comes with preset support for many common optical modulation formats, including QPSK, 16QAM, and 64QAM.
La BS con la que se realizo el estudio es una antena sectorial con ganancia de 14 dBi y potencia de 36 dBm tanto para la BS como para las SS con un nivel de senal a ruido por debajo de los 30 dBm permitiendo asi una modulacion hasta de 64QAM para cada conexion; cada nodo es conectado a traves de una conexion Ethernet al equipo WiMAX.
Both of the two techniques supports different modulations, such as QPSK, 16QAM, and 64QAM.
The lower order modulation formats, like QPSK, do not transmit data as fast as the higher modulation formats, such as 64QAM, but they can be received when signal strengths are lower.

By adopting 64QAM (Quadrature Amplitude Modulation) and MIMO (Multiple Input Multiple Output) technology with 2T2R (two transmitters and two receivers) capabilities, Huawei's latest LTE eNodeB is able to maximize the use of the ultra-wide bandwidth of LTE networks.
