Typical  Network  

•  Transmission  site/system  •  Traffic  source  •  Backhaul  

COMMS  CONNECT  2014  

COMMS  CONNECT  2014  

Tradi;onal  Backhaul  

Low  Speed  •  Telephone  lines  (copper)  •  Data  circuits  (copper/fibre)  •  Wireless  (VHF/UHF)  

High  Speed  •  ADSL  •  Microwave  

COMMS  CONNECT  2014  

Backhaul  Criteria  

•  Speed  (capacity)  •  Distance  •  Security  (physical  and  electronic)  •  Reliability  (MTBF  as  well  as  MTTR)  •  Availability  

COMMS  CONNECT  2014  

NBN  and  Microwave  

•  High  capacity  •  High  reliability  •  Low  cost  •  Availability?  •  Security?  

COMMS  CONNECT  2014  

NBN  Availability  

•  Fibre      20%  of  premises  

•  FTTN/B    46%  of  premises  

•  HFC      28%  of  premises  

•  Fixed  Wireless  5%  of  premises  

•  Satellite    1%  of  premises

COMMS  CONNECT  2014  

NBN  Traffic  Classes  

•  1  -­‐  Real  Time  Traffic,  designed  for  voice,  available  now.  

•  2  –  Interac;ve  Traffic,  designed  for  video,  available  now.  

•  3  –  Transac;onal  Traffic,  designed  for  high  priority  business  traffic,  available  2015.  

•  4  –  Best  Efforts  Traffic,  designed  for  internet,  available  now.

NBN  Access  

COMMS  CONNECT  2014  

NBN  Summary  

•  Most  comms  sites  limited  to  fixed  wireless  and  satellite  

•  Low  cost  •  Low  voice  grade  bandwidth  •  Complex  access  

COMMS  CONNECT  2014  

Microwave  

•  Mature  technology  •  Gbps  capacity  •  User  defined  availability  •  Simple  deployment  •  Low  cost  

COMMS  CONNECT  2014  

Use  NBN  

•  Wide  geographic  dispersion  of  sites  •  Within  NBN  footprint  •  Low  capacity  requirement  •  Mature  IP  design  capability  

COMMS  CONNECT  2014  

Use  Private  Microwave  

•  Regional  coverage  requirement  •  Outside  NBN  footprint  •  High  capacity  requirement  •  Require  simple  network  architecture  •  Internally  managed  and  defined  availability  and  security
