I want to use this place clearly. Most schools use the test room type Quad Band Cell Phone Blocker suitable for long-term work, and the quality is good. Second, how big are we in the shielded area? For example, a room of 100 square meters is still a site of several thousand square meters. If the area is large, the power must be large. If the area is small, you must consider choosing an adjustable cell phone jammer shielding power. So which frequency bands need to be blocked? Are China Mobile, China Unicom, China Telecom, and CDMA all blocked? Still only need to block some frequency bands.
With a GPS jammer installed, the driver tried to put on an "invisibility cloak" for his taxi to evade inspections, but he didn't want to be caught. Today (7th), the Chongqing Traffic Law Enforcement Yuzhong District Brigade informed that the driver Han was not only fined 200 yuan, but the vehicle involved was also suspended for three days. According to the law enforcement officers of the Yuzhong District Traffic Law Enforcement Brigade, at 5 pm on March 4, they and the taxi industry self-discipline inspection team found that a Chongqing B5T5** number plate vehicle was inspected. Taxi stand at Caiyuanba. There is a black rectangular object on the center armrest of the front seat of the taxi, and a green light flashes on the black object. "At first we thought it was a walkie-talkie, but after a closer look, it turned out to be Quad Band Cell Phone Blocker and it was in use." Law enforcement officers then stopped the car. In the face of the law enforcement investigation, the driver Han said that he did not know about the incident, and it was the number one driver who did it. But when law enforcement officers asked him to provide the name and contact information of the lead driver, he, as the lead driver, also said he didn't know.
