How much does home cell phone signal blocker that can block WiFi cost?

As a parent, I don’t know if you also have this kind of trouble. Children don’t sleep in the middle of the night, play games on mobile phones, delay rest and study, and don’t listen to parents’ discipline. What should I do if this happens? Some parents think of home mobile phones Signal blocker, the current mobile phone signal blocker can basically block 2/3/4/5G mobile phone signals and 2.4G WiFi, which can solve the problem of children playing mobile phones at home.

In poor cellular coverage areas where you have a decent WiFi signal, WiFi calling will help save battery life. In cases where you have low or no cellular signal, you may want to consider turning off cellular to preserve your battery. However, if you are not connected to a WiFi network, leaving on wifi blocker can drain your battery.

Most of the shielding devices mainly interfere with the uplink signal. The reason is that the transmission power of the mobile phone is 23dbm, which is 2 watts. As long as the mobile phone (UE) is prevented from transmitting signaling to the base station, the shielding function is basically realized, causing the UE and the base station to be blocked. Signaling interaction is not possible. The main principle of the shielding instrument is to scramble a certain frequency band (most of the upstream frequency bands) and transmit useless signals.

Therefore, whether it is 2.4GHz of wifi, LTE GSM or even the latest NR, it is easy to achieve the purpose of interference.

But how much does this kind of home cell phone jammer cost?

Cost – So, first things first, how much would it cost you? You can get the cheapest jammers (those which can only block a very specific type of signal – mobile signal, for example) for around $30 to $60. Pretty affordable, right ? On the other hand, they tend to work on batteries, only for a short amount of time, and cover small area alone (around the size of a person’s body).

If you decide to buy one of the pro models, you must invest a serious amount of money behind it – at least 500$. On the upside, you don’t have to worry about getting separate GPS or Wi-Fi jammers. More often than not, these models are able to block all sorts of signals including Cellular, Wi-Fi, GPS, Bluetooth, and Radio Communication.

There is no difference between the home mobile phone signal blocker and the test room mobile phone signal blocker in many places. For example, the shielded signal frequency bands are all band shielded, which means that 2/3/4/5G mobile phone signals and WiFi signals can be shielded; The difference lies in the shielding range. The shielding range of the signal jammer in the examination room is generally about 100 square meters, covering the entire classroom examination room.

As long as the shielding range of the home signal jammer can shield the child’s room, the area is basically within 20 square meters. If the shielding area is too large, it may affect the normal use of mobile phones by neighbors, and it is easy to be complained. Therefore, when choosing a home mobile phone signal jammer, you can choose one with lower power, so that the price of the jammer gps will be lower.
