From:  Bryan Morgan's the statement from the Location Interoperability Forum at If your company is working in this area, sign

Global standard bodies and specification organisations are in the process of
defining and standardizing capabilities in the wireless networks for
determining and delivering the geographic location of wireless terminals and
devices. These capabilities are quickly being recognized as enablers of new
revenue, personalization, safety and convenience services for consumers,
network operators, and service providers worldwide.

In order for these services to be widely deployed and accepted by consumers
worldwide, the need for a simple, ubiquitous, and inter-operable location
services solution that is capable of determining and delivering the location
of mobile devices across the different wireless network boundaries becomes

Currently multiple location services solutions, both standards-based and
proprietary solutions, are being defined. In this situation operators are
faced with a difficult problem to select a solution, that will satisfy short
term needs, and is capable to evolve according to long term requirements.

Some issues to consider are:

How to locate legacy phones (with no existing positioning capability)
How to offer location services to roaming users (both visitors and own
How to support applications developed by various entities (such as in house,
3rd party developers, service providers)
availability of location capable terminals
interoperability of equipment and applications provided by multiple vendors
These issues are especially urgent to international operators operating
multiple networks, with possibly different standards (e.g. GSM&IS-136 and
GSM&IS-95), or to any operator with 3G plans and licences.

Most of currently marketed solutions address specific wireless technologies
and short term market requirements and lack inter-operability, simplicity,
long term evolution paths and may not be supported by major manufacturers
and operators.

In this situation there is a need to establish a global forum to address the
complexity and multiplicity of current solutions and market situation. The
forum should define, develop, and promote an inter-operable location
services solution that is open, simple, and secure. This solution allows
user appliances and internet-based applications to obtain location
information from the wireless networks independent of their air interfaces
and positioning methods.

With this purpose in mind, Motorola, Nokia and Ericsson would like to invite
you to join to the creation ofthe Location Inter-operability Forum (LIF).
LIF's purpose is to define, develop, and promote -through the global
standard bodies and specification organisations - a common and ubiquitous
location services solution. Such a solution will:

1. Define a simple and secure access method that allows user appliances and
Internet applications to access location information from the wireless
networks irrespective of their underlying air interface technologies and
positioning methods.

2. Promote a family of standards-based location determination methods and
their supporting architectures, that are based on Cell-ID and Timing
Advance, E-OTD (GSM), AFLT (IS-95), and MS Based Assisted GPS.

3. Establish a framework for influencing the global standard bodies and
specification organisations to define common methods and procedures for
testing and certifying the LIF-recommended access method and positioning

LIF intent is to have representation from a mix of network operators,
equipment manufacturers, and service providers responsible for deploying
equipment utilizing this solution. Its members will define this solution and
submit it to the working standards groups. The members will then support the
solution developed in the LIF in the appropriate existing global standard
bodies and specification organisations and in the deployment of their
systems and services.
