Remind scientists Hazards Satellite Navigation System


LONDON - The experts warn, a satellite navigation device on the accident risk of drivers of motor vehicles.

Mention the latest data, approximately 78 percent of accidents caused by driver carelessness. Psychologist at Lancaster University and Royal Holloway, University of London conducted an experiment to test the effects of hazards on the satellite navigation car navigation systems.

Using phone while driving is banned in the UK as well as several other countries. This is because mobile phone use can divert the driver's concentration and lead to accidents.

Now, the researchers wanted to examine other factors that could cause a car accident, including satellite navigation systems are used increasingly popular lately.

In this study, scientists analyze how the drivers handle the information they received from the satellite navigation systems and how they respond.

"At the end of the experiment, we see clearly that the use of navigation systems in cars has the potential to interfere with memory, concentration and attention and affect vehicle performance," said one researcher Polly Dalton, as quoted from the Telegraph, Monday (28/12/2009).

It is estimated there are approximately 14 million drivers who use satellite navigation system. Based on the data in 2008, survey of 2000 motorists to the conclusion that the satellite navigation system makes one of five people have faltered when the vehicle in a busy street. Satellite navigation system is also responsible for the condition of the vehicle can suddenly turn itself.

GSM Modems

A GSM modem can be an external modem device, such as the Wavecom FASTRACK Modem. Insert a GSM SIM card into this modem, and connect the modem to an available serial port on your computer.

A GSM modem can be a PC Card installed in a notebook computer, such as the Nokia Card Phone.

A GSM modem could also be a standard GSM mobile phone with the appropriate cable and software driver to connect to a serial port on your computer. Phones such as the Nokia 7110 with a DLR-3 cable, or various Ericsson phones, are often used for this purpose.

A dedicated GSM modem (external or PC Card) is usually preferable to a GSM mobile phone. This is because of some compatibility issues that can exist with mobile phones. For example, if you wish to be able to receive inbound MMS messages with your gateway, and you are using a mobile phone as your modem, you must utilize a mobile phone that does not support WAP push or MMS. This is because the mobile phone automatically processes these messages, without forwarding them via the modem interface. Similarly some mobile phones will not allow you to correctly receive SMS text messages longer than 160 bytes (known as "concatenated SMS" or "long SMS"). This is because these long messages are actually sent as separate SMS messages, and the phone attempts to reassemble the message before forwarding via the modem interface. (We've observed this latter problem utilizing the Ericsson R380, while it does not appear to be a problem with many other Ericsson models.)

When you install your GSM modem, or connect your GSM mobile phone to the computer, be sure to install the appropriate Windows modem driver from the device manufacturer. To simplify configuration, the Now SMS/MMS Gateway will communicate with the device via this driver. An additional benefit of utilizing this driver is that you can use Windows diagnostics to ensure that the modem is communicating properly with the computer.

The Now SMS/MMS gateway can simultaneously support multiple modems, provided that your computer hardware has the available communications port resources.
