Beyond Massive MIMO

Massive MIMO is no longer a theoretical concept and it is already being adopted in the industry. So we now need to look beyond Massive MIMO or MaMIMO as it is popularly referred to.

60 GHz Millimeter Wave Band – Seems Like a Free Lunch

60GHz Millimeter Wave Band is a band spread between 57GHz and 64GHz. This unlicensed band was first released in the US in 2001 but with limited allowance for transmit power (EIRP of 40dBm). Later on, in 2013, this limit was increased (EIRP of 82dBm) to allow for greater transmit power and larger range.

Massive MIMO and Antenna Correlation

We calculate the degradation in Bit Error Rate (BER) performance due to antenna correlation at the Mobile Station and the Base Station. Exponential Correlation Model is used in the simulation.
