FCC 2.944 Revised as of December 4, 2012
Goto Year:2011 |
§ 2.944 Software defined radios.
(a) Manufacturers must take steps to ensure that only software that has
been approved with a software defined radio can be loaded into the
radio. The software must not allow the user to operate the transmitter
with operating frequencies, output power, modulation types or other
radio frequency parameters outside those that were approved.
Manufacturers may use means including, but not limited to the use of a
private network that allows only authenticated users to download
software, electronic signatures in software or coding in hardware that
is decoded by software to verify that new software can be legally
loaded into a device to meet these requirements and must describe the
methods in their application for equipment authorization.
(b) Any radio in which the software is designed or expected to be
modified by a party other than the manufacturer and would affect the
operating parameters of frequency range, modulation type or maximum
output power (either radiated or conducted), or the circumstances under
which the transmitter operates in accordance with Commission rules,
must comply with the requirements in paragraph (a) of this section and
must be certified as a software defined radio.
(c) Applications for certification of software defined radios must
include a high level operational description or flow diagram of the
software that controls the radio frequency operating parameters.
