Administration Building , Huawei Technologies Co ., Ltd. Bantian, Longgan District, Shenzhen, P.R.China Justification Letter Date (March 9，2018) Dear Sir or Madam, We, Huawei Technologies Co., Ltd. Bantian, Longgang District, Shenzhen, 518129, China hereby to do the original application justification on FCC application: Smart Phone, CLT-L29, FCC ID: QISCLT-L29 as following: CLT-L29 is subscriber equipment in the LTE/ WCDMA/GSM system. The LTE frequency band is Band 1,Band 2,Band 3,Band 4,Band 5, Band 6, Band 7,Band 8, Band 9,Band 12,Band17, Band 18 ,Band 19, Band 20, Band 26, Band 28, Band 32, Band 34,Band 38,Band39, Band 40 and Band 41 . But only Band 2, Band 4, Band 5, Band 7, Band12, Band 17,Band 26, Band 38 and Band 41 test data included in this report. The HSUPA/HSDPA/UMTS frequency band is Band I, Band II, Band IV, Band V, Band VI, Band VIII and Band XIX, But only Band II, Band IV and Band V test data can be used in this report. The GSM/GPRS/EDGE frequency band includes GSM850 and GSM900 and DCS1800 and PCS1900, but only GSM850 and DCS1900 bands test data included in this report. The Mobile Phone implements such functions as RF signal receiving/transmitting, LTE/ WCDMA /GSM protocol processing, voice, video, MMS service, GPS, NFC and WIFI etc. Externally it provides earphone port (to provide voice service) and dual USIM card interfaces. It also provides Bluetooth module to synchronize data between a PC and the phone, or to use the built-in modem of the phone to access the Internet with a PC, or to exchange data with other Bluetooth devices. The mobile phone CLT-L04 ( FCC ID: QISCLT-L04) is a Smart Phone. The differences between CLT- L04 and CLT-L29 are showed in the following table. Model CLT-L04 CLT-L29 FCC Band: FCC Band: B2/B4/ B2/B4/ LTE BAND B5/B7/B12/B17/B26/B B5/B7/B12/B17/B26/B 38/ B41 38/ B41 Licensed MIMO B4/B7 MIMO B3/B7 Frequenc UMTS BAND Band II/IV/V Band II/IV/V y GSM GSM 850/1900 GSM 850/1900 IC the same the same Antenna the same the same NFC the same the same Bluetooth the same the same Unlicense 2.4G Wi-Fi the same the same d IC the same the same Frequenc y 4*4 MIMO B4/B7 4*4MIMO B3/B7 Antenna support RX and TX support RX and TX Ram / Rom the same the same Camera the same the same Hardware PCB the same the same USB Port the same the same
