Why We Can't Make and Receive Calls at the Gas Station

Posted on 12th Jun 2015 @ 9:00 AM

Today what we want to talk about is from video ,it is real ,not a story.A driver stopped his car at a gas station after a long journey,his car needed to be refueled.The guy ,certainly knew “No Smoking”well ,unfortunate he did not understand mobile phone using also be banned in gas station.And he did not see the warnings.He stood by the side of car and checked the oil cylinder,his mobile phone rang--he received the phone immediately without any hesitate...Tragedy happened in next second,a huge explosion destroyed the whole gas station...

Why we can't make and receive calls at the gas station.Before answering the question ,we would like to introduce the signal blocker/jammer blocker.Just as it’s name implies,the product mainly works for banning signal,kinds of signal :cell phone ,,wireless radio,walky-talky,GPS, Bluetooth and Wifi.For the product ,it is a mult-purpose signal blocker / jammer blocker to keep the gas station jam-free.Signal bandwidth of the jammer blcoker are :signal bandwidth,DCS/PCS:1805-1990MHz  3W,3G:2110-2170MHz 1.5W,4G LTE:725-770MHz 3W,4G LTE:725-770MHz3W,4GLTE:1710-1770MHZ1.5W,4GWimax:2345-2400MHz1W,4GWimax2620-2690MHz1W,WiFi:2400-2500MHz1W, WiFi:2400-2500MHz1W,WiFi:2400-2500MHz1W,UHF:400-470MHz 3W,GPSL1:1570-1580MHz 1.5W,Lojack:167-175MHz 3W. And have a powerful banning scope ,up to 50 meter.If there is a big gas station ,we can make several sign al blocker work together.

Okay,the next is the reason why we can’t do so at the gas station.Gas molecular diffuses during the process of refueling,density around the car is enlarged in a short time.We know mobile phones are not blast-proof ,and use high frequency to ensure the high definition signal.When the high strength cell phone signal meets computer equipment ,what will happen?A explosion.Because it just needs a low current to burn gas ,electrostatic current in the working state of cell phone can reach the point.Especially in raining day and foggy day,bad ventilation,will improve the explosive possibility.By the way ,a research by Dr.Glenn Ziggy from University of Oklahoma,shows us ,calling at the gas station can not cause fire and explosion.Anyway,it still be a safety loophole so we can not venture to calling in the dangerous places.
