people in the social structure can share location-
embedded information

the interdependency derived from their locations in the
physical world as well as their location-tagged media
content, such as photos, video, and texts

7. Mobile Social Network
 Social network where users can connect with another one through
their mobile phone and/or tablet
 The increasing availability of open smartphone platforms such as Apple
iPhones and Google Android phones caused that mobile device users
use mobile applications to share their current location with their
friends via Location-Based Social Networks (LBSN)
 The process of sharing current location has became known as
“checking - in”
 Check –in can be gained in one of two ways:
 via an SMS text message,- manualy
 via mobile application - automatically determine a user’s current
location by leveraging the power of a number of location determination
technologies

(Železniční stanice Olomouc-Hlavní nádraží, Hlavní
nádraží, Olomouc Hlavní nádraží, ČD Centrum)
