical Transmission Unit (OTU)
• High Capacity Switch (HCS)
• High Capacity Router (HCR).
