Indoor Location Technology Test Results Submitted to FCC (6/24/14)

The results of an independent study of indoor tests of a hybrid wireless location technology were submitted to the FCC. Wireless location engineering firm TechnoCom submitted the study, which the sponsor said demonstrates that existing technologies can satisfy location requirements within the timeframe proposed by the FCC in its draft rule on indoor 9-1-1 accuracy for wireless calls.

The FCC proposed the new indoor location accuracy rules for 9-1-1 calls in February. With more than 40 comments filed in response to the FCC’s new rules for 9-1-1, about half the commenters said the technology and standards are not in place to support the rules, while public-safety officials applauded the rules.

The tests were conducted using TruePosition's commercially available uplink time difference of arrival (UTDOA) technology standalone and a hybrid solution consisting of assisted GPS (A-GPS) and UTDOA technologies. The tests included indoor testing in urban and suburban environments in Wilmington, Delaware, and surrounding areas.

For the testing, TechnoCom selected buildings of varying sizes, construction materials and use, and a total of 62 test points were selected among 16 buildings. In all cases, the test buildings and test points remained anonymous to TruePosition until the conclusion of the testing and delivery of all results to the independent firm.

In early 2013, TechnoCom conducted the indoor accuracy testing for the FCC's Communications, Security, Reliability and Interoperability Council (CSRIC). The same location and measurement methodologies were used in these tests.

"The outcome is a current overall performance that readily meets the FCC's proposed location performance threshold for indoor wireless enhanced 9-1-1 (E9-1-1) at the 67th percentile,” the results said. “The demonstrated performance even comes very close to meeting the 50 meter threshold at 80 percent, which is intended for five years from adoption of the proposed rules."

Other vendors have submitted filings to the FCC claiming that their technologies would also satisfy the requirements of the rule on the timeline proposed by the FCC.

"These results should prove helpful to the FCC as it moves toward reaching a resolution on its proposed rule on indoor location requirements," said Craig Waggy, CEO of TruePosition. "We know that accurate location information is vitally important to American consumers, and that the FCC is intent on remedying the lack of wireless indoor location requirements for calls placed to 9-1-1 from wireless devices."
