WiFi walked room to room
What Trang looks for
Signal carried to the back bedroom, because a router in the lounge is not coverage.
Where it happens
Every room. On an example flat: Living room, Bedroom 1, Kitchen, Bathroom, Entry and Bedroom 2.
Why it matters
If you work from home, the internet number is not a detail. It is the whole decision, so it is recorded as a number on the card.
