Elements of telecommunication
Telecommunication consists of 3 elements:
1. Source (Transmitter)
2. Medium (Communication Network)
– Transmission System
• Transmission Media
• Modulation
• Multiplexing
– Switching
– Signaling
3. Destination (Receiver)
medium information X information Y
source destination
Why do we need to push the boundaries of telecommunication? Because: • Distance of the two points of telecommunication becomes farther
• Energy consumption for transmission become less abundant
• Everyone wants to be connected anytime anywhere anyway
• Everyone wants better service
In telecommunication research we emphasize on: • How do we represent information?
• How do we sent information?
• How do we restore information?

Common (mistakes) Point of Views
Type of network is based on:
1. Switching Node
2. Link (i.e. metal cable, radio, fiber optic)
A network is best when:
• Faster
• Cheaper
• Effective
• Efficient
communication network
information X information Y
source destination
Faster or Cheaper Network?
• Switching
• Medium
communication network
information X information Y
source destination
• fast but cheap
• choose vendor C Layer 3
• whatever you say lah
• okay, find vendor B Layer 2
• cheap but fast
• use vendor A Layer 1
Effective and Efficient Network?
• Switching
• Medium
communication network
information X information Y
source destination
• effective but efficient
• choose vendor C Layer 3
• whatever you say lah
• okay, find vendor B Layer 2
• efficient but effective
• use vendor A Layer 1
Technology Challenges
1. Optimization, a drawback from layering concept
2. Effective and Efficient, Network Technology or Information Engineering?
3. Standard, a drawback of flexibility
Challenge #1: Optimize
• Each layer depends on the next adjacent layer
• Vertical challenge
• fast enough
• very limited option for interconnection Layer 3
• very fast
• wide options for interconnection Layer 2
• very very fast
• limited interconnection Layer 1
Challenge #2: Effective & Efficient
• 1st phase: Software-defined Network
• 2nd phase: User-defined Network
• 3rd phase (?): Intelligent Network
• Horizontal challenge
communication
network information X information Y
source destination
• business application App Layer
• network services Ctrl Layer
• the network INF layer
Challenge #3: Standard
• Accommodate all parties’ “agenda”
Business Community
Research Community
Development Community
• fast enough
• very limited option for interconnection Layer 3
• very fast
• wide options for interconnection Layer 2
• very very fast
• limited interconnection Layer 1
Conclusion
• There is no such thing as “the best network configuration”
• You decide which technology to be used, but remember, newer is not always better
• Imagine that there’s a network with intelligence capability to identify, classify and choose the best possible network configuration for specific user
