Some technical problem of cell phone jammer should be analyzed

The manager is the advocate of the system reform of cell phone jammer company.
STK card with the original SIM card, like the ordinary GSM cell phones.
Parallel - usually used to say the parallel cell phone is actually divided into two categories: one for the smuggling of cell phones, these cell phones in general may not have any major problems of quality, but in reputation and sales services can not get reliable protection; second category is fake and shoddy products, these cell phones are mostly refurbished machines, there are various problems in itself, is very damaging to consumers. Bluetooth (Bluetooth) is a transmission range of about 10 meters short distance wireless communication standard, used to design the portable computers, cell phones and other mobile devices to establish a small, economic, and short-range wireless the link. As the band running in a unified, wireless data transfer rate up to 720bps to 1Mbps, includes a complete set of encryption and authentication mechanisms, it has a strong safety. The customer asks for the further technology perfection of cell phone jammer .
Bluetooth transmission distance determines that it can be used as a small local area network terminal equipment and other indoor or portable wireless devices to exchange data. Based on Bluetooth technology, a small device, just bring this lightweight device hidden in the headcell phone side without the need for direct use of communications equipment (cell phones, computers, etc.) can be achieved free calls. Nickel-cadmium battery is composed of two plates, one made of nickel, cadmium, another is doing, these two metals in the reversible reaction occurs in the battery, so the battery can be recharged. Nickel-cadmium is characterized as "strong" cheap. The disadvantage is cadmium metal pollution of the environment, the battery capacity is small, short life, so is the most low-grade nickel-cadmium batteries battery memory effect, charging will need a permit for each discharge, then recharge. Some technical problem of cell phone jammer should be analyzed.
NiMH batteries are nickel-metal hydride ions and synthesis, power reserve of more than 30% nickel-cadmium batteries, nickel-cadmium battery than the lighter, longer service life and environmental pollution, no memory effect. The disadvantage of NiMH batteries is the price a lot more expensive nickel-cadmium batteries, performance is worse than lithium. Lithium-ion battery materials, a high energy density batteries. Intelligent lithium-ion battery or a battery, it can be used with the original smart charger with dedicated, to the shortest charging time, the biggest life-cycle and the maximum capacity. Lithium-ion battery is the best performance of the battery. With the same size nickel-cadmium batteries, nickel metal hydride battery, the maximum power reserve, lightest, longest life expectancy, the shortest charging time, no memory effect.
