LBS: Location Based Service
Different from traditional positioning services, e.g. car navigation and cargo tracking, LBS in mobile internet is Location Check-in Service.
- Depending on user’s ‘check-in’ behavior.
- Users care about what around them more than where they are.
- Foursquare.com in US, Digu.com and Jiepang.com in China
General LBS usage steps:
Open client software or webpage
Localize yourself by GPS etc.
Receive multiple locations (e.g. shop, restaurant)
Select one location to check
Use related services

Comparison of popular LBS tech & PAC
GPS/A-GPS/Base station
- inaccurate indoor position / need support of operator’s network / local info in server may not be updated timely
 Not good user experience
NFC
- very limited transmission range & discovery capability
PAC
- inaccurate indoor position  no effect on discovery result
- good discovery capability  up-to-date and comprehensive local information
- independent from operator’s network  easy to implement

Chinese LBS market
As the popularity of mobile internet and smart phone, the user number of LBS will be increasing as fast as 290.6% between 2010 and (by iResearch Inc.)
There will be estimated 81 million users in (by iResearch Inc.)
How much share of that big market will take?

Questions
LBS is a cluster of new applications originated from mobile internet, not mature enough.
For LBS, we need to distinguish what functions already has and what functions are still needed.
There are more interference and less unlicensed bands in the populous areas, heavy usage of LBS may cause delay and affect user experience.
