Google Maps for BlackBerry Offline Installers

Google Maps for Mobile

• Its location service can work with or without a GPS receiver. 
• The "my location" feature uses the GPS / Assisted GPS location of the mobile device, if available, supplemented by determining the nearest wireless networks and cell sites. 
• The software looks up the location of the cell site using a database of known wireless networks and sites. By triangulating the different signal strengths from different cell transmitters and then using their location property (retrieved from the online cell site database), My Location determines the user's current location. 
• Wireless network location method is calculated by discovering the nearby WiFi hotspots and using their location property (retrieved from the online WiFi database, in the same way as the cell site database) to further discover the user's location.
• The order in which these take precedence is:

1. GPS-based services
2. WLAN-, WiFi-based services 
3. Cell transmitter-based services 

The software plots the streets in blue that are available with a yellow icon and a green circle around the estimated range of the cell site based on the transmitter's rated power (among other variables). The estimate is refined using the strength of the cell phone signal to estimate how close to the cell site the mobile device is.
