Mesh networks connect a variety of access points and devices across a distributed network, rather than the one-to-one connection that currently exists between your smartphone and that headset that makes you look ridiculous.

This approach dramatically improves the range and reliability of a wireless network, since information can be relayed across several different devices rather than having to stretch between two far-apart devices. And if part of the network goes offline, mesh technology has the capability to route around that outage and still carry out its original mission. Wi-Fi networks have also been getting in on this mesh networking act, which has an additional bonus: mesh networks are much easier to set up than traditional wireless networks.
