BigBand: GHz-Wide Sensing and Decoding on Commodity Radios

Hassanieh, Haitham; Shi, Lixin; Abari, Omid; Hamed, Ezzeldine; Katabi, Dina (2013-05-22)

The goal of this paper is to make sensing and decoding GHz of spectrum simple, cheap, and low power. Our thesis is simple: if we can build a technology that captures GHz of spectrum using commodity Wi-Fi radios, it will ...
One Clock to Rule Them All: A Primitive for Distributed Wireless Protocols at the Physical Layer

Abari, Omid; Rahul, Hariharan; Katabi, Dina (2014-04-27)

Implementing distributed wireless protocols at the physical layer today is challenging because different nodes have different clocks, each of which has slightly different frequencies. This causes the nodes to have frequency ...
