3. The Royal Mail
One example of a long distance telecommunications system is the Royal Mail
This road was built by the Persian Empire to connect major centres of the empire which stretched form India to North Africa
The distance between Susa the Imperial capital and Lydia a major provincial centre was 2700 km.
Travelling this distance on foot would take 90 days.
The Royal Mail couriers would cover this distance in 7 days.

6. Technology Business and Policy
Three factors contribute to the success of any product
Technology: how effectively it provides a value to end users
Business: what are the costs of delivering the value
Policy: how national and international regulations govern the value proposition and delivery
These three elements impact on a product success to varying degrees:
At times some of these factors may not play a significant role
Broadband telecommunications is one industry/product that is impacted greatly by all these three factors
An analysis of broadband system must consider Technology, Business and Policy elements

7. Broadband Telecommunications Eco-System
From an end-user point of view, a broadband telecommunications system is a mean for connecting to others and to diverse content
Three business layer may be identified which facilitate this content delivery
An infrastructure layer delivers the physical data. An operator at this layer manages the cables and wireless towers which transmit and receive the data: examples are NBN, Telstra.
One or more companies at the retail Layer manage the customer and content delivery. Examples are Optus, Telstra, Internode.
Many companies produce content of interest to a wide range of subscribers. Examples are Youtube, Facebook, WeChat, Amazon, Google search, etc.

8. Why Broadband Telecommunications
Because it is the infrastructure of the 21st century.
There is a great need for these services, and also for professionals who can provide them
Job growth in the Information and Communication Technology (ICT) field has been the fastest of any industry in the past two decades
