Final answer:
The size of the building, the number of solid interior walls, and the presence of microwave ovens affect the number of access points needed for wireless connectivity.
Step-by-step explanation:
The three factors that affect the number of access points needed to provide wireless connectivity to a wired ethernet network of a building are:
- Size of the building: Larger buildings may require multiple access points to ensure adequate coverage and signal strength throughout the premises.
- Number of solid interior walls: Solid walls can obstruct the wireless signal, requiring additional access points to overcome the barriers.
- Presence of microwave ovens: Microwave ovens operate on similar frequencies as WiFi, which can cause interference and reduce the range and performance of wireless networks. If there are many microwave ovens in several offices, additional access points may be needed to compensate for the interference.
