Article Summary

December 21, 2005 In early 2005, a small group of hardcore GPS geeks (who were tired of their GPS devices not working in dense cities, urban canyons, indoors, etc) got together to come up with a solution that would enhance the performance of their GPS equipment and applications. The goal was to find a way to make GPS devices work in all situations. The result was Navizon Pocket PC Client Software. Now the group has developed an ingenious P2P network that enables people to accurately navigate urban and suburban areas using WiFi and a cellular devices (cell phones) - a dynamic, collaborative, networked "Wireless Positioning System" using wireless signals (Cellular and 802.11 WiFI). The Navizon Network is worth a look if you are a city dweller as it enables you to have accurate GPS on your mobile phone. The Navizon network is based on a collaborative database. Members with a GPS device can use Navizon to map the Wi-Fi and cellular landscape in their neighborhoods. Once they synchronize their data, it is made available to all the other users of the network. This way, users who don't have a GPS device can benefit from a positioning system. And it's free for personal use!
