The scoop: Apple’s iPhone is NOT storing your accurate location, and NOT storing history - GeoThought Blog

"The quick summary: I believe I have confirmed that Apple is not storing your location, but the (actual or estimated) location of cell towers (and WiFi access points) that are close to you, to help locate you as you move (these are not necessarily towers that you have been in communication with). In the data I have examined there is nothing that is based on the accurate location of the iPhone. For a good example, see my previous post showing the location of cell equipment in Coors Field baseball stadium, and not revealing the location of my home which is very close to there. In my opinion, if Apple was storing this data in order to know where you had been, they would be storing different, more accurate location data that they have access to."

Podcast: A Hallway Conversation: Can you Locate me Now?

Did you ever wonder how hardware makers insure their devices can locate you effectively via GPS, cell towers and Wi-Fi? How do they answer the question “Can you locate me now?” One way is to use in-lab simulations for testing. Executive Editor Adena Schutzberg spoke with Nigel Wright, Spirent’s Vice President of Marketing for Wireless about how their testing services work and are used.

Skyhook’s Morgan: Screen Size Challenges GPS Signals, Turn by Turn too Expensive

Rafe Needleman interviewed Skyhook’s CEO Ted Morgan on the current state of things location, including FireFox going with Google’s toolkit and not Skyhook’s (not unexpected), the price of turn by turn directions in phones (too high), the need for location brokers like Fire Eagle (too early to know) and how the larger the screen in a device, the poorer the reception.

Furthermore, the bigger the screen of a device, the worse the GPS reception gets. Morgan says, “The bigger screens drown out the GPS signals.” Although when I pressed him as to why, and he claimed to not be technical enough to fully understand it.

Podcast: Hybrid Positioning and Your Future

Hybrid positioning refers to handsets that use GPS and another technology to determine the device’s location. Such solutions use Wi-Fi access points, cell towers, TV towers and their related signals, RFID, Bluetooth as a companion for when GPS is not enough. A recent report suggest growing use of hybrid solutions. What might your future and that of geospatial marketplace look like as these solutions proliferate? Our editors share some scenarios and point out gaps in the existing infrastructure, i.e., places to make money.

Hybrid Positioning Market Prediction

In a press release I must have missed from last week but which I think is significant, ABI Research offered predictions on the market potential of hybrid positioning systems. That is, when one form of position determination is not available, others must be available on the same handset. Dominique Bonte, ABI’s principal analyst for telematics and navigation (see my podcast interview with him from last August on LBS) states that, "Users expect a seamless and transparent location experience regardless of application or environment…Since no single positioning technology can provide this, the future will be about hybrid positioning systems, combining A-GPS, Cell-ID, Wi-Fi, cellular, motion sensors, and even TV broadcast and proximity technologies such as Bluetooth, NFC and RFID. A-GPS, Wi-Fi and Cell-ID will be the winning combination offering accuracy, availability, interoperability and short fix times at low cost. It will represent 25% of all positioning solutions by 2014. Stand-alone Cell-ID and/or Wi-Fi will remain important in regions with low GPS handset penetration."

So, here are a few questions:

1. What’s the size of the handset or chip set that must be equipped with all of these various positioning options?

2. Will there eventually be a nationwide network of just one or two technologies that win out over the long term?
