Today the FCC granted a waiver to Multispectral Solutions, Inc. (MSSI), allowing the company to use additional peak power for tracking devices under Section 15.250, which authorizes ultra-wideband-like operation at 5925-7250 MHz.
This band is heavily used by fixed microwave operators. MSSI and the Fixed Wireless Communications Coalition successfully negotiated a set of conditions to protect microwave users, which the FCC wrote into the waiver grant.
