A mobile signal booster antenna works by capturing weak signals from nearby cell towers, amplifying them, and then rebroadcasting the strengthened signals within its coverage area. This helps improve the mobile signal strength and reception for devices like phones or data cards. The booster typically consists of an external antenna to receive the weak signal, an amplifier to boost it, and an internal antenna to broadcast the enhanced signal within a confined space.
Both antennas are similarly constructed but the air inductor of the outer antenna has a turn number of 9 to 11 and the inner inductor has a turn number of 5 or 6.
Great signals are between -30 to -79 dBm, a Good signal would be -80 to -89 dBm, and anything -90 to -99 dBm is Average. If your signal is -100 to -109 dBm you are Below average and -110 to -120 dBm is Poor.
Mobile signals operate in a range of frequencies, depending on the technology and region. In general:
1. **2G (GSM):** Operates in the 900 MHz and 1800 MHz bands.
2. **3G (UMTS):** Uses frequencies around 850 MHz, 900 MHz, 1900 MHz, and 2100 MHz.
3. **4G (LTE):** Utilizes various bands, including 700 MHz, 850 MHz, 1800 MHz, 2600 MHz, and others, depending on the country and carrier.
4. **5G:** Operates in a range of frequencies, including sub-6 GHz bands (around 600 MHz to 6 GHz) and millimeter-wave (mmWave) bands above 24 GHz.

These frequency bands vary globally, and different countries may use different bands for their mobile networks.
