Alltigo's Location Tag LT100 uses small GPS and GSM/GPRS for location services
The Alltigo Location Tag LT100 is a small, location-aware electronic device that enables the global positioning of a person, vehicle or any other kind of mobile asset with an accuracy of a few meters. The LT100 communicates its location and receives commands over a GSM/GPRS mobile phone network via TCP/IP or SMS. To activate the device, a standard SIM card from a local service provider is all that is needed. No additional monthly services are required in most cases. The LT100’s exclusive AAGPS (Adaptive Assisted GPS) technology enables positioning even in environments with restricted satellite signal availability.

With its small size and weight of only 50 grams, the Location Tag LT100 is easy to carry. The device can be used for tracking children or disabled people, or in enterprise applications in which personal location is crucial for conducting business. In vehicles, the Location Tag can be used as a security measure that enables the owner to locate the vehicle in the event of theft.

“The Location Tag is a hybrid of two wireless technologies, using GPS to obtain the global location of the device and wireless GSM networks to pass that location to another mobile phone or location-enabled enterprise system,” said Mr. Nenad Lazovic, Engineering Director, Alltigo Inc. “Most similar devices suffer from the traditional GPS limitation that the satellite signal can be detected only if there is a clear line of sight to the sky. However, Fastrax’s sophisticated GPS receiver, combined with our exclusive AAGPS™ software, enables the LT100 to locate satellites even from inside concrete buildings, between high-rise buildings or under trees. This positions the LT100 as a unique product in a class of its own. All this comes in a solution that in most usage scenarios does not require any monthly service apart from a GSM/GPRS data connection.”

The Location Tag LT100 does not have a keypad or display of its own. Instead, the device is controlled with commands issued through a cell phone or computer. The various options for controlling the Location Tag include the Location Tag Monitor Instant Messaging application; the Location Tag Monitor - Mobile Edition application for Java-enabled cell phones; and the Location Tag SDK, which allows the device interface to be integrated into enterprise applications. Additionally, the device can be controlled through a simple command language transmitted via standard mobile phone SMS messages.

The company also supplies two applications, Location Tag Monitor and Location Tag Monitor Mobile. The Java application can be used to monitor and track Location Tags owned or controlled by the user. It works same way as other Instant Messengers (like Yahoo Messenger, AIM, MSN Messenger). The difference is that LT Monitor list contains Location Tags instead on-line friends. It always shows where all Location Tags from your list are or where they have been in the past. The user can set thresholds which will trigger alert messages if any of the location parameters, such as distance, speed, or even movement goes over previously set values.
