Senior GPS tracker Phone dual SIM card
Over the past several years, we have witnessed an impressive change in the size and capabilities of cellular phones and their individual components. First generation cellular phones for analog cellular networks were very big and for voice processing only. Today, on the other hand, Over the past several years, we have witnessed an impressive change in the size and capabilities of cellular phones and their individual components. First generation cellular phones for analog cellular networks were very big and for voice processing only. Today, on the other hand, The tracking devices for people is a key hardware component for any LBIS utilizing the mobile-based location provider architecture, like the real-time tracking system example described in this blog.
The GPS receiver is important not only because no position will be available to the application without it but also because of its features and performance. There is always the trade-off between cost and quality, and the GPS chip is not the exception. Accuracy and energy consumption are usually traded off for lower prices, so the chips can be integrated in as many devices as possible. It is the application service provider’s responsibility to test their applications in the supported devices and assess whether the accuracy and performance provided by the GPS receiver meet the application’s requirements or not. Bear in mind that some applications need very precise GPS fixes while others may have more relaxed requirements and cellular phones may provide very different levels of accuracy. Power consumption is another important issue that application service providers should look into. Having the GPS receiver always on and transmitting GPS fixes very frequently will tend to drain the cellular phone’s battery very fast. Therefore, some ways to make the application more energy efficient while meeting the tracking requirements of the application need to be devised.
Cellular phones using the GPS system rely on the good reception of the radio signals from the GPS satellites. This is particularly challenging in indoor environments where the satellite signals, because of obstructions, are of very poor quality, if received at all. Under these conditions, some GPS-enabled cellular phones might not be able to calculate their position. Although indoor positioning systems have been designed to fill this gap, the integration and collaboration between outdoor and indoor positioning systems so that the mobile station can determine its position at any time in any place, is still an active area of research.
GPS senior phone is a powerful personal tracking device, which is specially designed for the elderly. It works on existing GSM/GPRS network and GPS satellites. Besides traditional multi-media usage, the tracking devices for people is also equipped with functions like real-time position tracking (SMS/APP/PC), SOS emergency calling, FM radio, Geo-fence alarm, electric torch, remote monitor, etc.
You can log on to platform or use APP in your cellphone to check the location of the GPS tracker. LBS is location based service, accuracy 50m to 300m. GPS accuracy around 10M. The platform service is turned on as default.
Note: when the platform service is on and the phone is disconnected with platform for some reasons, the senior phone will restart automatically 20 minutes later to try reconnect with the server. Usually there are two reasons: a, the GPRS function of the SIM is not activated b, GPRS connection timeout.
