Wired cables are expensive and the more wired network points you have, the more complex the network topology will be.
On the other hand, a wireless network is, overall, a cheaper solution than a wired one with regards to both installing and upgrading the network.
Is Wireless more expensive than wired?
Wireless Internet access is no more expensive than wired access – the service is essentially the same. However, you’ll have to pay extra for the wireless router. As with wired networks, installation costs vary based upon the scope of work.

Is WiFi cheaper than Ethernet?
