More freedom regarding site location & Option for RAT higher RF Power
Densification - Backhaul becomes more complex

Less available sites/RF power down/new sites need to be close to existing SC sites

Local Ctrlr for real time coordination & scheduling
• Requires careful planning of capacity with subscriber
groups / Interference for the subs not in authorized group
• Macro parity / controller provides plenty capacity even
for the visitors
• Densification is complex & costly (lack of interference
management capabilities)
• Virtually unlimited scaling with controller, advanced
HetNet features & scheduler
• Poor coverage near building walls due to lack of
interference management and limited scheduler
• Coordination / interference management = full indoor
coverage and outdoor vicinity if required
• Limited support for mobility
• Full Mobility support & layer biasing with controller
• Fast deployment
• As fast deployment
• Complex planning and optimization phase
• Limited spectrum planning (full coordination, interf mgt)
• Reduced O&M but no SON support
• Controller O&M offload and full SON parity
