Abstract: An apparatus and method are described for retaining system state of an online application such as a video game. For example, a method according to one embodiment comprises: executing a application on a server in response to user input from a client; transmitting video generated by the application over a network connection from the server to the client; detecting that the network connection has become unusable or impaired; responsively pausing the execution of the application from a current point of execution; and resuming the execution of the application from the current point of execution upon detecting that the network connection has become usable or unimpaired.

Abstract: A system and method are described for distributed antenna wireless communications. For example, a method implemented within a wireless transmission system comprised of a plurality of wireless client devices and a plurality of distributed antennas is described comprising: computing channel state information (CSI) for wireless communication channels between the plurality of base distributed antennas and the wireless client devices; computing precoding weights from the channel state information; precoding data using the precoding weights prior to wireless transmission from the plurality of distributed antennas to the wireless client devices; and wirelessly transmitting the precoded data from the distributed antennas to each of the wireless client devices, wherein the precoding causes radio frequency interference between the plurality of base stations but simultaneously generating a plurality of non-interfering radio frequency user channels between the plurality of distributed antennas and the plurality of wireless client devices.
