It is possible that the real obstacle to hinder the 3G smart phone to use as a satellite navigation device, at least the network providers to upgrade their network infrastructure to 4G. Will happen? The customer just needs to press the little button of cell phone jammer .
The smart phone market continues to grow in determining its ability to serve as a satellite navigation device is the ultimate key to the success factors. We should take the time to think about, this change will give the manufacturer What may be the impact? On the one hand, the smart phone device manufacturers and application developers to provide users free of TBT applications seems to be going as much as possible to carve up the market share from PND manufacturers. However, these manufacturers should never hazard a guess the psychology of consumers, that they will take the initiative to receive their set-in-one device.
