Adapt to macro network reality

Distribute capacity in commuting areas:Car park

Entrances Tailgate party Train / subway / metro stations

Often surrounded by arenas or halls

A STADIUM IS MORE THAN A BOWL WITH SEATS & A PLAYING FIELD


Technical Matters: Plan, Design and Dimension the Network

REQUIREMENTS & TECHNICAL FACTORS

Single operator VS Neutral host

Operators / Freq. Bands / Protocols

Surroundings (macro / outdoor)

Validate intermod issues

SISO or MIMO

VENUE & AUDIENCE

Seating capacity

Areas to cover / not to cover: Field? VIP boxes Back office areas

Market share per operator

Usage patterns of operators-users

Equipment rooms

Antenna placement (theory VS reality)

ALL FACTORS INFLUENCING COST & COMPLEXITY OF THE SOLUTION


Providing Capacity Applying RF Design Techniques

User density > colossal capacity

Capacity supplied by >radio sectors

Radio sectors > User data & voice demand

Optimal capacity efficiency > min. interference

Importance of radio planning

Understand usage pattern during eventsUL is often more solicited than DL

STADIUMS REPRESENT IMPORTANT REVENUE GENERATING VENUES OFTEN VISITED BY ROAMERS


Modeling the Environment

UNDERSTANDING THE ARCHITECTURE ... AND THE SURROUNDINGS FOR PROPER 3D MODELING

Coverage from surrounding macrocells

for outdoors and selected indoor areas

Indoor system coverage

needs to be the best server inside the stadium

Handover overlap

for users to handoff from the outside to

the inside of stadium

Design Techniques -

Sectorization

RING STRUCTURE SECTORIZATION WEDGE STRUCTURE SECTORIZATION HYBRID STRUCTURE SECTORIZATION

HOW TO ACHIEVE SECTORS


Coverage from omni

may be excessive, leaking too much power outside of stadium

Reducing power may fix the leakage problem

but some areas may now be not properly covered (bowl)

The use of directional antennas can also be a solution for leakage in this case, providing coverage to the bowl

Designing



In some cases we can also use low power radiating cable in the seating area

Wrap-Up Summary and Q&A

Stadiums are one of the most challenging environments to design for wireless BB

Radio planning attention can enable true WBB signals, ensure QoE

and ROI

Stadiums are high profile venues where operators can generate substantial revenues
