Imagine wireless internet that's actually as fast as a physical cable—no lag, no matter how many devices the signal bounces through.

The Takeaway
Normally, every 'hop' a wireless signal makes to reach its destination adds significant lag because each device must receive a full message before passing it on. This 'RF-Zero-Wire' technique relays signals one symbol at a time, allowing data to flow through a network almost instantly regardless of the number of devices involved.
From the abstract
The latency gap between wired and wireless networks poses a challenge in the adoption of wireless technologies in latency-sensitive scenarios. The gap is especially notable in multi-hop communication typical for industrial sensor networks and robotic swarms. The main reason behind it is that commonly used wireless protocols rely on store-and-forward routing and costly overhead procedures to avoid interference.
