Wireless networks abound in many diverse forms. Most notable are the
plain old wireless networks that many of us have in our homes, along
with the general UCAR-maintained network. These radios operate in an
unlicensed part of the radio frequency (RF) spectrum, meaning the
bandwidth has been designated for public consumption with some controls
on the maximum power levels.
My question is in regard to the UCAR NETS group's recent attempt in
controlling these unlicensed bands. Certain parts of NCAR are (or will
be) experimenting with wireless networks in the same unlicensed band
that the UCAR wireless network is located (2.4 GHz).
Does the UCAR NETS group have the ability to halt these
tests/development efforts as they both use the same spectrum as UCAR's
wireless network?
If NETS can halt these tests, are they prepared to forcibly stop all
uses of Bluetooth devices, as they also operate in this band?
Is the UCAR NETS group prepared to issue cease and desist letters to UCAR's many neighbors regarding personal wireless routers?
If the U.S. government has declared chunks of the RF spectrum as free
for consumer use, by what authority does UCAR, or the UCAR NETS group,
dare restrict such devices' operations?

Wireless management at UCAR is guided by the Network Coordination and
Advisory Board policy (see link below). The Network Engineering and
Telecommunications Section (NETS) does not control or halt wireless
usage. NETS, per the policy, asks that wireless usage and testing be
communicated in case of interference and/or wireless performance
issues. NETS has allowed and supported, and in many cases participated
in, testing of other 2.4 GHz band devices in accordance with the policy.
To date, NETS has not seen any evidence of interference between
Bluetooth and 802.11 WLANs. As such, there has been no need to restrict
usage of Bluetooth peripherals.
If there are particular cases of wireless testing or uses that need to be addressed, please contact NETS to discuss.
