Texas beauty school’s need with 5W adjustable cell phone jammer?

Seeking a quiet atmosphere in the classrooms, a cosmetology school located just outside Dallas opted to utilize a 5W adjustable cell phone blocker. This choice, along with the presence of three additional jammers waiting to be configured, set off a series of events that unfolded last week.

Phonejammer.com, a company based in London, has been under the FCC's watchful eye for quite some time. In 2008, the agency issued a citation to Phonejammer (PDF) for their marketing of radio frequency devices specifically intended to interfere with cellular and PCS frequencies in the United States.


The company denied marketing these products in the US, where they are prohibited, but FCC staff noted that the signal blocker were priced in US currency, the default shipping location was set to the United States, and the site included testimonials from US citizens who had purchased phone jammers from Phonejammer. Furthermore, the jammers on the site were specifically designed to target US cellular and PCS frequencies.

You might suspect that the interests of the federal government in your business practices might be reason enough to change them, but then again, you don't run Phonejammer. On November 9, 2009, the FCC received a complaint (apparently from AT&T) about cellular interference in the 800MHz and 1900MHz bands. Staff from the FCC's Texas field office tracked the problem to the Cosmetology Career Center in Carrollton, Texas and found a 5W jammer on the premises (PDF).

When contacted by the FCC, Phonejammer's attorney claimed that the company has not shipped or distributed any units to the United States.

At a price of $395, the 5W jammer provided by the Cosmetology Career Center is equipped with two antennas and has a jamming radius of 2-25m. It is designed to block PCS, GSM, and CDMA signals between 850MHz and 2100MHz. The website indicates its "operating location" as South America and Africa.

In a peculiar turn of events, it is legal to openly carry firearms into a Starbucks in both Texas and Florida, while the use of phone jammers is not permitted. Consequently, when a loud cell phone conversation disrupts the peace at a nearby table, individuals are left with the choice of either enduring the disturbance or resorting to using a firearm. This situation prompts a reevaluation of existing public policy standards.

If the cell phone signal blocker is stored in an area with a temperature lower than 0 ℃, its normal use will be affected and its internal components will be damaged; If the room temperature exceeds 40 ℃, the product may also be damaged. The magnetic field will affect the normal operating frequency of the machine. You need to know how the phone jammer works. So we need to pay attention to this. The newly designed jammer is specially designed to block signals. It should be between - 40 and+75 degrees Celsius. The best choice is to purchase a wireless signal smartphone blocker. I think it is very suitable for cinemas, libraries and other places. Nonmagnetic attenuators are also very important components that can interfere with our equipment. GPS signal jammers can be used to block GPS signals to help ensure safety. Do not use your mobile phone to receive signals. It is important to keep the storage temperature within a certain range. In order to improve this situation, I bought a mobile ...

Top Ten Questions About Interference

Image
why install a jammer? the jammer can be used almost anywhere, but it is mainly used in places where telephones can be particularly disruptive, as it is expected to remain quiet, such as entertainment venues. what is the function of a signal shield? a signal jammer can be a handheld portable device that can block wireless communication within a radius of 15 meters. cell phone blocker can be purchased or self-made. these jammers are relatively inexpensive and interrupt communication on specific frequencies, mainly used to protect personal privacy and security. will signal shields affect wifi? signal interference can overwhelm the target signal frequency and prevent nearby users from sending or receiving data. all devices that transmit or receive wireless signals through specific frequencies are susceptible to interference. therefore, interference may target wi fi, bluetooth, gps, and wireless communication how far does the wifi blocker work? the effective distance of the 5...

Home invasion suspects use cell jamming techniques to evade surveillance cameras

Cell interference The use of devices to interfere with radio or wireless signals. In some burglaries, thieves have figured out how to use technology to evade surveillance cameras. This is called cellular interference, and it happens when a person uses a device to interfere with radio or wireless signals. According to the FCC, "The use of telephone mobile jammers , gps blocker interceptors, or other signal jamming devices designed to intentionally block, interfere with, or interfere with authorized radio communications violates federal law." There are no exemptions for use in businesses, classrooms, homes or vehicles." Cell interference may occur with devices or home cameras approximately 30 feet from the intended target. Video from the south Charlotte neighborhood showed a suspect crawling across the yard at night, but not all of the incidents were caught on camera. "Any time you have a wireless device, whether it's on Wi-Fi and so on, you know people a...
