Although mobile phones are convenient, they often lead to the leakage of privacy. For example, in special meetings and occasions where confidentiality is required, some people will use mobile phones to collect confidential information. And these occasions have made mobile phone jammers a demand, and this demand has also attracted the attention of some law enforcement agencies. Therefore, on a global scale, some countries prohibit the sale of mobile phone jammers. It’s like America.

What is a cell phone signal jammer?

A mobile phone signal jammer is a small box with a signal transmitter, which can be generated at the same frequency as a mobile phone signal, thereby blocking normal communication. This method is similar to a base station, using a disordered base station to occupy the normal channel of the mobile phone. It’s just that this small box has very little power and doesn’t take up a lot of range. Usually, mobile phone signal jammer will adjust different frequencies according to different countries, because the channels used by 4G, 5G signals may be different in different regions. Therefore, mobile phone signal jammers cannot be used globally. The manufacturer must also customize the corresponding signal according to the user’s country.

The best 4 cell Phone jammer models.

Generally, there is no need to distinguish between good and bad mobile phone signal jammers. From the functional requirements, we have summarized the following 5 most popular mobile phone signal jammers.

1. 8 Bands Portable Cell Phone Jammers

If you are looking for a device that covers 4G signal and 3G, 2G signal. This device will be the best value for money. The device can cover 4G LTE and 4G Wimax, so the vast majority of 4G signals will be blocked. GSM signal is already covered. At the same time, the device supports the shielding of WIFI and Bluetooth signals and the shielding of GPS civil signals. It is the most functional and commonly used device within 5 to 20 meters (depending on the environment and signal strength).

2. 10 Antennas Military Jammer

If you are looking for a device that covers 5G, 4G signals. The device meets your requirements. The device can cover the 5G conventional scheme, and the signals below 4G have also been blocked. And the device supports shielding WIFI and Bluetooth signals and also supports shielding 5.8G (WIFI signal).It is the most functional and commonly used device within 5 to 20 meters (depending on the environment and signal strength).

3. Portable Cell Phone Blocker with Cooling Fan

If you are looking for the easiest and cheapest 4G signal jammer. You can try this device. Although it only has 4 antennas, it can support regular 4G LTE signal shielding. 3G 2G signal coverage is also no problem. Although it does not support the shielding of WIFI and GPS signals. It is useful in some cases where the requirements are relatively single.

4. 6 Antenna Portable Signal Jammer Blocker

This 6-antenna device can block regular 4G LTE signals, WIFI signals, and GPS signal. It is also a relatively conventional configuration. But it lacks 4G Wimax. So it is not recommended for European customers to buy it.

How to use a cell phone signal jammer?

Mobile phone signal jammers usually need to install antennas first, and these antennas are usually marked according to their length or number. The user only needs to install these antennas normally, charge the mobile phone signal jammer with a charging device, and then turn it on, the machine will work within 5 seconds after turning it on. At this time, the user can try to use the mobile phone to make a call, and it is normal if a busy signal is encountered.

What is the difference between a GPS, WIFI jammer and a mobile phone jammer?

Like other signal jammers, GPS jammers and WIFI jammers are only different in function, and the principle is the same, but because of their high power, 5.8G jammers must use high-end equipment to produce results, so most manufacturers will require fixed Several devices can support 5.8G.

Summarize

The mobile phone signal jammer is a kind of security equipment, which is used in special scenarios. Please purchase it selectively according to local laws and regulations.

The 3GPP B1 (2100 MHz) LTE band is the sixth most popular band used by public mobile operators for LTE network deployments, and is typically deployed due to the existing regulatory framework in place governing 2100 MHz spectrum, as well as the ability for operators to refarm unused spectrum allotments for 4G. 2100 MHz band 1 spectrum provides a good compromise between capacity/density and penetration/range.

Mobile carriers have flexibility to deploy LTE using band 1 as a single band or as part of a multi-band network, with reportedly over 50 mobile networks deployed (April 2018). LTE-A or LTE-Advanced Pro technologies can be deployed using carrier aggregation to combine various bandwidths of band 1 with other carriers.

The mobile phone signal used in the UK is similar to the European mobile phone signal. There are a total of 5 different frequencies used in the UK used by the mobile networks to deliver their 2G, 3G and 4G mobile services.

• 800MHz (Band 20)
• 900MHz (Band 8 )
• 1800MHz (Band 3)
• 2100MHz (Band 1)
• 2600MHz (Band 7)

What frequencies do the different operators use?

Each operator in the UK utilises different frequencies to deliver their mobile networks with the core networks being EE, O2, Vodafone and Three. Then there are also operators, called mobile virtual network operators (MVNO), who utilise the backend of the core networks to offer their own services.

