Multiple Antenna Precoding: Indoor Communications and EIRP

We analyze massive MIMO and transmitter cooperation for indoor communications. We find that a ratio of twice as many transmitter antennas as mobile users provides most of the massive MIMO benefits and is a good tradeoff between antenna costs and performance. Performance increases with the level of transmitter cooperation. We also analyze the equivalent isotropically radiated power (EIRP) of MIMO arrays. We propose two new EIRP upper bounds which apply to multiple stream transmissions. We find that the massive MIMO advantages are achievable given EIRP constraints.
