Episode Description

Is 5G LAN coming for Wi-Fi's job? Short answer: no — but in demanding, fast-moving, mission-critical settings, Wi-Fi sweats while 5G LAN thrives. Mia and David unpack what 5G LAN actually is: instead of Ethernet cables, it “uses 5G as the wire,” letting devices on the carrier network wear a “group badge” and talk to each other directly — like neighbors on the same LAN. Then they go five rounds of comparison: coverage and mobility (kilometer-scale, born for movement vs. 30–90 m indoor APs); reliability when dozens of devices crowd one airspace; speed and latency (up to 10 Gbps with sub-10 ms latency vs. Wi-Fi 6’s ~1 Gbps at roughly 20–30 ms); policy-controlled group messaging — unicast, multicast and broadcast; and cost and effort at scale. Real stories bring it home: live-streaming a campus sports day with cameras on the move, AGV fleets crossing factory gates without dropping off the network, port operations synchronized into one “working group,” film-festival crews hopping between temporary venues, and bike-share fleets rebalanced city by city through group multicast — with the geofence switching to temporary-expansion mode for rush hour and a one-shot broadcast when a storm hits. Security is policy-controlled: only authorized roles can send, and cross-city coordination is just a group badge, local UPF handoffs and one consistent rule set. The verdict? Homes, coffee shops and small offices stay on Wi-Fi — cheap, mature, and improving with Wi-Fi 7 — while 5G LAN serves enterprises, campuses and institutions that need wide coverage, low latency and business isolation. They don’t compete; they handshake — and as device ecosystems get smarter and cheaper, 5G LAN slides into cameras, sensors and wearables, with slicing and edge computing widening its lane.
