Episode notes
Route/Switch Vet Who Became A Wireless Practitioner
- Gregory moved from 16 years running MSU's campus network (route/switch) into wireless and now does wireless daily.
- He started as a route/switch engineer and used to 'assist the wireless guys' before switching focus.
Why Wi‑Fi Standards Kept Getting Faster
- Wi‑Fi evolution was driven by portable computing and rising bandwidth demands.
- Early 802.11A (5 GHz, 54 Mbps) lost to cheaper 2.4 GHz B chipsets despite being faster, which shaped adoption.
Wider Channels Reduce Contention And Airtime
- More channel bandwidth reduces airtime and contention, letting devices finish transmissions faster.
- Wider channels (20→80→160→320 MHz) mean less time on air per transfer, improving capacity in busy environments.
