CELLULAR SYSTEM
• Data traffic demand in cellular networks is increasing at an exponential rate.
• Link efficiency is approaching its fundamental limits.
• Cell splitting gains are significantly reduced.
• Site acquisition costs can get prohibitively expensive.

SMALL CELLS
• Apart from the capacity increase, small cells could include :
- Better latency
- In-building coverage
- Better cell-edge coverage

NETWORK INTELLIGENCE
• Network intelligence allows mobile operators to manage Wi-Fi access points
• Intel recently conducted a trail that added intelligence to smart cell

NETWORK INTELLIGENCE
• There are two extremely benefits in this way
- mobile operator can cut the amount of traffic through backhaul
- user experience can be largely improved

NETWORK INTELLIGENCE
• Transrating video
- the codec is transrated in a dedicated node at the edge and then decoded right at the small cell.

MOBILITY MANAGEMENT CHALLENGES
• In order to realize the coverage and capacity benefits• Complexity environments• Rapid Varying user equipments• Challenges
• Handover optimization• intercell interference coordination(ICIC)• backhaul provisioning• Self-organization
![Page 19: Heterogeneous network - How do mobile operators exploit different network together to enhance customer satisfaction and reduce operating cost. Yao-Yu Li,](https://reader036.fdocuments.us/reader036/viewer/2022062423/56649e9f5503460f94ba1fdd/html5/thumbnails/19.jpg)
INTERCELL INTERFERENCE COORDINATION (ICIC)
• Unplanned Deployment• operators do not control neither the number nor the location
• CSG(closed subscriber group) Access• cell access is restricted and nonsubscribers are thus not always connected to
the nearest BS
• Power Difference Between Nodes• minimize interference -> connect to strongest cell• Macro cell dead
• Range Expanded Users

SELF-ORGANIZATION
• Cells often deployed without operator supervision• Self-configuration
• Automatically downloaded software
• Self-healing• Failure recovery or execute compensation mechanisms
• Self-optimization• Monitoring the network status and optimize
