Plenty of Kuala Lumpur offices were fitted for email and shared drives, then asked to host all-day voice. The access points sit in a corridor that made sense for coverage maps and makes less sense for a headset at the far glass room.
A wired desk is not automatically virtuous. We have sat at a cable that shared a tired switch with a backup server and sounded worse than a carefully placed Wi-Fi seat. The cable still wins when the radio is fighting a microwave, a neighbour’s access point on the same channel, or rain on a window-heavy floor.
Monsoon afternoons deserve their own note. Outdoor radio links between buildings, and some last-mile paths, shed more voice after the rain starts. Indoor Wi-Fi may also shift as people close windows and crowd the pantry. If your worst calls are always at 16:00 in November, write that down before anyone blames the app update.
Glass meeting rooms look professional and bounce radio. If the standing pipeline call happens in the glass box, measure there, not at the receptionist’s wired PC. The receptionist may have been telling the truth when they said “it is fine on my phone.”
A practical split we often recommend after an assessment: keep internal huddles on Wi-Fi if they are short, and put the revenue or clinical conversations on the two or three desks that proved clean on a cable. That is a seating plan, not a new philosophy of networking.
Do not run a new cable through a rented floor until the path review says the cable would land on a switch that is actually healthier than the air.
