Why Telecom Telecommunications is a human need IT can be defined as information transfer across space and time First telecommunications systems used fire, smoke or sound to alert friends about the approach of a foe. Broadband Telecommunications Technologies and Management © 2016, Riaz Esmailzadeh

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. Broadband Telecommunications Technologies and Management © 2016, Riaz Esmailzadeh

Why Did the Persians Build This Road? Your turn! And what were the elements of importance to make it a success. Broadband Telecommunications Technologies and Management © 2016, Riaz Esmailzadeh

Telecommunications and Information Management Telecommunications is an important component of the Information Flow Model. It glues different functions of the model It is instrumental in Information collection and dissemination Efficient telecommunications systems, and innovations create competitive advantages Information Collection Processing and Storage Analysis and Creation Dissemination Broadband Telecommunications Technologies and Management © 2016, Riaz Esmailzadeh

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 Technology Policy Business Broadband Telecommunications Technologies and Management © 2016, Riaz Esmailzadeh

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. Content and Services Layer Connectivity Retail Layer Infrastructure Layer Subscriber / End user Broadband Telecommunications Technologies and Management © 2016, Riaz Esmailzadeh
