Classification of microwave link systems
(a suggestion)

According to distance between the points to be connected 

  • Long-haul microwave links (20 to 50 km, in certain cases even more) 
  • Short-haul microwave links (a few hundred metres up to 20 km) 

According to transmission capacity and multiplex process 

  • Up to around 34 Mbit/s (classical PDH) 
  • Up to around 1000 Mbit/s per system (Ethernet or mixed with PDH) 
  • Up to n times 155 Mbit/s (SDH) 
  • Up to 8 Gbit/s for multiband microwave systems

According to frequency band used 

  • 6 to 8 GHz (long-haul microwave links of up to over 50 km, for the highest possible capacity) 
  • 11 to 15 GHz (medium-haul distances of 10 to 20 km) 
  • 18 to 38 GHz (short-haul microwave links between 1 and 10 km) 
  • 40 to 70 GHz (shortest distances of all, up to around 1 km) 
  • above 70 GHz especially for multiband microwave systems

According to equipment technology 

  • Classical indoor equipment with waveguide between equipment and antenna 
  • Splitting equipment (microwave link system with the indoor and outdoor unit separated) 
  • Multiband microwave systems
