    Discovery Time: Next-Gen Dual Band 10 port 800 / 2.5 configurations

    Tested the one of these in Pittsburgh on b26 and b41. It was the first time I ever surpassed 200mbps on b41. Throughput on b26 impressed me as well. The downlink throughput was close to a theoretical maximum for 5x5 MHz wide channel -- 37.4mbps. I think it is safe to assume that the cell was nearly empty. It is TM3-OL SM and 2x2 MIMO, despite having 2 RRUs for 4t4r configuration on 800MHz. If the eNB was capable of 4x4 MIMO, it would be displayed as 4x2 MIMO, since there is no devices that can do 4x4 MIMO on low-band spectrum. I was able to get 202mbps out of b41, which certainly impressed me. P.S.: 800MHz layer seems to be much more optimized than 1900 layer. I could easily get 25-30dB SINR on b26, while it was a struggle to find a spot with SINR above 20dB on b25.

    8 TX Antennas?

    Definitely not. Qualcomm iPhone field test menu is known to report false data when it comes to antenna diversity configuration. I've seen 100+, which would be quite massive MIMO haha
