Technology Review (Published by MIT) published an article on Monday titled "A New Microchip Knows Just Where You Are, Indoors and Out". The article goes on to describe how Broadcom is attempting to deliver unprecedented accuracy in indoor positioning via multiple sensors on a mobile phone. The author, Christopher Mims, does a terrific job in describing the chip-makers approach to solving the indoor positioning problem.The entire article has been re-published below. 
Broadcom has just rolled out a chip for smart phones that promises to indicate location ultra-precisely, possibly within a few centimeters, vertically and horizontally, indoors and out.
The unprecedented accuracy of the Broadcom 4752 chip results from the sheer breadth of sensors from which it can process information. It can receive signals from global navigation satellites, cell-phone towers, and Wi-Fi hot spots, and also input from gyroscopes, accelerometers, step counters, and altimeters.
The variety of location data available to mobile-device makers means that in our increasingly radio-frequency-dense world, location services will continue to become more refined.
In theory, the new chip can even determine what floor of a building you're on, thanks to its ability to integrate information from the atmospheric pressure sensor on many models of Android phones. The company calls abilities like this "ubiquitous navigation," and the idea is that it will enable a new kind of e-commerce predicated on the fact that shopkeepers will know the moment you walk by their front door, or when you are looking at a particular product, and can offer you coupons at that instant.
The integration of new kinds of location data opens up the possibility of navigating indoors, where GPS signals are weak or nonexistent.
Broadcom is already the largest provider of GPS chips to smart-phone makers. Its new integrated circuit relies on sensors that aren't present in every new smart phone, so it won't perform the same in all devices. The new chip, like a number of existing ones, has the ability to triangulate using Wi-Fi hot spots. Broadcom maintains a database of these hot spots for client use, but it says most of its clients maintain their own.
A company that pioneered the construction and maintenance of these kinds of Wi-Fi hot spot databases is SkyHook Wireless. Skyhook CEO Ted Morgan is skeptical that Broadcom can catch up to his company's software-based system allowing for precise indoor location. "Broadcom is just now talking about something we have been doing for seven to eight years, uncovering all the challenges," says Morgan. These include battery management and cataloging a new wave of mobile Wi-Fi hot spots. "Broadcom has never done major deployment," adds Morgan.
Scott Pomerantz, vice president of the GPS division at Broadcom, counters that "the big [mobile] operating systems all have a strategy in place" to create their own Wi-Fi databases. Pomerantz isn't allowed to name names, but one of Broadcom's biggest customers is Apple, which previously used Skyhook for location services in its iPhone but now employs its own, Apple-built location system.
At least one feature of Broadcom's new GPS chip is entirely forward-looking, and integrates data from a source that is not yet commercially deployed: Bluetooth beacons. (Bluetooth is the wireless standard used for short-range communications in devices like wireless keyboards and phone headsets.)
"The use case [for Bluetooth beacons] might be malls," says Pomerantz. "It would be a good investment for a mall to put up a deployment—perhaps put them up every 100 yards, and then unlock the ability for people walking around mall to get very precise couponing information."
"The density of these sensors will give you even finer location," says Charlie Abraham, vice president of engineering at Broadcom. "It could show you where the bananas are within a store—even on which shelf there's a specific brand."

Reverse geocode indoors? Find out how at the O'Reilly Where Conference next week!

The O'Reilly Where Conference 2012 is happening in San Francisco, April 2-4 at the San Francisco Marriott Marquis Hotel. Micello's CTO Dave Sutter will be on hand discussing how to reverse geocode indoors. This is a hot topic that will answer many questions centered around indoor location based services. Don't miss this Location Development Session, Wednesday April, 4th at 1:10pm in the Yerba Buena Salon 9.

When developers work with an outdoor map they place annotations on the map using postal addresses and latitude/longitude points. Working with indoor maps, there is no longer a convenient globally defined address scheme or even a positioning coordinate system. This talk discusses the framework for a developer to place real world objects on an indoor map.  

The O'Reilly Where Conference brings together the people working on and using location technologies to come together to explore best practices and emerging trends in software development, tools, business strategies, and marketing. CTOs, marketers, developers, technologists, researchers, geographers, startups, business developers, and entrepreneurs gather to share their experiences and learn from their peers in the areas of Mobile Development, Location Development, Business and Strategy and Marketing.

Location is big business, and location data is even bigger business. Find out more about Where conference 2012 here.

Arkansas's largest commercial service airport has been renamed to honor two of the state’s most well-known citizens, former President Bill Clinton and Secretary of State Hillary Clinton.

The newly named, Clinton National Airport, serves over two million passengers a year and spans over 2,000 acres. Currently under construction for expansion, going from 12 to 16 gates, the airport contains three runways, one helipad, and has plans of becoming an international airport by 2020.

How do the Clinton's feel about the new namesake? Bill Clinton said in a statement, "Hillary and I are humbled by the Little Rock Airport Commission's decision ... We are grateful for this honor and for all that the people of Arkansas have done for us. And we look forward to many happy landings at the airport in the years ahead."

We couldn't be happier to annouce that micello has been listed in the Data 2.0 list of Top 100 Innovators. Each year the Data 2.0 advisory board selects companies based on the top cloud data products in their industry, companies who publish the most respected thought leadership editorial in the cloud data industry, and companies who are ahead of the curve in developing potentially disruptive products and services. Micello is happy to be in the running for the top prize at Data 2.0 in April, 2012. You can see the full list of the Top 100 Innovators here.

Last year at the Data 2.0 Conference 2011, over 500 participants from over 200 tech companies were all under one roof to discuss the new online data ecosystem of API’s, social data, geo data, data-as-a-service, and big data. Ankit Agarwal, Founder & CEO at micello, spoke about indoor mapping and micello APIs. His presentation was not only highly applauded, it was awarded as the winner of the Data 2.0 Startup Competition.
