Dear Congressman Coble: 
February 28, 2014 
Thank you for your letter regarding location accuracy requirements for E9ll calls placed 
from wireless devices- particularly calls made from indoor locations. As you point out, 
Americans are increasingly relying on their wireless phones, and rightfully expect that their 
emergency calls will bring the help that they need. When the original E911 rules for wireless 
providers were first adopted, they were built on the assumption that the primary place consumers 
would use their wireless phones would be outside. But today, the vast majority of wireless calls 
are made from indoors, including 9 I 1 calls made from wireless phones. 
In our ongoing rulemaking proceeding on E911 location accuracy, we have been 
exploring ways to ensure that the Commission's rules keep pace with technology and wireless 
911 calling trends, including the increase in wireless calls from indoor locations. Last week at 
the FCC's February 20 agenda meeting, the Commission unanimously adopted a Further Notice 
of Proposed Rule making in this proceeding. The Further Notice will seek comment on a 
proposal that wireless providers meet certain benchmarks for indoor location accuracy and 
proposes other changes to ensure that wireless providers are taking the appropriate steps to 
deliver accurate location information to 91 I call centers. 
I appreciate your interest in this matter. We will include your letter in the record of this 
proceeding for full Commission consideration. Please let me know if I can be of any further 
assistance. 
Sincerely, 
-:;;;~At
