RF Specifications
    Table 2   lists radio frequency (RF) specifications of an RRU3953/RRU3953w.
         NOTE:
       ATBR in the Transmit and Receive Channels column indicates that this RF module has A
        transmit channels and B receive channels.
       CxD W in the Output Power column indicates that this RF module is configured with C
        transmit channels and the maximum output power of each transmit channel is D W.
       EF MSR indicates that E and F data is carried on the same transmit channel of an RF
        module.
       EF non-MSR indicates that E and F data is carried on two different transmit channels of
        an RF module.
       GSM receiver sensitivity is measured, as recommended in 3GPP TS 51.021, at the antenna
        connector on condition that the channel rate reaches 13 kbit/s and the bit error rate
        (BER) is not higher than 2%.
       UMTS receiver sensitivity is measured, as recommended in 3GPP TS 25.104, at the antenna
        connector on condition that the channel rate reaches 12.2 kbit/s and the BER is not
        higher than 0.001.
       LTE FDD receiver sensitivity is measured, as recommended in 3GPP TS 36.104, under a 5
        MHz channel bandwidth based on the FRC A1-3 in Annex A.1 (QPSK, R = 1/3, 25 RBs)
        standard.
       The RRU3953/RRU3953w that works in GSM mode and operates in the 1800 MHz frequency band
        complies with the EN 301 502 V9.2.1 standard. The RRU3953/RRU3953w that works in GSM
        mode and operates in the 1900 MHz frequency band complies with the 3GPP TS 45.005
        V10.2.0 and 3GPP TS 51.021 V10.2.0 standards.
       The RRU3953/RRU3953w that works in UMTS, LTE FDD, or MSR mode and operates in the 1800
        MHz or 2100 MHz frequency band complies with the ETSI EN 301 908 V5.2.1 and 3GPP TS
        37.104 standards. The RRU3953/RRU3953w that works in UMTS, LTE FDD, or MSR mode and
        operates in the 1900 MHz frequency band complies with the 3GPP TS 37.104 V10.4.0 and
        3GPP TS 37.141 V10.4.0 standards.
