5G: what you DON'T know!! (3 things)

About this video

In a Verizon-sponsored video built around an interview with Heidi Hemmer, Verizon’s VP of Network Engineering, NetworkChuck explains ‘3 things’ about 5G, plus a bonus fourth. First, a new 5G phone does little new yet: performance depends on band — low-band travels far at roughly 4G-like speeds, mid-band he puts at roughly 100-900 Mbps, and high-band/millimeter-wave (Verizon’s Ultra Wideband) requires being very close to small cells but he cites roughly 1-10 Gbps, with phones/carriers auto-selecting the best available network. Second, not all 5G is equal because traffic beyond the tower traverses the carrier core: at the time of filming (he notes November 2020) Verizon 5G still anchored to the 4G core, with a planned standalone 5G core built on software-defined networking, containerized/web-scale architecture, AI/machine learning and mobile edge computing to deliver low latency and network slicing. Third, he predicts 5G could replace Wi-Fi in public places, homes and businesses — citing in-building units and a private ’network in a box’ — arguing licensed, carrier-controlled spectrum and security are advantages over public Wi-Fi. The bonus point is that 5G is not mainly about phones: use cases discussed include AR/VR and network slicing in factories to guarantee capacity for safety-critical equipment like forklifts.

Key takeaways

• 5G speed depends on band: low-band = long range/slower, mid-band = faster, high-band millimeter-wave = fastest but very short range
• The carrier core behind the tower matters as much as the radio link — a 4G core limits what 5G can deliver
• Verizon’s planned standalone core, per the interview, uses SDN, containers/web-scale design, AI and edge computing
• Creator predicts 5G could replace Wi-Fi in public, home and enterprise settings, citing security and licensed spectrum
• Long-term pitch is industrial: network slicing can reserve guaranteed capacity for critical uses like factory equipment
