SiRF's Multimode Location Platform Promises to Boost LBS Availability, Revenues

2007 - SiRF Technology Holdings, Inc. (NASDAQ:
SIRF), a leading provider of GPS-enabled silicon
and premium software location platforms, and
Skyhook Wireless, Inc., provider of the Wi-Fi
Positioning System (WPS), today announced that
SiRF has licensed the WPS in order to create a

Platform later this year, promises to boost the

WPS - WiFi : WiFi Positioning System
After WiFi assisted GPS, here comes WPS, full blown WiFi based positioning, courtesy of Skyhook Wireless. They present their Wi-Fi Positioning System as "the first outdoor positioning network to utilize Wi-Fi rather than GPS or cell tower systems to determine location" and claim an accuracy of up to 20 meters. Naturally WPS will only work in dense urban areas where there are many WiFi base stations.
Any comments ?
Updated 08/16
The AlwaysOn solution mentioned here in June has been further refined and is now called Navizon with the use of GSM in addition of WiFi to offer positioning assistance when the GPS signals are no longer strong enough. There is a free "collaborative" version and a "solo" version that costs $20.
Have you tried it ? Any questions or comments ?
Posted 06/08
With the deployment of A-GPS ("Assisted" GPS - technical details) somewhat in the "air", here comes AlwaysOnGPS, an innovative solution that uses WiFi to assist a GPS.
I have yet to try it, but the concept is simple enough, the software memorizes the position of WiFi base stations you come across as you would do for "war-driving", but instead of just mapping them out, their position can be used later to assist the GPS in case the signal gets lost and to increase accuracy. With the limited range of WiFi, it will likely only work well in dense urban areas, but that's also where GPS signals get blocked. You can give it a try with the 30 day trial version.
Questions, comments?

1. Wouldn't be much use out here in the suburbs in New Jersey, where WiFi access points are few and far between.
2. Given the large amount of power that WiFi tends to suck out of a PDA, I can't imagine using this system with a PDA on battery power exclusively. This would really limit its usefulness.

...and now with the power of SiRFstarIII GPS receivers we don't need that outdoor ;-) Some people may find it usefull indoor perhaps?

Possibly, I just tried it and I'm a bit disappointed with the lack of "monitoring" of what's going on, you just select the GPS port, and the virtual port (seems they're using GPSGate) and connect to that port using any GPS program. On the other hand it works on its own. True that SiRFIII holds a fix almost anywhere in Manhattan, but accuracy is sometimes pretty bad (150+ meters) so that might help, that's what their demo would tend to indicate.

I read on another site that you need to let it run for a day or two so it gets "familiar" with the environment (WiFi mapping i.e.) before it'll work. So no new places will work before using it there for a day at least. Not very useful for new places. Might as well use AGPS via Cellular/PCS network (or HDTV broadcast) instead.
However, it'll be interesting to be used in building (campus) like environment, with indoor maps (is there such thing? may be self made?) on the PDA.
Another thing is that WiFi will drain your PDA battery faster, not to mention it might (or might not) interfere with your GPS receiver (I know Haicom 303S in CF mode gets interference (RFI) from my Toshiba e830W if the WiFi is on).
Still very interesting a concept though, but I'd prefer PCS/cellular based solutions, as it's more practical.

It covers loss of sat signal when used in vehicles, but of course not usefull for anything else like cycling walking.

Right ;-)
Hopefully one day we will see accelerometers that can emulate the performance of acutal sensors, the TomTom GO raised a lot of hope with this, but alas, it is not very useful in the field.

Reviving this thread for the availability of a mobile version of Loki compatible with Windows Mobile PDAs, a bit of a surprise since Skyhook had mentioned at the 3GSM show that they would reserve it for mobile carriers. That's for the good news, the bad news is that I'm getting a "user authentication failed" message when I try to use it on my HP hw6915. Hope I can get it to work because the accuracy of the PC version is stunning in the SF Bay Area (tested in Sunnyvale so far).

Glad to see you guys have checked out Loki Mobile. If you are still receiving the "user authentication failed" message you will need to uninstall the current version. Then goto loki.com/download/mobile and download the latest version (0.9) and re-install.
Let me know if you guys have any other feedback or things you would like to see in future versions of Loki Mobile.
Best, Ryan

Just tried it on my Toshiba e830, works fine (mostly). Accurate in my place of Richmond, BC, Canada. But the Yahoo local search shows listing in Washington state (meaning they don't know what Canada is). The map shows up fine , and is precise on the location.
Still doesn't know how it works though, but it's quite neat to play with.
At least it installs fine on my e830, running WM 2003 SE. |

UPDATE : Skyhook's WPS (WiFi Positionning system) got in the news at the 3GSM 2007 show with their partnership with SiRF but no product has their technology has emerged yet. They did it again this year with Steve Jobs' announcement at MacWorld. We'll see what comes out of that agreement, but in the meantime we can use my.loki to share our position with the world, or at least anyone who's interested!
There are five position sharin modes that can be enabled or disabled individually and they each offer various levels of accuracy/privacy :
The my.loki plugin for your browser can update your position in the background, using wifi or ip data. |
