Eliminating Noisy Commuter Calls – Cheap Cell Phone Jammers – Hidden Costs: In the last week a Chicago vigilante has appeared in court charged with using an illegal cell phone blocking device on the public transportation system. Details (including how expensive these activities can get) below.

We have all had the experience of using public transportation and being subjected to a fellow passenger’s noisy cell phone conversation. For those of us who like to enjoy a good book or newspaper in silence it can be very distracting to hear a debate about ‘whether lasagne or coq au vin would be better for tea?’, or ‘how the treatment aunt Mildred’s bunions is progressing’, or graphic descriptions of Veronica next door’s promiscuous life style and ‘whether that cold sore on her mouth really did come from Herpes Henry at the liquor store’.

Over 30 years ago I remember how using a mobile phone for business was a far more civilised affair. I was one of the first people in BP to hire an international ‘mobile’ comms device for my negotiations with Istanbul while I was travelling through Belgium. I picked up the device with my hire car at Brussels airport. It came in a huge suitcase and when I needed to use it I had to stop the car, fix an enormous antenna onto the roof and then dial up my customer using a contraption that was the size of a building brick. Needless to say I didn’t bother any other commuters with my calls in those days (and I did get the deal!)…..I kept the phone book in my Sinclair ZX Spectrum!

As mobile devices for inflicting pain on fellow commuters have grown smaller and become more ubiquitous (a bit like Henry’s herpes) travellers have adopted desperate measures in their search for peace. One such traveller was a 53 year old Chicago commuter who regularly used the local CTA Red Line train to get to work. From pictures I have found of this gentleman on the internet I understand he had been utilising his anti-cellphone technology for some time.
In the earlier photos he was clearly brandishing what looked like a large old (‘retro‘) mobile communication device but with a notable distinguishing feature – it had 5 antennae. This vigilante of the ‘peace’ was brandishing a cell phone jamming device which effectively prevented anyone from using their cellphone within a certain radius of where he was sitting.

The transport authorities and the police managed to track down this jammer by using their own hi-tech equipment and monitoring him while he was operating his device on the train. As a result the commuter ended up before a Chicago judge last Wednesday charged with one felony count of unlawful interference with a public utility for his alleged actions between the Loyola and Granville stops (on the public transport system). The 63 year old was held in lieu of $10,000 bail.
In the USA, as in many other countries, interference with the operation of the public communications network is illegal. According to the Federal Communications Commission enforcement bureau the unlawful use of a jammer is a criminal offense and can result in various sanctions, including a jail sentence. More specifically, the unlawful marketing, sale, or operation of cell phone, GPS, or other signal jammers in the U.S. can result in:
- significant fines (they call them “monetary forfeitures”) – up to $16,000 for each violation or each day of a continuing violation, and as high as $112,500 for any single act;
- government seizure of the illegal equipment; and
- criminal penalties including imprisonment.

The Federal Communications Commission has produced a very comprehensive set of frequently asked questions and for the convenience of visitors to ChrisDuggleby.com I have made a PDF copy available (Federal Communications Q and A sheet on Cellphone Jamming).
It is not only the USA where cellphone jamming is illegal. In the UK usage of jammers is illegal with the exception of their official use in prisons (since 2012). In Germany the use is also illegal with potential fines of upto €500,000 (info from the Bundesnetzagentur). Once again jamming is possible by the German prisons’ authorities to prevent prisoners using forbidden mobile devices. You can not order these jammers over the internet in Germany – their import is forbidden.
The reason for the illegality of such devices is because, in addition to blocking irritating commuters, they can also disrupt emergency calls.
So, in conclusion if you are situated near to someone who insists on sharing the details of their call with you the only simple course of action is to politely request that they speak more quietly (and remember this when you next use your own cellphone in a public place!).
