Wi-Fi technology utilizes specific bands in the radio frequency spectrum for wireless data transmission. While "2 GHz" is close, the standard bands are 2.4 GHz and 5 GHz. Therefore, 5 GHz is the correct option provided in the list.

• 2.4 GHz Band: Offers greater range and better penetration through solid objects but is more prone to interference from household appliances (like microwaves).

• 5 GHz Band: Provides significantly higher data speeds and less interference, though it has a shorter effective range compared to 2.4 GHz.

We can represent the relationship of these frequencies ($f$) in terms of their standard utilization for Wi-Fi ($W$) as:

$$W_{2.4GHz}\in W$$

$$W_{5GHz}\in W$$
