Is there a cell phone signal blocker that can be used on a neighbors devices?

The ability to communicate with others at all times is truly advantageous. Nevertheless, the excessive use of cell phones in restaurants, movie theaters, concerts, shopping centers, and churches has led to disruptions, as some individuals do not know when to cease their conversations.Is there anyone who hasn't felt annoyed by being privy to a conversation about a very personal issue, where the speaker discloses intimate details to their friend and the people nearby?

Despite most people merely grumbling and moving forward, there are those who resort to extreme measures for retribution. Cell phones, essentially functioning as portable two-way radios, are susceptible to signal disruption or jamming, much like any other radio device.

The function of jamming devices is to overpower cell phones by transmitting a signal on the same frequency and with enough power to cause the two signals to collide and negate each other. Cell phones are equipped to enhance their power in the presence of low-level interference, therefore the signal jammer must be capable of identifying and matching the power increment from the phone.

Cell phones are designed as full-duplex devices, utilizing two distinct frequencies for talking and listening simultaneously. Certain jammers disrupt one of the frequencies used by cell phones, causing both frequencies to be blocked. This results in the phone being misled into thinking there is no service available, as it can only receive one frequency.

Basic devices are capable of blocking a single group of frequencies, whereas advanced wifi jammer can simultaneously block multiple types of networks. This prevents dual-mode or tri-mode phones from automatically switching between different network types in search of an available signal. Certain high-end devices have the ability to block all frequencies simultaneously, while others can be adjusted to target specific frequencies.

To disrupt a cell phone signal, one only needs a device that can broadcast on the right frequencies. Despite differences in signal processing among various cellular systems, all cell phone networks utilize radio signals that are susceptible to interruption.Europe and Asia employ GSM in digital cellular and PCS-based systems, utilizing the 900-MHz and 1800-MHz bands, while in the United States it operates within the 1900-MHz (sometimes referred to as 1.9-GHz) band.Jammers have the ability to transmit signals on various frequencies, enabling them to effectively disrupt AMPS, CDMA, TDMA, GSM, PCS, DCS, iDEN, and Nextel systems. Regardless of whether it is an old-fashioned analog cell phone or a modern digital device, both types are equally prone to being affected by jamming.

The actual range of the gps jammer depends on its power and the local environment, which may include hills or walls of a building that block the jamming signal. Low-powered jammers block calls in a range of about 30 feet (9 m). Higher-powered units create a cell-free zone as large as a football field. Units used by law enforcement can shut down service up to 1 mile (1.6 km) from the device.

I'll give you a serious answer since many others won't. I know from experience that, yes, your neighbor COULD have such a device. They're rather inexpensive. $150 can get someone a cell phone jammer conveniently delivered to their door.

Is it likely though? Anything is possible. You never really know who your neighbors are. I move around a lot & after all the awful neighbors I have had, I put nothing past anyone.

FCC probably won't take your claim seriously without proof. Just repeat the performance a few times & record the results. However, if the guy has a gsm jammer it would probably be best not to talk about your test out loud.

Reason being, when someone has a jammer, they usually also have a listening device. No, I am not joking. Every person in this would be paranoid if they knew the number of people who buy listening devices so they can spy on their neighbors for shits & giggles....or worse more malicious reasons.They're easy to acquire & work wonderfully. Don't talk about your plan to test him so you can record it. If he has a jammer, chances are that he's the type to have such a device to listen to you in your home.
