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.
Only recently has some spectrum that fits these characteristics been found, and work is still under way in the UK to make it available for commercial use.
Electronics is different, though, because every form of electromagnetic energy is manifested on a single spectrum and shares certain fundamental characteristics.
To our knowledge, no published information is available on how their characteristics may differ from the general population of children with autistic spectrum disorders.
As I mentioned antenna design engineers have gotten very good at what they do but since each antenna must be electrically matched to the transmitter and receivers, it has to have certain characteristics that differ from the antenna for a different portion of the spectrum.
Arraycomm's approach allows the base station to constantly adapt the characteristics of the signal as the user moves around, keeping it focused, increasing spectrum efficiency and reducing interference from all the other signals permeating the air.
