There are an estimated 300 million cell phones that are being used today in the United States. More and more households are abandoning their landline phones and relying only on wireless phones to save money.
When calling 911 on your wireless/cell phone, it is very important to know where you are. Current technology often provides excellent location information from these phones when you call 911. Sometimes the dispatcher will only receive an indication of which cell tower your phone is transmitting through.
