TRX has been working for some time to adapt and extend its sensor fusion and mapping algorithms to support indoor location using only embedded cellular device sensors.
Using sensor fusion, ranging, and mapping to deliver indoor location limits power consumption, allows delivery of location where no infrastructure or mapping exists, enables delivery of more seamless location (extending into parking garages, for example), and enables provision of dynamic updates to maps (structural changes, which happen with only limited frequency, but also changes to heat maps regarding typical user routes, and changes to WiFi or Bluetooth node locations).
The following is an example of tracking within a mall using the Nexus 5. Niether Wi-Fi mapping or floor plans are used to constrain location results.
As this path is being taken, NEON is collecting map data - structural information such as stairwells and elevators, as well as magnetic features, Bluetooth features, and Wi-Fi features. This information can be used to improve the location for others that revisit these same points in the future.

"Status of the MEMS Industry 2013", a new market report available from ReportsNReports, estimates that the overall MEMS market will be worth US$22.5B in 2018 (compared with US$11B in 2012), and the MEMS market for cell devices and tables alone will be worth $US6.4B in 2018.
This demand is, in part, driven by the demand for indoor location using embedded cell device sensors. TRX leverages accelerometer, gyroscope, pressure, compass and other embedded sensors to augment RF positioning, and in combination with higher level agorithms, deliver extended indoor location information when GPS is not reliable or unavailable (within buildings, dense urban areas, parking garages, metros, etc.). The MEMS market growth is particularly large for compact, combination sensors.
While restricted to higher end cell devices today, you can expect lower cost cell devices to increasingly incorporate sensors that are valuable for positioning. This proliferation of sensors is extending to other wearable accessories - smart watches, glasses, personal fitness devices & more. A recent Invensense developers conference showcased (in addition to the TRX NEON Indoor Location System) an array innovative sensor solutions, including devices from 3D Robotics, Variable Inc., Articulate Labs, Xensr, Makers with a Cause, GN Store Nord, Dysonics, ON Semiconductor, and zSpace.

A new research report studying the indoor location market estimates that it will experience a 42% growth rate - growing from $448.56 million in 2013 to $2.6 billion in 2018 ("Indoor Location Market: Global Advancements, Market Forecasts and Analysis", by Research and Markets). This is a tremendous growth rate, and it will impact virtually every segment of the technology market including enterprise networking, mobile platform, mobile infrastructure, mapping, and application providers.
The indoor location market is not at all one dimensional. Every industry segment - from mission critical government to consumer retail - is reliant on location based services, and each will benefit from access to more accurate location data. However, the requirements in each industry segment vary a great deal and this is driving an array of different solutions into the market.
Retailers and museums delivering applications for their customers can rely upon installed infrastructure and accurate indoor maps. Other applications being used in these same venues may not have access to such enterprise data, but can count on "signals of opportunity" (e.g., Wi-Fi that happens to be installed in the area). Mission critical applications often can't count on any infrastructure as all of it could fail during an emergency.
Solutions are emerging in islands, with pockets of mapped WiiFi delivering general location inside high use venues such as malls, airports, and museums. These island solutions provide a big leap in capability - enabling proximity-based retail services and effective information and navigation services. However, the ideal user experience is far more seamless - allowing continuous navigation throughout the mall, into the parking garage or metro, and into less frequently used venues such as office and residential buildings.
This seamless user experience requires the ability to seamlessly link islands of "globally known" locations - from GPS, Wi-Fi, Bluetooth, NFC, or from the user themselves via their application - with locations for which there is no globally known location or mapping data. In some cases, this link is for only a short period (between well mapped enterprises). In other cases, location must be calculated for extended periods.
TRX started its location work for mission critical applications, with the premise that it was necessary to deliver location for extended periods without infrastructure assist. As a result, the navigation approach used by the TRX NEON software performs dynamic mapping of venues - identifying structural features and signatures, and crowdsourcing this feature information - to quickly establish a comprehensive map of features that can be used as an input to location calculations. Through this approach the NEON navigation engine allows navigation for extended periods without any global location updates - building bridges between the islands.

I am often asked about the commercial applications for indoor location. “Why would anyone need to locate indoors?"
It can be tough to envision applications that might be generated through capabilities you don’t have. GPS was first funded and deployed for military applications. Without the defense push for GPS the business case for investment would have been very difficult to make. However, the overall market for GPS devices and systems is now expected to grow to over 240 Billion dollars by 2013 (ABI Research) – and a good part of that is driven from the civilian sector.
Indoor location has also been initially driven by Government and Public Safety applications where the demand is the greatest. However, during day two of the WPI Precision Indoor Location and Tracking Workshop, both Qualcomm and Verizon spoke about the immense potential for the consumer indoor location market. Applications discussed included navigation applications within transportation hubs, shopping malls, convention centers, university campuses, hospitals, and office buildings, along with entertainment and social applications. Should we really have to wander around looking for “you are here” signs to find a decent restaurant? I don’t think so. And at some point we will all stop walking around with phones to our ears while we are almost bumping into the person we are supposed to meet.
Today, we can detect proximity from Wi-Fi, but we can’t get to precise indoor location. This is the “last mile” for the location services market. While a number of tagging & infrastructure-based technologies can deliver to precise indoor location, it is tough to make these solutions ubiquitous. At WPI, the view from Qualcomm and Verizon appeared to be that simplicity may win out over precision, and that innovations that depend less on infrastructure may win out.
Regardless of the commercial potential to make our lives more convenient and entertaining - and in TRX’s case to increase the size of the market we are addressing - real lives will be saved by delivering GPS-denied location for the military and public safety markets. At TRX, we remember that every day.

ABI Research predicts, in their "Alternative Positioning Technologies" study that the alternative location technologies market will be $2.5 Billion by 2015 - delivering location to applications while people are indoors, underground, or in dense urban areas where GPS does not work effectively.
"The demand for low cost, ubiquitous location data has increased significantly over the last 12 months. Companies such as Google, Microsoft, Apple, Nokia, Facebook and others are battling to enable and control consumer location”, said ABI Research senior analyst Patrick Connolly. “This will bring new opportunities and threats to the market but ultimately will drive a 400% increase in alternative location technology penetration across a range of portable devices, location technologies and location providers."
The indoor location market is divided among a myriad of approaches, including Wi-Fi positioning which already has a large installed base in cell phones. However, Wi-Fi solutions don't deliver precise indoor location and cannot provide 3D - i.e., the location within a building including floor level - without enterprise surveying and involvement. Infrastructure-free location at that level of accuracy requires the use of sensors beyond GPS and Wi-Fi.
According to EETimes "It’s not a case of either/or, but of, a continually evolving hybrid approach. GPS alone will not be sufficient to support the next generation of services and revenue streams. Services such as local search, location-based advertising, geotagging, social networking and augmented reality are all significantly improved through increased accuracy and indoor/ubiquitous location."

TRX has announced it is working with with DARPA to optimize its Sentrix Personnel Tracking System to support location and tracking in undergound structures such as caves and mines. The DARPA program supports testing and optimization that enables TRX to enhance the navigation accuracy of the system in such subsurface environments. The funding will also enable the Sentrix system and its sensors to be easily integrated into existing systems with sensors already in place.
