Voice + 4G Phone Booster Lance 800 V4G-H 2-Band 1800/900Mhz Strict design and hand-cooled metal of Voice + 4G Phone Booster; secondly is automatic and manual control of signal amplification; thirdly the really optimal price and excellent quality - this is what distinguishes this amplifier. Lance Voice + 4G Phone Booster is a premium line device from the manufacturer Rangeful. The Lance 800 V4G-H cellular repeater is a device that amplifies the 4G 1800Mhz internet signal and GSM calls. This Voice + 4G Phone Booster is a great solution for premises and areas where mobile signal reception is unstable, or, for example, internet speed is insufficient due to low signal level. The Voice + 4G Phone Booster makes communication available in any location, even if the operator's stations are up to 15-20 km away. The mobile signal amplifier is used to amplify three types of mobile signals on two frequencies: 900 MHz - EGSM/GSM-900 (2G), UMTS900 (3G) 1800 MHz - LTE1800 (4G) Unfortunately, although UMTS900 (3G) is supported, it is a rarely used standard. Therefore, we offer this model as an amplifier for voice calls and 4G Internet. Output Power This mobile amplifier (also called phone amplifier or GSM booster) has an output power of 23 dB. With this power, you can amplify the signal on an area of up to 800 m2. However, if this power is not enough, you can choose a mobile amplifier with more power here . Antenna Isolation Detection technology When you first turn on the repeater, it automatically detects the oscillation between the outdoor and indoor antennas. The oscillation means that the outdoor and indoor antennas are too close to each other. The presence of automatic gain control allows the repeater to tune optimally under the given conditions. Voice + 4G Phone Booster Application This Mobile Booster has the necessary functionality and an optimal price, making it the best choice, especially for offices, homes, basements, and garages. Important 1. each internal antenna has a maximum range of 50 to 300 m², but it depends, for example, on the floor plan, the material of the walls, etc. 2. the splitter and the additional coaxial cable are necessary to install a second internal antenna. 3. we recommend the use of an internal antenna in each room. This will allow you to get the best performance from your GSM amplifier system. However, it is not mandatory. How a repeater works? 1. The weak HF signal is received from the operator's base station by an outdoor antenna. 2. The signal is sent from the outdoor antenna to the repeater via a coaxial cable. 3. The repeater amplifies the signal. 4. Then another coaxial cable is used to transmit the amplified signal to the indoor antenna. 5. The indoor antenna distributes the amplified signal towards the subscriber's devices: smartphones, cell phones, modems and routers.
