CDMA 450-470 MHz cell phone jammers offered by jammerall is your preferred choice

Nowadays, with the wide popularity of cell phones, we are familiar with the CDMA. CDMA, short for Code-Division Multiple Access, uses a “spread-spectrum” technique whereby electromagnetic energy is spread to allow for a signal with a wider bandwidth. With CDMA technology, data and voice packets are separated using codes and then transmitted using a wide frequency range. Since more space is often allocated for data with CDMA, this standard became attractive for 3G high-speed mobile Internet use. CDMA is a military technology first used during World War II by English allies to foil German attempts at jamming transmissions. The allies decided to transmit over several frequencies to make it more difficult for the Germans to pick up the complete signal. Because Qualcomm created communications chips for CDMA technology, it was privy to the classified information. To block cell phones working on CDMA, CDMA phone jammers appear. Generally, there are two types of CDMA phone jammers, including the CDMA 850-894 MHz phone jammers and the CDMA 450-470 MHz cell phone jammers.

When compared with the CDMA 850-894 MHz phone jammers, you may find that it is very hard to find CDMA 450-470 MHz cell phone jamming blockers sales. That is because CDMA 450-470 MHz is not so widely used around the world. If you are also in need of a CDMA 450-470 MHz cell phone jamming blocker, here is your destination. Jammeral has prepared the newly developed 3W Portable CDMA450 Cell Phone Jammer. It can block the signals in several Isolating Signal Bandwidth including GSM 800MHz (851MHz-894MHz), GSM 900MHz (925MHz-960MHz), DCS 1800MHz (1805MHz-1880MHz), PCS 1900MHz (1930MHz-1990MHz) and 3G 2100MHz (2110MHz-2185MHz). The most important ability of this cell phone jammer is that it can effectively block the signal of CDMA 450MHz (450MHz-470MHz), which is beyond the reach of any other cell phone jammers. Although it is a mini portable cell phone jamming blocker which enjoys compact size and light weight, its shielding range can reach up to 20 meters, which is enough for general use. Equipped with car charger, it can also be applied in cars, which makes it convenient for drivers. In all, the special design and strong capability of this 3W Portable CDMA450 Cell Phone Jammer make it the best choice for those who are in need of a cell phone jammer working in this frequency band.
