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

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
