Experimental verification of selected risk factors disrupting ecall system function

standards, its manufacturers are forced to adapting, developing and implementing new design features increasing level of passive protection of passengers as well as implementing systems affecting active protection level. Both of these kinds of protection help to reduce the severity of subsequent damage to passegners during an accident or to prevent the accident occurance, but do not help to shorten the time span between this accident occurance and arrival of the rescue service. This function provides an emergency call system, which is capable of immediate automatic transfer of information about the accident via GSM network to the emergency call center. This transfer, unfortunately, could be disrupted by certain risk factors, which are experimentally evaluated in the article
