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 to bring your signal jammer in some places where there is no power supply, there are portable ones available that can work using a battery. You need to consider the weight when buying a signal jammer so you can take it easily. It is also important to consider the battery’s working time that best meets your requirement. The different specifications of a signal jammer include bands frequency, radius range, total output power, and antennas. The bands frequency is the key feature of most cellphones’ specifications. The compatibility of a mobile phone to certain network carrier determines its bands’ frequency. All cellphone networks are using radio signals are they can all be interrupted using a signal jammer. The different band frequencies are 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 signal jammer’s radius range pertains to the distances it can block. The actual distance that can be jammed varies depending on the strength of the signal and the location. Total output power refers to the amount of power of the energy of radio frequency which a transmitter produces. Antennas are specialized transducers used for converting radio-frequency fields into alternating current and vice-versa. Jamming devices use different antennas in sending signals. A signal jammer’s blocking signal is stronger if it has more signals. In order to reach e a longer range, some antennas are located externally. 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 lifespan of an ordinary signal jammer is shorter compared to one with a good cooling system. If you are planning to secure your car, you need a jamming device that can block cellular frequencies and GPS with a five to fifteen-meter range.
