sophisticated and costly radio frequency monitoring equipment to locate the interference source.'33 CTIA
echoes this concern noting the difficulty of "identifying the location and operator of the offending
booster."'14 Likewise, the Public Safety Department of St. Lucie County, Florida states that "it is critical
to Public Safety that these signal booster systems be.. . registered with the licensee of the system for
which it will serve" so that signal booster locations are documented in the event the devices malfunction
and cause interference."35
65. While the technical and operational safeguards we propose herein reduce the likelihood that
interference will occur, in the event it does occur, there may be benefits to requiring signal booster
operators to register their devices prior to use. For example, a national signal booster clearinghouse could
hasten interference resolution by providing licensees with a quick resource for identifying nearby signal
boosters and points of contact. Similarly, a clearinghouse could be useful to identify sources of
interference for future network changes. Accordingly, we seek comment on whether signal booster
operators should be required to register their devices with a national clearinghouse prior to operation.
Further, we seek detailed comment on how a clearinghouse could be structured and what information
should be required. Specifically, we seek comment on how a clearinghouse could be administered, by
whom, and whether there are technical or programmatic features that could aid compliance with a
registration requirement, e.g., signal boosters could be equipped with features that would prevent
operation until properly registered. Commenters should also address the costs and benefits of a
registration requirement.
66. While recognizing the potential benefits of signal booster registration, we are mindful of the
burden a registration requirement might create for consumers. We thus seek comment on practical
measures we might adopt to minimize or eliminate consumer burdens. For example, should certain types
of devices be excluded from registration, e.g., consumer versus professionally installed devices?
Likewise, should any registration requirement be limited to fixed signal boosters because their precise
locations are known and registration would allow licensees to quickly identify all fixed boosters in a
particular area in the event interference is observed at a base station? Finally, we query whether, given
the transient nature of the location of mobile signal boosters, registration would be effective in helping to
identify and prevent interference from signal boosters.
D. Signal Boosters for Part 90 Private Land Mobile Radio Service Operations
67. Regarding Part 90 PLMR, non-consumer signal boosters operated by licensees, we propose
revisions to the technical and operational requirements aimed at preventing interference. Specifically, we
propose to:
* Retain the Class A (narrowband) and Class B (wideband) regulatory distinctions and permit
private land mobile fixed (Class A and B) and mobile (Class A only) devices.
* Make clear that Class B devices must be limited to confined areas such as buildings, tunnels,
133 Sprint Nextel Comments at 8. Sprint further explains that locating interference using triangulation techniques is
an inexact process because signals can bounce off some surfaces and be absorbed by others, which creates an
irregular signal footprint. In addition, site access for both the suspected location of the interference and to optimal
observation points can be difficult or impossible to obtain, which further consumes carrier time and resources. Id.

135 Gregory T. Bunting Comments at 1. St. Lucie County has adopted a building code which requires certain types
of buildings to ensure sufficient signal levels for public safety frequencies (806-809 MHz and 851-854 MHz). The
ordinance also outlines a method for determining signal adequacy, requires the use of FCC certified equipment and
requires device registration, including equipment type, location and contact information. Id.5514
