Existing Technology Can Meet Proposed Standards for Indoor Location Accuracy

Published on:

A study of indoor tests of a hybrid wireless location technology was submitted to the US telecoms regulator which claims 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.

Multiple wireless carriers have challenged the technical feasibility of the proposed rule, claiming that existing technologies cannot satisfy the proposed accuracy requirements, with a spokesperson for the industry trade association claiming the rule represented "aspirational target setting."

TechnoCom says that the results of its study disprove those assertions, showing that viable technology exists in the market today.

According to TechnoCom's findings, "The outcome is a current overall performance that readily meets the FCC's proposed location performance threshold for indoor wireless E911 at the 67th percentile. The demonstrated performance even comes very close to meeting the 50 meter threshold at 80%, which is intended for 5 years from adoption of the proposed rules."

Multiple 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."

The tests were conducted using TruePosition's commercially available Uplink Time Difference of Arrival (UTDOA) technology standalone, and a hybrid solution consisting of Assisted Global Positioning System (A-GPS) and UTDOA technologies, and included indoor testing in both urban and suburban environments in Wilmington, Delaware and surrounding areas.

For the testing, buildings of varying sizes, construction materials and use were selected by the independent firm, 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.
