What kind of Internet connection do I need to use the OnLive Service?
OnLive works over nearly any wired broadband connection (DSL, cable modem, fiber, or through the LAN at your college or office) with 5Mbps or greater for HD-resolution games. OnLive requires 1.5Mbps for SD-resolution, but initially at launch, OnLive will only offer HD-resolution. Although OnLive technically works over WiFi wireless networks, the reliability of wireless networks can vary greatly, due to interference sources such as microwave ovens, and other wireless networks sharing the spectrum. Initially at launch, OnLive will not support wireless networks.

Don't trust this. Expect the requirements to be at least 30% higher.
