Ethernet (1973) is the basis of today's data networks and while it's come a long way, there are still over 4 billion people on the planet that do not have regular access to broadband...the Digital Divide. The root cause is that Ethernet does not work without routers, which use 50% of network just to manage the network (and we pay for twice as much as we use).
Metromedia Broadcasting (formerly Ether2) has the solution that would let 4G and WiFi links operate between devices without cell sites or routers. The result is networks created by users. These secure public mesh networks for data/voice/media services can be enabled with a small communication's chip modification that will limit our carrier dependence, close the Divide, and stop foreign censors from using a "kill switch" on the Net.
