3. Introduction

All the fixed line Communication Service Providers (CSPs) in both
developing and developed countries have started their networks form the
urban areas (ex: Main Switching Unit (MSU) in Public Switched
Telephone Network (PSTN)) and move to sub-urban (ex: Remote
Switching Unit (RSU)) and then to rural (ex: Line Extension Unit (LEU)).
For both copper and fiber, this has been the practice for the last 150 years.
Even wireless CSPs have followed the same path first covering the urban,
then sub-urban and then rural.
Two of the most obvious reasons for this:
Demand
Affordability

6. Broadband options
6
When it comes to broadband (BB), now we have 2 options;
wired
wireless
While there are methods to re-arrange an existing copper network by shortening
the copper distance and introducing FTTN/C/B to deliver BB using ADSL2+/VDSL,
the re-arrangement of wireless networks are NOT that feasible.
To cover the green areas, the operators need to deploy new networks;
Copper
Best
Fiber
options
Wireless

8. National Broadband Network (NBN)s

What else governments can do (other than NBN) to make
the citizens lives convenient?
Is FTTH the only NBN option?
Do we need to do it because others are doing?
What governments need to succeed in NBN?
Common sense
Looking for purpose of all they do
Right thinking and attitude
Desire

9. Conclusion
9
Operators/governments, in both developed and
developing countries, need to go back to the
fundamentals and 1st principals in deploying
broadband/Next Generation Access (NGA)
networks.
