Another weird note that furthers the disparity seen here: while T - Mobile and Telstra have implemented advanced
Quadrature Amplitude Modulation technologies, both receive the Intel - equipped iPhone 7 which do not support it.
Turning to connectivity, the Note 8 offers Bluetooth 5.0, WiFi ac, 1024QAM for
Quadrature amplitude modulation, and NFC, which combines with MST to offer a multitude of mobile payment options using Samsung Pay.
Today, most wireless communication technologies use lower frequencies (5 GHz or below) with high - order digital modulation schemes, such as
the quadrature amplitude modulation (QAM), to enhance data rates within limited bandwidths available.
