Google Motorola Anechoic Chamber RF Shield Box SH-120MC-SGA 4G 5G GHz Cell EMI Electromagnetic Interference Signal Test Development Tool Box 480x265x280mm
Made by Will Technology EMI shielding company for Google Motorola. We tested the chamber with a Samsung Galaxy S24 Ultra (not included in purchase), and it blocked the cell tower/data signal very well, making an internet test speed go from 150mbps download/50mbps upload to 0.2 mbps download/0.01mbps upload. Likely still had a little bit of upload speed because the test starts immediately when we pressed the start button and we still had to shut the lid on the box. Box does not do a good job of shielding WiFi signals, those still transmitted through the box reasonably well. Willtek Aeroflex Cobham Viavi
