Choosing a Suitable Cellphone Signal Jammer Smartphones are quickly spreading and more people find necessary blocking cellphone signals for privacy, happiness, and freedom. A signal jammer’s ultimate function is to block cellphone signals with a wide variety of features and brands available in the market today. Some models of signal jammers have the capability of blocking wifi signal as well. An ordinary signal jammer can be used in a fixed room which needs a stable power supply. If you want a signal jammer that can be brought anywhere especially in places where there is no electricity, purchase one that is portable which can work with a battery. A portable cell phone signal jammer must be light as possible so you can take it easily with you. It is also important to consider the battery’s working time that best meets your requirement. Bands frequency, radius range, total output power, and antennas are the most common specifications of a cell phone signal jammer. The most essential part of a cellphone’s specifications is the band’s frequency. The compatibility of a mobile phone to certain network carrier determines its bands’ frequency. All networks of cell phones are using radio signals which can be interrupted. Band frequencies include CDMA 851 to 894MHz, GSM 925 to 960MHz, DCS 1805 to 1880MHz, PCS 1920 to 1990MHz, 3G 2110 to 2170MHz, 4G1 2300 to 2400MHz, 4G2 725 to 770MHz and WiFi 2400-2500MHz. A radius range refers to the jamming distances that it can block. Jamming distances depends on the signal strength and location. The actual amount of power refers to te total output power of radio frequency energy that a transmitter can produce. Antennas are specialized transducers used for converting radio-frequency fields into alternating current and vice-versa. Each the jamming device sends a signal using several antennas. A signal jammer’s blocking signal is stronger if it has more signals. Some antennas are externally located for a longer range. Before you purchase your own signal jammer, you need to consider the devices’ frequencies, power output, distance covered, power source, the amount of operation time, and the cooling system. The jamming device’s lifespan is much shorter than the jammer with a good cooling system. If you are planning to also secure your vehicle, all you need is to purchase a signal jammer which has the capability to block cellular frequencies and GPS with a five to fifteen-meter range.
