Q&A for Signal Jammer

March 15,2019 | Edit by:Trayman

 

 

 

Q: I wanna shielding the drone.

A: First of all, you should know the main parameters of the Jammer is consist by: Target jamming frequencies, and the output power. 

Then, when your purpose is aim to intercept the drone, you should clear what frequency the drones are using. We had conclude following bands for generally use and they are subject to change to the actual require. So when you want buy a signal jammer, you’d better check your target jamming frequencies first.

 

Typical Drone Jammer Frequency

Item

Frequency

2.4G

2400-2500MHz

5.8G

5725-5850MHz

GPS L1

1550-1620MHz

GPS L2

1100-1300MHz

 

 

 

Q: I need a Jammer to cover the full bands.

A: This question we had met a lot. Actually there is no right answers to explain what is the standard of the full bands, we need the information which is quantitative but not qualitative. For example, when you describe a massive building, you have to tell us the hight, how many acreage it take to support your view that the building is big, what's more, it must reflected on the specific infromation or data. So please provide us more details!

 

BTW, the property of power amplifier was decide by transistor specification which had fixed its ability to work in specified range. We only can do what they can achieve.

So, when you need a Jammer, please confirm your target jamming frequencies first. Whereas it will influence the local BTS when uplink got intercepted and it is illegal in some countries, so basically we will jam only the downlink. 

Also, here we offer a list which works for general mobile and wifi bands for reference:

 

Prison Jammer Frequency

VHF

137-174MHz

UHF

380-470MHz

GSM

700-800MHz

851-894MHz

925-960Mhz

DCS

1805-1880Mhz

3G

2110-2170Mhz

LTE

2400-2483Mhz

GPS L2

1150-1300MHz

GPS L1

1550-1620MHz

WIFI

2620-2690Mhz

5.8GHz

5.725 – 5.875Ghz

 

 

 

Q: What’s the effect range of your jammer?

A: As mentioned in above content, jammer main specification is consisted by frequency and output power. Without a doubt, more powerful can impact on a longer rage. However, there is another issue that will influence the jamming range, and it’s your local signal strength. Please check on following comparison table:

Our product will only ensure the output power due to the reason that various factor can influence the jamming range. For example: 

When your target site is near by the local BTS or signal strength at a good state, the jamming range might shorter than site where signal is worse.

Besides that, there still other factors like: The weather, obstacles, terrain etc. can impact on jamming effect. 

 

In our comparison table, you can according to the signal strength which you measured at aim site and find out each frequency band corresponding to our estimate jamming range.
