Each mobile phone functions at a specific frequency of wireless data transmission. Most mobile providers in Europe and Africa transmit GSM signal(SMS/Voice Calls/GPRS/EDGE) at 900 MHz and some use 1800 MHz in particular regions. EGSM 900 MHz is a mobile network standard for voice. EGSM is the same GSM network but extended for more 10 MHz. Mostly mobile network operators in Europe(Vodafone, Orange, O2, EE etc), Middel East(Mobily, STC, Zain) and Africa(MTN, Vodacom, Etisalat etc) transferred to EGSM 900 MHz.
This dual band GSM repeater can boost cell phone signal at both 900 and 1800 MHz with 500 square meter coverage area.
Some european providers also use 900 MHz frequency for 3G internet connection, 1800 MHz frequency for 4G LTE data tranismission. So if your local mobile provider support 3G 900 or LTE 1800, this booster also will improve both your phone calls and internet connection simultaneously.
