Australia Broadband Assessment

Excepts

Preliminary Assessment Objectives

Provide broadband Internet access to all households and businesses

in Australia

Use a wide range of access technologies including fiber, wireless and

satellite

Determine optimum access technology at a block group level based on

household density and fiber deployment

Estimate satellite bandwidth demand based on realistic broadband

user traffic profiles from Asia and North America

Develop preliminary satellite design and per beam capacity estimates

Note:

O This preliminary study was followed by a more detailed analysis to revisit

access technology for each block code and optimize the beam coverage

3


Target Market

Based on 2006 Census Block Group Data

O 315,000 block groups

O 8.447 Million Households

Block Groups Features

O Small in Size - 90% of block groups are less than 1 mile in size

O Small in Population – 90% of block groups have less than 65

households

Ideal for performing fiber/wireless SATCOM coverage

parametric analysis

O Other demographic data (age, income, education level, etc.) can

also be combined to build more accurate demand model

Fiber/Wireless Coverage

Performed preliminary assessment of fiber coverage using population density

O Country divided into 5 mile (diameter) coverage cells

O Households in each cell determined using block group data

O Fiber coverage determined based as a function of household density

O Cells not optimized to maximize coverage (can be)

O Compared potential fiber deployment to NBN design

Evaluated satellite coverage and capacity requirements for

O Minimum 1000 HH per cell for fiber (87% on Fiber/Wireless)



O Eliminated very isolated cells without nearby fiber

Capacity Analysis

Capacity requirements per household based on 2010 broadband internet usage study

O Evaluated requirements using US and Asia Usage profiles

O Only looked at downstream requirements (driver)

O Broadband usage is dominated (43%) by Real-time entertainment

Typical Monthly Usage

O US: 15 GB (mean), 4 GB (median), 57 GB (Top 20%), 3 hours per day (mean)

O Asia: 35 GB (mean), 15 GB (median), 123 GB (Top 20%), 5 hours per day (mean)

Diurnal Usage of Target market fairly flat

O 30% capacity over mean required for peak busy hour

Capacity per household per month based on average for Top 50% of current broad-band users

O Insures that satellite design can support future demand for the next twenty years

O US: 115 kbps per household per month

O Asia: 226 kbps per household per month
