Trying to force wireless connectivity out of the Sony PSP has resulted in some interesting
tweaks and hacks by devoted fans of the new handheld
gaming/multimedia platform. In this tradition, I worked at getting the PSP onto the internet using a cellular
connection, which was happily provided by a JunxionBox Wi-Fi to cellular
gateway appliance. The JBox provides a built-in Wi-Fi hotspot where cellular data service is available. As you know,
hotspots are (usually) short range affairs, while
cellular covers wide areas. The JunxionBox essentially "converts" 802.11b Wi-Fi device connections over to a 3G cell
network either for multiple users with Wi-Fi devices or for devices that only support Wi-Fi, like the Sony PSP.
In this experiment, I tried two applications. One was connecting the PSP to play Twisted Metal. The PSP was able to
download stats and server info, but I was unsuccesful in joining and playing an actual multiplayer game. It's unclear
what the problem might have been. Verizon support said they play World of Warcraft over EVDO during breaks in the
lunchroom, so it's unlikely an ISP filtering issue. In any case, I then tried out the Wipeout Pure web browser hack
which was a total success! I connected to the internet and surfed a few different websites.
I am reaching for new ways to interconnect mainstream devices. The Sony PSP is one such device with a semi-locked down
infrastructure, supporting only minor connectivity options. For example, you cannot connect to the PSP using Wi-Fi for
file transfers. And, of course, it does not directly support cellular. By exploring integration options like this, we
can expand the options for a connected highly mobile society.
As a bonus in this video, get a peek at the new "WiFi Toy" wireless research vehicle, a 2005 Toyota 4Runner. (Thanks
for helping me decide, Autoblog!) This vehicle has a lot
in store as I test out new techniques for on- and off-road mobile internet.
UPDATE: I am able to Create a game of Twisted Metal for others to join in. While I couldn't connect to other
games for some reason, I could start my own. Four of us played for about 30 minutes last night with no apparant lag and
ping times of just under 300ms. w00t!
