Networking over UHF white spaces is fundamentally different
from conventional Wi-Fi along three axes: spatial variation, tem-
poral variation, and fragmentation of the UHF spectrum. Each of
these differences gives rise to new challenges for implementing a
wireless network in this band. We present the design and imple-
mentation of WhiteFi, the first Wi-Fi like system constructed on top
of UHF white spaces. WhiteFi incorporates a new adaptive spec-
trum assignment algorithm to handle spectrum variation and frag-
mentation, and proposes a low overhead protocol to handle tempo-
