WIRELESS TELECOMMUNICATIONS BUREAU SEEKS COMMENT ON REQUEST BY 4RF

LIMITED FOR WAIVER OF CERTAIN PART 90 RULES TO PERMIT USE OF CERTAIN

EMISSION DESIGNATORS FOR TELEMETRY RADIOS

WT Docket No. 13-188

Comment Date: August 28, 2013

Reply Comment Date: September 12, 2013

By this Public Notice, comment is sought on a request for waiver filed by 4RF Limited (4RF)
concerning use of additional emission designators for Supervisory Control and Data Acquisition
(SCADA) telemetry radios.1 Section 90.207(i) of the Commission's Rules specifies emission designators
A1D, A2D, F1D, or F2D for telemetry operations.2 4RF seeks a waiver of Section 90.207(i) to allow
deployment of telemetry radios using emission designators G1D and D1D. In the alternative, 4RF
requests clarification that these emissions already are permitted for Part 90 telemetry.
4RF Limited designs and manufactures radio equipment for infrastructure application for radio
systems. It has developed narrowband high-efficiency point-to-multipoint SCADA telemetry radio
equipment that complies with the Part 90 emission mask but uses D1D and G1D emissions. 4RF notes
that Section 90.207(i) limits licensees' ability to use the radio system for high-speed telemetry
applications for which it was designed and that are available to users of the system outside the United
States. It states that use of this equipment would facilitate critical infrastructure companies' migration to
IP-enabled technologies for remote monitoring and control applications. As a result, 4RF requests a
blanket waiver of Section 90.207(i) to allow certification, licensing, and use of telemetry radios with G1D
and D1D digital emissions.

Procedural Matters

Interested parties may file comments and reply comments in response to the waiver request on or

Telecommunications Bureau.
2 See 47 C.F.R. 90.207(i). The emission designator is a series of alphanumeric characters that denotes the
necessary bandwidth, type of modulation, nature of the signal modulating the main carrier, and type of information
to be transmitted. See 47 C.F.R. 2.201(b), 2.202(b). D1D is a digital emission that is amplitude- and angle-
modulated, and G1D is a type of phase-modulated digital emission.
