SpiderRadio is a low cost software driven cognitive radio
prototype that can fulfill this requirement. SpiderRadio can
sense radio spectrum,
detect primary users or interference and switch channels
for dynamic spectrum access. Standard commodity hardware such
as IEEE 802.11a/b/g radio cards, laptops, Soekris boards are used.
With its new MAC protocols and software virtualization, channel
bonding/aggregation/fragmentation, dynamic spectrum access,
ad hoc networking, are some of the
capabilities currently supported.
