Given the need to provide internet connectivity in a hotel, it is worth thinking about whether to run cables throughout the entire hotel or to resort to the simpler wireless solution.
Let us look at the advantages and disadvantages of the two solutions:

LAN Connections
This choice implies the need to provide every room of the hotel with a LAN network socket. These sockets then need to be connected to each other by means of switches, which in turn often need to be connected to each other and to the internet.
The first thing that naturally comes to mind is concern over the practical difficulties. While a hotel is still in the construction phase, it is relatively simple to make provisions for running cable through the hotel in order to connect all the rooms to the various switches. The problem arises if you wish to cable an already existing hotel. Clearly, depending on the dimensions and structure of the hotel, this solution could be practically unfeasible.
Faced with these potential difficulties, LAN connections clearly offer two important advantages :

1) Connection speed: a normal LAN network easily reaches 100 Mbs

2) Security: to connect to the the network you have to use the LAN port, which, being only accessible from inside the hotel, prevents anyone not in the hotel from connecting to the network.

Wireless Connections
Wireless networks in hotels are relatively cheap and simple to install. In practical terms, for a medium-size hotel, just 3-4 Access Points and a switch may be all that is required. All of this would cost around Euro 200-300. In this way, unlike in the previous case, internet access will be immediately available in all the areas of the hotel covered by the WI-FI signal, with practically no need to interfere with the systems already in place in the hotel.
Another advantage of this solution is that it can be used by any type of device fitted with a WI-FI card, whereas handheld computers or mobile phones, etc. cannot be connected to LAN networks, because they do not have LAN ports.
The only real disadvantage of this solution is that the connection speed is noticeably lower than that of a cabled LAN system. To overcome this, the choice and layout of the wireless devices (Access Points) that send out the signal is fundamentally important.
