Insulated windows

UV protection

Energy efficiency

Modern buildings provide higher

energy efficiency but also worse

indoor connectivity since cellular

signals are impeded

Weak signals

Blocked signals

Poor indoor performance

barrier to reach indoor users Driving small cells needs

Traditional building walls impose high

penetration losses to radio signal that

affect indoor user experience

For Gates area mostly will be covered by RDS due to some area have more partition

For Arc Area mostly will be covered by mRRUS cause open area to reduce Spot number (save OPEX)
