GPRS (General Packet Radio Service) is an extention of the GSM network allowing you to use it for data transport to the internet. GPRS uses unused GSM-cell bandwidth to transmit the data. As phone-calls have precedence for this bandwith, transmission speed might drop drastically when you enter busy cells. Regular transmission speeds vary between 30–80 kbit/s,
GPRS has the possibility to be always on. Because it is package-switched, most operators will not bill you for the time spent on the internet, but will bill you for the amount of data used. To conserve energy use, the device connection will enter a sleep mode after a given period (decided by the cell-tower). So even when the device is on and connected, it does have to power up some hardware before you can browse the web again.
GPRS is in practice quite robust: it will switch cells while on the move and a connection will even survivive a small black-out in the connection. GPRS also works abroad, allowing you to connect to your favourite information sources whenever you need to.
There are several ways you can use GPRS:
- Use it for connecting your Windows Mobile Phone Edition device to the internet
- Use a seperate GPRS phone to connect your windows mobile device to the internetÂ
- Use it for connecting your laptop to the internet by using your windows mobile device as a bluetooth modem or bluetooth access point
