is 15-20 dBm. LTE sensitivity requirement for the medium range base station is -96.5 dBm for the Reference channel A1-3 which gives approximately 2 Mbps. The typical sensitivity is better - in the existing macro base stations even 10 dB better. Wi-Fi sensitivity is assumed to be -93 dBm for the lowest modulation and coding scheme of MCSO. The maximum uplink path loss is then 119.5-129.5 dB for LTE and 108-113 dB for Wi-Fi. The LAA downlink path is 129 dB with 30 dBm base station power (the same is assumed for Wi-Fi) and -9 dBm UE sensitivity. The sensitivity requirement is taken from 3GPP minimum requirement for Band 1 with 20 MHz bandwidth. We further assume that the typical UE sensitivity is 5 dB better than 3GPP requirement. The Wi-Fi path loss is estimated at 123 dB.

MCSO providing 6 Mbps with 20 MHz. budget differences between LAA and Wi-Fi comes from the radio layer optimization including channel coding (Turbo coding), fast retransmissions and soft combining, fast link adaptation, optimized modulation for RF power amplifier (SC-FDMA) and well-defined RF requirements in 3GPP. Figure 10.14 shows the relative cell ranges of Wi-Fi and LAA for outdoor small cell. We assume that Wi-Fi with 108 dB path loss at 5 GHz band can provide 50 meter cell range. The other values are then estimated based on the ass
