What a good answer should say
- Twisted pair
Explanation
Why this works
Both twisted pair and wireless radio can cover a few hundred metres, but twisted pair uses inexpensive copper cabling and connectors. The key difference is that twisted pair is a wired medium with predictable performance, whereas wireless is subject to interference and requires additional infrastructure.
For a cost‑effective office network, twisted pair is the appropriate choice.
