DEDICATED CARRIER

SHARED CARRIER

BOTH OFFLOAD TRAFFIC, BUT DEDICATED CARRIER PROVIDES A HIGHER ECONOMIC RETURN

DEDICATED OR SHARED CARRIER – WHICH ONE TO USE?

Metro cellcoverage area

Outer rim of macro cell coverage area

• Large metro cell coverage area• Higher metro cell placement flexibility• Avoids interference with macro cell• Highest economic return, 70% of traffic is

offloaded

• Smaller metro cell coverage areas• Lower metro cell placement flexibility• Higher macro interference• Lower economic return, 30-35% of traffic is

offloaded• Offers effective capacity & coverage for some use

cases and for operators with low spectrum holdings



CAPACITY/THROUGHPUT

PUT CAPACITY

IN ITS PLACE -

CLOSER TO USERS•Backhaul costs

•Community acceptance •Customer premises •Multi-vendor Interop/handoffs

•4x-12x higher capacity than macro cell only deployment•Place where needed•Higher end user speed •Adding metro improves cost•Operational advantages•Ownership – faster, easier to service

SMALL CELLS CAN ADD MASSIVE CAPACITY, BUT EVERY SITUATION IS DIFFERENT!

REDUCED COST

SMALL CELLS PROS/CONS



LTE TARGETED CAPACITY FOR INDOOR STADIUMSREAL WORLD EXAMPLE: IMPROVING QOE AT SPORTING EVENTS

• Challenge – macro network cannot keep up with capacity demands during sporting events. Provide sports fans with the required QoE.

• Solution – provide dedicated capacity to sport fans with Metro Radio placed within the stadium

Three Metro Radios positioned within stadium in roof based on detailed RF plan

2x2MIMO, 10MHz BW (20MHz capable), 10mW DL power (5W capable)

Used shared carrier deployment• Metro Radios greatly improved QoE

68-100% Uplink Improvement (26Mbps) 85% Downlink Improvement (83Mbps)

SIGNIFICANT USER CAPACITY IMPROVEMENTS ACHIEVED IN SHARED CARRIER
