Campus infrastructure is being transformed by the rapid worldwide growth of data-intensive science. Scientists must have interactive access to large remote datasets and also to massive amounts of shared rotating storage in on-campus colocation facilities. A critical component of this emerging infrastructure are optical networking clear channels, or lambdas across the campus, state, nation, and globe whose entire bandwidth can be dedicated to a single campus researcher. Simultaneously, enormous innovation is occurring in wireless networking. This presentation will offer examples of applications that are driving the OptIPuter project that require personal lambdas and will also describe a number of Calit2 experiments to determine how best to move from "a gaggle of access points" to a dependable multimode wireless Internet infrastructure on campus.
