According to Urgent Communications, FM Approvals submitted a proposal requesting tohe authority to make changes to the "intrinsic-safety" standards of landmobile radio (LMR), to ensure radios work even under harsh conditions. The proposal was published by the American National Standards Institute (ANSI) on March 25, 2011, and since FM Approvals has received no negative feedback from ANSI, they have initiated the process.
The proposal stems from criticism of the new IS standards, effective January 1, 2012. Voth vendors and Public Safety officials have been outspoken about their opposition of the standards. There are currently no devices certified in the U.S. that are compliant with the new IS standard. Portables that meet the standard would be required to use significantly less output power, which would reduce coverage of LMR systems.
FM Approvals currently has a team working on the changes, and they plan to publish them this August.
