e9-1-1 Phase Two location technology

When you dial 9-1-1 in areas where e9-1-1 Phase Two is available, your location is provided to emergency operators. Télébec mobile devices that support e9-1-1 Phase Two can use either the Global Positioning System (GPS) or cell-site triangulation to provide location information depending on the model and the reception conditions.

Some Télébec mobile devices support both GPS and cell-site triangulation and others support only cell-site triangulation. When you dial 9-1-1 in areas where e9-1-1 Phase Two is available, the location system automatically selects the best method to determine your location. Please check the e9-1-1 Phase Two compatibility list to see if your Télébec mobile device is supported. If your mobile device is not supported you can still dial 9-1-1 as you will still be supported by e9-1-1 Phase One.

GPS uses radio signals from satellites to calculate the mobile device’s location (similar to car navigation systems). GPS radio signals may be affected by weak signals, in covered areas or underground areas.

For e9-1-1 Phase Two capable mobile devices that do not support GPS or when GPS signals are weak or not available, cell-site triangulation is used. Cell-site triangulation uses radio signals from cell towers to calculate the mobile’s location. Cell-site triangulation may be affected by weak signals, in covered areas or underground locations. It also may be limited in areas served by fewer than three cell towers (e.g., in remote rural areas).

When calling 9-1-1, always give the operator your name, mobile device number (including the area code), and location, in case you are in an area not equipped with mobile e9-1-1 service.
