The term wireless is a bit strange because it classifies a whole range of modern technology by the lack of a wire. Cordless technologies are getting better all the time, but the reliability and transfer speeds of wires are still superior in many ways. Thankfully, there are plenty of folks working on making wireless equipment that is faster and smaller, pushing the capabilities of wireless transmissions to make mobile devices better and better. Here are just a few notable milestones.
- Transmitting a wireless signal at 2.5 terabits per second isn't anywhere near commonplace yet, but maybe someday wireless spectrum will have almost unlimited capacity. Networking equipment that can handle both orbital angular momentum (OAM) and spin angular momentum (SAM) modulation will have to get out of research labs first. [url]
- Antennas can be the largest component in a wireless device, but a hemispherical antenna design might approach fundamental size limits. Phones might not get any smaller, but there could be more room for batteries.... [url]
- Antennas made of thin films of graphene could allow for terabit per second data transfers over short distances. Graphene is still a tricky material to work with, but as researchers work out how to make useful electronics from graphene, there could be some amazingly small wireless devices in the future. [url]