The frequencies used by the major UK networks are listed below:

	Network Frequencies	Check Coverage
EE	800MHz (4G)  1800MHz (2G & 4G) 2100MHz (3G) 2600MHz (4G)
O2	800MHz (4G)  900MHz (2G & 3G) 1800MHz (2G) 2100MHz (3G)
Vodafone	800MHz (4G)  900MHz (2G & 3G) 1800MHz (2G) 2100MHz (3G) 2600MHz (4G)
Three	800MHz (4G)  1800MHz (4G) 2100MHz (3G)

Frequency converted into bands: 800MHz (Band 20), 900MHz (Band 8), 1800MHz (Band 3), 2100MHz (Band 1) and 2600MHz (Band 7)

The frequencies used by UK’s MVNO’s are listed below:

Virgin Mobile	1800MHz (2G & 4G)  2100MHz (3G) 2600MHz (4G)

How can I find out which operators my phone is compatible with?

In order to check if your phone is compatible you need to get your phone specification from your manufactures website and find out the frequencies and bands it supports which you can then reference to the tables above.

In order to get maximum speeds and coverage you want your phone to support all the bands offered by an operator, but don’t forget to check coverage and speeds in your area before making a final decision.

How about a 4g cell phone signal jammer?

At present, it has been gradually upgraded to a 5G network, you can purchase a 4G jammer, but a 5G jammer is also a good choice, although it will be more expensive.

What are the advantages/disadvantages of the relevant 4G frequencies?

Three different frequency bands are used for 4G LTE in the UK. There’s the 800MHz band, the 1800MHz / 1.8GHz band and the 2600MHz / 2.6GHz band.

800MHz frequency band

The 800MHz frequency band is one of two which was auctioned by Ofcom in February of 2013. Previously this band was used to provide analogue television signals, but since TV’s switched over to digital it was freed up to be used with 4G.

The lower the frequency of the band the further it can travel, so the 800MHz band is the most adept of the three at travelling over long distances, which means users can get a 4G signal even when they’re a long way from a mast. This becomes particularly useful in rural areas where masts are likely to be quite spread out.

However, it also has some advantages in cities, because low frequencies are also good at passing through walls and other physical objects. So the 800MHz band is good for indoor coverage and for heavily built up areas where a signal might otherwise struggle to travel.

On the other hand it has a comparatively low capacity, as it was only available in small 5 and 10MHz blocks, which means that it can’t always deal brilliantly with lots of people trying to connect at once, particularly if they’re carrying out demanding actions such as streaming HD video. So even in places with a good connection it may not always deliver consistent speeds, especially in urban areas where there’s likely to be a lot of data traffic.

2.6GHz frequency band

The 2.6GHz band is the other frequency which was auctioned by Ofcom and it’s essentially the opposite of the 800MHz band. So it’s not great at travelling over long distances, meaning that masts need to be closer together to deliver reliable coverage and as such it’s not so suited to rural areas.

It’s also not all that adept at penetrating walls so indoor signal on the 2.6GHz band won’t always be perfect.

But on the other hand with 35MHz blocks available it has a high capacity. So it can cope with thousands of simultaneous connections, which in that sense makes it a good fit for cities and other busy areas.

1.8GHz frequency band

Unlike the other two frequencies the 1.8GHz one wasn’t auctioned, instead it’s a frequency band which EE already had access to and which now Three does too. As you might have guessed, the 1.8GHz band falls somewhere in the middle of the other two.

Which network is in the best position when it comes to frequencies?

The easiest way to see just how the network’s stack up is perhaps to put it into a table, as below:

It’s clear from the table that EE is the only network that’s covering all its bases. It’s also worth bearing in mind that the more MHz of each spectrum a network has the better and more consistent the connection can be and the more future-proofed it is.

With that in mind EE is well prepared for future data demands, with a whole lot of 1.8GHz spectrum, which covers an ideal middle ground, as well as quite a lot of 2.6GHz spectrum and a bit of 800MHz spectrum.

O2 is on paper in the worst position, as while it has more 800MHz spectrum than any network other than Vodafone that’s all it has. So its 4G network should be good at covering rural areas and providing indoor coverage, but it’s not likely to have the same capacity as its rivals. On the other hand O2 has a large network of Wi-Fi hotspots to help out in city centres.

Vodafone has an identical amount of 800MHz spectrum but also has a lot of 2.6GHz spectrum, so it should be quite well served to cover data requirements in the future, as well as being better positioned to provide reliable coverage to rural areas than EE or Three.

Three meanwhile only has a little 800MHz spectrum and no 2.6GHz spectrum, but with 2 x 15MHz of 1.8GHz spectrum it should be fairly well equipped to provide both indoor and outdoor coverage

Conclusion

Going purely on the frequencies and amounts of spectrum that each network has EE is in by far the best position, while O2 may struggle the most to keep up with data demands, particularly in urban areas.

Neither Three nor Vodafone can quite match EE but they should be fairly well served, especially Vodafone, which has the extremes of both the 800MHz and 2.6GHz bands covered quite well, even if it has no spectrum in between.

