1
Will 5G Wireless Overtake Fiber to the Premises?
Jim Selby - President
2
What types of 5G today Outlined in the ITU draft:
A peak data rate of 20 Gbps downlink and 10 Gbps uplink A peak spectral efficiency of bps/Hz downlink and 15 bps/Hz uplink A user experienced data rate of 100 Mbps downlink and 50 Mbps uplink (in a Dense Urban test environment)
3
What is 5G fixed wireless?
Millimeter Wave Wireless (mmWave) Technology mmWave consists of GHz 60 GHz V-Band is unlicensed Officially named IMT-2020, currently in standardization process by the International Telecommunications Union (ITU) Final standard definition expected by 2020
4
Current 5G Specifications
Outlined in the ITU draft: A peak data rate of 20 Gbps downlink and 10 Gbps uplink A peak spectral efficiency of bps/Hz downlink and 15 bps/Hz uplink A user experienced data rate of 100 Mbps downlink and 50 Mbps uplink (in a Dense Urban test environment)
5
Functionality Up to 120° functional angle on mmWave antennas
Flexible - easily reconfigurable to respond to environment or needs Point to MultiPoint capable O² absorption reduces range, but also reduces interference Line-of-Sight disruptable, but no need to bury lines
6
Common Use Cases Areas where fiber deployment is cost-prohibitive, such as Low Density (rural) or Very High Density (large city) Wireless to the Premises, last mile deployment Wireless Redundant Backhauls Smart Cities
7
Risks of using 5G FWA Reliant on line of sight
“Wireless” vs “Hardwired” perception Incapable of transmitting analog or DAS signals Upgrading is more expensive than transceivers Shorter effective life span IMT-2020 is still being defined, “5G” may not mean the same thing to different parties
8
Reliability Line of sight disruption
O₂ and H₂O absorption, affected by weather When line of sight is maintained, performance is stellar Capable of meeting current consumers needs
9
Average internet connection speed in the US
Sustainability Cost effectiveness - estimated savings of 40% for last-mile connectivity vs FTTP Not susceptible to breakage, e.g. tree limbs, trenching No need for locating services Increased replacement or upgrade costs Future demand may exceed capabilities Average internet connection speed in the US
