Abstract
Urgency calls applications, encouraged by regulations E911/E112, recently
led communication carriers to develop systems allowing a guaranteed
location
of mobile terminals. Location must be carried out in all the environments
covered by the communication service, including the most constraining
areas
such as deep indoor environments. This location capability, combined with
a
data transfer service, opens the way for a new market named LBS ("Location
Based Services"). The development perspectives of this market are
exponential, but positioning systems designers face significant
constraints
to meet performances requirements of urban and indoor applications.

LBS has been knocking around for 6 or 7 years now in one form or another on
most GSM networks. Certainly all the W-CDMA networks have location servers
and most of the existing GSM networks.

The problem is money making apps and the client applications to take
advantage of them.
