Question about networking for modern fruits / arcade machines

Hi All,

I'm hoping that someone can assist me with a quick question about modern fruities and their connections to the Internet.

As I understand it, FOBT / £500 jackpot machines prefer/require Internet connectivity to function properly. I think this is also the case with the latest arcade machines as well and maybe even the CATC (D?) too?

Assuming I am correct, do they require / prefer to have a wired connection or are they all wireless?

Also, is there information about the amount of bandwidth / low latency that they require?

Thanks in advance,

Magz
