Sirius XM Files Complaint Against Chinese Signal Booster

Sirius XM filed a complaint at the FCC against China’s Shenzhen Tongwei Electronics' wideband signal boosters and California’s MiCOM Labs, which certified the devices. The boosters can operate in the 2300 MHz band, licensed for the terrestrial wireless communications service, in violation of FCC rules, the complaint said. “Testing has shown that these devices produce out-of-band emissions … that cause harmful interference” to satellite digital audio radio service and aeronautical mobile telemetry, the complaint said. The booster models are sold on Amazon under the trade names Beyle, Tonve or Becky, the complaint said. SiriusXM said AT&T, which uses the WCS band, supports the complaint.
