American Tower is the largest telecom infrastructure company in the US, with over 150,000 wireless communication sites globally. As data usage and demand for capacity increases, network densification through small cells and new infrastructure solutions will be required. American Tower is innovating to address this need through strategies like developing new small cell and tower sites hidden in urban locations, fiber and wireless connectivity options, in-building solutions, and supporting the transition to 5G networks and technologies like ATSC 3.0 broadcast broadband.

5. ATC Innovation
„ Change is now constant – not linear, more disruptive
„ Explosion in Data è Spectrum bottlenecks è Densification
„ Spectrum is real estate – it’s finite – lots of it, but never enough
when or where you need it
„ It’s all about capacity and spectral efficiency now
„ Macro Towers MORE relevant in network design – the
exoskeleton for 4G and 5G is the macro tower
„ Distinct network “canopies” will be built
„ Hiding in Plain Site – new urban solutions
„ Mobile “Anyhaul” – fiber and alternatives
„ In-building
„ 5G Momentum
„ New Broadcast technology: ATSC 3.0

• New spectrum – new business model
• 150 GHz of spectrum - Spectrum sharing model with managed
allocation to prevent interference
• LTE networks deploy like Wi-Fi networks do today
• LTE capability at cost of Wi-Fi
• Unique ecosystem –Tech leaders Google, MNO’s, MSO’s, Ericsson,
Cisco, Ruckus, Nokia, Federated Wireless
• Trials this year
• Value proposition lies in the management of core network functions; e.g.
a neutral host model
• The Other 98% of buildings / venues
