When it comes to connectivity the PlayStation 3 is very well endowed. For a start, the integrated Bluetooth that’s used to connect the controllers can also be used for other peripherals. That means you can use a standard Bluetooth headset for VoIP functionality and talking to team mates in games, while the latest 1.60 firmware also allows for the use of Bluetooth keyboards and mice. The latter will be particularly useful, since the web browser in the PS3 isn’t bad at all, and since you are more than likely going to have it hooked up to a large, high definition TV, sitting on your sofa and surfing the web is finally a reality.
Of course a web browser is only any good if you’ve got an Internet connection and thankfully the PS3 has this well and truly covered. If you have a router or switch handy, you can make use of the Ethernet port at the rear of the console - I have my PS3, Xbox 360 and Media Center all plugged into a router, which then connects to a HomePlug Ethernet over power adapter, which works a treat.
If you don’t have a switch or a HomePlug setup in your house, then you can make use of the PlayStation 3’s built-in Wi-Fi instead. Assuming you’ve got a wireless network at home, connecting up the PS3 is as simple as pie, and since it supports both WEP and WPA, you shouldn't have any problems with a secure wireless setup either.
