Spectrum comes in different shapes and sizes (well, different frequencies and bandwidths, to be precise) and a machine system needs spectrum with very particular characteristics.
"We already have a functional link running in the lab, and we are aggressively moving to higher bandwidths, " said Mario Paniccia, director of Intel's Photonics Technology Lab.
When it comes to data transmission and streaming video, what you really want to provide good service is many, many small microcells transmitting service at high bandwidths.
