10. TECHNOLOGY INTRODUCTION
Telco Business & Technology

11. @arydewo
Business Demands to Technology
.
11
Availability
System should be available 24x7x365
Reliability
System performance should be stable during traffic peak and
spike
Fast Time To Market
System should support dynamic market changes, launch
product as soon as possible.
Cost Effective
Budget for spending is no longer luxurious due to the
competition and market changes

Telco User Access Experience

Network Coverage
- Out Of Coverage : too far from
BTS signal reach
- Low Signal : in building, far from
BTS
- Interference : conflicting
frequency
Network Congestion
- Missmatch Demand vs Capacity
1x E1 bandwidth = 2 Mbps
Full HD Access require
1.4 Mbps to 3.4 Mbps
8x E1 max 16 Mbps
Only able to handle 4 to 11 User
concurrently

Telco High Level Architecture Strategy :
Middleware As Key
18
Avoid Spaghetti Environment
It’s delicious when in form of food, but not within IT System
Cost Saving
Changes on every single system is costly in terms of money
and time
Best Practice & Standardization
Follow Industry Best Practice (TMF, TOGAF), Minimize code
fraction thus easier to manage
