Kansas Gov. Kathleen Sebelius signed a bill into law that charges mobile telephone users in the state fees to fund improvements in county 9-1-1 systems.

The new law, which takes effect July 1, will add 50 cents a month to wireless telephone bills, The Kansas City Star reported. The funds will be used to upgrade emergency communications systems across the state to make it easier to locate someone making an emergency call on a wireless phone.

Enhanced 9-1-1 is a service that allows emergency dispatchers to pinpoint the location and phone number of a person without the caller having to say a word. Such service is already available to callers using land-line phones; those phone users now pay 75 cents a month to finance dispatch operations.

Under the new law, 25 cents will go to each wireless phone customer’s home county and 25 cents will go to rural counties that have relatively few wireless phone users.

At $6 a year, the fee is expected to bring in $7.2 million annually, the newspaper reported. The revenue can be used only to purchase, operate and maintain the enhanced 9-1-1 equipment used by law enforcement and emergency personnel.
