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
12/13/2011iBwave Webinar: Stadiums Page 22
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
12/13/2011iBwave Webinar: Stadiums Page 23
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

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

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

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
