Stadiums in the Context of an Operator’s Network 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 iBwave Webinar: Stadiums

Technical Matters: Plan, Design and Dimension the Network REQUIREMENTS & TECHNICAL FACTORS
VENUE & AUDIENCE
Single operator VS Neutral host
Seating capacity
Operators / Freq. Bands / Protocols
Areas to cover / not to cover: • Field? • VIP boxes • Back office areas
Surroundings (macro / outdoor) Validate intermod issues
Market share per operator SISO or MIMO Usage patterns of operators-users Equipment rooms
ALL FACTORS INFLUENCING COST & COMPLEXITY OF THE SOLUTION

Best Practices OVERVIEW • Venue • Signals and Sectors •Equipment and Design •Sectorization Methods •Output Plots

Planning IDENTIFY HANDOVER ZONES
Handover overlap – for users to handoff from the outside to the inside of stadium
• Entrances • Transition from concession to main bowl • Signal coming from Macro
Indoor system coverage – needs to be the best server inside the stadium
Coverage from surrounding macrocells – for outdoors and selected indoor areas iBwave Webinar: Stadiums

Planning IDENTIFY KEY AREAS OUTSIDE BOWL
Conference Room North First level
Corporate boxes Second level
Food & Drink First level
Shopping area First level TV commentators’ area Second level
Press and dressing rooms Ground level
Conference Room South First level iBwave Webinar: Stadiums

Planning VALIDATE CAPACITY NEEDS
• Now we can approximate the number of sectors required • Begin to build a sectorization plan inside and outside the bowl

Designing CHOOSE THE RIGHT SOLUTION • Passive • Active •MIMO / SISO • Single / Multi Operator • Select Vendor

Design Techniques - Sectorization
RING STRUCTURE SECTORIZATION

WEDGE STRUCTURE SECTORIZATION

HYBRID STRUCTURE SECTORIZATION
Designing 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)
iBwave Webinar: Stadiums
12/13/2011
Page 32
The use of directional antennas can also be a solution for leakage in this case, providing coverage to the bowl
Designing HOW TO ACHIEVE SECTORS
In some cases we can also use low power radiating cable in the seating area

In Conclusion
Stadiums are high profile venues where operators can generate substantial revenues
Stadiums are one of the most challenging environments to design for wireless BB
