Yes, Hence the name PlayStation Portable
PSPs all have built in wifi, and is accessable from any area with a wireless hotspot.
PSPs connect to your wireless router. There's no additional cost for this, but you do of course need wireless internet.
PSPs are not like phones, with their internet packages and data transfer plans. PSPs connect to your wireless router in the same way as a laptop or PC does. So the internet doesn't 'cost' anything when you do this, but you do of course need to actually have wireless internet in the first place, and the PSP can only connect when it is within range.
You don't need anything - two PSPs can create an 'ad hoc' connection with each other, with their own wireless capabilities. There is no need for any kind of add-on or cable, and so those do not exist.
PSPS Pekanbaru was created in 1955.