4G is the short name for fourth-generation wireless, the stage of broadband mobile communications that supersedes 3G (third-generation wireless) and is the predecessor of 5G (fifth-generation wireless).
The 4G wireless cell standard was defined by the International Telecommunication Union (ITU) and specifies the key characteristics of the standard, including transmission technology and data speeds.
Each generation of wireless cellular technology has introduced increased bandwidth speeds and network capacity. 4G users get speeds of up to 100 Mbps, while 3G only promised a peak speed of 14 Mbps.

What is difference between 4G and LTE?

So what’s the difference between 4G and LTE, and is 4G or LTE better? In short, 4G offers a much faster speed, more stability and access to a larger variety of online activities. LTE is a half-point between 3G and 4G, so its performance suffers compared to the fourth generation.

What is the difference between 4G and 5G?

The biggest difference between 4G and 5G is latency. 5G promises low latency under 5 milliseconds, while 4G latency ranges from 60 ms to 98 ms. In addition, with lower latency comes advancements in other areas, such as faster download speeds. Potential download speeds.

Should my phone say LTE or 4G?

4G vs. LTE. In laymans terms, the difference between 4G and LTE is that 4G is faster than LTE. The reason for this is that 4G meets the technical standards designated for it whereas LTE data transfer speed standard is merely a stopgap measure standard devised until actual 4G speed is realized.

How long before 4G is obsolete?

T-Mobile announced that it will finish shutting down Sprint’s 3G CDMA network by March 31, 2022 and Sprint’s 4G LTE network by June 30, 2022.

Will 4G phones still work in 2022?

T-Mobile and Sprint 3G/2G/4G LTE network shutdown dates

These are January 1, 2022 for Sprint’s 3G network sunset, and June 30, 2022 for the 4G LTE connections, respectively.

How are signals classified?

Two main types of signals encountered in practice are analog and digital. The figure shows a digital signal that results from approximating an analog signal by its values at particular time instants. Digital signals are quantized, while analog signals are continuous.We use analog signals as the main wireless communication signals in our daily life.

Therefore, mobile phones also use analog signals to communicate. Like 2G, 3G, 4G, and 5G signals.The WIFI signal also has 2.4G, 5.8G, and other frequency bands.

For the jammer, how do we choose the corresponding signal frequency band?

First of all, what is our purpose?For example, if we only want to block mobile phones, then we can first imagine the types of signals that the mobile phones we need to block are mainly used locally. If we are in very remote villages and towns, maybe we only need a 2G jammer, because there is no 4G signal in those places. Or in some 5G places, we must choose a jammer with a 5G signal at this time.

Or we want to block the WIFI signal, but we know that the WIFI in this area only has 2.4G signal communication. Then we can not choose the 5.8G device, otherwise we need to choose.

For GPS, we also need to know the difference between military and civilian use. This makes it easier for us to know what we need to block.

Where can I buy a custom signal jammer?

You can go to our customize jammer channel to customize your signal jammer. The price is slightly higher than a normal off-the-shelf device because most devices don’t require customization. Regardless, the price is still decent, and it’s still cheaper than most platforms.

Maximum Distance

A typical cellphone has enough power to reach a cell tower up to 45 miles away. Depending on the technology of the cellphone network, the maximum distance may be as low as 22 miles because the signal otherwise takes too long for the highly accurate timing of the cellphone protocol to work reliably. Usually cellphone signals don’t reach anywhere near these maximum distances. Typical cell size outside of urban areas means cellphone signals may have to travel up to several miles.

Sources of Interference

Cellphone signals are in a frequency range that travels in a straight line and has limited penetration capabilities. Interference weakens the signal and means that cellphones may not be able to reach a cell tower that is quite close. Sources of interference are natural obstacles such as hills and trees or man-made structures such as buildings, walls and tunnels. In urban areas, cellphones blocked from one cell tower may connect to another one nearby, but in rural areas, interference with coverage from a single cell tower may make reception unreliable.

Capacity Planning

Carriers often reduce the distance between a cellphone and a cell tower due to capacity issues. A cellphone carrier receives a certain number of frequencies to use in his network at a given location. Each cell tower can handle a maximum number of calls determined by the number of separate frequencies. If the carrier expects that his customers may make more calls, he reduces the size of his cell and re-uses the frequencies in a neighboring cell. This means that, especially in urban areas, cell towers may be a fraction of a mile from the cellphone.

Cell Size

When cell sizes in a cellphone network shrink, carriers reduce the power of the transmitters on their cell towers to eliminate interference with neighboring cells using the same frequencies. Operating on such low power, a cell tower may have to be within a few hundred yards of a cellphone for the cellphone to pick up its signal. If interference blocks one tower with a weak signal, a cellphone may connect with another nearby tower.

What is the range of 4G tower?

4G wavelengths have a range of about 10 miles. 5G wavelengths have a range of about 1,000 feet, not even 2% of 4G’s range. So to ensure a reliable 5G signal, there needs to be a lot of 5G cell towers and antennas everywhere.

How far can a 5G signal travel?

In general, the 5G Ultra Wideband network’s signal can reach up to 1,000-1,500 feet without obstructions. Verizon is leveraging small cell technology to help deliver more 5G signal which directly increases the coverage and speed of the network.
