"The past decade has seen the creation of unlicensed device-based telecommunications
services. The most recent of these being the wireless Internet service provider or WISP - that
uses unlicensed equipment to provide Internet service to third parties. These providers use
equipment that was basically designed and authorized as unlicensed Part 15 wireless LAN
equipment. For example, most connectivity with WISPs is through use of Wi-Fi or IEEE
802.11b devices. In addition, unlicensed devices are also being used to provide point-to-point
microwave service. Unlicensed systems, for example, are being used by cellular and PCS
providers for emergency and other backhaul operations to connect cell sites or base stations to
the network."
"Under Part 15, equipment and devices are approved as a "complete" system, i.e., a
transmitter and associated antenna.22 This ensures that the device is not used improperly and
does not cause interference to other services or uses. This approach makes sense for most Part
15 consumer devices. However, in providing service to an area, WISPs often want to select an
antenna that is optimized for local circumstances. Under present Commission rules, they are
limited to antennas sold with the system. This may limit the available technical choices and
result in higher costs due to lack of effective competition for antennas. In addition, both WISPs
and point-to-point microwave system operators have suggested that higher power should be
permitted for unlicensed operation in rural areas. The WISP community has indicated, for example, that it could bring broadband service to more areas if it was allowed higher power in
rural areas." [FCC UDELWG p 14]
