TIA-1103-B:2010

Scope of This Document

This standard details definitions, method of measurements and
minimum performance characteristics for Forward Link Only
transmitters. For the purpose of this specification, "transmitter"
shall include any necessary output filter(s) that must be employed
to meet any part of this specification.

This standard shares the purpose of [1], [2] and [3] by ensuring
that a Forward Link Only transmitter can provide service in any
system that meets the compatibility requirements of [1], [2] and
[3].

Compatibility, as used in the connection with this standard and
[1], [2] and [3], is understood to mean that any Forward Link Only
transmitter is able to transmit multicast service information that
can be received by any Forward Link Only device. Test methods are
recommended in this document; however, methods other than those
recommended may suffice for the same purpose.

Revision A of this specification expanded the scope to include
minimum performance test coverage for 7 and 8 MHz channel
bandwidths in the UHF band. Additionally, that revision deleted
unused terms and definitions and removed requirements for I/Q
imbalance and phase noise, since the effects of these impairments
are captured by the MER requirement (see Section 2.1.3.1). Finally,
the MER test procedure was revised to reduce the burden on test
equipment manufacturers, while maintaining essential test
requirements, by changing the minimum number of OFDM symbols over
which measurements are averaged.

Revision B of this specification expands the scope to include
minimum performance test coverage for TIA 1099 Rev A and B
compliant transmitters. New tests for the Signaling Parameter
Channel (SPC) and Positioning Pilot Channel (PPC) characterization
have been added. Existing tests have been updated to reflect
support for

•
2048, 4096 and 8192 point FFT sizes

•
Cyclic prefix lengths (in chips) of ¼, 3/16, 1/8 and 1/16
of the FFT size.

•
Additional pilot patterns specified in
[2].

•
Additional transmit modes specified in
[1].

The Modulation Error Ratio (MER) measurement procedure has been
updated to support new sub-channels (PPC and SPC), pilot patterns
and FFT sizes.

Revision B of this specification also removes any direct
references to band specific and region specific requirements,
instead referring to [4].
