Driver Cell Phone Blocking Technology

Mobile phone wifi hotspot is a technology that converts GPRS, 3G or 4G signals received by mobile phones into wifi signals and sends them out, so that portable devices such as mobile phones, tablets or notebooks can pass through wireless network cards or wlan modules, and can also be outdoors or where there is no network. Be able to surf the Internet and realize network resource sharing. The mobile phone must have a wireless AP function to be used as a hotspot. At present, most smartphones have their own hotspot function. WiFi hotspot wireless access has become a standard way for many devices to access the Internet. If you carry a portable device that supports Driver Cell Phone Blocking Technology when you are away, such as PSP, iPad WiFi version, etc., you have to find a place that provides free WiFi wireless hotspots, such as Starbucks, McDonald’s, Country-based or designated by the hotel. Only the area can be connected to the Internet. This directly limits the significance of portable devices that are easy to carry. At the same time, these devices do not have network access conditions such as 3G or GPRS, so are they unable to access the Internet at any time? In fact, as long as you have a mobile phone with an Android system, you can You turn your mobile phone into a WiFi hotspot via the GPRS network, and then turn on the iPad, you can make the iPad go online at any time, which is very convenient. cell phone jammer

In fact, the signal emitted by the mobile phone WiFi hotspot is the same as the WiFi signal frequency band and the Bluetooth frequency band emitted by the router. The Wi-Fi technology is defined by IEEE 802.11b/g/n, and its working frequency is 2.4ghz, of which the 2.4ghz spectrum is Divided into 14 overlapping and staggered 20 MHz wireless carrier channels, the center frequencies of which are 5 MHz respectively. 802.11a/n has more channels in the 5.0ghz spectrum. 802.11n also uses channel welding technology to merge two 20MHz carrier channels into a 40mhz channel to increase throughput. Driver Cell Phone Blocking Technology By transmitting signals in the above frequency bands, mobile phones and other communication devices within a certain range can receive the signals transmitted by the mobile phone signal jammer, thereby achieving the purpose of shielding the signals.
