Motorola Solutions Asks for TETRA Clarification

Motorola requests clarification as to whether the FCC intended to include the 800 MHz non-NPSPAC public-safety pool channels under the scope of the new rules.

Motorola Solutions requested clarification and reconsideration of the report and order regarding the certification and use of TETRA technology on certain Part 90 LMR frequencies.

In the report, the FCC modified its Part 90 rules to permit TETRA in two bands, the 450 - 470 MHz portion of the UHF band (421 - 512 MHz) and the Business/Industrial Land Transportation 800 MHz band channels (809 - 824/854 - 869 MHz) that are not in the National Public Safety Planning Advisory Committee (NPSPAC) part of the band.

Motorola states that while the report limits the use of TETRA to business/industry and land transportation channels, the adopted rules do not actually impose this limitation. The revised rules apply to all channels within the 809 - 824/854 - 869 MHz band, including non-NPSPAC public-safety channels.

Motorola requests clarification as to whether the FCC intended to include the 800 MHz non-NPSPAC public-safety pool channels under the scope of the new rules.

The vendor also seeks further clarification regarding an amended footnote in Section 90.210 that states equipment designed to operate in the 421 - 512 MHz and 809 - 824/854 - 869 MHz bands may meet the adjacent channel power limits of 90.221 instead of the emission mask requirements of Section 90.201. Motorola asks if this is for all technologies or specific to TETRA.
