• 4G and 5G in mid-low bands, same coverage area

• Both technologies share the same radio site, connected to the existing Core network

• Example of use cases: eMBB, FWA in wide areas

• 4G in low bands and 5G in high-bands, different coverage areas

• 5G radios may be deployed in new site as needed

• Both technologies are connected to the existing Core network

• Example of use cases: eMBB, FWA in selected areas

• Initial 5G deployments in low bands, benefit from larger coverage areas

• New 5G radio sites, connected to the new 5G Core

• Example of use cases: eMBB, FWA, Industrial IoT

Spectrum Strategy

Spectrum trade-off

”There are major fundamental trade-offs between capacity, coverage, latency, reliability and spectral efficiency in a wireless network. Due to these fundamental limits, if one metric is optimized for improvement, this may result in degradation of another metric.”

— 5G NR co-exists with LTE for many years

— LTE is part of the 5G ecosystem

— Initial deployment of 5G is driven by MBB traffic growth

— NR is needed on high traffic sites to avoid densification costs

— Driven by access to new spectrum/ bandwidth

— A national NR overlay is not needed

— Indoor 5G coverage is important from day one

— New use cases will drive different deployment models and network topologies

— Introduction of 5G will be strongly dependent on available spectrum

— There are trade-offs between capacity, coverage and latency
