USA, LMCC seeks more clarification on harmfull interference on data burst using TETRA

The Land Mobile Communications Council (LMCC), a nonprofit association of organizations that represent the wireless communications interests of public safety, critical infrastructure, business, industrial, transportation, private and common carriers, and manufacturers of wireless communications equipment, submitted reply comments to Icom America’s request for clarification of Section 90.187(b) of the FCC’s rules as to whether a data burst constitutes harmful interference in the amendment of Part 90 of the FCC rules to permit TETRA technology.
Both Motorola Solutions and the Telecommunications Industry Association (TIA), filed comments in the proceeding.
The LMCC reply comments are in reference to the TIA comments, which supported FCC issuance of a blanket clarification that the 250-millisecond data burst described by Icom doesn’t constitute harmful interference in the 150 - 512 MHz bands. However, TIA limited the scope of the clarification it endorsed by urging that it not apply to operations on public-safety pool frequencies without further input from the public-safety community and manufacturers.
In the LMCC filing, LMCC states that it “knows of no technical basis for distinguishing between operations on public-safety versus industrial/business pool frequencies with regard to potential interference from such data bursts.”
