P-Cell Technology -New locator Alternative for LBS

KOREA: This time, a development to report on from Korea, where in 2007 a patent was published for a new type of locator technology for a 'network-based Location measurement method...using P-Cell database'.

Not being a technical sort of guy, and this being a very new technology, I will leave it up to the engineers out there to correct me if I am wrong, but my understanding is as follows:

This technology attempts to overcome the issues surrounding location triangulation using conventional Cell ID...namely, accuracy and reliance on operator network cell size parameters.

Instead, the new technology divides an area into pre-defined 'lattices'of a predetermined size which are mapped in a P-Cell database (where the P stands for Parametrized).

Then it continuously determines whether a request for location measurement occurs by a service subscriber; and when the request for location measurement is generated, it compares fundamental information received from a mobile terminal with the P-Cell database, determines a matching P-Cell, and reports the matching P-Cell to the service subscriber.

The advantages are that indoor location fixes are improved by about 70% (or so the technology patent says).

As far as I can determine, the system works like standard base tower signal triangulation (or trilateration, to be more precise) but instead of using the operator's cell tower signal radii, it uses 'lattices' of a standard dimension.

I have asked Tom Tierney from Navteq to shed more light on this technology and welcome any comments from readers who wish to add more information, particularly whether any testing has been carried out outside of Asia.

Either way, a key point is that location on mobile will increasingly become ubiqitous and most likely by offering subscribers a choice from a range of alternatives to ensure they can access location services wherever they may be.

Future of Location Based Services...according to Navteq

BARCELONA -I was at the Forum Nokia Camp in Barcelona today and attended the presentation by Tom Tierney, Developer Alliance Manager at Navteq, based in Chicago.

Here are some tidbits from his presentation:

• Referring to the difference between PNDs (Personal Navigational Devices) and mobiles, Tom described the mobile device as being the 'navigational ringtone' for the user and sees the PNDs and mobiles to be complimentary instead of competing for the same audience

• Some new technologies not everyone has heard of yet were discussed -namely P-Cell Technology (developed in Korea) and TV-GPS Hybrid Positioning...I will investigate and report back if there are interesting developments in these areas

• According to Tom, the use of audio, touch screens and voice interactivity will eliminate the need for banner ads in the future

• Unsurprisingly perhaps, Tom stated that LBS's will be ubiqitous in the future. Also, according to Navteq's own research, consumers principally want 3 things from them -for them to be cheap, accurate and easy-to-use

• According to Navteq, consumers will pay for navigation and gaming applications but not for social networks and search (in line with internet trends)

• To put figures to the growth opportunity we are talking about here, in Q1 2008, 43% of all downloads on mobile phones globally were for Location Based Services..accounting for 62% of total revenues...a sizeable pie which is clearly growing as we see LBS being demanded for Resource Management or Asset Tracking, Entertainment (including Location based dating) and Security (Child Finder features etc.)
